Background: Everolimus-eluting stents (EES) have equivalent short-term angiographic and clinical outcomes to sirolimus-eluting stents (SES), but EES may be superior to SES with regard to long-term clinical safety. We report the 3-year clinical outcomes of EES and SES from the prospective EXCELLENT Randomized Trial (NCT00698607). Methods and Results: We randomly assigned 1,443 patients undergoing percutaneous coronary intervention 3:1 to receive EES and SES, respectively. We investigated endpoints including target lesion failure (TLF) and individual clinical outcomes including stent thrombosis (ST) at 3 years. For EES and SES, the TLF rate was 4.82% and 4.12% (risk ratio [RR], 1.16, 95% CI: 0.65–2.06, P=0.62), respectively. Results were similar in other efficacy endpoints including target lesion revascularization. For safety endpoints, rate of all-cause death was significantly lower for EES (1.67%) than SES (3.57%; RR, 0.46; 95% CI: 0.23–0.94, P=0.03), while the incidence of cardiac death or myocardial infarction was numerically lower in EES. On 1-year landmark analysis, rates of all-cause death and major adverse cardiovascular events were significantly lower for EES than SES. Definite or probable ST was numerically 3-fold higher for SES (1.37%) compared with EES (0.46%). Conclusions: EES and SES had similar efficacy with regard to 3-year outcomes in the EXCELLENT trial, while delayed safety events all trended to favor EES.
