title: The role of coronary artery spasm in anginal syndromes.
abstract: The role of coronary artery spasm in the production of angina at rest is emphasized. Three case reports of variant angina are presented to illustrate the spectrum of presentation and to stress the principles underlying the therapy of coronary artery spasm. This entity should be suspected and diagnosed more frequently in order that patients may derive the benefit of relatively specific therapy which consists of calcium antagonists and long-acting nitrates.
