Abstract

Aims: To assess the safety and performance of the XIENCE V everolimus-eluting stent (EES) versus the TAXUS paclitaxel-eluting stent (PES) in the treatment of patients with de novo coronary artery lesions after a five-year follow-up period. Second-generation drug-eluting stents (DES) were developed with the aim of improving the safety profile of DES, after reports of stent thrombosis (ST) with first-generation devices. However, long-term follow-up data are scarce. Methods and results: SPIRIT II was a multicentre, prospective, single-blind, clinical trial, randomising 300 patients with up to two de novo coronary artery lesions in a ratio of 3:1 to either a EES or a PES. The five-year clinical follow-up was completed in 244 patients (81%). At five-year follow-up, 19.5% of patients were on thienopyridine in the EES arm, while 30.5% were on the same therapy in the PES arm. Cardiac mortality was significantly lower in EES than in PES (1.5% vs. 7.3%, p=0.015). Conclusions: Five-year clinical follow-up of the SPIRIT II trial demonstrated the continuing long-term safety and efficacy of EES. (Clinical trials government number: NCT00180310)
