  Abstract
  
  Background:
  Robust data on case fatality rate (CFR) among inpatients with COVID-19 are still lacking, and the role of patient characteristics in in-hospital deaths remains under-investigated. This study quantified the overall CFR and described its trend in a cohort of hospitalized patients with SARS-CoV-2 in Italy. Admission to ICU, death, or discharge were the secondary outcomes.
  
  Methods:
  This retrospective study is based on administrative health data and electronic case records of inpatients consecutively admitted to Niguarda Hospital between 21 February and 8 November 2020.
  
  Results:
  An overall CFR of 18% was observed. CFR was significantly reduced during the second wave of contagion (1 June to 30 September, 16%) compared with the first wave (21 February to 31 May, 21%  = 0.015). Such reduction was mainly observed among male inpatients between 40 and 80 years with limited comorbidities. Admission to ICU was associated with a high risk of mortality in both waves. The incidence of severe disease and the need for ICU admission were lower in the second wave.
  
  Conclusion:
  CFR in SARS-CoV-2 inpatients was demonstrated to decrease over time. This reduction may partly reflect the changes in hospital strategy and clinical practice. The reasons for this improvement should be further investigated to plan an exit strategy in case of future outbreaks.
  
  Key messages:
  Before the advent of anti-COVID-19 vaccines, a multi-wave pattern of contagion was observed, and this trend conditioned the inpatient case fatality rate (CFR), which varied over time accordingly to the waves of contagion.Only preliminary results on the in-hospital mortality trend are available, along with a partial analysis of its determinants. Consequently, robust data on CFR among inpatients with SARS-CoV-2 infection are still lacking, and the role of patient characteristics in in-hospital deaths remains under-investigated. This study shows that the in-hospital mortality in patients with SARS-CoV-2 infection decreases over time.Such reduction was mainly observed among male inpatients between 40 and 80 years with limited comorbidities. Admission to ICU was invariably associated with a high risk of mortality during the whole study period (21 February to 8 November 2020), but the incidence of severe disease and the need for ICU admission were lower in the second wave of contagions (1 October to 8 November 2020). This reduction may partly reflect the impact of changes in hospital strategy and clinical practice. The reasons for this improvement should be further investigated to inform the response to future outbreaks and to plan exit strategy by prioritizing high-risk populations.

  Abstract
  
  OBJECTIVES:
  In older individuals, the role of serum uric acid (SUA) as risk factor for mortality is debated. This study investigated the association of SUA with all-cause and cardiovascular (CV) mortality in older adults participating in the large multicentre observational uric acid right for heart health (URRAH) study.
  
  METHODS:
  Eight thousand URRAH participants aged 65+ were included in the analysis. The predictive role of SUA was assessed using Cox regression models stratified according to the cut-off age of 75. SUA was tested as continuous and categorical variable (age-specific quartiles). The prognostic threshold of SUA for mortality was analysed using receiver operating characteristic curves.
  
  RESULTS:
  Among participants aged 65-74, multivariate Cox regression analysis adjusted for CV risk factors and comorbidities identified an independent association of SUA with both all-cause mortality (hazard ratio [HR] 1.169, 95% confidence interval [CI] 1.107-1.235) and CV mortality (HR 1.146, 95% CI 1.064-1.235). The cut-off value of 4.8?mg/dl discriminated mortality status. In participants aged 75+, we observed a J-shaped relationship of SUA with all-cause and CV mortality, with risk increasing at extreme SUA levels.
  
  CONCLUSIONS:
  These results confirmed the predictive role of SUA for all-cause and CV mortality in older adults, while revealing considerable age-related differences. Mortality risk increased at higher SUA levels in participants aged 65-74, with a prognostic threshold of 4.8?mg/dl. The relationship between SUA and mortality was J-shaped in oldest participants. Large interventional studies are needed to clarify the benefits and possible risks of urate-lowering treatments in older adults.

  Abstract
  
  The most common arrhythmia associated with COronaVIrus-related Disease (COVID) infection is sinus tachycardia. It is not known if high Heart Rate (HR) in COVID is simply a marker of higher systemic response to sepsis or if its persistence could be related to a long-term autonomic dysfunction. The aim of our work is to assess the prevalence of elevated HR at discharge in patients hospitalized for COVID-19 and to evaluate the variables associated with it. We enrolled 697 cases of SARS-CoV2 infection admitted in our hospital after February 21 and discharged within 23 July 2020. We collected data on clinical history, vital signs, laboratory tests and pharmacological treatment. Severe disease was defined as the need for Intensive Care Unit (ICU) admission and/or mechanical ventilation. Median age was 59 years (first-third quartile 49, 74), and male was the prevalent gender (60.1%). 84.6% of the subjects showed a SARS-CoV-2 related pneumonia, and 13.2% resulted in a severe disease. Mean HR at admission was 90 ± 18 bpm with a mean decrease of 10 bpm to discharge. Only 5.5% of subjects presented HR > 100 bpm at discharge. Significant predictors of discharge HR at multiple linear model were admission HR (mean increase = ? = 0.17 per bpm, 95% CI 0.11; 0.22,

  Abstract
  
  Central (aortic) systolic blood pressure (cSBP) is the pressure seen by the heart, the brain, and the kidneys. If properly measured, cSBP is closer associated with hypertension-mediated organ damage and prognosis, as compared with brachial SBP (bSBP). We investigated 24-hour profiles of bSBP and cSBP, measured simultaneously using Mobilograph devices, in 2423 untreated adults (1275 women; age, 18-94 years), free from overt cardiovascular disease, aiming to develop reference values and to analyze daytime-nighttime variability. Central SBP was assessed, using brachial waveforms, calibrated with mean arterial pressure (MAP)/diastolic BP (cSBP), or bSBP/diastolic blood pressure (cSBP), and a validated transfer function, resulting in 144?509 valid brachial and 130?804 valid central measurements. Averaged 24-hour, daytime, and nighttime brachial BP across all individuals was 124/79, 126/81, and 116/72 mm?Hg, respectively. Averaged 24-hour, daytime, and nighttime values for cSBP were 128, 128, and 125 mm?Hg and 115, 117, and 107 mm?Hg for cSBP, respectively. We pragmatically propose as upper normal limit for 24-hour cSBP 135 mm?Hg and for 24-hour cSBP 120 mm?Hg. bSBP dipping (nighttime-daytime/daytime SBP) was -10.6 % in young participants and decreased with increasing age. Central SBP dipping was less pronounced (-8.7% in young participants). In contrast, cSBP dipping was completely absent in the youngest age group and less pronounced in all other participants. These data may serve for comparison in various diseases and have potential implications for refining hypertension diagnosis and management. The different dipping behavior of bSBP versus cSBP requires further investigation.

  Abstract
  
  Uric acid (UA) is the final product of the catabolism of endogenous and exogenous purine nucleotides. While its association with articular gout and kidney disease has been known for a long time, new data have demonstrated that UA is also related to cardiovascular (CV) diseases. UA has been identified as a significant determinant of many different outcomes, such as all-cause and CV mortality, and also of CV events (mainly Acute Coronary Syndromes (ACS) and even strokes). Furthermore, UA has been related to the development of Heart Failure, and to a higher mortality in decompensated patients, as well as to the onset of atrial fibrillation. After a brief introduction on the general role of UA in CV disorders, this review will be focused on UA's relationship with CV outcomes, as well as on the specific features of patients with ACS and Chronic Coronary Syndrome. Finally, two issues which remain open will be discussed: the first is about the identification of a CV UA cut-off value, while the second concerns the possibility that the pharmacological reduction of UA is able to lower the incidence of CV events.

  Abstract
  
  Serum uric acid predicts the onset and progression of kidney disease, and the occurrence of cardiovascular and all-cause mortality. Nevertheless, it is unclear which is the appropriate definition of hyperuricemia in presence of chronic kidney disease (CKD). Our goal was to study the independent impact of uric acid and CKD on mortality. We retrospectively investigated 21,963 patients from the URRAH study database. Hyperuricemia was defined on the basis of outcome specific cut-offs separately identified by ROC curves according to eGFR strata. The primary endpoints were cardiovascular and all-cause mortality. After a mean follow-up of 9.8 year, there were 1,582 (7.20%) cardiovascular events and 3,130 (14.25%) deaths for all causes. The incidence of cardiovascular and all-cause mortality increased in parallel with reduction of eGFR strata and with progressively higher uric acid quartiles. During 215,618 person-years of follow-up, the incidence rate for cardiovascular mortality, stratified based on eGFR (>90, between 60 and 90 and

  Abstract
  
  The Working Group on Uric Acid and Cardiovascular Risk of the Italian Society of Hypertension conceived and designed an ad hoc study aimed at searching for prognostic cut-off values of serum uric acid (SUA) in predicting combined (fatal and non-fatal) cerebrovascular (CBV) events in the whole database. The URic acid Right for heArt Health study is a nationwide, multicenter, observational cohort study involving data on subjects aged 18-95 years recruited on a regional community basis from all the territory of Italy under the patronage of the Italian Society of Hypertension with a mean follow-up period of 120.7?±?61.8 months. A total of 14,588 subjects were included in the analysis. A prognostic cut-off value of SUA able to discriminate combined CBV events (>4.79?mg/dL or >284.91?µmol/L) was identified by means of receiver operating characteristic curve in the whole database. Multivariate Cox regression analysis adjusted for confounders (age, sex, arterial hypertension, diabetes, chronic kidney disease, smoking habit, ethanol intake, body mass index, low-density lipoprotein cholesterol, and use of diuretics) identified an independent association between SUA and combined CBV events in the whole database (HR 1.249, 95% confidence interval, 1.041-1.497, p?=?0.016). The results of the present study confirm that SUA is an independent risk marker for CBV events after adjusting for potential confounding variables, including arterial hypertension, and demonstrate that >4.79?mg/dL is a valid prognostic cut-off value.

  Abstract
  
  INTRODUCTION:
  Cardiac rehabilitation (CR) is an effective tool for secondary prevention after acute coronary syndrome (ACS).
  
  AIM:
  Aim of our study was to find the significant determinants of exercise capacity (evaluated with the six-minute walking test-6-MWT) and functional improvement in patients undergoing CR after an ACS.
  
  METHODS:
  The study group included 298 patients (mean age 61.6 ± 10.2 years; males 80.2%) who, after ACS, were enrolled in CR program at Niguarda Hospital in Milan from 2015 to 2018. For all patients, we collected anamnestic, clinical and instrumental cardiological data. All patients performed a 6-MWT at the beginning (6-MWT-1) and at the end (6-MWT-2) of CR program. ? meters were used to represent functional improvement.
  
