Intra-aortic balloon counterpulsation improves survival in cardiogenic shock complicating acute myocardial infarction.
The impact of intra-aortic balloon counterpulsation (IABC) on survival of patients with acute myocardial infarction (AMI) complicated by cardiogenic shock (CS) has been evaluated in this study of 85 patients. IABC was available for the 24 group A patients (and used in 20 patients). IABC was not available for the 21 group B patients who presented simultaneously with similar clinical characteristics and received identical pharmacological treatment. In-hospital and one year survival was significantly higher in group A (46% and 38% vs 19% and 10%, P < 0.001). Sixteen out of the 20 (group A1) IABC patients received early coronary revascularization. During 1980-1984, 35 patients with AMI and CS received IABC (group C) but none underwent early revascularization. There was no difference in in-hospital or one-year survival between group A1 (50% and 40%) and group C (45% and 40%). We conclude that early IABC improves survival of patients with AMI complicated by CS.
