Constituents of red wine other than alcohol improve endothelial function in patients with coronary artery disease.

Background: Several studies suggest that red wine is beneficial in coronary artery disease (CAD). Although the long-term effect of moderate red wine consumption on endothelial function is currently under investigation, there is little knowledge about its effect on postprandial endothelial function and haemostatic factors. The aim of the present study was to investigate the postprandial effects of alcohol content and the antioxidants of red wine on endothelial function and fibrinogen levels in CAD patients.