  RESULTS:
  Multiple linear regression models were carried out for 6-MWT-1, 6-MWT-2, ? meters and % ? meters. Standardized regression coefficients showed that age (? = - 0.237; p
  CONCLUSIONS:
  Our data showed that functional improvement after CR in ACS patients is mainly related to non-cardiological variables. Instead it is related to intrinsic factors, both modifiable (BMI) and non-modifiable (age, sex).

  Abstract
  
  AIMS:
  To evaluate endothelial function in subjects with left ventricular assist devices (LVADs), comparing them with subjects with chronic heart failure with reduced ejection fraction on the list for heart transplant (HT) and with HT patients with a normal systolic cardiac function to identify any differences.
  
  METHODS:
  We enrolled 28 subjects with LVAD, 55 subjects with HT, and 42 subjects with heart failure on the transplant list. The subjects underwent a general physical examination, assessment of laboratory blood parameters, and assessment of endothelial function through flow-mediated dilation (FMD) of brachial artery.
  
  RESULTS:
  The three groups were homogeneous as regards age, gender, smoke abuse, C-reactive protein (CRP) and FMD parameters (P = ns). In LVAD group percentage of FMD change showed an inverse correlation with CRP (rho: -0.5, P: 0.003), a well-known marker of inflammation and tissue damage.
  
  CONCLUSIONS:
  Continuous flow related to LVAD seems to not worsen endothelial function. Endothelial function was not affected by cardiovascular risk factors (hypertension, hypercholesterolaemia, diabetes, obesity, and tobacco habit), by the functional status expressed by New York Heart Association class, by the left ventricular systolic function and by the presence or absence of ischaemic heart disease in all the populations analysed. CRP was the only factor able to influence percentage of FMD change in patient with LVAD, reinforcing the hypothesis that inflammation is the main determinant of endothelial function.

  Abstract
  
  SARS-CoV-2 infection determines a disease that predominantly affects lungs. However the cytokines storms, determined by the huge immune response to the infection, could affect also other organs and apparatus such as heart and vessels. Beyond the acute inflammation itself also hypercoagulative status has been linked to SARSCoV-2 infection and this surely relates to the increase seen in prevalence of pulmonary embolism and myocardial infarction. A number of cardiac abnormalities and pathologies have been observed, with special attention to cardiac arrhythmias and myocardial involvement. Furthermore, indirect damages determined by the reduction in acute and chronic cardiovascular care, results in a strong mortality and morbidity outcomes in cardiological patients. In this review we will summarise current knowledge on both direct and indirect cardiovascular damages determined by the SARS-CoV-2 pandemia.

  Abstract
  
  BACKGROUND AND AIMS:
  Uric Acid (UA) has been related to the development of Cardio-Vascular (CV) events in patients affected by Chronic Coronary Syndromes (CCS). Among various hypothesis, two arise: UA may negatively act on coronary artery determining a higher degree of atherosclerotic disease, and/or on heart determining a higher prevalence of diastolic dysfunction. Both the above hypothesized effects are object of our investigation.
  
  METHODS AND RESULTS:
  231 patients who were admitted to the cardiological department of the Niguarda Hospital (Milan, Italy) for CCS from January 2017 to June 2018 were enrolled. Coronary atherosclerotic burden was evaluated from coronary angiography as the number and type of involved vessels, as well as with both Gensini and Syntax scores. All subjects underwent a complete echocardiogram. At unadjusted and adjusted/multivariable analysis, UA levels were not significantly associated with variables analysed from the coronary angiography (number and type of vessels involved, neither the Gensini and Syntax scores) as well as with echocardiographic parameters regarding systolic and diastolic function.
  
  CONCLUSIONS:
  In conclusion, the main finding of our work is the absence of a role for UA in determining coronary arteries disease as well as LV diastolic dysfunction in CCS subjects. Taking together the results of previous studies with ours, we hypothesize that UA could act on heart (both on coronary arteries and on LV function) in an early phase of the disease, whereas while in the advanced stages other factors (previous myocardial infarction, previous myocardial revascularization and so on) may overshadow its effects.

  Abstract
  
  INTRODUCTION:
  Atherosclerosis causes a chronic reduction of vascularization with consequent impairment of the performance of organs, like the brain or muscles, which determines the functional and cognitive decline of the elderly and their ability to respond to acute stressful condition. Therefore, our aim was to evaluate if ankle brachial index (ABI) could effectively be a determinant of in-hospital functional status and complications in elderly hospitalized patients.
  
  METHODS:
  This is a monocentric cross-sectional study of 189 patients aged 65 years or older. The study was undertaken at the Internal Medicine ward of Niguarda Hospital in Milan. ABI (BOSO ABY-System 100) and in-hospital status (activities of daily living, ADL and instrumental activities of daily living, IADL) were collected on the second day of hospitalization. Complications (falls and delirium episodes) were also recorded during the whole hospitalization period.
  
  RESULTS:
  The average age of patients was 79.3 ± 6.9 years. Among outcomes, only ADL (r = 0.192, p = 0.007) and IADL score (r = 0.200, p = 0.005) showed significant correlation with ABI. Moreover, during the subsequent logistic regression, ABI remained among the statistically significant determinants of both scores (? = 0.231, p = 0.013 and ? = 0.314, p = 0.001, respectively).
  
  CONCLUSIONS:
  The main result of our study is the finding of ABI as a significant determinant of acute in-hospital functional impairment (evaluated as ADL and IADL scores). The continuous exposure of the brain and muscles to the reduced perfusions induced by vascular atherosclerosis, probably determined the reduced ability to respond to stressful conditions.

  Abstract
  
  BACKGROUND:
  Hyperuricemia is commonly observed in patients with chronic kidney disease (CKD). However, a better understanding of the relationship among uric acid (UA) values, glomerular filtration rate (GFR) and albuminuria may shed light on the mechanisms underlying the excess of cardiovascular mortality associated with both chronic kidney disease and hyperuricemia and lead to better risk stratification. Our main goal was to study the relationships between serum uric acid and kidney disease measures (namely estimated GFR [eGFR] and albuminuria) in a large cohort of individuals at cardiovascular risk from the URic acid Right for heArt Health (URRAH) Project database.
  
  METHODS:
  Clinical data of 26,971 individuals were analyzed. Factors associated with the presence of hyperuricemia defined on the basis of previously determined URRAH cutoffs for cardiovascular and all-cause mortality were evaluated through multivariate analysis. Chronic kidney disease was defined as eGFR?60 ml/min per 1.73 m and/or abnormal urinary albumin excretion diagnosed as: (i) microalbuminuria if urinary albumin concentration was?>?30 and???300 mg/L, or if urinary albumin-to-creatinine ratio (ACR) was?>?3.4 mg/mmol and???34 mg/mmol; (ii) macroalbuminuria if urinary albumin concentration was?>?300 mg/L, or if ACR was?>?34 mg/mmol.
  
  RESULTS:
  Mean age was 58?±?15 years (51% males, 62% with hypertension and 12% with diabetes), mean eGFR was 81 ml/min per 1.73m2with a prevalence of eGFR?60 and micro- or macroalbuminuria of 16, 15 and 4%, respectively. Serum uric acid showed a trend towards higher values along with decreasing renal function. Both the prevalence of gout and the frequency of allopurinol use increased significantly with the reduction of eGFR and the increase in albuminuria. Hyperuricemia was independently related to male gender, eGFR strata, and signs of insulin resistance such as body mass index (BMI) and triglycerides.
  
  CONCLUSIONS:
  The lower the eGFR the higher the prevalence of hyperuricemia and gout. In subjects with eGFR?60 ml/min the occurrence of hyperuricemia is about 10 times higher than in those with eGFR?>?90 ml/min. The percentage of individuals treated with allopurinol was below 2% when GFR was above 60 ml/min, it increased to 20% in the presence of CKD 3b and rose further to 35% in individuals with macroalbuminuria.

  Abstract
  
  Cardiovascular disease is one of the most common causes of hospitalization and is associated with high morbidity and mortality rates. Among the most important modifiable and well-known risk factors are an unhealthy diet and sedentary lifestyle. Nevertheless, adherence to healthy lifestyle regimes is poor. The present study examined longitudinal trajectories (pre-event, 6-, 12-, 24-, 36-, and 60-month follow-ups) of protein intake (fish, legumes, red/processed meat) and physical activity in 275 newly-diagnosed patients with acute coronary syndrome. Hierarchical Generalized Linear Models were performed, controlling for demographic and clinical variables, the season in which each assessment was made, and the presence of anxiety and depressive symptoms. Significant changes in protein intake and physical activity were found from pre-event to the six-month follow-up, suggesting the adoption of healthier behaviors. However, soon after the six-month follow-up, patients experienced significant declines in their healthy behaviors. Both physical activity and red/processed meat intake were modulated by the season in which the assessments took place and by anxiety symptoms over time. The negative long-term trajectory of healthy behaviors suggests that tailored interventions are needed that sustain patients' capabilities to self-regulate their behaviors over time and consider patient preference in function of season.

  Abstract
  
  INTRODUCTION:
  Serum uric acid (SUA) has been depicted as a contributory causal factor in metabolic syndrome (MS), which in turn, portends unfavourable prognosis.
  
  AIM:
  We assessed the prognostic role of SUA in patients with and without MS.
  
  METHODS:
  We used data from the multicentre Uric Acid Right for Heart Health study and considered cardiovascular mortality (CVM) as death due to fatal myocardial infarction, stroke, sudden cardiac death, or heart failure.
  
  RESULTS:
  A total of 9589 subjects (median age 58.5 years, 45% males) were included in the analysis, and 5100 (53%) patients had a final diagnosis of MS. After a median follow-up of 142 months, we observed 558 events. Using a previously validated cardiovascular SUA cut-off to predict CVM (>?5.1 mg/dL in women and 5.6 mg/dL in men), elevated SUA levels were significantly associated to a worse outcome in patients with and without MS (all p?0.0001) and provided a significant net reclassification improvement of 7.1% over the diagnosis of MS for CVM (p?=?0.004). Cox regression analyses identified an independent association between SUA and CVM (Hazard Ratio: 1.79 [95% CI, 1.15-2.79]; p?0.0001) after the adjustment for MS, its single components and renal function. Three specific combinations of the MS components were associated with higher CVM when increasing SUA levels were reported, and systemic hypertension was the only individual component ever-present (all p?0.0001).
  
  CONCLUSION:
  Increasing SUA levels are associated with a higher CVM risk irrespective of the presence of MS: a cardiovascular SUA threshold may improve risk stratification.

  Abstract
  
  AIMS :
  Whether the association between uric acid (UA) and cardiovascular disease is influenced by some facilitating factors is unclear. The aim of this study was to investigate whether the risk of cardiovascular mortality (CVM) associated with elevated UA was modulated by the level of resting heart rate (HR).
  
