TCT-43 Impact Of Intraaortic Balloon Pump On 30-Day Mortality In Cardiogenic Shock AMI Patients With Unsuccessful And Successful Primary PCI - Analysis From PL-ACS Registry

Abstract

Background: Recently, usefulness of intraaortic balloon pump (IABP) for patients with acute myocardial infarction (AMI) and cardiogenic shock (CS) is questioned. Therefore we analysed influence of IABP in CS AMI patients with unsuccessful and successful primary PCI on 30-day mortality. Methods: We analysed 4211 patients with CS and AMI from nationwide PL-ACS registry. Unsuccessful PCI was defined as final TIMI flow grade 0 or 1. Results: Patients with unsuccessful PCI comprised 13.5% (table). In both unsuccessful and successful PCI groups 20% of patients had IABP support and these patients were of the higher risk profile. IABP was associated with lower 30-day mortality in unsuccessful PCI group while with higher in successful PCI group. After adjustment in multivariate Cox proportional model regression IABP remained significantly associated with reduction of 30-day mortality in patients with unsuccessful PCI (HR 1⁄4 0.71, 95%CI 1⁄4 0.55-0.91, p1⁄40.0065) and increased mortality in patients with successful PCI (HR 1⁄4 1.26, 95%CI 1⁄4 1.13-1.43, p<0.0001).
