3-Year Clinical Outcomes After Implantation of Permanent-Polymer Versus Polymer-Free Stent: ReCre8 Landmark Analysis.

OBJECTIVES: The aim of this analysis was to assess long-term clinical outcomes of the polymer-free Amphilimus-eluting stent (PF-AES) compared with a latest generation permanent-polymer drug-eluting stent (DES) in an all-comers population. BACKGROUND: PF-AES possess multiple properties improving targeted drug elution without the presence of polymers. Evaluation of long-term clinical performance of PF-AES versus latest generation permanent-polymer DES has not yet been performed in a large randomized trial introducing shortened dual-antiplatelet therapy. METHODS: In this physician-initiated, multicenter, randomized, all-comers trial, patients undergoing percutaneous coronary intervention with implantation of DES were enrolled. Patients were stratified for diabetes and troponin status and randomized to implantation of a permanent-polymer zotarolimus-eluting stent (PP-ZES) or a PF-AES. Dual-antiplatelet therapy duration was 12 months in troponin-positive patients and 1 month in troponin-negative patients. A noninferiority analysis was conducted to compare the 2 arms regarding target lesion failure (TLF) between 1 and 3 years. RESULTS: A total of 1,491 patients were randomized and treated. In this landmark analysis, between 1- and 3-year follow-up, TLF occurred in 35 patients (4.9%) in the PP-ZES arm and 37 PF-AES patients (5.1%). Clinical noninferiority of the PF-AES was confirmed, with a risk difference of 0.2% (upper limit 1-sided 95% CI: 2.2%; Pnoninferiority = 0.0031). CONCLUSIONS: ReCre8 (Randomized "All-Comer" Evaluation of a Permanent Polymer Resolute Integrity Stent Versus a Polymer Free Cre8 Stent) is the first randomized, multicenter trial with a head-to-head comparison of PP-ZES compared with PF-AES to investigate clinical outcomes of these new-generation DES in an all-comers population with long-term follow-up. On the basis of the present results, PF-AES are clinically noninferior to PP-ZES regarding TLF between 1 and 3 years.