  METHODS AND RESULTS :
  Multivariable Cox analyses were made in 19 128 participants from the multicentre Uric acid Right for heArt Health study. During a median follow-up of 11.2?years, there were 1381 cases of CVM. In multivariable Cox models both UA and HR, either considered as continuous or categorical variables were independent predictors of CVM both improving risk discrimination (P???0.003) and reclassification (P?0.0001) over a multivariable model. However, the risk of CVM related to high UA (?5.5?mg/dL, top tertile) was much lower in the subjects with HR
  CONCLUSION :
  This data suggest that the contribution of UA to determining CVM is modulated by the level of HR supporting the hypothesis that activation of the sympathetic nervous system facilitates the action of UA as a cardiovascular risk factor.

  Abstract
  
  Most respiratory viruses show pronounced seasonality, but for SARS-CoV-2, this still needs to be documented. We examined the disease progression of COVID-19 in 6,914 patients admitted to hospitals in Europe and China. In addition, we evaluated progress of disease symptoms in 37,187 individuals reporting symptoms into the COVID Symptom Study application. Meta-analysis of the mortality risk in seven European hospitals estimated odds ratios per 1-day increase in the admission date to be 0.981 (0.973-0.988,

  Abstract
  
  BACKGROUND AND AIMS:
  Metabolic Syndrome (MS) has been related to an impairment in arterial structural and functional properties with heterogeneous results. In this paper we focused on the effects of MS on arterial carotid-femoral PWV and common carotid IMT in two different populations, one of hypertensive patients and one of healthy controls.
  
  METHODS AND RESULTS:
  We enrolled 816 consecutive HT and 536 healthy controls. Vascular structural (IMT) and functional (PWV) properties were evaluated. NCEP-ATP-III criteria were used for diagnosis of MS. MS was diagnosed in 26.9% and 6.9% in hypertensive and control subjects, respectively. PWV was similar in controls with and without MS (7.7 ± 1.9 vs 7.6 ± 1.1 m/s, p = 0.69), while IMT was higher in controls with than those without MS (0.64 ± 0.18 vs 0.57 ± 0.13 mm, p = 0.02). Hypertensives with MS were older (57.9 ± 12.2 vs 52.7 ± 14.1 years, p 
  CONCLUSIONS:
  the main finding of our work is that MS is a significant determinant of IMT while this is not the case for PWV. This result have been confirmed both in hypertensive subjects and in healthy controls.

  Abstract
  
  OBJECTIVE:
  Although the relationship between hyperuricemia and cardiovascular events has been extensively examined, data on the role of diuretic-related hyperuricemia are still scanty. The present study was designed to collect information on the relationship between diuretic-related hyperuricemia and cardiovascular events.
  
  METHODS:
  The URic acid Right for heArt Health (URRAH) study is a nationwide, multicentre, observational cohort study involving data on individuals recruited from all the Italy territory under the patronage of the Italian Society of Hypertension with an average follow-up period of 122.3?±?66.9 months. Patients were classified into four groups according to the diuretic use (yes vs. no) and serum uric acid (SUA) levels (higher vs. lower than the median value of 4.8?mg/dl). All-cause death, cardiovascular deaths and first cardiovascular event were considered as outcomes.
  
  RESULTS:
  Seventeen thousand, seven hundred and forty-seven individuals were included in the analysis. Mean age was 57.1?±?15.2 years, men were 45.3% and SBP and DBP amounted to 144.1?±?24.6 and 85.2?±?13.2?mmHg. 17.2% of individuals take diuretics of whom 58% had SUA higher than median value. Patients with hyperuricemia without diuretic use served as reference group. In multivariate adjusted analysis (sex, age, SBP, BMI, glucose, total cholesterol, and glomerular filtration rate) individuals with hyperuricemia and diuretic use exhibit a similar risk for the three outcomes as compared with the reference group.
  
  CONCLUSION:
  Our study showed that diuretic-related hyperuricemia carry a similar risk of cardiovascular events and all-cause mortality when compared with individuals that present hyperuricemia in absence of diuretic therapy.

  Abstract
  
  BACKGROUND AND AIMS:
  Ankle brachial index (ABI) is a simple and cheap parameter to assess the presence of atherosclerosis. It could also help correctly reclassify the cardiovascular risk when added to the Framingham risk score (FRS). Recent evidence has demonstrated improvement in prediction performance of ABI when added to FRS, particularly in women. However, no studies have been published yet evaluating the cost-effectiveness of this approach. This study attempts to fill in this gap by assessing the cost-effectiveness of ABI measurements in primary prevention in women.
  
  METHODS:
  We developed a Markov model to compare two different strategies for assessing the cardiovascular risk (low, intermediate and high) among women in the general population: 1) FRS strategy, and 2) FRS + ABI strategy; and the relative impact associated with interventions for preventing CV events in intermediate and high-risk categories.
  
  RESULTS:
  In the base-case analysis, FRS + ABI reported an additional cost of ? 110 and a gain of 0.0039 QALYs per patient, resulting in an ICER of ? 27.986/QALY, when compared to FRS alone. The ICER improved to ?1.641/QALY when using a lifetime horizon. The effectiveness of preventive CV disease interventions reported also a significant impact. A 32% reduction of CV events was the minimum value estimated to maintain FRS + ABI as a cost-effective strategy.
  
  CONCLUSIONS:
  The addition of ABI to FRS is a cost-effective approach in women classified at low and intermediate risk with FRS only. This new approach gives the possibility to reclassify and allocate them into the appropriate risk group and treatment.

  Abstract
  
  BACKGROUND AND AIM:
  Heterogeneous results have been obtained in the relationship between Uric Acid (UA) and Target Organ Damage (TOD). In the present study we sought to assess the prevalence of hyperuricemia in healthy subjects as well as the role of UA in determining TOD. We evaluated vascular, cardiac and renal TODs in the whole population as well as sub-grouped by gender.
  
  METHODS AND RESULTS:
  As many as 379 blood donors participated at the present analysis. TOD was evaluated as Pulse Wave Velocity (PWV), Left Ventricular Mass Index (LVMI) and carotid Intima-Media Thickness (IMT). Hyperuricemia was defined with the classic cut-off (>7.0 in men and >6.0 mg/dL in women) but also with a most recently defined one (5.6 mg/dL for both sex). Hyperuricemia was present in 6.3% of the whole population (7.3% males, 2.8% females) considering the classic cut-off, while, with the recently identified one, it was present in 28.2% of the whole population (37.3% males, 4.7% females). Despite all the evaluated TODs significantly correlated with UA, linear multivariate regression analysis showed that none of them, except for GFR, displayed UA as a significant covariate. Similar figures were found also when both correlation and linear regression analyses were repeated in the two genders separately.
  
  CONCLUSIONS:
  Hyperuricemia is an important problem also in healthy subjects and its prevalence could further increase if lower cut-off will be used. In this specific population UA is significantly associated with renal impairment while this was not the case for cardiac and vascular damage.

  Abstract
  
  BACKGROUND:
  To assess the association between admission serum uric acid (SUA) levels and in-hospital outcomes in a real-world patients population with acute coronary syndrome (ACS) and to investigate the potential incremental prognostic value of SUA added to GRACE score (GRACE-SUA score).
  
  METHODS:
  The data of consecutive ACS patients admitted to Coronary Care Unit of San Paolo and Niguarda hospitals in Milan (Italy) were retrospectively analyzed.
  
  RESULTS:
  1088 patients (24% female) were enrolled. Mean age was 68 years (IQR 60-78). STEMI and NSTE-ACS patients were 504 (46%) and 584 (54%) respectively. SUA (OR 1.72 95%CI 1.33-2.22, p 
  CONCLUSIONS:
  High admission levels of SUA are independently associated with in-hospital adverse outcomes and mortality in a contemporary population of ACS patients. The inclusion of SUA to GRACE risk score seems to lead to a more accurate prediction of in-hospital mortality in this study population.

  Abstract
  
  OBJECTIVE:
  To assess the prognostic cut-off values of serum uric acid (SUA) in predicting fatal and morbid heart failure in a large Italian cohort in the frame of the Working Group on Uric Acid and Cardiovascular Risk of the Italian Society of Hypertension.
  
  METHODS:
  The URic acid Right for heArt Health (URRAH) study is a nationwide, multicentre, cohort study involving data on individuals aged 18-95 years, recruited on a community basis from all regions of Italy under the patronage of the Italian Society of Hypertension with a mean follow-up period of 128?±?65 months. Incident heart failure was defined on the basis of International Classification of Diseases Tenth Revision codes and double-checked with general practitioners and hospital files. Multivariate Cox regression models having fatal and morbid heart failure as dependent variables, adjusted for sex, age, SBP, diabetes, estimated glomerular filtration rate, smoking habit, ethanol intake, BMI, haematocrit, LDL cholesterol, previous diagnosis of heart failure and use of diuretics as possible confounders, were used to search for an association between SUA as a continuous variable and heart failure. By means of receiver operating characteristic curves, two prognostic cut-off values (one for all heart failure and one for fatal heart failure) were identified as able to discriminate between individuals doomed to develop the event. These cut-off values were used as independent predictors to divide individuals according to prognostic cut-off values in a multivariate Cox models, adjusted for confounders.
  
  RESULTS:
  A total of 21?386 individuals were included in the analysis. In Cox analyses, SUA as a continuous variable was a significant predictor of all [hazard ratio 1.29 (1.23-1.359), P?0.0001] and fatal [hazard ratio 1.268 (1.121-1.35), P?0.0001] incident heart failure. Cut-off values of SUA able to discriminate all and fatal heart failure status were identified by mean of receiver operating characteristic curves in the whole database: SUA more than 5.34?mg/dl (confidence interval 4.37-5.6, sensitivity 52.32, specificity 63.96, P?0.0001) was the univariate prognostic cut-off value for all heart failure, whereas SUA more than 4.89?mg/dl (confidence interval 4.78-5.78, sensitivity 68.29, specificity 49.11, P?0.0001) for fatal heart failure. The cut-off for all heart failure and the cut-off value for fatal heart failure were accepted as independent predictors in the Cox analysis models, the hazard ratios being 1.645 (1.284-2.109, P?0.0001) for all heart failure and 1.645 (1.284-2.109, P?0.0001) for fatal heart failure, respectively.
  
  CONCLUSION:
  The results of the current study confirm that SUA is an independent risk factor for all heart failure and fatal heart failure, after adjusting for potential confounding variables and demonstrate that a prognostic cut-off value can be identified for all heart failure (>5.34?mg/dl) and for fatal heart failure (>4.89?mg/dl).

