Application of the Academic Research Consortium High Bleeding Risk criteria in patients treated with coronary bioresorbable polymer everolimus-eluting stents: Insights from the POEM trial

Abstract

BackgroundPrevious studies have investigated a 1 to 6-month short dual antiplatelet therapy (S-DAPT) after percutaneous coronary intervention (PCI) with modern drug eluting-stents to reduce bleeding events. ObjectivesTo investigate cardiovascular outcomes in patients at high bleeding risk (HBR) according to the Academic Research Consortium for High Bleeding Risk (ARC-HBR) criteria after PCI with the Synergy bioresorbable-polymer everolimus-eluting stents (EES). MethodsWe applied ARC-HBR criteria in the population of the prospective, single-arm, multicenter POEM (Performance of Bioresorbable Polymer-Coated Everolimus-Eluting Synergy Stent in Patients at HBR Undergoing Percutaneous Coronary Revascularization Followed by 1-Month Dual Antiplatelet Therapy) trial. The primary endpoint was a composite of cardiac death, myocardial infarction, or definite or probable stent thrombosis at 12 months. ResultsThe original POEM cohort included 356 patients (80.4 %) fulfilling ARC-HBR criteria. Oral anticoagulant (OAC) usage and age ≥75 years were the most frequent major and minor ARC-HBR criteria, respectively. The ARC-HBR group was mainly represented by men (71.1 %), with 74.4 ± 9.3 years and a high burden of cardiovascular risk factors. DAPT was prescribed in 79.3 %, and single antiplatelet (SAPT) with OAC in 18.7 %. 12-month follow-up was completed in 96.2 %. The primary endpoint occurred in 5.2 % (95 % CI 3.29–8.10) of patients, whereas bleeding Academic Research Consortium type 3–5 occurred in 2.7 % (95 % CI, 1.39 %–5.05 %). ConclusionPrevious results of the POEM trial showed positive outcomes regarding ischemic and bleeding events with an S-DAPT regimen after Synergy EES. These results are also confirmed in sub-group analysis when ARC-HBR criteria are applied.
