There have been few studies that have tested the acute effects of alcohol on heart function. A new study shows how the low levels of alcohol effects the left ventricular (LV) and right ventricular (RV) performance, which collectively pump blood to the entire body. The functions of the two ventricles are highly differentiated.

The study used sixty-five healthy volunteers, thirty-five men and twenty-nine women--all of whom were in their twenties, to participate. On one occasion they were asked to drink five ml/kg of Italian red wine and the second an equal amount of fruit juice. The researchers took measurements at baseline as well as an hour after ingestion. The study found that low doses of red wine led to an acute depression in LV function and an acute increase in RV function. This prompted the researchers to conclude that even low doses of alcohol, which are common and considered socially acceptable, can cause acute cardiac toxicity. The study is the first of its kind.