  Abstract
  
  BACKGROUND AND PURPOSE:
  Radiation Induced Heart Disease (RIHD) represents a late effect of chest irradiation, contributing in increasing mortality rate in oncological patients by affecting pericardium, myocardium, valvs and coronaries. Currently, regarding the risk of Coronary Artery Disease (CAD), a cardiological screening involving exercise stress electrocardiography after 5-10 years from radiotherapy is advised. We sought to determine the rate of ischemia at exercise stress electrocardiography in a population of patients without cardiovascular risk factors who sustained radiotherapy, using a cohort of patients presenting with at least one cardiovascular risk factor as control group.
  
  DESIGN AND METHODS:
  A population of 115 patients who sustained chest irradiation (and associated chemotherapy), presenting without classic cardiovascular risk factors or typical symptoms suggesting CAD, was evaluated with exercise stress electrocardiography. 135 patients with at least one risk factor for cardiovascular disease candidate to stress testing for primary prevention or for atypical symptoms served as control group.
  
  RESULTS:
  The cohort of irradiated patients without classical cardiovascular risk factors is younger (48.7 ± 10.1 vs 60.5 ± 10.8 years, p 
  CONCLUSIONS:
  Chest irradiation represents a strong cardiovascular risk factor. In fact, prevalence of positive ECG-stress test is not different (nor higher and nor lower) in irradiated subjects without cardiovascular risk and not irradiated patients with classic cardiovascular risk.

  Abstract
  
  INTRODUCTION:
  Cardiac rehabilitation (CR) improves the functional capacity and the prognosis of patients with coronary artery disease.
  
  AIM:
  Our study was aimed at assessing the relationship between functional improvement (evaluated with 6-min Walk Test-6MWT) and the improvement in left ventricular ejection fraction (LVEF) after CR.
  
  METHODS:
  We collected data from 249 patients (age 66.79?±?11.06 years; males 81.52%) with a recent history of Acute Coronary Syndrome that performed CR. The functional improvement after CR was expressed as the ? between distance covered at the final versus the initial 6-min Walking Test (6-MWT), while LVEF was calculated with transthoracic echocardiogram at the beginning and at the end of the CR.
  
  RESULTS:
  Patients were divided accordingly to their pre-rehab LVEF (??55% vs?55%). With superimposable age and baseline 6MWT distance covered (434.58 vs 405.12 m, p?=?0.08), the latter group presented higher ? meter values at 6MWT (167.93 vs 193.97 m, p?=?0.018). However, no statistically significant positive correlation between ? meters and ? LVEF was found. Moreover, linear regression analyses found that nor baseline LVEF nor ? LVEF were significant determinants of ? meters when considering the whole group, with age, basal 6MWT and peak CK-MB as additional covariates in the model.
  
  CONCLUSION:
  Although it could be expected that an increase in LVEF is related to the functional improvement after CR, no significant correlation was found in our population.

  Abstract
  
  BACKGROUND:
  This study explored both the evolution of the information needs and the perceived relevance of different health information sources in patients with essential hypertension. It also investigated the relationships between information needs and the perceived relevance of information sources with socio-demographic and clinical variables.
  
  METHODS:
  Two hundred and two patients with essential arterial hypertension were enrolled in the study and evaluated at baseline and during three follow-ups at 6, 12 and 24?months after baseline. Patients had a mean age of 54.3?years [range 21-78; SD?=?10.4], and 43% were women. Repeated measures ANOVA, Bonferroni post hoc tests, and Cochran's Q Test were performed to test differences in variables of interest over time.
  
  RESULTS:
  It was observed a significant reduction in all the domains of information needs related to disease management except for pharmacological treatment and risks and complications. At baseline, patients reported receiving health information primarily from specialists, general practitioners, relatives, and television, but the use of these sources decreased over time, even if the decrease was significant only for relatives. Multiple patterns of relationships were found between information needs and the perceived relevance of sources of information and socio-demographics and clinical variables, both at baseline and over time.
  
  CONCLUSIONS:
  The findings showed a general decrease in both the desire for information and the perceived relevance of different information sources. Hypertensive patients appeared to show little interest in health communication topics as their disease progressed. Understanding patients' information needs and the perceived relevance of different information sources is the first step in implementing tailored communication strategies that can promote patients' self-management skills and optimal clinical outcomes.

  Abstract
  
  The latest European Guidelines of Arterial Hypertension have officially introduced uric acid evaluation among the cardiovascular risk factors that should be evaluated in order to stratify patient's risk. In fact, it has been extensively evaluated and demonstrated to be an independent predictor not only of all-cause and cardiovascular mortality, but also of myocardial infraction, stroke and heart failure. Despite the large number of studies on this topic, an important open question that still need to be answered is the identification of a cardiovascular uric acid cut-off value. The actual hyperuricemia cut-off (>?6 mg/dL in women and 7 mg/dL in men) is principally based on the saturation point of uric acid but previous evidence suggests that the negative impact of cardiovascular system could occur also at lower levels. In this context, the Working Group on uric acid and CV risk of the Italian Society of Hypertension has designed the Uric acid Right for heArt Health project. The primary objective of this project is to define the level of uricemia above which the independent risk of CV disease may increase in a significantly manner. In this review we will summarize the first results obtained and describe the further planned analysis.

  Abstract
  
  The association between serum uric acid (SUA) and pulse wave velocity (PWV), has been extensively evaluated but with some discrepancies in results. A further limitation refers to the fact that only few data were analyzed taking into account the possible effects of gender. The purpose of this study was to estimate the association between SUA and arterial stiffness in general population and hypertensive patients, as a whole population and as divided by gender, by pooling results from existing studies. Carotid-femoral and brachial-ankle PWV (cf- and ba-PWV) have been analyzed separately and subgroup analyses by gender are reported. Among 692 potentially relevant works, 24 articles were analyzed. Seven studies referred to cf-PWV in the general population with an overall positive association at adjusted analysis for both males and females (beta regression coefficient (ß): 0.07; 95%CI: 0.03; 0.11 and ß: 0.06; 95%CI: 0.03; 0.09, respectively). Twelve studies referred to ba-PWV in the general population with the finding of a positive association at adjusted analysis for females (ß: 0.04; 95% confidence interval (CI): 0.01;0.07), but not for males (ß: 0.13; 95%CI: -0.09; 0.34). In hypertensive patients only four studies evaluated cf-PWV and one ba-PWV with only one study (with cf-PWV) finding positive association. The association between SUA and cf-PWV resulted significant in general population in both males and females while it was only significant for female regarding ba-PWV. Furthermore, the few available studies found no significant relationship between SUA and both cf- and ba-PWV in hypertensive subjects.

  Abstract
  
  Serum uric acid (SUA) levels discriminating across the different strata of cardiovascular risk is still unknown. By utilizing a large population-based database, we assessed the threshold of SUA that increases the risk of total mortality and cardiovascular mortality (CVM). The URRAH study (Uric Acid Right for Heart Health) is a multicentre retrospective, observational study, which collected data from several large population-based longitudinal studies in Italy and subjects recruited in the hypertension clinics of the Italian Society of Hypertension. Total mortality was defined as mortality for any cause, CVM as death due to fatal myocardial infarction, stroke, sudden cardiac death, or heart failure. A total of 22 714 subjects were included in the analysis. Multivariate Cox regression analyses identified an independent association between SUA and total mortality (hazard ratio, 1.53 [95% CI, 1.21-1.93]) or CVM (hazard ratio, 2.08 [95% CI, 1.146-2.97];

  Abstract
  
  OBJECTIVE:
  The Working Group on Uric Acid and Cardiovascular Risk of the Italian Society of Hypertension conceived and designed an ad-hoc study aimed at searching for prognostic cut-off values of serum uric acid (SUA) in predicting fatal myocardial infaction (MI) in women and men.
  
  METHODS:
  The URic acid Right for heArt Health study is a nationwide, multicentre, observational cohort study involving data on individuals aged 18-95 years recruited on a regional community basis from all the territory of Italy under the patronage of the Italian Society of Hypertension with a mean follow-up period of 122.3?±?66.9 months.
  
  RESULTS:
  A total of 23?467 individuals were included in the analysis. Cut-off values of SUA able to discriminate MI status were identified by mean of receiver operating characteristic curves in the whole database (>5.70?mg/dl), in women (>5.26?mg/dl) and in men (>5.49?mg/dl). Multivariate Cox regression analyses adjusted for confounders (age, arterial hypertension, diabetes, chronic kidney disease, smoking habit, ethanol intake, BMI, haematocrit, LDL cholesterol and use of diuretics) identified an independent association between SUA and fatal MI in the whole database (hazard ratio 1.381, 95% confidence intervals, 1.096-1.758, P?=?0.006) and in women (hazard ratio 1.514, confidence intervals 1.105-2.075, P?0.01), but not in men.
  
  CONCLUSION:
  The results of the current study confirm that SUA is an independent risk factor for fatal MI after adjusting for potential confounding variables, and demonstrate that a prognostic cut-off value associated to fatal MI can be identified at least in women.

  Abstract
  
  Accurate measurement of blood pressure (BP) has a pivotal role in the management of patients with arterial hypertension. Recently, introduction of unattended office BP measurement has been proposed as a method allowing more accurate management of hypertensive patients and prediction of hypertension-mediated target organ damage (HMOD). This approach to BP measurement has been in particular proposed to avoid the white coat effect (WCE), which can be easily assessed once both attended and unattended BP measurements are obtained. In spite of its interest, the role of WCE in predicting HMOD remains largely unexplored. To fill this gap the Young Investigator Group of the Italian Hypertension Society (SIIA) conceived the study "Evaluation of unattended automated office, conventional office and ambulatory blood pressure measurements and their correlation with target organ damage in an outpatient population of hypertensives". This is a no-profit multicenter observational study aiming to correlate attended and unattended BP measurements for quantification of WCE and to correlate WCE with markers of HMOD, such us left ventricular hypertrophy, left atrial dilatation, and peripheral atherosclerosis. The Ethical committee of the Federico II University hospital has approved the study.

  Abstract
  
  BACKGROUND:
  Thoracic endovascular aortic repair (TEVAR) currently represents the gold standard of treatment for thoracic aortic injury (TAI). Nevertheless, there is an ongoing debate surrounding its safety and subsequent cardiovascular effects. Our aim is to assess heart and vascular structure and function remodeling after TEVAR in TAI young patients.
  
  METHODS:
  We evaluated 20 patients (18 men, age 41 ± 14 years, 11 treated with Gore CTAG, 9 with Medtronic Valiant) with office and 24-hr blood pressure (BP) with specific vascular stiffness analysis (Mobil-O-Graph), aortic diameters (computed tomography scan) and left ventricular mass index (LVMI echocardiogram). Evaluation was done after a median time of 5.0 ± 3.5 years from the trauma.
  
  RESULTS:
  After TAI 12 patients (55%) developed hypertension. When patients were divided according to treating time, those treated for more than 3 years show higher LVMI, PWV, and ascending aorta dilatation.
  
