Background: The DUTCH PEERS (TWENTE II) trial ( NCT01331707) is a randomised, multicenter, single-blinded, investigator initiated all-comers trial. All coronary syndromes were permitted with no limit for lesion length, reference size, or number of lesions or diseased vessels to be treated. In total, 1811 patients were 1:1 randomised to cobalt chromium-based zotarolimuseluting stents (ZES) versus platinum chromium-based everolimus-eluting stents (EES). These durable polymer-based drug-eluting stents (DES) were developed to facilitate device deliverability and to improve stent apposition to the vessel wall. Purpose: We assessed the 4-year clinical outcome of the DUTCH PEERS trial in terms of safety and efficacy. Methods: Clinical outcome was assessed by means of follow-up data of the trial participants. The primary endpoint target vessel failure (TVF) is a composite of cardiac death, target vessel-related myocardial infarction (MI) or target vessel revascularization. Secondary endpoints included the individual components of the TVF and the incidence of definite-or-probable stent thrombosis. Endpoints were analyzed by the logrank test by comparing the time to the endpoint, using the Kaplan-Meier method. Independent contract research organizations performed the study monitoring and clinical event adjudication. Results: The 4-year clinical follow-up data were available in 1802 patients (99.5%; 4 patients were lost to follow-up and 5 withdrew consent). The ZES and EES groups showed favourable outcomes with a similar incidence of TVF (12.1% vs. 12.1%; Logrank p=0.95). The rates of the individual components of TVF were also similar for both stent arms: cardiac death (3.9% vs. 3.7%; Logrank p=0.78); target vessel-related MI (3.2% vs. 2.5%; Logrank p=0.38); and target vessel revascularization (6.8% vs. 7.5%; Logrank p=0.55), respectively. In addition, the incidence of definite-or-probable stent thrombosis was similar for patients treated with ZES versus EES (1.5% vs. 1.2%; Logrank p=0.67). Conclusion: At 4-year follow-up, ZES and EES showed similar and sustained results in terms of safety and efficacy for treating all-comer patients.
