Objectives The aim of this study was to evaluate the relative efficacy and safety of zotarolimus-eluting stents (ZES) in comparison with the established and widely used sirolimus- (SES) and paclitaxel-eluting stents (PES) in routine clinical practice. Background Whether ZES might provide similar clinical and angiographic outcomes in a broad spectrum of patients compared with SES or PES is undetermined. Methods We performed a single-blind, multicenter, prospectively randomized trial to compare ZES with SES and PES in 2,645 patients undergoing percutaneous coronary intervention. The primary end point was a composite of major adverse cardiac events (MACE) (death, myocardial infarction, and ischemia-driven target vessel revascularization) at 12 months. A noninferiority comparison (ZES vs. SES) and a superiority comparison (ZES vs. PES) were performed for the primary end point. Results Baseline clinical and angiographic characteristics were similar in the 3 groups. At 12 months, the ZES group showed noninferior rates of MACE compared with the SES group (10.2% vs. 8.3%, p for noninferiority = 0.01, p for superiority = 0.17) and significantly fewer MACE than the PES group (10.2% vs. 14.1%, p for superiority = 0.01). The incidence of death or myocardial infarction was similar among the groups (ZES vs. SES vs. PES, 5.8% vs. 6.9% vs. 7.6%, respectively, p = 0.31). The incidence of stent thrombosis was significantly lower in the SES group (ZES vs. SES vs. PES, 0.7% vs. 0% vs. 0.8%, respectively, p = 0.02). Conclusions In this large-scale, practical randomized trial, the use of ZES resulted in similar rates of MACE compared with SES and in fewer MACE compared with PES at 12 months.
