Estimation of metabolic syndrome heritability in three large populations including full pedigree and genomic information.

Metabolic syndrome is a complex human disorder characterized by a cluster of conditions (increased blood pressure, hyperglycemia, excessive body fat around the waist, and abnormal cholesterol or triglyceride levels). Any of these conditions increases the risk of serious disorders such as diabetes or cardiovascular disease. Currently, the degree of genetic regulation of this syndrome is under debate and partially unknown.

Management of supine hypertension in patients with neurogenic orthostatic hypotension: scientific statement of the American Autonomic Society, European Federation of Autonomic Societies, and the European Society of Hypertension.

: Supine hypertension commonly occurs in patients with neurogenic orthostatic hypotension due to autonomic failure. Supine hypertension promotes nocturnal sodium excretion and orthostatic hypotension, thus, interfering with quality of life. Perusal of the literature on essential hypertension and smaller scale investigations in autonomic failure patients also suggest that supine hypertension may predispose to cardiovascular and renal disease.

Consensus statement on the definition of neurogenic supine hypertension in cardiovascular autonomic failure by the American Autonomic Society (AAS) and the European Federation of Autonomic Societies (EFAS) : Endorsed by the European Academy of Neurology (EAN) and the European Society of Hypertension (ESH).

Purpose: Patients suffering from cardiovascular autonomic failure often develop neurogenic supine hypertension (nSH), i.e., high blood pressure (BP) in the supine position, which falls in the upright position owing to impaired autonomic regulation.

Trends in Prevalence, Awareness, Treatment, and Control of Blood Pressure Recorded From 2004 to 2014 During World Hypertension Day in Italy.

Estimates of blood pressure (BP) control in real life are not systematically collected in Italy. We evaluated trends in systolic/diastolic BP levels, as well as prevalence, awareness, treatment, and control rates of hypertension among adult individuals visiting open checkpoints during the 2004 to 2014 annual editions of World Hypertension Day. Hypertension was defined as BP level ≥140/90 mm Hg or use of antihypertensive medication, whereas BP control was defined as BP level <140/90 mm Hg.

Blood pressure levels and control in Italy: comprehensive analysis of clinical data from 2000-2005 and 2005-2011 hypertension surveys.

This analysis is aimed to determine blood pressure (BP) levels and BP control rates in a large population of hypertensive patients in Italy. Data were taken from two large and inclusive cross-sectional surveys, which covered two distinct and subsequent time periods (2000-2005 and 2005-2011, respectively). Observational clinical studies and surveys, which reported average systolic/diastolic clinic BP levels, proportions of treated/untreated and controlled/uncontrolled patients, and prevalence of cardiovascular risk factors in hypertensive patients followed in either outpatient clinics, hypertension centres or general practice, were considered for the analyses.

Heritability of blood pressure through latent curve trajectories in families from the Gubbio population study.

Background And Objectives: Prospective investigations on cardiovascular risk factors in populations provide a unique opportunity to dissect time-dependent quantitative complex traits, such as arterial blood pressure (BP), into their polygenic and environmental components. BP heritability analyses were carried out on 2620 patients belonging to 711 nuclear pedigrees that could be followed up throughout 25 years in the Gubbio Population Study.

Methods: Each patient's BP serial measurements were summarized into individual intercepts (expected values at baseline) and slopes (time-related changes), which were predicted through latent curve models.

Target organ damage in hypertensive patients: correlation between retinal arteriovenular ratio and left ventricular geometric patterns.

Early evaluation of cardiovascular (CV) risk in hypertensive patients is of primary importance and studies of retinal vessels can be helpful. The aim of this study is to assess the correlation between retinal vessel changes and target organ damage (TOD), expressed as left ventricular remodelling (LVR) or hypertrophy (LVH). We evaluated 60 treated hypertensive individuals (mean age 60.

Experimental animal models of myocardial damage in regenerative medicine studies involving adult bone marrow derived stem cells: ethical and methodological implications.

