Antiplatelet Therapy and Cardiovascular Diseases

Because a delayed arterial healing response after drug-eluting stent implantation has raised concerns about safety in diabetic patients, long-term effects of treatment with sirolimus-eluting stent (SES), as compared with bare-metal stent (BMS), have to be established. The aim of the 5-year follow-up of the randomized, controlled, open-label multicenter SCORPIUS study was to assess long-term safety and efficacy of the CYPHER (Cordis, Johnson & Johnson, Bridgewater, NJ) SES in percutaneous coronary intervention of diabetic patients. A total of 190 patients with type 2 diabetes mellitus were randomized to receive either a SES (n = 95) or a BMS (n = 95). Dual-antiplatelet therapy (aspirin plus clopidogrel) was prescribed for at least 6 months. Clinical follow-up data were scheduled at 1, 8, and 12 months and 5 years. Treatment with SES resulted in a 16% decrease in the rate of major adverse cardiac events (36% vs 52%; hazard ratio 0.6, 95% CI 0.4-0.9; P = .02). This reduction in major adverse cardiac events with SES at 5 years was mostly attributable to a lower number of repeat target lesion revascularization (13% vs 29%; hazard ratio 0.4, 95% CI 0.2-0.7; P = .003). No differences between groups were observed for safety end points (all-cause mortality 21% vs 21%, cardiac death 15% vs 13%, repeat myocardial infarction 8% vs 9%, and stent thrombosis 5% vs 6%) at 5 years. The 5-year follow-up of the SCORPIUS trial demonstrates the long-term antirestenotic efficacy of SES in diabetic patients with significantly reduced target lesion revascularization and comparable rates of mortality, myocardial infarction, and stent thrombosis compared with BMS.
