title: A normal coronary arteriogram in a very young man with Prinzmetal's variant angina: Case report with review of the literature.
abstract: The case of a very young man with Prinzmetal's variant angina and a normal coronary arteriogram is described. While in the hospital for diagnosis, he experienced severe chest pain accompanied by transient ST segment elevation. After intravenous administration of Ergonovine Maleate (0.4 mg), spastic obstruction of the right coronary artery was observed. He was treated successfully with nifedipine, and during 4 months of follow-up, he has had no symptoms. Because of the diagnostic interest in this type of angina in a young person, the literature on Prinzmetal's angina has also been reviewed.