Cardiac performance after myocardial infarction is compromised by ventricular remodeling, which represents a major cause of late infarct-related chronic heart failure and death. In recent years, the scientists' interest has focused on the hypothesis that the administration of bone marrow progenitors, following myocardial infarction, could ameliorate left ventricular remodeling by continuing to differentiate along the haematopoietic lineage. This approach has been developed minding to the consolidated use of transfusions to restore lost or depleted blood components and, therefore, as an enriched dose of various progenitors, generally autologous, injected peripherally or directly in the infarcted area.

Facts and fallacies of blood pressure control in recent trials: implications in the management of patients with hypertension.

A large body of clinical trial data indicates that a given difference in blood pressure (BP), as measured in the clinic, results in a given difference in outcome. This correlation underpins current US and European guidelines for the management of hypertension. However, findings from recent comparative trials may appear inconsistent with a fixed relationship between BP lowering and outcome benefit, at least at all BP ranges, at all levels of total cardiovascular risk and with all drug combinations.

Potential advantages of cell administration on the inflammatory response compared to standard ACE inhibitor treatment in experimental myocardial infarction.

Background: Bone Marrow (BM) progenitor cells can target the site of myocardial injury, contributing to tissue repair by neovascolarization and/or by a possible direct paracrine effect on the inflammatory cascade. Angiotensin Converting Enzyme inhibitors (ACE-I) are effective in reducing mortality and preventing left ventricular (LV) function deterioration after myocardial infarction.

Methods: We investigated the short term effects of BM mononuclear cells (BMMNCs) therapy on the pro-inflammatory cytokines (pro-CKs) and on LV remodelling and compared these effects over a standard ACE-I therapy in a rat model of myocardial cryodamage.

Left ventricular diastolic dysfunction in elderly hypertensives: results of the APROS-diadys study.

Background: A number of patients with chronic heart failure (CHF) have diastolic but not systolic dysfunction. This occurs particularly in the elderly and in hypertension, but the prevalence of diastolic dysfunction in elderly hypertensives without CHF has never been investigated systematically.

Methods And Results: The Assessment of PRevalence Observational Study of Diastolic Dysfunction (APROS-diadys) project was a cross-sectional observational study on elderly (age >/= 65 years) hypertensives without systolic dysfunction [left ventricular ejection fraction (LVEF) >/= 45%] consecutively attending hospital outpatient clinics in Italy, in order to establish the prevalence of echocardiographic signs of diastolic dysfunction according to various criteria, and to correlate them with a number of demographic and clinical characteristics.

Direct visualization of neo-vessel formation following peripheral injection of bone marrow derived CD34+ cells in experimental myocardial damage.

The definitive fate of peripherally injected PKH26 labelled bone marrow mononuclear cells expressing the CD34+ antigen following experimental myocardial cryodamage in rats (n=10) has been examined by direct visualization on photoconverted light and electron microscopy images. One week after the injection in each rat of about 150,000 CD34+ cells early stage PKH26+ vascular structures were localized in the infarcted areas, suggesting that a potential benefit of this therapeutic approach consists in the regeneration of the vasculature.

Assessment of selective homing and contribution to vessel formation of cryopreserved peripherally injected bone marrow mononuclear cells following experimental myocardial damage.

In view of a potential clinical use we aimed this study to assess the selective homing to the injured myocardium and the definitive fate of peripherally injected labeled and previously cryopreserved Bone Marrow Mononuclear cells (BMMNCs). The myocardial damage (cryoinjury) was produced in 59 rats (45 treated, 14 controls). From 51 donor rats 4.

Hypertension: which aspects of hypertension should we impact on and how?

Cardiovascular complications may, to a large extent, be prevented by lowering blood pressure in hypertensive patients. International recommendations currently stress the importance of reaching values of below 140/90 mmHg in each patient or even lower in the case of concomitant diabetes or renal impairment. It is currently considered crucial to control the systolic pressure as well as the diastolic pressure, in particular because the relationship between cardiovascular risk and blood pressure is closer for the systolic than the diastolic value.

Zofenopril plus hydrochlorothiazide: Combination therapy for the treatment of mild to moderate hypertension.

