Abstract：Objective To investigate the curative effect of early intra-aortic balloon pump (IABP) implantation on acute myocardial infarction (AMI) complicating cardiac shock (CS) in elderly patients.Methods The patients (aged over 65,n=116) were chosen from Jan. 2011 to Mar. 2014, and then divided, according to the duration from attack of CS to IABP implantation, into group A (n=53, duration≤3 h) and group B (n=63, duration>3 h). The revascularization and dopamine administration were observed, and the total IABP auxiliary time, all-cause mortality within 30 d, acute respiratory failure, acute renal failure and major bleeding events were recorded. Results There was no statistical difference in dopamine administration. The average IABP auxiliary time was shorter in group A than that in group B (71.0 hvs. 128.5 h,P<0.01). There was statistical difference in all-cause mortality between 2 groups (15.1%vs. 31.7%,P<0.05). The incidence of cardiac death (13.2%vs 25.4%,P=0.10), acute respiratory failure (26.4%vs. 34.9%,P=0.32), acute renal failure (11.3%vs 20.6%,P=0.18) and major bleeding events (5.7%vs. 11.1%,P=0.29) showed a decreasing trend but without statistical significance.Conclusion The early IABP implantation maybe improve survival rate within 30 d and reduce the incidence of major clinical events in elderly patients with AMI complicating CS.
