Increased carotid wall stress in vascular Ehlers-Danlos syndrome.

abstract：BACKGROUND:Impaired endothelium-dependent vasodilation is an early sign of atherosclerosis in hypercholesterolemic patients. We hypothesized that lipid-lowering therapy can improve endothelial function and that this effect is mainly mediated by increased bioavailability of nitric oxide (NO). METHODS AND RESULTS:In a r...
