Abstract
Background: In the current international guidelines, intra-aortic balloon pump (IABP) counterpulsation is considered a class I treatment for acute myocardial infarction complicated by cardiogenic shock. However, evidence is based mainly on registry data, and there is a paucity of randomized clinical trials.Methods: Results: At 30 days, 119 patients in the IABP group (39.7%) and 123 patients in the control group (41.3%) had died (relative risk with IABP, 0.96; 95% confidence interval, 0.79 to 1.17; P = 0.69). There were no significant differences in secondary endpoints or in process-of-care measures, including the time to hemodynamic stabilization, the length of stay in the intensive care unit, serum lactate levels, the dose and duration of catecholamine therapy, and renal function.Conclusions: The use of IABP counterpulsation did not significantly reduce 30-day mortality in patients with acute myocardial infarction complicated by cardiogenic shock for whom an early revascularization strategy was planned. © 2013 BioMed Central Ltd.
