Objectives: To present data from the cohort of patients in the all‐comers Endeavor zotarolimus‐eluting stent (ZES) registry (E‐Five) who underwent 2‐year follow‐up. Background: The Endeavor ZES has been shown to be safe and efficacious for treatment of single, de novo lesions in patients with stable coronary artery disease. E‐Five evaluated the ZES in over 8,000 real‐world patients, at 188 sites followed to 1 year. A subset of sites continued follow‐up through 2 years to evaluate late‐term safety and effectiveness of the ZES in this population with diverse clinical and lesion characteristics. Methods: E‐Five, a prospective, multicenter, nonrandomized global registry, collected 2‐year outcomes for 2,116 patients from 26 centers. Sites were selected for participation based on patient accrual rates and the ability to continue follow‐up activities for an additional year. Complete data was available for 2,054 patients. To observe whether or not a sustained benefit was achieved, data for all patients from the selected sites were included in the analysis. Results: The outcomes in the 2‐year cohort tracked with the results of randomized controlled trials using the Endeavor ZES. One year results were MACE 7.5%, TLR 4.5%, and ARC definite/probable stent thrombosis 0.6%. Outcomes at 2 years for MACE, TLR, and ARC definite/probable stent thrombosis were 8.5, 5.1, and 0.7%, respectively. Conclusions: Long‐term efficacy and safety outcomes were maintained between 1 and 2 years for the 2‐year patient cohort, with only a small number of additional MACE, TLR, and very late stent thrombosis events. © 2010 Wiley‐Liss, Inc.
