Background: There are few data to compare the long-term efficacy of sirolimus-eluting stent (SES) and off-pump coronary artery bypass grafting (OPCAB) for diabetic patients with multivessel disease (MVD). Methods and Results: In a single-center non-randomized registry, 208 diabetic patients with MVD were examined (SES group: n=92, OPCAB group: n=116). The occurrence of major adverse cardiac and cerebrovascular events (MACCE, defined as all-cause death, non-fatal myocardial infarction, cerebrovascular event, and repeat revascularization) was compared between the 2 groups. Fasting blood glucose level, type of diabetic treatment and the prevalence of diabetic major vascular complications were similar between groups. The SES group had a significantly higher prevalence of 2-vessel disease and a significantly lower prevalence of 3-vessel disease compared with the OPCAB group. During the follow-up period (mean: 42±8 months), the rate of revascularization was significantly higher in the SES group than the OPCAB group (21% vs 6.9%, P=0.003). On the other hand, there was a significant higher occurrence of cerebrovascular events in the OPCAB group. Finally, the cumulative MACCE was similar between the 2 groups (27% vs 23%, P=0.492). Conclusions: At the 3-year clinical follow-up, the prevalence of MACCE in diabetic patients with MVD was comparable between the SES and the OPCAB groups.
