Randomized Controlled Trial
Effects of resveratrol on vascular tone and endothelial function of human saphenous vein and internal mammary artery.
The polyphenolic compound resveratrol presented in red wine has potent cardiovascular effect in animal. Here, we investigated the ability of resveratrol to relax human coronary bypass grafts, saphenous vein and internal mammary artery and also its effect on their endothelial reactivity. ⋯ Resveratrol produced mainly endothelium-dependent and nitric oxide-mediated vasodilation in human internal mammary artery but partially in saphenous vein rings and improved their endothelial reactivity. This may have a therapeutic potential in cardiovascular diseases.
