Precocious myocardial infarction after radiation treatment for Hodgkin's disease.

A 26-year-old man received extensive cardiac radiation in the course of treatment of mediastinal Hodgkin's disease, and six years later, he experienced an acute myocardial infarction. Angiographic studies demonstrated extensive atherosclerotic abnormalities in the coronary arterial system. It is suggested that radiation-induced injury was a provocation of these precocious arterial abnormalities.
