Purpose: Limited data are available on the role of percutaneous cardiopulmonary support (PCPS) for the treatment of acute myocardial infarction (AMI) patients with cardiogenic shock. We investigated the clinical outcomes and predictors of in-hospitalmortality after PCPS in patients with AMI complicated by severe refractory cardiogenicshock. Materials and Methods: From January 2004 to December 2011, we analyzed data from 96 consecutive AMI patients with cardiogenic shock assisted by a PCPS system. The primary outcome was in-hospital mortality. The predictors of in-hospital mortality were determined by a Cox proportional-hazards model. Results:In-hospital mortality occurred in 51 (53.1%) patients and 58 (60.4%) patients were able to be weaned from PCPS. Cardiopulmonary resuscitation (CPR) was performedin 61 (63.5%) patients before PCPS initiation. On multivariate analysis, age ≥67 years [adjusted hazard ratio (HR), 4.74; 95% confidence interval (CI), 2.27--9.93; p<0.001], CPR (adjusted HR, 2.32; 95% CI, 1.11--4.85; p=0.03), lactate clearancefor 48 hours <70% (adjusted HR, 2.50; 95% CI, 1.04--6.05; p=0.041), and unsuccessfulrevascularization (adjusted HR, 3.57; 95% CI, 1.85--6.90; p=0.002) were independent predictors of in-hospital mortality after PCPS in patients with AMI complicated by cardiogenic shock. Conclusion: In spite of PCPS management, AMI patients complicated by severe refractory cardiogenic shock demonstrated high mortality. Older age, CPR, lower lactate clearance for 48 hours, and unsuccessful revascularizationwere independent predictors of in-hospital mortality.
