Summary
A histologic study of hearts was made in nine cases of sudden death (average age 32 years) in methamphetamine abusers. Myocardial hypertrophy and disorganization as well as fibrosis were predominant, and only one case showed coronary atherosclerosis. Since the myocardial changes observed in the present study were similar to those typically seen in hypertrophic cardiomyopathy, it is possible that excess secretion of catecholamines, particularly norepinephrine, induced by methamphetamine abuse is associated in some way with the development of hypertrophic cardiomyopathy.
