title: Pathogenesis of cocaine-induced ischemic heart disease. Autopsy findings in a 21-year-old man.
abstract: A 21-year-old man with a five-year history of recreational intravenous cocaine abuse developed chest pain within one minute and cardiopulmonary arrest within one hour following an injection. He died and, on autopsy, was found to have severe coronary obstructive lesions, as a result of chronic intimal proliferation, and acute platelet thrombosis. Secondary chronic and acute myocardial ischemic lesions also were observed. Cocaine-induced coronary artery spasm may have occurred and produced focal endothelial injury and platelet aggregation; this pathogenetic mechanism may have accounted for both the chronic and the acute coronary obstructive lesions. In addition, lymphocytic myocarditis was present and may have been related to the long-term cocaine abuse.
