Chemotherapy-induced myocardial infarction in a young man with Hodgkin's disease

A 32-year-old male with stage IIIA nodular sclerosing Hodgkin's disease and no cardiac risk factors presented with chest pain after receiving chemotherapy consisting of multiple drugs, including vinca alkaloids. He completed an uncomplicated anterior wall myocardial infarction. Coronary angiography documented the absence of significant coronary artery disease. Exercise stress testing with gated scan confirmed loss of anterior wall motion and a decreased left ventricular ejection fraction. Vascular toxicity, including, rarely, myocardial infarction, has been reported following antineoplastic regimens containing vinca alkaloids. Hypercoagulable states, cardiac invasion by tumor, and coronary artery spasm are possible etiologies. Of these, coronary artery spasm appears most likely. Management should include discontinuation of the offending drug and supportive care.
