Objectives: This paper reports the 3-year clinical outcomes of the XIENCE V (Abbott Vascular, Santa Clara, California) everolimus-eluting stent (EES) compared with the TAXUS (Boston Scientific, Natick, Massachusetts) paclitaxel-eluting stent (PES) in the randomized SPIRIT II (Clinical Evaluation of the Xience V Everolimus Eluting Coronary Stent System in the Treatment of Patients with de novo Native Coronary Artery Lesions) study. Background: The Xience V EES is a new-generation drug-eluting stent (DES) that might offer advantages over the first-generation DES in terms of improved clinical outcomes and a better safety profile. Methods: The SPIRIT II trial was a multicenter, prospective, randomized, single-blind, clinical trial, randomizing 300 patients with de novo coronary artery lesions in a ratio of 3:1 to either EES or PES. The primary end point was in-stent late loss at 180 days. Results: At 3-year clinical follow-up cardiac death was numerically lower with EES than PES (0.5% vs. 4.3%, p = 0.056). The observed rate of myocardial infarction was 3.6% for EES and 7.2% for PES (p = 0.31). The rate of ischemia-driven target lesion revascularization was 4.6% and 10.1% for EES and PES, respectively (p = 0.14). Overall, there was a trend for lower major adverse cardiovascular events in the EES group compared with PES (7.2% vs. 15.9%, p = 0.053). The rate of stent thrombosis was low and comparable in both groups (EES 1.0% vs. PES 2.9%). Conclusions: The present study reports the favorable 3-year clinical outcomes of the EES, which are consistent with the results from other studies of the EES with shorter follow-up.
