Does chronic ethanol administration cause irreversible cardiomyopathy?
Does chronic ethanol administration cause irreversible cardiomyopathy?
Chronic alcoholism is a significant cause of dilated cardiomyopathy, with the severity of cardiac dysfunction linked to cumulative ethanol exposure.
Links cumulative ethanol dose to DCM severity; leaves open reversibility with abstinence and needs prospective confirmation.
Chronic alcoholism is one of the most important causes of dilated cardiomyopathy, and a large proportion of chronic alcoholics demonstrate impairment of cardiac function. The development of cardiac dysfunction is apparently related to the total lifetime dose of ethanol. Studies in experimental animals have demonstrated that both acute and chronic ethanol administration impair cardiac contractility. However, the relationship, if any, between the acute effects of alcohol and the development of irreversible cardiomyopathy remain to be elucidated.
