Objective: To assess long-term outcomes after percutaneous coronary intervention (PCI) with drug-eluting stent only compared with coronary artery bypass grafting (CABG) in patients with triple-vessel disease.
Background: Selection between PCI and CABG is still a clinically relevant issue in the management of patients with multi-vessel coronary artery disease.
Methods: Among 15,939 patients enrolled in the CREDO-Kyoto PCI/CABG registry/cohort-2, the current study population consisted of 2,193 patients who underwent elective multi-vessel coronary revascularization including left anterior descending coronary artery (LAD) either by PCI with sirolimus-eluting stent (SES) only (N = 945) or CABG (N = 1,248).
Results: The cumulative 5-year incidence of and the adjusted risk for the primary outcome measure (a composite of all-cause death, myocardial infarction [MI], or stroke) were not significantly different between PCI and CABG groups (22.6% vs. 23.0%, p = .40, and HR: 1.13, 95%CI: 0.91-1.40, p = .26). The risk of PCI relative to CABG for all-cause death and stroke was also insignificant (HR: 1.19, 95%CI: 0.92-1.53, p = .19; HR: 0.89, 95%CI: 0.62-1.27, p = .51). The adjusted 5-year risk for MI, hospitalization for heart failure (HF), any coronary revascularization and major bleeding was significantly different between the groups (HR: 1.59, 95%CI: 1.10-2.30, p = .01; HR: 1.49, 95%CI: 1.05-2.11, p = .02; HR: 3.70, 95%CI: 2.91-4.70, p < .0001; HR: 0.18, 95%CI: 0.14-0.22, p < .0001).
Conclusions: In patients who underwent coronary revascularization for multiple vessels including LAD, PCI using SES as compared with CABG was associated with a comparable 5-year risk for death/MI/stroke as well as for mortality, but with a markedly higher risk for any coronary revascularization.
