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.
