We compared 10-year clinical outcomes in diabetes and nondiabetes patients treated with Endeavor zotarolimus-eluting (ZES) or Cypher sirolimus-eluting coronary stents (SES). A total of 1,162 patients were randomized to ZES (169 with diabetes) and 1,170 patients were randomized to SES (168 with diabetes). Patients were further stratified by diabetes status at the time of inclusion. A subgroup of patients with diabetes (n = 88) underwent angiographic re-evaluation 10 months after stent implantation. End points included a combined end point of death or myocardial infarction, and the individual end points of death, myocardial infarction, and revascularization. In patients with diabetes, we found no difference in the combined end point (odds ratio [OR] 0.81, 95% confidence interval [CI] 0.53 to 1.24), death (OR 0.80, 95% CI 0.51 to 1.25), or in MI (OR 1.07, 95% CI 0.60 to 1.91). However, diabetics with ZES more frequently underwent coronary revascularization compared with SES patients (OR 1.93, 95% CI 1.05 to 3.66). In patients without diabetes, ZES and SES had similar 10-year rates of all end points (death: OR 1.13, 95% CI 0.93 to 1.39; MI: OR 0.80, 95% CI 0.61 to 1.05; revascularization: OR 0.81, 95% CI 0.61 to 1.09). Landmark analysis from 5 to 10 years showed no difference in outcomes between SES and ZES in either subgroup. In conclusion, at 10 years, SES and ZES performed similarly in patients with and without diabetes. Although coronary revascularization was more prevalent in diabetes patients with ZES, this may, in part, have been related to the angiographic follow-up that was offered to a subgroup of diabetes patients.
