Treatment of post-myocardial infarction angina by intra-aortic ballon pumping and emergency revascularization.
Twenty-one patients with postinfarction angina (2 to 15 days after acute myocardial infarction) unresponsive to medical therapy were treated by intra-aortic balloon pumping (IABP). Anginal pain and electrocardiographic (ECG) ST-segment changes were prevented in all patients. Coronary angiograms were obtained during IABP without complication and confirmed severe coronary artery disease. Of the four nonoperated patients, three had reinfarction and two died of cardiogenic shock. Seventeen patients underwent aorta-coronary bypass grafting, associated with aneurysmectomy in two patients and closure of a ventricular septal defect in one. Sixteen patients survived the operation. All survivors are in clinically improved condition and 14 are pain free from 9 to 28 months postoperatively, but three have mild heart failure.
