title: [Moderate alcohol consumption and cardiovascular diseases].
abstract: While excessive ethanol consumption can result in higher rate of morbidity and mortality resulting from several diseases including cancer and cirrhosis, epidemiological studies suggest that moderate alcohol ingestion reduces the risk of cardiovascular diseases. However, the precise mechanisms by which moderate alcohol consumption protects against coronary heart disease (CHD) is not fully understood. Epidemiological studies suggest that alcohol consumption influences several risk factors for CHD including blood pressure, plasma cholesterol levels, platelet function, and fibrinolytic parameters, preventing both vascular thrombosis and occlusion. Turning to molecular and cellular levels, ethanol has been shown to act on several signal transduction mechanisms involve in the inhibition of smooth muscle cells proliferation and migration and in the activation of the release of vasoactive factors from vascular cells such as nitric oxide (NO). The latter is of importance since NO has been shown to possess antioxidant, antiaggregant properties, to regulate vascular tone and to inhibit both proliferation of smooth muscle cells and adhesion of leukocytes. Altogether, the above mentioned beneficial properties of moderate concentration of ethanol might help to explain the cardio- and vascular protection induced by ethanol. This review compels several bibliographic data concerning the cardiovascular effect of moderate alcohol consumption.