Achieving target blood pressure (BP) levels in clinical practice is one of the main challenges for physicians in the management of patients with hypertension. It is now recognised that the majority of patients will require at least two antihypertensive drugs to achieve optimal BP control; the use of combination therapy as first-line treatment is also increasing as BP goals of antihypertensive therapy become more ambitious. The fixed combination of zofenopril/hydrochlorothiazide (HCTZ) 30/12.

Findings and implications of the Study on COgnition and Prognosis in the Elderly (SCOPE) - a review.

The Study on Cognition and Prognosis in the Elderly (SCOPE) assessed the effect of candesartan on cardiovascular and cognitive outcomes in elderly patients (aged 70-89 years) with mild to moderate hypertension. Patients were randomized to treatment with candesartan 8-16 mg daily (n = 2477) or placebo (n = 2460) and followed for 3.7 years on average.

Traditional and emerging cardiovascular and renal risk factors: an epidemiologic perspective.

Patients with chronic kidney disease (CKD) represent an important segment of the population (7-10%) and, mostly because of the high risk of cardiovascular complications associated with renal insufficiency, detection and treatment of CKD is now a public health priority. Traditional risk factors can incite renal dysfunction and cardiovascular damage as well. As renal function deteriorates, non-traditional risk factors play an increasing role both in glomerular filtration rate (GFR) loss and cardiovascular damage.

Endothelial colony forming capacity is related to C-reactive protein levels in healthy subjects.

The majority of clinical studies on endothelial progenitor cells (EPCs) focuses on the role of these cells in cardiovascular diseases and no systematic studies exist regarding their variations in healthy subjects. In order to define the burden of angiogenesis in physiological conditions we assessed the frequency of peripheral blood endothelial colonies (PB-ECs) and their relation with other factors possibly involved in their function such as high-sensitivity C-reactive protein (hs-CRP), endothelial cell-specific mitogen factor (VEGF) and tissue inhibitor of metalloproteinases-1 (TIMP-1) in a highly selected healthy population. A PB sample was obtained from 37/47 healthy subjects (age 40.

High-altitude trekking in the Himalayas increases the activity of circulating endothelial cells.

Circulating endothelial progenitor cells (EPCs) are believed to contribute to vascular homeostasis; unfortunately, the response of EPCs in physiological conditions remains largely unknown. Herein we report our observations of a 44-year-old healthy subject after a trek in the Himalayas that support high-altitude hypoxia and exercise oxygen demands are strong stimuli for clonogenic endothelial cell activation and activity, as shown by the increase in the number of mature EPCs and in the endothelial colony-forming unit capacity. Both of these effects were completely reverted at sea level, 45 days after the subject's trek.

Clinical pharmacodynamics of nebivolol: new evidence of nitric oxide-mediated vasodilating activity and peculiar haemodynamic properties in hypertensive patients.

New evidence from recently completed clinical studies performed with nebivolol, a highly selective beta-1 beta-blocker, endowed with additional vasodilating activity mediated by nitric oxide (NO) endothelial release, confirm previous findings that nebivolol differs from other beta-blocking agents and that the combination of beta-1 blockade and NO-mediated vasodilation not only potentiates the blood pressure lowering activity, but leads to a broader favourable haemodynamic profile, which is clinically relevant to the treatment of hypertensive patients. In particular, six new studies focusing on the vasodilation properties of nebivolol demonstrated that: (i) its blood pressure lowering effect is accompanied by a vasodilating action that is seen after single and chronic administration of the usual antihypertensive oral dose of 5 mg once daily; (ii) the vasodilation can be documented systemically, at various regional vascular beds and skin microcirculation, and is accompanied by increased small arterial distensibility; (iii) the NO-endothelium-dependency of its vasodilating action is shown by the model of forearm or cutaneous vasodilating response to acetylcholine and by the blockade of the nebivolol-induced local vasodilation by a blocker of the arginine-NO cascade, L-NMMA. Two more studies demonstrated the ability of nebivolol to increase NO concentrations through preservation of NO from oxidative degradation, and not only by stimulation of its synthesis.
