ObjectiveWe sought to compare the long-term outcomes of multiarterial graft (MAG) coronary artery bypass grafting (CABG) versus percutaneous coronary intervention (PCI) with second-generation drug-eluting stents (DES) to treat stable multivessel coronary artery disease.MethodsThis study was a multicenter population-based retrospective analysis of all residents of Ontario, Canada, from January 1, 2011, to December 31, 2019. We identified 3600 cases of elective primary isolated CABG with MAG and 2187 cases of PCI with second-generation DES.ResultsAfter the application of propensity score-weighting using overlap weights, MAG was associated with better survival over 5 years compared with DES (96.8% vs 94.5%; hazard ratio [HR], 0.56; 95% CI, 0.37-0.85). MAG was also associated with better secondary outcomes including a composite of death, myocardial infarction, and stroke (94.3% vs 88.5%; HR, 0.49; 95% CI, 0.36-0.65). The rate of death, stroke, myocardial infarction, and repeat revascularization (91.2% vs 70.7%; HR, 0.24; 95% CI, 0.20-0.30), and the individual end points of myocardial infarction (1.4% vs 6.9%; HR, 0.22; 95% CI, 0.13-0.35), and repeat revascularization (4.1% vs 24.2%; HR, 0.14; 95% CI, 0.10-0.18) were lower with MAG. PCI with second-generation DES was associated with a lower rate of stroke up to 5 years (0.6% vs 1.8%; HR, 3.97; 95% CI, 1.45-10.88).ConclusionsCABG with MAG was associated with better survival and fewer major cardiac adverse events compared with second-generation DES and might be considered the treatment of choice for patients with stable multivessel coronary artery disease. Further randomized controlled trials are needed to confirm this hypothesis.Copyright © 2021 The American Association for Thoracic Surgery. Published by Elsevier Inc. All rights reserved.
