Objectives: The aim of this study was to determine predictors and outcomes associated with staged percutaneous coronary intervention (PCI) versus one-time multivessel revascularization (OTMVR) in patients with multivessel coronary artery disease. Background: Prior observational studies have not evaluated predictors and outcomes of staged PCI versus OTMVR in a heterogenous population of patients with multivessel coronary artery disease who undergo multivessel revascularization. Methods: Data from the Veterans Affairs (VA) CART (Clinical Assessment, Reporting, and Tracking) Program were used to evaluate patients who underwent PCI of >2 vessels between October 1, 2007, and September 3, 2014. Associations between individual factors and the decision to perform staged PCI were assessed. Additionally, the impact of measured patient and procedural factors, site factors, and unmeasured site factors on the decision to perform staged PCI was compared. Cox proportional hazards models were used to determine the association between staged PCI and mortality. Results: A total of 7,599 patients at 61 sites were included. The decision to perform staged PCI was driven by procedural characteristics and unmeasured site factors. Staged PCI was associated with lower risk-adjusted mortality compared with OTMVR (adjusted hazard ratio [HR]: 0.78; 95% confidence interval [CI]: 0.72 to 0.84; p < 0.01). This mortality benefit was observed among the ST-segment elevation myocardial infarction (HR: 0.31; 95% CI: 0.21 to 0.47; p < 0.01), non–ST-segment elevation myocardial infarction (HR: 0.74; 95% CI: 0.64 to 0.87; p < 0.01), unstable angina (HR: 0.75; 95% CI: 0.64 to 0.89; p < 0.01) and stable angina (HR: 0.88; 95% CI: 0.77 to 1.00; p = 0.05) groups. Conclusions: The decision to pursue staged PCI was driven by procedural characteristics and unmeasured site variation and was associated with lower mortality compared with OTMVR. After adjustment, there was an association between staged PCI and reduced mortality. Given the observational nature of these findings, a randomized trial comparing the 2 is needed to guide practice.
