Symptomatic coronary artery spasm following radiotherapy for Hodgkin's disease

Four years after mediastinal radiation for Hodgkin's lymphoma, a 32-year-old man developed angina at rest and with varying levels of physical activity. At coronary arteriography, 40 percent to 50 percent stenoses were seen in the left coronary artery; ergonovine induced severe coronary spasm. Treatment with diltiazem eliminated all anginal attacks.
