Dihydropyridine calcium channel blockers may possess antioxidant properties, and might improve micro and macrovascular structure and function. Combination treatment with an ACE inhibitor may have additional advantages, compared with a thiazide diuretic. The aim of the present study is to investigate the effects of a short-term treatment with lercanidipine, and to compare two combination treatments: lercanidipine + enalapril vs. lercanidipine + hydrochlorothiazide on structural alterations in retinal arterioles, on skin capillary density and on large artery distensibility...

OBJECTIVE: To explore the relationship between circulating adiponectin, leptin and vaspin with bone mineral density (BMD), arterial stiffness and vascular calcification in post-menopausal women. We hypothesised that adipokines produced by adipose tissue may be mediators of bone and cardiovascular disease (CVD) and explain, in part, the observed association between osteoporosis and CVD. DESIGN: We studied 386 ambulant community dwelling postmenopausal women aged (mean [SD] 61 [6...

INTRODUCTION: Chronic kidney disease (CKD) is associated with an increased risk of cardiovascular disease and mortality, which is thought to be caused by increased propensity towards vascular calcification (VC). Magnesium (Mg) inhibits phosphate-induced VC in vitro and in animal models and serum Mg is inversely associated with cardiovascular mortality in predialysis CKD and in end-stage renal disease. This paper will describe the design and rationale of a randomised double-blinded placebo-controlled multicentre clinical trial, which will investigate whether oral Mg supplementation can prevent the progression of coronary artery calcification (CAC) in subjects with predialysis CKD...

A decreased aortic-to-brachial pulse pressure (PP) amplification, which is independently associated with cardiovascular outcomes, may index several aortic functional changes. However, that aortic functional change most likely to account for this effect is uncertain. In 706 randomly selected community participants of African ancestry with a mean age of 44.4 ± 18.2 years, we assessed aortic function using radial applanation tonometry and SphygmoCor software (including forward [Pf] and backward [Pb] wave separation analysis assuming a triangular flow waveform) and left ventricular mass index (LVMI) (echocardiography)...

BACKGROUND: Black people have a higher risk of developing hypertension and presenting higher vascular stiffening. Our aim was to investigate whether the association between race and aortic stiffness could be explained by differences in the primary risk factors. METHODS AND RESULTS: We analyzed data from 11 472 adults (mean age, 51.9±8.9; 53.8% female) self-reported as white (n=6173), brown (n=3364), or black (n=1935). Their carotid-to-femoral pulse wave velocity (cf-PWV) as well as clinical and anthropometric parameters were measured...

Systemic lupus erythematosus (SLE) is associated with increased cardiovascular risk. This study aims to derive a more precise estimation on pulse wave velocity (PWV) level in patients with SLE and related factors. A literature search was performed using PubMed, EMBASE, and The Cochrane Library databases, studies published up to February 28, 2017, in English. Pooled standardized mean difference (SMD) with 95% confidence interval (CI) was calculated by fixed-effect or random-effect model analysis. Heterogeneity test was performed by the Q statistic and quantified using I(2); publication bias was evaluated using a funnel plot and Egger's linear regression test...

OBJECTIVE: It is well known that applied stress induces electrical potentials in bone. We have experimentally studied whether induced potentials could be found in bone using an ultrasound irradiation system similar to low-intensity pulsed ultrasound (LIPUS). MATERIALS AND METHODS: Circular plate specimens (diameter 10 mm, thickness 1 mm) were obtained from bovine femora in order to determine if bone behaved as a piezoelectric material. Using these specimens, ultrasound receivers were fabricated...

INTRODUCTION AND OBJECTIVES: Air pollution and insufficient physical activity have been associated with inflammation and oxidative stress, molecular mechanisms linked to arterial stiffness and cardiovascular disease. There are no studies on how physical activity modifies the association between air pollution and arterial stiffness. We examined whether the adverse cardiovascular effects of air pollution were modified by individual physical activity levels in 2823 adults aged 50-81 years from the well-characterized Swiss Cohort Study on Air Pollution and Lung and Heart Diseases (SAPALDIA)...

Alzheimer disease (AD) is an irreversible, progressive brain disorder that causes slow loss of memory and thinking skills, normally leading to death in 3-9 y. The etiology of AD is not fully understood but is widely believed to be induced by the production and deposition of amyloid-β peptide in the brain. Recently, a correlation was discovered between amyloid-β deposition and atherosclerosis in the cerebral arteries of postmortem brains, indicating that amyloid-β promotes atherogenesis and that in turn atherosclerosis promotes brain amyloid-β accumulation...

BACKGROUND: Poor glycemic control is associated with impaired left ventricular (LV) diastolic function in patients with type 2 diabetes mellitus (T2DM). Inappropriate LV mass increase and accelerated aortic stiffening were suggested to participate on deterioration of diastolic function. The present study investigated the inter-relationships between glycemic control, early diastolic and systolic longitudinal velocity of mitral annulus, LV mass and aortic stiffness in T2DM patients free of cardiovascular disease and with preserved LV ejection fraction, and compared them with those observed in healthy volunteers of similar age and sex distribution...

INTRODUCTION: Many studies have highlighted the important role of PCSK9 in the development of cardiometabolic changes and its possible function as a biomarker of myocardial infarction or ischemic heart disease. This study aimed to determine the relationship between circulating PCSK9 levels and subclinical vascular changes in the group of low risk patients without manifest cardiovascular diseases. METHODS: In this study, 120 healthy patients, free of manifest cardiovascular diseases, diabetes mellitus, and without lipid-lowering therapy, were divided into three groups based on BMI: normal weight (N = 50), overweight (N = 30), and obese (N = 40)...

OBJECTIVE: Stiffening of the aorta often precedes coronary events, but little is known about the aetiological mechanism. We hypothesized that the predisposition to myocardial ischemia could be attributable to aortosclerosis-induced alterations in the central haemodynamics during diastole. METHODS: Using noninvasive tonometry and ultrasonography, we investigated the arterial pressure pulse waveforms, pulse wave velocities (PWVs) and compliance in 222 patients with hypertension...

The scope of the present study is to investigate the change of elastic modulus with the physical and mechanical properties of porcelain tiles. In the study, porcelain tiles were sintered at different temperatures and at different heating rates to obtain minimum water absorption (%). After this, the time of flight of longitudinal and shear ultrasonic waves was measured through the tile. The time of flight of ultrasonic waves was measured using contact ultrasonic transducers operating on a pulse-echo mode. Using the time of flight of the ultrasonic waves and the thickness of the tiles, the velocity of the waves was determined...

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...
