ABSTRACT

Objectives: Excessive and prolonged consumption of alcohol can damage myocardium, causing congestive heart failure which is considered Alcoholic Cardiomyopathy. It has been postulated that there may be regression of this cardiomyopathy when alcohol is discontinued. The aim of the study is to know the prevalence of alcoholic cardiomyopathy in patients with dilated cardiomyopathy in a concentration hospital in western Mexico and to report the long-term regression rate of this cardiomyopathy by discontinuing alcohol consumption. Methods: From January 1988 to February 2013, 387 consecutive patients with a diagnosis of dilated cardiomyopathy were included; cases with ventricular dilation secondary to ischemic heart disease, valvular heart disease, systemic or pulmonary arterial hypertension, pericardial disease or congenital heart disease were excluded, andothers that directly affect myocardium. Results: 49 (12.6%) met criteria for the diagnosis of Alcoholic Cardiomyopathy. All were inIII o IV functional class of the New York Heart Association classification, with ejection fraction ‹of 40%.34.6% showed regression of left ventricular systolic dysfunction, 16.3 died due to cardiac insufficiency resistant to medical treatment, the rest presented clinical improvement of their functional class remaining in functional class I or II of NYHA. Conclusions: Alcoholic cardiomyopathy is common in our country, but with specialized medical treatment for congestive heart failure and suspension of alcohol consumption, great clinical improvement and even regression of this cardiomyopathy can be obtained in about a third part of the cases.
