Abstract

Objectives: The aim of this study was to compare in-hospital outcomes and long-term mortality of multivessel versus culprit vessel–only percutaneous coronary intervention (PCI) in patients with non–ST-segment elevation myocardial infarction (NSTEMI), multivessel disease (MVD) and cardiogenic shock. Background: The clinical benefits of complete revascularization in patients with NSTEMI, MVD, and cardiogenic shock remain uncertain. Methods: Among 25,324 patients included in the National Cardiovascular Data Registry CathPCI Registry from July 2009 to March 2018, the rates of in-hospital procedural outcomes were compared between those undergoing multivessel PCI and those undergoing culprit vessel–only PCI after 1:1 propensity score matching. Among patients aged ≥65 years matched to the Centers for Medicare and Medicaid Services database, long-term mortality was compared using proportional hazards analysis. Results: Multivessel PCI was performed in 9,791 patients (38.7%), which increased from 32.2% in 2010 to 44.2% in 2017 (p for trend <0.001). After 1:1 propensity matching (n = 7,864 in each group), those undergoing multivessel PCI had a 3.5% (95% confidence interval [CI]: 2.0% to 5.0%) lower absolute rate of in-hospital mortality (30.9% vs. 34.4%; p < 0.001; odds ratio [OR]: 0.85; 95% CI: 0.80 to 0.91), but a higher risk for bleeding (13.2% vs. 10.8%; p < 0.001; OR: 1.26; 95% CI: 1.15 to 1.40) and new requirement for dialysis (5.7% vs. 4.6%; p = 0.001; OR: 1.26; 95% CI: 1.10 to 1.46). Among those surviving to discharge, all-cause mortality was similar through 7 years (conditional hazard ratio: 0.95; 95% CI: 0.87 to 1.03; p = 0.20). Conclusions: Nearly 40% of patients with NSTEMI with MVD and cardiogenic shock underwent multivessel PCI, which was associated with lower in-hospital mortality but greater peri-procedural complications. Among those surviving to discharge, multivessel PCI did not confer additional long-term mortality benefit.