  CONCLUSIONS:
  Our study shows that TEVAR for TAI is associated with heart and vascular remodeling. The presence of TEVAR modifies aortic functional properties and could induce an increase in BP that can promote aortic and cardiac damage, even in young patients.

  Abstract
  
  Treatment of overt form of hypertrophic cardiomyopathy (HCM) is often unsuccessful. Efforts are focused on a possible early identification in order to prevent or delaying the development of hypertrophy. Our aim was to find an echocardiographic marker able to distinguish mutation carriers without left ventricular hypertrophy (LVH) from healthy subjects. We evaluated 28 patients, members of eight families. Three types of mutation were recognized: MYBPC3 (five families), MYH7 (two families) and TNNT2 (one family). According to genetic (G) and phenotypic (Ph) features, patients were divided in three groups: Group A (10 patients), mutation carriers with LVH (G+/Ph+); Group B (9 patients), mutation carriers without LVH (G+/Ph-); Group C (9 patients), healthy subjects (G-/Ph-). Echocardiography examination was performed acquiring standard 2D, DTI and 2D-strain imaging. Global longitudinal strain (GLS) and global radial strain (GRS) at basal and mid-level were measured. GRS was significantly different between group B and C at basal level (32.18%?±?9.6 vs. 44.59%?±?12.67 respectively; p-value?0.0001). In basal posterior and basal inferior segments this difference was particularly evident. ROC curves showed for both the involved segments good AUCs (0.931 and 0.861 for basal posterior and inferior GRS respectively) with the best predictive cut-off for basal posterior GRS at 43.65%, while it was 38.4% for basal inferior GRS. Conversely, GLS values were similar in the three group. 2D longitudinal strain is a valid technique to study HCM. Radial strain and particularly basal posterior and inferior segmental reduction could be able to identify mutation carriers in a pre-clinical phase of disease.

  Abstract
  
  The role of uric acid (UA) on the arterial stiffness progression has been evaluated only in three studies. Our aim was to evaluate its role as a possible determinant of the pulse wave velocity (PWV) progression over a 3.7 ± 0.5 years follow-up period in hypertensive patients. Specific sex analysis was done due to the well-known sex interaction with UA levels. We enrolled 422 consecutive hypertensive outpatients. At baseline anamnestic, blood pressure (BP) and laboratory data as well as PWV were assessed. PWV was performed again at follow-up examination. Hyperuricemia was defined as a UA > 6 mg/dL for women and > 7 mg/dL for men. Baseline age was 53.2 ± 13 years, 58% were males, systolic and diastolic BP (SBP/DBP) 141.7 ± 17.7/86.8 ± 10.8 mm Hg, UA 5.2 ± 1.4 mg/dL, and PWV 8.5 ± 1.9 m/s. At follow-up, despite better BP values (-8.5 ± 24.6 for SBP and -7.5 ± 15.4 for DBP), PWV increases to 9.1 ± 2.3 m/s (P

  Abstract
  
  Structural and functional arterial properties commonly impair with aging process. These effects on vasculature could act at many levels from microcirculation to large vessels. Above normal aging process classic cardio-vascular risk factors (hypertension, diabetes mellitus, dyslipidemia, etc.) accelerate the physiological process leading to premature structural and functional alterations that has also been termed early vascular aging. Target organ damage evaluation could be clinically important since these alterations precede by many years' cardiovascular events and so their assessment can predict the onset of more serious and costly events giving the opportunity to prevent CV events by earlier therapeutic intervention. This review will focus on large artery functional properties and particularly on the role of inflammation on the aortic stiffening process.

  Abstract
  
  BACKGROUND:
  Vascular structural (intima-media thickness) and functional (carotid pulse wave velocity, cPWV) alterations are related to different patterns of left ventricular (LV) geometry in general population samples and in hypertensive patients. The relationship between vascular damage, evaluated by both echotracking ultrasound and coronary angiography, and LV geometry has not been prospectively analyzed.
  
  METHODS:
  In eight Italian centers, 399 consecutive patients, without history of prior coronary artery disease and with clinical indication to coronary angiography, prospectively underwent cardiac standard ultrasound examination for the evaluation of LV mass, indexed by height to 2.7 power (LVMi?g/m) and relative wall thickness (RWT), the measurement of Doppler flow in the left anterior descending artery (LAD) and the echocardiographic calcium score (eCS). In all patients measurement of common carotid intima-media thickness (cIMT) and cPWV by carotid ultrasound, with the realtime echotracking system was performed. The noninvasive evaluations were performed blindly to clinical information, before coronary angiography.
  
  RESULTS:
  cIMT and cPWV were higher in patients with concentric LV hypertrophy (LVH) (LVMi???49?g/m in men and ?47?g/m in women and RWT???0.42) as compared with those with normal LVMi and geometry (N: LVMi?49?g/m in men and 50%) was greater in patients with concentric LVH and concentric remodeling, as compared with N. Patients with both concentric LVH and concentric remodeling showed higher values of cIMT and cPWV and distal LAD velocity and a greater prevalence of coronary stenosis (>50%) than patients with RWT less than 0.42.
  
  CONCLUSION:
  Our results further reinforced the observation that in patients undergoing elective coronary angiography, concentric geometry is associated with structural and functional carotid alterations, with higher distal LAD flow velocity and eCS. In this large group of patients, concentric geometry is associated with a greater prevalence of coronary stenosis, as assessed by coronary angiography. These results might contribute to explain the greater cardiovascular risk associated with concentric remodeling and LVH.

  Abstract
  
  : Mycotic coronary aneurysm is a rare infective disease of arterial vessel walls. Their development could be linked to the presence of an infective endocarditis or could represent a primary infection at the site of an implanted intracoronary stent. Bacterial agents, particularly Staphylococcus aureus, are the most common etiological agents. Due to an aspecific clinical presentation and examination, diagnosis could be challenging. Multiple imaging techniques (both invasive and noninvasive) are often required to reach the final diagnosis. Prognosis is characterized by high morbidity and mortality rates and, in fact, a tempestive treatment is required, although, to date, scanty data concerning the optimal treatment choice are present in literature.

  Abstract
  
  OBJECTIVE:
  Hyperuricemia has been associated with high blood pressure (BP) values, diabetes mellitus, metabolic syndrome and chronic kidney disease (CKD). In the present study, we assessed the gender-related relationships between serum uric acid (SUA) and cardionephrometabolic variables in central and east European hypertensive patients.
  
  METHODS:
  A total of 3206 treated hypertensive patients with available SUA levels from the BP-CARE study was analyzed. Correlations among SUA, BP values, BP control, diabetes mellitus, metabolic syndrome and CKD were performed according to gender.
  
  RESULTS:
  Twenty-five percent of the whole population showed hyperuricemia (28% in women and 23% in men). These patients were older and showed a greater burden of cardiovascular risk factors (high BP, BMI, glucose, total cholesterol and triglyceridemia). They also showed a greater prevalence of metabolic syndrome, diabetes mellitus, rate of uncontrolled BP, more than high cardiovascular risk and CKD. Prevalence of metabolic syndrome and uncontrolled BP was similar in normouricemic and hyperuricemic women, the latter displaying a higher prevalence of diabetes mellitus, high cardiovascular risk and CKD. Hyperuricemic men were characterized by a greater prevalence of metabolic syndrome, diabetes mellitus, high cardiovascular risk, rate of uncontrolled BP and CKD but not polytherapy. Logistic regression analysis showed that none of the evaluated variables, except CKD, displayed SUA as significant covariate.
  
  CONCLUSION:
  Our findings provide evidence that a high prevalence of hyperuricemia occurs in hypertensive patients from central and east Europe. The data also show that gender-related differences in the association between SUA and cardionephrometabolic variables exist. This is also the case for the relationships between SUA and CKD.

  Abstract
  
  Objectives:
  To evaluate changes in pro-atherosclerotic biomarkers and endothelial function in patients initiating two different PI-based regimens as part of ART.
  
  Design:
  Prospective randomized 24?week study. Treatment-naive HIV-infected patients with CD4+ T cell count >250?cells/mm3 started PI-based regimens including atazanavir/ritonavir (Group A) or lopinavir/ritonavir (Group B) and were followed up in an observational follow-up study until week 96.
  
  Methods:
  The expression of immune activation and adhesion molecules on CD4+ and CD8+ cells and plasma cytokine levels were assessed at weeks 0, 4, 12, 24, 48, 72 and 96. Flow-mediated dilation (FMD), pulse-wave velocity (PWV) and intima-media thickness (IMT) were measured at weeks 0 and 24. Median changes within (signed rank test) and between (Wilcoxon test) arms were calculated.
  
  Results:
  Twenty-seven patients were enrolled, of whom 15 were treated with atazanavir/ritonavir and 12 with lopinavir/ritonavir. After 96?weeks of ART, CD25+/CD8+ T cells and plasma concentration of MCP-1/CCL-2 rose whereas CD44+/CD8+ T cells decreased significantly in both groups. Differences between treatments were noted for HLA-DRII+/CD8+, CD44+/CD4+ and CD11a+/CD4+, with significant increases in Group B versus Group A. No differences between groups regarding IMT, PWV and FMD were found at baseline and week 24.
  
  Conclusions:
  ART initiation with PI-based regimens led to a decrease in pro-atherosclerotic biomarkers at week 24, which then rebounded at week 96. Lopinavir/ritonavir treatment resulted in an unfavourable modulation of such markers compared with atazanavir/ritonavir treatment.

  Abstract
  
  Hypertensive urgencies-emergencies are important and common events. They are defined as a severe elevation in BP, higher than 180/120 mmHg, associated or not with the evidence of new or worsening organ damage for emergencies and urgencies respectively. Anamnestic information, physical examination and instrumental evaluation determine the following management that could need oral (for urgencies) or intravenous (for emergencies) anti-hypertensives drugs. The choice of the specific drugs depend on the underlying causes of the crisis, patient's demographics, cardiovascular risk and comorbidities. For emergencies a maximum BP reduction of 20-25% within the first hour and then to 160/110-100 over next 2-6 h, is considered appropriate with a further gradual decrease over the next 24-48 h to reach normal BP levels. In the case of hypertensive urgencies, a gradual lowering of BP over 24-48 h with an oral medication is the best approach and an aggressive BP lowering should be avoided. Subsequent management with particular attention on chronic BP values control is important as the right treatment of the acute phase.

  Abstract
  
  PURPOSE:
  Only few studies evaluated biomarkers useful for defining the cardiovascular risk of a subject in a pre-clinical condition (i.e. healthy subjects). In this context we sought to determine the relationships of Plasminogen activator inhibitor type 1 (PAI-1), P-Selectin, Tissue Inhibitors Metalloproteinases type 1 (TIMP-1) and Cystatin-C with subclinical Target Organ Damage (TOD) in normotensive and normoglycemic subjects without known cardiovascular and kidney diseases.
  
