Cardiac pathologic findings in three unusual cases of sudden cardiac death related to anorexiant drugs

Amphetamine congeners can be prescribed as anorexiant drugs, despite their potential side effects, including cardiac toxicity. However, the morphologic features of cardiac damage related to protracted use of these compounds are unknown. We provide a detailed description of cardiac autopsy findings in three cases of sudden death associated with protracted use of high-doses of phendimetrazine and/or phenylpropanolamine or bupropion prescribed as anorexiants, in association with other compounds. The main cardiac findings were similar in all three cases: i) mild–moderate hypertrophy of the left ventricle and/or the septum; ii) myocardial non-ischemic scarring (mid-mural and/or sub-epicardial) appearing as discrete foci or with a band/like morphology; iii) mild–moderate intramural small vessel disease, in absence of significant epicardial coronary artery stenosis; iv) acute/recent inflammatory lesions consistent with toxic myocarditis.
