OBJECTIVES: The pivotal TAXUS IV (TAXUS IV-SR: Treatment of De Novo Coronary Disease Using a Single Paclitaxel-Eluting Stent) trial evaluated the long-term safety and effectiveness of the paclitaxel-eluting stent (PES) compared with an otherwise identical bare-metal stent (BMS) in a relatively uncomplicated population of patients with a single de novo lesion in a native coronary vessel, treated between March and July 2002. BACKGROUND: Long-term follow-up is required to determine whether the early safety and efficacy of drug-eluting stents are maintained. METHODS: The primary end point of this prospective, randomized, double-blind trial was 9-month ischemia-driven target vessel revascularization (TVR) for PES versus the BMS control. Follow-up was complete in 1,230 (95.1%) of 1,294 randomized evaluable patients at 5 years. RESULTS: Compared with BMS, PES significantly reduced TVR at 9 months (12.1% vs. 4.7%; p < 0.0001); this benefit was maintained through 5 years (27.4% vs. 16.9%; p < 0.0001), given comparable TVR rates for BMS and PES between years 1 and 5 (4.1%/year vs. 3.3%/year; respectively, p = 0.16). Similar patterns were observed for composite major adverse cardiac events (MACE) (32.8% BMS vs. 24.0% PES, p = 0.0001 at 5 years). Stent thrombosis was comparable for PES and BMS at 9 months (0.8% BMS vs. 0.8% PES; p = 0.98) and at 5 years (2.1% BMS vs. 2.2% PES, p = 0.87). The overall revascularization benefits of PES were consistent across multiple subgroups, including sex, diabetes, left anterior descending artery lesion location, reference vessel diameter, lesion length, and multiple stents. CONCLUSIONS: These 5-year results demonstrate the long-term safety and sustained efficacy of PES compared with BMS in patients with noncomplex lesions.