  MATERIALS AND METHODS:
  480 blood donors participated at the present analysis. TOD was evaluated as Pulse Wave Velocity (PWV), Left Ventricular Hypertrophy (LVH) and Intima Media Thickness (IMT) and carotid plaque presence) grouped together under carotid TOD.
  
  RESULTS:
  3.1% of the subjects showed a PWV higher than 10?m/sec with those subjects exerting significantly lower values of P-Selectine (0.068?±?0.015 vs 0.08?±?0.036?mg/L, p?=?.014). 8.8% of the subjects showed carotid TOD that was associated with higher Cystatin-C values (0.67?±?0.17 vs 0.63?±?0.14?mg/L, p?=?.045). Finally 23.8% of the subjects showed LVH with no significant differences regarding biomarkers. Despite some significant correlations between biomarkers and TOD, at the multivariate analysis none came out to be as significant predictor of the assessed TOD.
  
  CONCLUSIONS:
  in normotensive and normoglycemic healthy subjects, the evaluated biomarkers of atherosclerotic process didn't show any significant association with cardiac, carotid and vascular TOD while age and BP are its principal predictors.

  Abstract
  
  INTRODUCTION:
  Rheumatoid arthritis (RA) represents a risk of non-fatal and cardiovascular events. The aim of the present study was to evaluate simultaneously left and right atrial and ventricular function, as well as arterial stiffness, in RA patients.
  
  METHODS:
  This cross-sectional study included 55 consecutive RA patients and 55 healthy age and gender-matched controls. Blood pressure and arterial stiffness were assessed in all participants, who also underwent a complete echocardiographic examination.
  
  RESULTS:
  RA patients were treated with steroid therapy (52.7%), methotrexate (66.6%) and biological therapy (54.5%). Disease activity score revealed low average RA activity. Augmentation index was significantly higher in RA patients (32.2 ± 8.6 vs. 28.4 ± 8.9%, P = 0.02). Left atrial volume was also higher among RA patients (23.1 ± 8.2 vs. 20.1 ± 7.1 ml/m, P = 0.04), whereas mitral and tricuspid E/A ratios were significantly lower in RA individuals (0.90 ± 0.24 vs. 1.03 ± 0.35, P = 0.02; 1.07 ± 0.31 vs. 1.27 ± 0.35, P = 0.003, respectively). Tissue Doppler systolic and diastolic velocities were similar between the observed groups. Arterial stiffness index showed significant correlation with disease duration (r = 0.29; P = 0.03). Tissue Doppler-derived transmitral late diastolic velocity (A') showed significant correlation with index of disease activity in the RA patients.
  
  CONCLUSIONS:
  Our results showed that left and right ventricular diastolic function and arterial stiffness were significantly deteriorated in the RA patients comparing with controls. The assessment of left and right ventricular diastolic function, as well as vascular function, should be an essential part of clinical evaluation in the RA patients.

  Abstract
  
  Heterogeneous results have been obtained in the relationship between serum uric acid (SUA) and target organ damage (TOD) in patients with hypertension. Clinic blood pressure, SUA, and cardiac, arterial (carotid and aortic), and renal TOD were assessed in 762 consecutive patients with hypertension. Hyperuricemia was defined as an SUA >7.0 in men and >6.0 mg/dL in women. Men with hyperuricemia compared with those with normal SUA showed lower estimated glomerular filtration rates and E/A ratios and a higher prevalence of carotid plaques. Women with hyperuricemia showed lower estimated glomerular filtration rates and E/A ratios and a higher intima-media thickness. Except for pulse wave velocity, all TODs significantly correlated with SUA. However, at multivariate analysis, only estimated glomerular filtration rate was significantly determined by SUA. Our data provide evidence on the role of SUA in the development of TOD only in the case of renal alteration. It is likely that SUA may indirectly act on the other TODs through the increase in blood pressure and the decrease in glomerular filtration rate.

  Abstract
  
  We investigated the relationship between left ventricular mass and brachial office as well as brachial and central ambulatory systolic blood pressure in 7 European centers. Central systolic pressure was measured with a validated oscillometric device, using a transfer function, and mean/diastolic pressure calibration. M-mode images were obtained by echocardiography, and left ventricular mass was determined by one single reader blinded to blood pressure. We studied 289 participants (137 women) free from antihypertensive drugs (mean age: 50.8 years). Mean office blood pressure was 145/88 mm?Hg and mean brachial and central ambulatory systolic pressures were 127 and 128 mm?Hg, respectively. Mean left ventricular mass was 93.3 kg/m, and 25.6% had left ventricular hypertrophy. The correlation coefficient between left ventricular mass and brachial office, brachial ambulatory, and central ambulatory systolic pressure was 0.29, 0.41, and 0.47, respectively (=0.003 for comparison between brachial office and central ambulatory systolic pressure and 0.32 for comparison between brachial and central ambulatory systolic pressure). The results were consistent for men and women, and young and old participants. The areas under the curve for prediction of left ventricular hypertrophy were 0.618, 0.635, and 0.666 for brachial office, brachial, and central ambulatory systolic pressure, respectively (=0.03 for comparison between brachial and central ambulatory systolic pressure). In younger participants, central ambulatory systolic pressure was superior to both other measurements. Central ambulatory systolic pressure, measured with an oscillometric cuff, shows a strong trend toward a closer association with left ventricular mass and hypertrophy than brachial office/ambulatory systolic pressure.

  Abstract
  
  OBJECTIVE:
  The role of risk factors on the progression of arterial stiffness has not yet been extensively evaluated. The aim of the current longitudinal study was to evaluate the determinants of the PWV progression over a 4 years follow-up period in hypertensive subjects.
  
  MATERIALS AND METHODS:
  We enrolled 333 consecutive hypertensive outpatients 18-80 aged, followed by the Hypertension Unit of St. Gerardo Hospital (Monza, Italy). At baseline anamnestic, clinical, BP, laboratory data and cfPWV were assessed. We performed a PWV follow-up examination with a median time amounting to 3.75?±?0.53 years.
  
  RESULTS:
  At baseline the mean age was 54.5?±?12.6 years, SBP and DBP were 141.3?±?18.6 and 86.4?±?10.4?mmHg and PWV was 8.56?±?1.92 m/s. Despite an improvement in BP control (from 37 to 60%), at follow-up the population showed a PWV increase (?PWV 0.87?±?3.05 m/s). PWV and ?PWV gradually increased in age decades. In patients with uncontrolled BP values at follow-up ?PWV showed a greater increase as compared to patients with controlled BP (1.46?±?3.67 vs 0.62?±?2.61 m/s, p?.05). The independent predictors of ?PWV were age, baseline PWV, baseline SBP/MBP and ?SBP/MBP.
  
  CONCLUSIONS:
  the accelerated arterial aging in treated hypertensive subjects is in large measure explained by age and BP values. PWV changes over time would probably give important information that need further future research studies.

  Abstract
  
  INTRODUCTION:
  Pharmacological inhibition of dipeptidyl-peptidase-4 may represent a promising therapeutic approach for glucose control and vascular protection. No information is available on the effects of saxagliptin (S) on aortic pulse wave velocity, carotid intima-media thickness and flow-mediated dilation (FMD, brachial artery) in diabetes.
  
  AIM:
  We investigated the long-term effects of S, as add-on therapy to metformin, on the above mentioned variables.
  
  METHODS:
  In 16 patients with decompensated diabetes aortic pulse wave velocity, carotid intima-media thickness and FMD, office and 24-h ambulatory blood pressure, anthropometric, biochemical and metabolic parameters were measured at baseline and after 6 and 12 months of treatment. A group of 16 compensated diabetics served as controls.
  
  RESULTS:
  The two groups showed superimposable values of the different parameters, with the exception of glycated hemoglobin, blood glucose significantly (P 
  CONCLUSIONS:
  Thus treatment with S added-on to metformin results in beneficial effects on endothelial function, related at least in part to the concomitant improvement in glucose metabolism. This may represent a first step in the chain of events leading to a reduction in the progression of the vascular atherogenic process.

  Abstract
  
  INTRODUCTION:
  Aortic stenosis (AS) is more than only a degenerative disease, it could be also an atherosclerotic-like process involving the valve instead of the vessels. Little is known about the relation of arterial stiffness and AS.
  
  AIM:
  We sought to determine wether pulse wave velocity (PWV), is related to AS severity and to the procedures response, both as surgical aortic-valve-replacement (AVR) and trascatheter-aortic-valve-implantation (TAVI).
  
  METHODS:
  30 patients with severe AS were treated (15 AVR, 15 TAVI). Before the procedures (t0) and after 1 week (t1) echocardiography and PWV were evaluated.
  
  RESULTS:
  On the whole population, subjects with higher PWV showed higher transvalvular pressure gradient at baseline (mean: 56.5 ± 15.1 vs 45.4 ± 9.5; peak: 93.3 ± 26.4 vs 73.3 ± 14.9, p = 0.02) and, a significantly greater response to the procedures (mean: -42.9 ± 17.2 vs -27.9 ± 10.1, peak: -68.7 ± 29.2 vs -42.8 ± 16.4, p = 0.02). When the two different procedures groups were separated, data were confirmed only in the TAVI subgroup.
  
  CONCLUSIONS:
  In patients undergoing procedures for AS, PWV is correlated with transvalvular gradient and, in TAVI subjects, is able to predict the echocardiographic response. Baseline evaluation of PWV in patients candidates to TAVI can help the selection of subjects, even if larger and longer studies are needed before definitive conclusion can be drawn.

  Maloberti Alessandro, Meani Paolo, Vallerio Paola, Varrenti Marisa, Casadei Francesca, Musca Francesco, Facchetti Rita, Di Blasio Anna M, Ravassa Susanna, Mancia Giuseppe, Giannattasio Cristina
  
  Abstract
  
  OBJECTIVE:
  Annexin A5 (AnxA5) has been previously linked to the presence of carotid and cardiac target organ damage (TOD) in the context of heart failure and rheumatologic patients. However, information is scant in the context of hypertension. Aim of our study was to evaluate AnxA5 in treated hypertension patients compared with normotensive controls and to determine whether it is associated with vascular and heart TOD evaluated as arterial stiffness, carotid plaque and left ventricular hypertrophy.
  
  METHODS:
  We enrolled 123 consecutive treated hypertension and 124 normotensive controls. TOD was evaluated as pulse wave velocity (PWV, complior), left ventricular hypertrophy (echocardiography) and intima-media thickness and carotid plaque presence (ecographic methods). AnxA5 levels was dosed and compared in patients with and without hypertension and with and without TOD.
  
