Survival in patients with myocardial infarction complicated by out-of-hospital cardiac arrest undergoing emergency percutaneous coronary intervention

Abstract Objectives We sought to evaluate the clinical outcomes of patients with myocardial infarction (MI) complicated by out-of-hospital cardiac arrest (OHCA) undergoing percutaneous coronary intervention (PCI). Background Controversy remains regarding the benefit of early PCI in patients with MI complicated by OHCA. Methods We analyzed the outcomes of 88 consecutive patients presenting with MI complicated by OHCA compared to 5101 patients with MI without OHCA who underwent PCI from the Melbourne Interventional Group registry between 2004 and 2009. Results Patients with OHCA had a higher proportion of ST-elevation MI presentations (90.9% vs. 50%, p Conclusion Patients with MI complicated by OHCA remain a high-risk group associated with high mortality. However, high procedural success rates similar to non-OHCA patients can be attained. Survival rates better than previously reported were observed with an emergent PCI approach, with 1-year survival comparable to a non-OHCA cohort if patients survive to hospital discharge.
