• Objectives and Background: First generation drug‐eluting stents have shown differential efficacy in high‐risk patient subsets at one year. It is unclear whether these differences endure over the medium‐ to long‐term. We compared the five‐year clinical efficacy and safety of sirolimus‐eluting stents (SES) and paclitaxel‐eluting stents (PES) in a population of high‐risk patients. Methods: The patient cohorts of the ISAR‐DESIRE, ISAR‐DIABETES, and ISAR‐SMART‐3 randomized trials were followed up for five years and data were pooled. The primary efficacy endpoint of the analysis was the need for target lesion revascularization (TLR) during a five‐year follow‐up period. The primary safety endpoint was the combination of death or myocardial infarction (MI) after five years. Results: A total of 810 patients (405 patients in the SES group and 405 patients in the PES group) was included. Over five years TLR was reduced by 39% with SES compared with PES stent (hazard ratio [HR] 0.61; 95% confidence interval [CI] 0.44–0.85; P = 0.004). No difference was observed according to death or MI rates between the two groups (HR 1.10; 95% CI 0.80–1.50; P = 0.57). Definite stent thrombosis occurred in 0.2% (n = 1) in the SES group and in 1.6% (n = 6) in the PES group (HR 0.16; 95% CI 0.02–1.34; P = 0.12). Conclusions: In high‐risk patient subsets the lower rate of 12‐month TLR observed with SES in comparison PES is maintained out to five years. In terms of safety, although there was no difference in the overall incidence of death or MI, there was a trend towards more frequent stent thromboses with PES. © 2011 Wiley‐Liss, Inc.