  RESULTS:
  With similar age hypertension patients showed higher SBP, DBP and AnxA5 levels (13.9?±?11.1 vs 10.1?±?8.4?ng/ml, P?0.001) compared with controls. Regarding TOD hypertension showed higher PWV (8.5?±?1.8 vs 7.6?±?1.5?m/s, P?0.001) and LVMI (121.7?±?29.3 vs 113.5?±?21.1?g/m, P?0.05), whereas carotid intima-media thickness was superimposable. AnxA5 correlates with PWV (r?=?0.13, P?0.05) and DBP (r?=?0.15, P?0.01), whereas it has never been found as a significant independent predictor of TOD in linear regression analysis.
  
  CONCLUSION:
  Our data have shown that AnxA5 levels are increased in treated hypertension patients. In this condition, it is probably released in the plasma as a defensive mechanism through its anti-inflammatory and anticoagulants effects. We found a significant association with arterial stiffness, but AnxA5 was not found to be a significant predictor of TOD.

  Abstract
  
  Radiotherapy for breast cancer may expose heart and vessels to late radiation-induced complications. Although recent technical progress in radiation therapy (RT) has been associated with drastic reduction in cardiovascular (CV) mortality, the prolonged life expectancy of patients with cancer requires CV evaluation for many years. The aim of our study was to evaluate local changes in vascular and cardiac function because of previous breast RT. We enrolled 43 patients treated with RT 15 years ago for breast cancer. CV risk factors and atherosclerotic carotid damage were investigated in all women. We divided patients into 2 groups: R (n = 25) treated to right breast and L (n = 18) to left breast. All subjects were submitted to standard echocardiography and functional arteries evaluation by carotid-radial pulse-wave velocity (crPWV; Complior) and AIx (Sphygmocor; Atcor Medical). Global mean age was 69.5 ± 8 years old. CV risk factors were equally allocated in 2 groups. No patients had history of cardiac or artery disease. R had a significantly increased crPWV (9.9 ± 1.4 vs 8.9 ± 1.1, p = 0.001) on right arm compared with left arm, and in L group, crPWV was similarly higher on the left arm than on right arm (9.6 ± 1.5 vs 8.9 ± 1.4, p = 0.011). AIx was significantly increased in the ipsilateral arm only in L (32.1 ± 7.6 vs 28.3 ± 6.8, p = 0.05). Central blood pressure estimation was not different in the right and left arms. No correlations were found with hormone therapy or chemotherapy. Our data show a local arterial stiffening because of radiation that can be involved in increased CV risk in breast cancer-treated patients.

  Abstract
  
  BACKGROUND:
  EKG Tpeak-Tend (Tp-Te) interval, an index of transmural dispersion of myocardial repolarization, is gaining interest as possible cardiovascular prognostic variable. Evidence that this is the case in the general population is scanty, however. This was tested in the Pressioni Arteriose Monitorate E Loro Associazioni population.
  
  METHODS AND RESULTS:
  EKG, echocardiographic, office, home and ambulatory (24-h) blood pressure (BP), metabolic and laboratory data were assessed. Cardiovascular and all-cause mortality were evaluated over a mean follow-up of 16 years. Repetition of all measurements after 10 years allowed to evaluate also the risk of developing office and out-of-office hypertension and echocardiographic left ventricular hypertrophy. At baseline, Tp-Te adjusted for confounders (c) showed a significant correlation with office, home and 24-h blood pressure but not with left ventricular mass. The cTp-Te value predicted the risk of cardiovascular and all-cause mortality before and after adjustment for demographic and clinical variables, the increase being 31 and 13% for 1-SD cTp-Te increase, respectively (P?0.0001 and P?0.002). This was the case also in hypertensive patients in which the corresponding increase in risk with 1-SD increase of Tp-Te was 47 and 25% (P?0.05). cTp-Te did not predict the 10-year risk of developing office, home, ambulatory hypertension and left ventricular hypertrophy.
  
  CONCLUSION:
  Tp-Te interval retains an independent prognostic value both in the general population and in its hypertensive fraction. This easily and cheaply obtainable variable may be employed for improving cardiovascular-risk stratification, representing a useful measure to add to the recommended screening in hypertension.

  Abstract
  
  BACKGROUND:
  Heart failure with reduced ejection fraction (HFrEF) is characterized by activation of the sympathetic nervous system and increased arterial stiffness, leading to an impaired ventricular-vascular coupling. Baroreflex activation therapy (BAT) has been shown to reduce muscle sympathetic nerve activity (MSNA) and improve clinical status of patients with HFrEF. The purpose of this investigation was to determine the effects of BAT on arterial stiffness in HFrEF.
  
  METHODS AND RESULTS:
  MSNA, clinical variables, and parameters of central blood pressure (BP) and arterial stiffness were collected in 18 NYHA Class III HFrEF patients, nine receiving BAT and nine continuing with optimal medical management alone. Patients were followed for 3 months, with measurements at that time compared to baseline evaluation. Baseline characteristics of the groups were well matched. At 3 months, BAT did not improve central BP and arterial stiffness despite a significant amelioration of MSNA, NYHA class, Minnesota living with heart failure questionnaire score, number of heart failure medications and six-minute walking distance. The control group exhibited no significant changes in all the measured variables.
  
  CONCLUSIONS:
  Despite significant reductions in MSNA and clinical improvement, BAT does not appear to chronically modify arterial stiffness within this HFrEF cohort. Additional study is required to determine if this result applies to the HFrEF population as a whole.

  Abstract
  
  Aortic mural thrombi in a normal (non-aneurysmal or minimally atherosclerotic) vessel are an uncommon condition. They are usually located in the descending aorta and, less frequently, in the aortic arch or in the abdominal aorta. The typical clinical presentation is the appearance of symptoms/signs of peripheral arterial embolization, such as lower limb or visceral ischaemia, but these can also be accidentally found in asymptomatic patients. We report the case of a 40-year old man with untreated hypertension and dyslipidaemia admitted to hospital for atypical chest pain associated with an elevation in high-sensitivity troponin T with normal creatine kinase isoenzime MB creatine kinase isoenzyme. Elektrocardiogram (EKG) and transthoracic echocardiography were non-diagnostic; in order to exclude an aortic dissection, a gated chest computed tomography was performed and showed an aortic thrombus on a minimally atherosclerotic wall. Then, a transoesophageal echocardiography confirmed an aortic floating thrombus (7 × 4 mm). Cardiac surgeons advised against surgery and therapy with antiplatelet, low molecular weight heparin, ?-blocker, antihypertensive and lipid-lowering drugs was initiated. A complete resolution of the thrombus was observed at the 12-day tomographic control.

  Abstract
  
  Renal denervation (RD) is an intriguing treatment strategy for resistant hypertension. However, limited data are available about its long time efficacy as well as its effects on intermediate phenotypes like arterial stiffness and carotid IMT. 12 patients (9 males, mean 69 years) with resistant hypertension underwent bilateral RDN (Medtronic System) since April 2012 in Niguarda Ca' Granda Hospital (Milan). Patients were studied before intervention, and at 1, 3, 6 and 12 months after RD. Carotid intima media thickness (Esaote Mylab) and carotid-femoral pulse wave velocity (Complior, Alam medical) were assessed at each step. Compared to baseline, patients showed a marked reduction of office systolic blood pressure at each follow-up step (p

  Abstract
  
  INTRODUCTION AND OBJECTIVE:
  Blood pressure variability (BPV) within 24?h or between visits has been found to represent an independent risk factor for cardiovascular disease. The present study was aimed at determining whether a clinical significance can be given also to the BP variations occurring within a single clinical visit.
  
  METHODS:
  BPV was quantified as coefficient of variation and as standard deviation (SD) of the mean of three systolic SBP values within a visit in the context of a large-cross subclinical survey (BP-CARE) of treated hypertensive patients living in Eastern European countries. The study population was divided into coefficient of variation and SD quartiles and for each quartile a relationship was sought with a large number of cardiovascular risk factors based on patients' history, physical and laboratory examinations.
  
  RESULTS:
  The 6425 hypertensive patients had an age of 59.2?±?11 years (mean?±?SD); they were equally distributed by sex and displayed an average SD and coefficient of variation amounting to 5.1?±?6.2?mmHg and 3.5?±?4.0%, respectively. Compared with the lowest coefficient of variation quartile (Q1), patients in the highest quartile (Q4) showed a significantly greater prevalence of several cardiovascular risk factors, such as age (Q1: 58.5?±?11 vs. Q4: 60.3?±?11 years, P?0.001), serum total cholesterol (Q1: 213.0?±?46 vs. Q4: 216.4?±?51?mg/dl, P?0.05), blood glucose (Q1: 106.2?±?35 vs. Q4: 109.8?±?39?mg/dl, P?0.005), previous cardiovascular events (Q1: 57.4 vs. Q4: 63.9%, P?0.001), and resistant hypertension (Q1: 26.3 vs. Q4: 34.1%, P?0.001). They also showed higher office (Q1: 143.2?±?18 vs. Q4: 154.3?±?19?mmHg, P?0.001) and 24-h ambulatory SBP values (Q1: 134.8?±?17 vs. Q4: 141.2?±?18?mmHg, P?0.001). Similar results were obtained when BPV was expressed as SD.
  
  CONCLUSION:
  Our study provides evidence that greater within-visit BP variabilities are associated with a worse cardiovascular risk profile. This suggests that even this type of BPV may have clinical significance.

  Abstract
  
  BACKGROUND & AIMS:
  Iron accumulation within the arterial wall has been hypothesized to promote atherosclerosis progression. Aim of this study was to evaluate whether the hormone hepcidin and iron stores are associated with arterial stiffness in subjects with essential hypertension.
  
  METHODS:
  Circulating hepcidin, ferritin, and mutations in the hemochromatosis gene were compared between subjects included in the first vs. third tertile (n=284 each) of carotid-femoral pulse wave velocity (PWV) in an unselected cohort of patients with arterial hypertension.
  
  RESULTS:
  At univariate logistic regression analysis, high PWV was associated with higher ferritin levels (p=0.010), but lower hepcidin (p=0.045), and hepcidin ferritin/ratio (p
  CONCLUSIONS:
  In conclusion, hyperferritinemia is associated with high aortic stiffness and cardiac diastolic dysfunction, while low circulating hepcidin with high aortic stiffness.

  Abstract
  
  BACKGROUND:
  In the last 2 decades, new drugs that oppose the effects of vascular endothelial growth factor receptor (VEGFR), and thus angiogenesis, have considerably improved treatment of solid tumors. These anti-VEGFR drugs, however, are burdened by several side effects, particularly relevant on heart and vessels. The aim of this study was to analyze the changes in cardiovascular structure and function associated with use of anti-VEGFR drugs.
  
