Background—Long-term comparative data of first-generation drug-eluting stents are scarce. We investigated clinical and angiographic outcomes of sirolimus-eluting (SES) and paclitaxel-eluting stents (PES) at 5 years as part of the Sirolimus-Eluting Versus Paclitaxel-Eluting Stents for Coronary Revascularization (SIRTAX) LATE study. Methods and Results—A total of 1012 patients were randomly assigned to SES or PES. Repeat angiography was completed in 444 of 1012 patients (43.8%) at 5 years. Major adverse cardiac events occurred in 19.7% of SES- and 21.4% of PES-treated patients (hazard ratio, 0.89; 95% confidence interval, 0.68 to 1.17; P=0.39) at 5 years. There were no differences between SES and PES in terms of cardiac death (5.8% versus 5.7%; P=0.35), myocardial infarction (6.6% versus 6.9%; P=0.51), and target lesion revascularization (13.1% versus 15.1%; P=0.29). Between 1 and 5 years, the annual rate of target lesion revascularization was 2.0% (95% confidence interval, 1.4% to 2.6%) for SES and 1.4% (95% confidence interval, 0.9% to 2.0%) for PES. Among patients undergoing paired angiography at 8 months and 5 years, delayed lumen loss amounted to 0.37±0.73 mm for SES and 0.29±0.59 mm for PES (P=0.32). The overall rate of definite stent thrombosis was 4.6% for SES and 4.1% for PES (P=0.74), and very late definite stent thrombosis occurred at an annual rate of 0.65% (95% confidence interval, 0.40% to 0.90%). Conclusions—Long-term follow-up of first-generation drug-eluting stents shows no significant differences in clinical and angiographic outcomes between SES and PES. The continuous increase in late lumen loss in conjunction with the ongoing risk of very late stent thrombosis suggests that vascular healing remains incomplete up to 5 years after implantation of first-generation drug-eluting stents.
