title: Variant angina pectoris: a clinical and coronary arteriographic spectrum.
abstract: The clinical course and coronary arteriographic findings in eight patients with Prinzmetal's variant angina pectoris are reviewed and contrasted to previously reported cases.  In six patients with S-T-elevation inferiorly, three had normal coronary arteriograms, one had complete right coronary artery occlusion, one had diffuse triple-vessel disease, and one did not undergo coronary arteriography.  In two patients with S-T-elevation anteriorly, severe stenosis of the anterior descending coronary artery was present.  Medical treatment in four patients and surgical revascularization of the anterior descending coronary artery in two patients were both accompanied by marked symptomatic improvement.  Spontaneous loss of angina occurred in two patients.  During 17 months' mean follow-up, seven patients have remained free of angina and one died suddenly.  Variant angina pectoris may be accompanied by a variety of coronary arteriographic findings and the prognosis appears more favorable than previously reported.
