Aims: The aim of this study was to compare the 5-year outcomes of patients with multivessel disease (MVD) involving the proximal left anterior descending (LAD) artery who were treated with sirolimus drug-eluting stents (SES), bare metal stents (BMS) and coronary artery bypass surgery (CABG). Methods and results: Clinical outcomes were compared between the 682 patients enrolled in the ARTS-I and ARTS-II study who had MVD involving the proximal LAD, and were treated with BMS (27.4%), CABG (30.2%), and SES (42.4%). At 5-year follow-up the primary endpoint of major adverse cardiovascular and cerebrovascular events (MACCE) occurred in 33.7%, 18.0% and 24.9% of patients treated with BMS, CABG and SES, respectively (BMS vs. SES p=0.04, CABG vs. SES p=0.07). Unadjusted and adjusted rates of mortality and death/stroke/myocardial infarction (safety) were comparable between all three treatments. Repeat revascularisation was significantly lower following CABG irrespective of adjustment. The absolute difference in MACCE between patients with a logistic EuroSCORE above and below the mean (i.e., 2.09%) was 18.8% (p=0.001), and 1.9% (p=0.28) for CABG and SES, respectively. In patients with a high EuroSCORE, SES was a significantly safer treatment (p=0.04) whilst repeat revascularisation remained lower with CABG irrespective of the EuroSCORE. Conclusions: At 5-year follow-up CABG has comparable safety, and superior efficacy in terms of reducing repeat revascularisation compared to BMS and SES in the treatment of patients with MVD involving the proximal LAD however, appropriate patient selection remains imperative.
