Abstract:

Background It is unknown whether contemporary drug-eluting stents have a similar safety profile in high bleeding risk patients treated with 1-month dual antiplatelet therapy following percutaneous coronary interventions. Methods and Results We performed an interventional, prospective, multicenter, single-arm trial, powered for noninferiority with respect to an objective performance criterion to evaluate the safety of percutaneous coronary interventions with Synergy bioresorbable-polymer everolimus-eluting stent followed by 1-month dual antiplatelet therapy in patients with high bleeding risk. In case of need for an oral anticoagulant, patients received an oral anticoagulant in addition to a P2Y₁₂ inhibitor for 1 month, followed by an oral anticoagulant only. The primary end point was the composite of cardiac death, myocardial infarction, or definite or probable stent thrombosis at 1-year follow-up. The study was prematurely interrupted because of slow recruitment. From April 2017 to October 2019, 443 patients (age, 74.8±9.2 years; women, 29.1%) at 10 Italian centers were included. The 1-year primary outcome occurred in 4.82% (95% CI, 3.17%-7.31%) of patients, meeting the noninferiority compared with the predefined objective performance criterion of 9.4% and the noninferiority margin of 3.85% (P_{noninferiority}<0.001) notwithstanding the lower-than-expected sample size. The rates of cardiac death, myocardial infarction, and definite or probable stent thrombosis were 1.88% (95% CI, 0.36%-2.50%), 3.42% (95% CI, 2.08%-5.62%), and 0.94% (95% CI, 0.35%-2.49%), respectively. Conclusions Among high bleeding risk patients undergoing percutaneous coronary interventions with the Synergy bioresorbable-polymer everolimus-eluting stent, a 1-month dual antiplatelet therapy regimen is safe, with low rates of ischemic and bleeding events.