  METHODS:
  Twenty-nine patients (27 affected by renal and 2 by thyroid cancer), received treatment with anti-VEGFR drugs. Brachial blood pressure (BP), central BP, carotid-femoral pulse wave velocity (cfPWV), augmentation index (Aix), and several echocardiographic markers of systolic and diastolic left ventricular functions including global longitudinal strain were measured before starting treatment (T0), after 2 (T1), and 6 weeks (T2) of treatment.
  
  RESULTS:
  Anti-VEGFR treatment was accompanied by a significant increase of both peripheral (systolic BP +13±15.5mm Hg, diastolic BP +7.1±9.3mm Hg, P
  CONCLUSIONS:
  All the changes regarding BP and cfPWV appear early after treatment initiation and seem to be reversible if treatment is stopped, instead diastolic and systolic left ventricular function are persistently altered by anti-VEGFR drugs.

  Abstract
  
  OBJECTIVE:
  Scanty data are available on the accuracy of NT-proBNP in the diagnosis of HF and effects of comorbidities in very elderly patients.
  
  METHODS:
  Symptoms, signs, NT-proBNP, eGFR, Ht, CRP and the presence of cardiomegaly and pleuric effusion were assessed in 895 consecutive patients aged 86±4.3 years admitted to Emergency Department and used to define the diagnosis of HF according to Framingham criteria. Receiver operating characteristic curves (ROC) were used to calculate diagnostic performance and cutoff of NT-proBNP. Sensitivity (Sn), specificity (Sp), positive predictive value (PPV) and negative predictive value (NPV) were computed for all NT-proBNP cutoffs.
  
  RESULTS:
  Satisfactory diagnostic performance was obtained with a lower threshold of 980pg/mL (Sn 0.95; NPV 0.90) and a higher threshold of 5340 (Sp 0.85; PPV 0.76) but with 42.4% of patients in the uncertainty area. We determined a second couple of cutoffs (1470-4200) that reduced the gray-area to 27.4%, maintaining an acceptable diagnostic performance compared to commonly used cutoffs (300-1800). Ht, CRP and eGFR all correlated with NT-proBNP in groups with and without HF but none affected diagnostic performance.
  
  CONCLUSION:
  NT-proBNP performs satisfactorily for the diagnosis of HF in very elderly patients. Proposed threshold couple, compared with the most used cutoffs, showed a gain in Sp and PPV with a slightly lower performance in Sn and NPV and with a decrease in the gray-area with the second one. Our data do not support the use of different NT-proBNP cutoffs depending on eGFR, Ht and CRP.

  Abstract
  
  Early vascular aging is a process characterized by a reduction in arterial elastin with an increase in collagen that has been related to cardiovascular risk factor and can determine an increased arterial stiffness and central blood pressure. It can be measured by several non invasive methods and in different arterial segment. The present paper will focus on functional (local stiffness parameter) and structural (intima media thickness) carotid arteries alterations typically evaluated by ultrasound methods. Methodological, research and clinical issue has been reviewed.

  Abstract
  
  OBJECTIVE:
  Williams-Beuren syndrome (WBS) is a genetic disorder that involves elastin gene causing cardiovascular abnormalities and increased risk. However, data on arterial function in these patients are only few and conflicting. Aim of this study was to evaluate dynamic behaviour of central and peripheral blood pressure (BP) and arterial stiffness parameters early in the course of WBS.
  
  METHODS:
  We enrolled 19 WBS paediatric patients (age 13?±?4 years) and 23 age, height and BP-matched controls (10?±?4 years). We evaluated 24-h ambulatory BP values via an ambulatory blood pressure monitoring (ABPM) system (Mobil-O-Graph) also capable to calculate 24-h central BP and 24-h arterial stiffness parameters. Carotid-femoral PWV (cf-PWV) was assessed in all WBS individuals (Complior).
  
  RESULTS:
  BP values were similar in WBS and control, during the daytime and the night-time. The same behaviour applies to 24-h central BP. However, during the night, WBS showed heart rate values (HR; 78?±?10 vs. 71?±?9?bpm; P?0.03), augmentation index (Aix; 24.6?±?13.5% vs. 16.5?±?8.9%; P?=?0.03) and reflection magnitude (68 5.8 vs. 63.5 8.1; P?=?0.02) higher than controls. The HR, Aix and reflection magnitude reduction in the day-night shift was lower in WBS than in controls. Cf-PWV in WBS children did not differ when compared with their normalized expected value.
  
  CONCLUSION:
  In WBS children, the higher night-time HR, Aix and reflection magnitude and their impaired physiological reduction in the day-night shift suggests an abnormal sympathetic cardiovascular control, an augmented wave reflection and an increase in small arteries resistance. These alterations possibly due to a sympathetic overactivity can be regarded as earlier hallmarks of cardiovascular dysfunction in these patients.

  Abstract
  
  HIV infected subjects present an unfavorable cardiovascular (CV) risk profile that is determined by the infection itself, highly active anti-retroviral therapy (HAART) and other factors, such as chronic kidney disease (CKD). Information is scant and contradictory on whether these factors are associated with arterial stiffness and blood pressure (BP) alteration. Our study aimed to evaluate those parameters in HIV-positive subjects both with and without HAART and with and without CKD, which was defined as the presence of microalbuminuria with a normal glomerular filtration rate. We enrolled 94 HIV-infected subjects without known CV risk factors and compared them with 37 control subjects. We recorded brachial and central BP (pulse wave analysis) and pulse wave velocity ( SphygmoCor). HIV-positive subjects of similar ages and with similar BP values showed central pulse pressure values that were significantly greater than those of controls; this was also the case for the Aix value. Central systolic and pulse pressure values and Aix were significantly greater in HIV-positive subjects with HAART and CKD than in the other HIV-positive subgroups and control subjects. PWV was also superimposable between groups when the data were analyzed relative to the presence of HAART and CKD. Our study shows that the unfavorable CV risk profile associated with HIV infection includes an increase in both central BP and Aix. The central BP increase seems to be favored by renal damage, which apparently has a role in the early stages of the disease.

  Abstract
  
  BACKGROUND:
  Human immunodeficiency virus (HIV) infection itself and highly active antiretroviral treatment (HAART) have been proposed to be associated with a higher prevalence of metabolic syndrome, but, to date, prevalence and phenotype of metabolic syndrome among HIV subjects and the related structural and functional vascular alterations are not conclusively defined.
  
  METHODS:
  We analyzed the data of 108 HIV-infected subjects without known cardiovascular risk factors: 72 were on HAART (group A, age 46.5±7.5 years, clinical blood pressure 125.7/74.9±11.6/7.8?mmHg) and there 36 in a naïve group (group B, age 40.7±7.9 years, blood pressure 126/75.8±9.8/7.7?mmHg). A total of 224 healthy subjects served as controls (group C, age 44.9±6.9 years, blood pressure 123.7/75.7±9.8/7.1?mmHg). Arterial stiffness was measured by aorto-femoral pulse wave velocity (PWV, sfigmocor), and carotid intima media thickness (IMT) was measured by a semiautomatic echotracking system (Esaote-WTS).
  
  RESULTS:
  Metabolic syndrome was more frequent in HIV-positive subjects than in controls (19.4%, 13.8%, 4.5% for groups A, B, and C; P
  CONCLUSIONS:
  HIV subjects showed a higher prevalence and a different pattern of metabolic syndrome components. HAART, more than HIV infection per se, appeared to be responsible for the increased prevalence of metabolic syndrome and arterial function derangement.

  Abstract
  
  OBJECTIVE:
  Evidence exists that arterial stiffness, i.e. an independent predictor of cardiovascular and all-causes mortality, has a genetic component. The 9p21 region is associated with a greater susceptibility to coronary disease. Whether this can be ascribed to the fact that genes located on chromosome 9p may also regulate arterial stiffness is largely unknown, however. We evaluate the influence of single nucleotide polymorphisms (SNPs) from 9p on carotid-femoral pulse wave velocity (C-F PWV), measured via the Complior method, in a cohort of 821 hypertensive subjects.
  
  DESIGN:
  The selected tagSNPs were screened with a custom-designed 384-plex VeraCode GoldenGate Genotyping assay on Illumina BeadXpress Reader platform. Association analysis was done using PLINK considering C-F PWV as a quantitative trait (linear regression assuming an additive model) adjusting for sex, age, systolic blood pressure and body mass index (BMI). We used false discovery rate (FDR) to account for multiple testing.
  
  RESULTS:
  Although none of the 384 SNPs was significant after adjusting for multiple testing, probably due to the small sample size of the study population, a trend of association with C-F PWV was observed for rs300622 and rs2381640.
  
  CONCLUSIONS:
  These data suggest that SNPs located on chromosome 9p may affect arterial stiffness. Further studies are needed to confirm our finding on a larger sample and define the physiopathological link of the present results.

  Abstract
  
  Arterial distensibility can be measured either by echotracking or by nuclear magnetic resonance (MRI). Little information, however, is available on the comparison between the two methods and on the relationships between the results obtained with the two approaches and the arterial stiffness gold standard measurement, i.e., pulse wave velocity (PWV). In 28 normotensive subjects (age 33.0 ± 10.4 years, mean ± SD) we measured aortic diameter 1 cm above iliac bifurcation, aortic pulse pressure by tonometry and calculated arterial distensibility via the Reneman formulae for both methods. Aortic diameter and aortic distensibility were not superimposable and higher values were systematically detected with the MRI approach than with the ultrasound one. However, PWV showed a significant correlation with aortic distensibility values obtained by both methods (r = 0.50 and r = 0.49, p

  Abstract
  
  BACKGROUND:
  In patients with myocardial ischemia and coronary atherosclerosis, arterial stiffness and endothelial function are impaired. Whether these alterations can be favorably affected by successful coronary revascularization is debated.
  
  METHODS:
  We studied 39 hospitalized patients 59.3 ± 3.2 years old (mean ± SEM). In 21 patients with angiographic evidence of significant coronary artery stenosis, revascularization procedures were performed (stenting n = 11 and bypass surgery n = 10). The remaining patients had no significant stenosis and thus served as controls. Prerevascularization measurements included carotido-femoral pulse wave velocity (PWV), radial artery flow-mediated vasodilatation and a complete echocardiographic examination. The same measurements were performed 6 months later. Pharmacological treatment consisted of different cardiovascular drugs and remained substantially unchanged over the 6-month follow-up period.
  
  RESULTS:
  With the exception of an increased left ventricular mass index (LVMI; 130 ± 5.3 versus 105.8 ± 7.2 g/m(2), P
  CONCLUSION:
  Cardiac revascularization has no effect on arterial function, assessed either as arterial stiffness or as flow-mediated vasodilatation. On the contrary, the improvement in coronary blood flow triggers local cardiac changes, namely, a reduction in LVMI and an improvement in diastolic function.
