Objectives This study sought to report the 5-year outcomes of everolimus-eluting stents (EES) and paclitaxel-eluting stents (PES) in an all-comers population undergoing percutaneous coronary intervention (PCI). Background The medium-term 1 and 2-year results of the prospective randomized COMPARE trial (A Trial of Everolimus-Eluting Stents and Paclitaxel-Eluting Stents for Coronary Revascularization in Daily Practice) showed superior clinical outcomes with EES compared with PES in an all-comers PCI population. Whether this benefit is sustained over longer-term follow-up is unknown. Furthermore, systematic long-term follow-up data on these metallic drug eluting stents with durable polymers are scarce. Methods We randomly assigned 1,800 patients undergoing PCI to EES or PES. The pre-specified composite primary endpoint was death, myocardial infarction (MI), or target vessel revascularization (TVR). Results Follow-up at 5 years was completed in 1,791 (99.5%) patients. Treatment with EES compared with PES led to a relative risk reduction of the primary endpoint by 27% (18.4% vs. 25.1%, p = 0.0005), driven by lower rates of MI (7.0% vs. 11.5%, p = 0.001) and TVR (7.4% vs. 11.4%, p = 0.003), but not with mortality (9.0% vs. 10.3%, relative risk 0.88, p = 0.36). Moreover, patients treated with EES compared with PES had lower rates of definite/probable stent thrombosis at 5 years (3.1% vs. 5.9%, p = 0.005). The hazard curves for TVR, MI, and stent thrombosis diverge over the first 3 years and, subsequently, progress in parallel. Conclusions The early- and medium-term superiority of EES over PES measured both by safety and efficacy endpoints is sustained at 5 years in this all-comer population.
