Drinking in moderation has been found to help those who have suffered a heart attack survive it.    However, excessive alcohol consumption leads to an increased risk of heart failure .  A review of the literature found that half a drink of alcohol offered the best level of protection. However, they noted that at present there have been no randomised trials to confirm the evidence which suggests a protective role of low doses of alcohol against heart attacks.  However, moderate alcohol consumption is associated with hypertension.  There is an increased risk of hypertriglyceridemia , cardiomyopathy , hypertension , and stroke if 3 or more standard drinks of alcohol are taken per day.
