Cardiovascular effects of alcohol consumption.

Alcohol consumption has a major but complex impact on cardiovascular diseases. Both irregular and chronic heavy drinking occasions detrimentally impact on most major cardiovascular disease categories, whereas light to moderate drinking has been associated with beneficial effects on ischemic heart disease and ischemic stroke. Both detrimental and beneficial effects of alcohol consumption have been corroborated by biochemical pathways. The impact of alcohol consumption on cardiovascular disease should be evaluated within the context of other effects of alcohol on health.
