OBJECTIVES: This study aimed to assess the efficacy of a rapamycin plus 17-beta-estradiol-eluting stent versus a rapamycin-eluting stent in patients with coronary artery disease. BACKGROUND: Estradiol promotes rapid re-endothelialization of coronary stents in animal models, but it is not known whether combining this drug with rapamycin represents an improved drug-eluting stent technology in terms of reduced lumen renarrowing. METHODS: In this randomized study, we enrolled 502 patients with de novo lesions in native coronary arteries who were randomly assigned to receive either a polymer-free, estradiol plus rapamycin-eluting stent (ERES) (n = 252) or a polymer-free, rapamycin-eluting stent (RES) (n = 250). The primary end point was in-stent late lumen loss in the follow-up angiography. Secondary end points were binary angiographic restenosis, target lesion revascularization, combined incidence of death and myocardial infarction, and incidence of stent thrombosis during 1 year after randomization. The study was designed to test for the superiority of the ERES compared with the RES with respect to in-stent late lumen loss. RESULTS: Late lumen loss (0.52 +/- 0.58 mm vs. 0.51 +/- 0.58 mm, p = 0.83), the incidence of binary angiographic restenosis (17.6% vs. 16.9%, p = 0.85), the incidence of target lesion revascularization (14.3% vs. 13.2%, p = 0.72), the combined incidence of death and myocardial infarction (7.9% vs. 8.0%, p = 0.98), and the incidence of stent thrombosis (0.8% vs. 1.2%, p = 0.99) were not significantly different between the ERES group and the RES group. CONCLUSIONS: No apparent beneficial effect is obtained by adding estradiol to a polymer-free rapamycin-eluting stent during the first year after the procedure.
