Abstract
Seven patients had recurrent pain of myocardial ischemia and impending extension in the recovery phase of acute myocardial infarction. Six had institution of intraaortic balloon pump assistance (IABPA) with subsequent coronary arteriography, and all underwent revascularization. Two patients were in cardiogenic shock (CS), 3 had varying degrees of impairment in left ventricular function, and the remaining 2 were hemodynamically stable. The IABPA interrupted ischemic pain in all patients. Pain recurred in 4 with temporary interruption of IABPA. From one to three vein bypass grafts were constructed in each patient, and in 1 patient, infarctectomy also was carried out. Six of 7 patients recovered and are well. Temporary circulatory assistance with IABP, urgent coronary arteriography, and revascularization was shown to be effective therapy for postinfarction patients with impending extension.
