Abstract

Background: Mortality of patients with ST-segment elevation myocardial infarction (STEMI) with cardiogenic shock (CS) on admission remains high despite invasive treatment. The aim of this analysis was to assess the relationship between the infarct-related artery (IRA) and the early and 12-month outcomes of patients with STEMI and CS treated by percutaneous coronary intervention (PCI).<br />Methods: Two thousand ninety patients with STEMI and CS registered in the prospective Polish Registry of Acute Coronary Syndromes from October 2003 to November 2009 were included.<br />Results: The in-hospital mortality in the left main (LM), left anterior descending artery (LAD), circumflex artery (Cx), and right coronary artery (RCA) groups was 64.7%, 41.0%, 36.0%, and 30.8%, respectively, with p<0.0001. The 12-month mortality in the LM, LAD, Cx, and RCA groups was 77.7%, 58.2%, 55.1%, and 45.0%, respectively, with p<0.0001. After multivariate adjustment, LM as the IRA was significantly associated with higher 12-month mortality (hazard ratio=1.71, 95% confidence interval=1.28-2.27, p=0.0002).<br />Conclusions: In-hospital and long-term mortality of patients with STEMI and CS treated by PCI are significantly correlated to the IRA, being highest for LM and lowest for RCA.<br /> (Copyright © 2011 Elsevier Ireland Ltd.
