RT Journal Article SR Electronic T1 Relation between alcohol intake, myocardial enzyme activity, and myocardial function in dilated cardiomyopathy. Evidence for the concept of alcohol induced heart muscle disease.

On the basis of the drinking history twenty patients were classified as being in an abstinent or light drinking group and eighteen patients as being in a heavy drinking group (daily alcohol intake in excess of 80 g or cumulative lifetime intake exceeding 250 kg). Activities of myocardial creatine kinase, lactate dehydrogenase, alpha hydroxybutyric dehydrogenase, malic dehydrogenase, and aspartate amino-transferase were all higher in the heavy drinkers and myocardial enzyme activity correlated with cumulative lifetime alcohol intake, maximum daily intake, and recent daily intake. Activities of creatine kinase, alpha hydroxybutyric dehydrogenase, and malic dehydrogenase correlated with ejection fraction, irrespective of the alcohol intake of the patient. These findings were not altered by exclusion of patients with hypertension. The results indicate that among patients with dilated cardiomyopathy there is a group characterised by a high alcohol intake and raised myocardial tissue enzymes which supports the concept of alcoholic heart muscle disease as a distinct entity.
