BACKGROUND: Revascularization of ischemic cardiomyopathy by coronary artery bypass grafting has been shown to improve survival among patients with left ventricular ejection fraction (LVEF) ≤35%, but the role of percutaneous coronary intervention (PCI) in this context is incompletely described. This study sought to evaluate the effect of PCI on mortality and hospitalization among patients with stable coronary artery disease and reduced left ventricular ejection fraction. METHODS: We performed a retrospective analysis comparing PCI with medical therapy among patients with ischemic cardiomyopathy in the Veterans Affairs Health Administration. Patients with angiographic evidence of 1 or more epicardial stenoses amenable to PCI and LVEF ≤35% were included in the analysis. Outcome data were determined by VA and non-VA data sources on mortality and hospital admission. RESULTS: From 2008 through 2015, a study sample of 4,628 patients was identified, of which 1,322 patients underwent ad hoc PCI. Patients were followed to a maximum of 3 years. Propensity score weighted landmark analysis was used to evaluate the primary and secondary outcomes. The primary outcome of all-cause mortality was significantly lower in the PCI cohort compared with medical therapy (21.6% vs 30.0%, P <.001). The secondary outcome of all-cause rehospitalization or death was also lower in the PCI cohort (76.5% vs 83.8%, P <.001). CONCLUSIONS: In this retrospective analysis of patients with ischemic cardiomyopathy with coronary artery disease amenable to PCI and LVEF ≤35%, revascularization by PCI was associated with decreased all-cause mortality and decreased all-cause death or rehospitalization.
