title: Cardiovascular effects of cocaine: an autopsy study of 40 patients.
abstract: From September 1983 through November 1986, autopsies were performed on 6810 patients at the Office of the Maryland Medical Examiners; of these 40 had detectable cocaine, its metabolites, or both in body fluids. These patients were divided into two groups: natural cocaine-associated deaths (31 patients, mean age 28 +/- 5 years, blood level of cocaine 5.3 +/- 8.1 mg/L) and homicide deaths with detectable cocaine (nine patients, mean age 33 +/- 8 years, blood level of cocaine 0.3 +/- 0.3 mg/L). Cocaine-associated deaths were compared to a control group of 27 victims of sudden traumatic death (mean age 34 +/- 5 years). Total thrombotic occlusion of the left anterior descending coronary artery overlying mild coronary atherosclerosis occurred in one patient with cocaine-associated death. Results of histologic examination showed myocarditis (mononuclear infiltrate) in 8 of 40 (20%) patients dying with detectable cocaine in body fluids compared to 1 of 27 victims of sudden traumatic death (3.7%, p less than or equal to 0.05). Contraction band necrosis occurred in 25% of cocaine-associated deaths compared to a 41% incidence among victims of sudden traumatic death. We conclude that myocarditis occurs frequently in patients dying of cocaine abuse and may represent microvascular injury.
