To investigate the effects of fasting and postprandial glucose on endothelial cell function and intima-media thickness, we studied 60 men with cardiovascular risk factors. Postischemic, endothelium-dependent vasodilatation was measured after 3 minutes of ischemia at the radial artery with high-resolution echo tracking. Common carotid artery intima-media thickness was measured by B-mode ultrasou...

Although the etiology of varicose veins remains unknown, recent studies have focused on endothelial cell integrity and function because the endothelium regulates vessel tone and synthesizes many pro- and anti-inflammatory factors. The aim of this study was to investigate the evidence involving the endothelium in the development of varicose vein disease. In addition, tissue remodeling was invest...

objective(s): atherosclerosis is an important risk factor for coronary heart disease. neuropeptide y (npy) and its receptors, located in peripheral tissue such as white adipose tissue, have been linked to obesity and fat storage. the role of npy in atherosclerosis has not yet been fully studied, so this study was conducted to further investigate the effect of biie 0246, an npy receptor antagoni...

Arteriovenous fistula (AVF) failure is mainly due to venous stenosis characterized by significant amount of intima-media thickening (IMT), probably in the presence of negative (inward) remodeling. Our hypothesis is that the longitudinal changes in wall shear stress (WSS) within different configurations of AVF can influence remodeling factors (changes in luminal diameter (ΔDh ) and IMT) during i...

OBJECTIVE Vascular remodeling of the carotid artery with intima-media thickness (IMT) is an important predictive factor for human cardiovascular disease. We characterized a mouse model of vascular remodeling. METHODS AND RESULTS The left external and internal carotid branches were ligated so that left carotid blood flow was reduced to flow via the occipital artery. In response to partial liga...

OBJECTIVE With increasing interest in the role of non-traditional lipid risk factors in coronary artery disease, we undertook this study to relate LDL subclass size and carotid intima-media thickness of the common carotid artery in coronary artery disease patients. METHODS The study was conducted in 106 patients during their first visit (study group I) and after 12 months (study group II). In...

Whether endothelial dysfunction in essential hypertension is a cause or a consequence of structural vessel wall alterations is not known. The purpose of the present study was to compare flow-mediated vasodilation and mechanical vessel wall properties of large arteries between never treated mild essential hypertensive patients with normal intima-media thickness (IMT) and those exhibiting intima-...

Carotid intima-media thickening (CIMT) is a marker of both arteriosclerotic and atherosclerotic risks. Technological advances have semiautomated CIMT image acquisition and quantification. Studies comparing manual and automated methods have yielded conflicting results possibly due to plaque inclusion in measurements. Low atherosclerotic risk subjects (n = 126) were recruited to minimise the effe...

OBJECTIVE Postprandial hyperglycemia observed in type 2 diabetes mellitus is a risk factor for atherosclerosis. The aim of this study was to investigate the effect of strict glycemic control by nateglinide on common carotid far wall intima-media thickness in type 2 diabetic patients who were already under good glycemic control. METHODS AND RESULTS We performed an open labeled randomized prosp...
