Alcohol and Cardiovascular Disease: Helpful or Hurtful.

ABSTRACT

Alcohol has been considered throughout history as both a tonic and a poison. The answer as to which likely depends on one's current health, the amount one consumes, and with what regularity. In examining the relationship of alcohol and cardiovascular health, most, but not all, epidemiological studies suggest that light to moderate alcohol consumption can reduce the incidence of coronary artery disease (CAD), ischemic stroke, and peripheral arterial disease events. Conversely, abuse of alcohol can lead to cardiomyopathy, heart failure, sudden death, and hemorrhagic strokes. In this article, we review the literature studying the effects of alcohol on coronary artery disease and stroke. A recently published study concluded there was no amount of alcohol per day that was heart healthy. Yet more than one hundred previous studies have found that people who drink in moderation have a lower risk of cardiovascular disease events when compared to those who do not drink or drink heavily. Moderate drinking is defined as one to two drinks per day; where one drink is defined as 12 ounces of beer, 5 ounces of wine or 1.5 ounces of hard liquor. In this article we reviewed the data suggesting that consuming alcohol in moderation on a regular basis-as opposed to 7 drinks on Saturday night-could have cardiovascular protective effects.
