title: Coronary artery spasm and cardiac arrest in carcinoid heart disease.
abstract: Previously reported cardiac manifestations of carcinoid disease include right-sided valvular dysfunction and vasomotor disturbances. This report describes a 62-year-old white man who had electrocardiographically documented widespread elevation of the S-T segment, arrhythmias, and cardiac arrest after exercise. Noninvasive and laboratory studies confirmed the diagnosis of malignant carcinoid disease with tricuspid valve involvement. Coronary angiography revealed mild atherosclerosis. Thus, coronary artery spasm is a previously unrecognized manifestation of carcinoid heart disease and introduces what may be an important relationship of endogenous, excessive vasoactive amines to human coronary vasospasm.
