Pulse pressure amplification and its determinants

2015

Background. Pulse pressure (PP) amplification expressed as the peripheral-to-central PP ratio has gained importance in the assessment of cardiovascular phenotypes and cardiovascular risk. The aim of the present study was to assess the relationship between PP amplification, large vessel parameters and peripheral blood pressure (BP) to gain insights into the amplification phenomenon. Methods. Peripheral BP, central BP and carotid-femoral pulse wave velocity (cfPWV) were assessed using the OMRON M6, SphygmoCor and Complior devices, respectively, in 741 adults attending the hypertension outpatient clinic. Analysis of covariance, partial correlations and multiple linear regression models were pe…

Association of MR-proadrenomedullin with cardiovascular risk factors and subclinical cardiovascular disease.

2012

Abstract Aims and background Midregional proadrenomedullin (MR-proADM) is a protein, which exerts various effects on the cardiovascular system. Recent studies underscored its prognostic implications in patients with acute dyspnea and cardiovascular diseases. Therefore, we aimed to determine the distribution of MR-proADM in the general population and to reveal potential associations of MR-proADM with cardiovascular risk factors and measures of subclinical cardiovascular disease. Methods and results MR-proADM plasma concentrations were determined in individuals of the population-based cohort of the Gutenberg Health Study ( N  = 5000) using a commercially available fluoroimmunoassay. Individua…

Relationship between aortic root size and glomerular filtration rate in hypertensive patients

2016

OBJECTIVE: Recent studies suggest that enlarged aortic root diameter (ARD) may predict cardiovascular events in absence of aneurysmatic alterations. Little is known about the influence of renal function on ARD. Our study was aimed to assess the relationships between glomerular filtration rate (GFR) and ARD in hypertensive subjects. METHODS: We enrolled 611 hypertensive individuals (mean age: 52 ± 15 years; men 63%). ARD was measured by echocardiography at the level of Valsalva's sinuses using M-mode tracings. It was considered as absolute measure, normalized to body surface area (ARD/BSA) and indexed to height (ARD/H). GFR was estimated by the Chronic Kidney Disease Epidemiology Collaborati…

Insulin-resistance HCV infection-related affects vascular stiffness in normotensives

2015

BACKGROUND AND AIMS. Arterial stiffness evaluated as pulse wave velocity, is an early marker of vascular damage and an independent predictor for cardiovascular events. We investigated if the insulin resistance/hyperinsulinemia chronic hepatitis C virus infection-related could influence arterial stiffness. METHODS. We enrolled 260 outpatients matched for age, body mass index, gender, ethnicity: 52 with never-treated uncomplicated chronic hepatitis C virus infection (HCV(+)), 104 never-treated hypertensives (HT) and 104 healthy subjects (NT). Pulse wave velocity was evaluated by a validated system employing high-fidelity applanation tonometry. We also measured: fasting plasma glucose and insu…

ObjectivesTo examine the lifetime, 5-year and past-year prevalence of homelessness among European citizens in eight European nations.DesignA nationally representative telephone survey using trained bilingual interviewers and computer-assisted telephone interview software.SettingThe study was conducted in France, Ireland, Italy, the Netherlands, Poland, Portugal, Spain and Sweden.ParticipantsEuropean adult citizens, selected from opt-in panels from March to December 2017. Total desired sample size was 5600, with 700 per country. Expected response rates of approximately 30% led to initial sample sizes of 2500 per country.Main outcome measuresHistory of homelessness was assessed for lifetime, …

Impaired exercise tolerance is associated with increased urine albumin excretion in the early stages of essential hypertension

2011

Background: Our aim was to investigate the relationship between impaired exercise capacity and albumin excretion level in the setting of never treated essential hypertension. Design and methods: For this purpose, 338 consecutive essential hypertensives (52 ± 8.5 years, 227 males, office BP = 148.6/96.1 mmHg) performed a negative for myocardial ischemia, maximal treadmill exercise testing and were classified based on the gender specific median value of the amount of metabolic equivalents (METs) achieved (10.1 ml/kg/min for women and 11 ml/kg/min for men) as fit ( n = 177) and unfit ( n = 161). All the participants underwent 24-h ambulatory BP monitoring, complete echocardiographic study inc…

Effect of time-of-day-specific strength training on muscular hypertrophy in men.

2009

The purpose of the present study was to examine effects of time-of-day-specific strength training on muscle hypertrophy and maximal strength in men. A training group underwent a 10-week preparatory training (wk 0-wk 10) scheduled between 17:00 and 19:00 hours. Thereafter, the subjects were randomized either to a morning or afternoon training group. They continued with a 10-week time-of-day-specific training (wk 11-wk 20) with training times between 07:00 and 09:00 hours and 17:00 and 19:00 hours in the morning group and afternoon groups, respectively. A control group did not train but was tested at all occasions. Quadriceps femoris (QF) cross-sectional areas (CSA) and volume were obtained b…

Endothelial function and other biomarkers of cardiovascular risk in frequent consumers of street food.

2012

Summary Background & aims Street food (SF) is defined as out-of-home food consumption, and generally consists of energy dense meals rich in saturated fats, and poor in fibers, vitamins and anti-oxidants. Though SF consumption may have unfavorable metabolic and cardiovascular effects, its possible association with endothelial function has not been considered. Methods Participants were recruited among those who took part in a previous study of ours, done in Palermo, Italy, which investigated the association between consumption of SF and health in 1002 people. In that study, a score of SF consumption was obtained by categorizing each of ten foods consumed less than or more than once a month (0…
