Long-term survival of elderly patients undergoing percutaneous coronary intervention for myocardial infarction complicated by cardiogenic shock

Abstract Background The long-term benefit of early percutaneous coronary intervention (PCI) for cardiogenic shock (CS) in elderly patients remains unclear. We sought to assess the long-term survival of elderly patients (age ≥75years) with myocardial infarction (MI) complicated by CS undergoing PCI. Methods We analyzed baseline characteristics, early outcomes, and long-term survival in 421 consecutive patients presenting with MI and CS who underwent PCI from the Melbourne Interventional Group registry from 2004 to 2011. Mean follow-up of patients who survived to hospital discharge was 3.0±1.8years. Results Of the 421 consecutive patients, 122 patients were elderly (≥75years) and 299 patients were younger ( Conclusions Elderly patients with MI and CS have lower procedural success and higher in-hospital mortality compared to younger patients. However, comparable long-term survival can be achieved, especially in patients who survive to hospital discharge with the selective use of early revascularization.
