1-month versus 12-month dual antithrombotic therapy after percutaneous coronary intervention in patients with atrial fibrillation (OPTIMA-AF): a multicentre, open-label, hybrid non-inferiority and superiority, randomised, controlled trial

Listen to this summary

The OPTIMA-AF trial aimed to determine whether 1-month dual antithrombotic therapy followed by direct oral anticoagulant (DOAC) monotherapy is as effective and safer than 12-month dual therapy in patients with atrial fibrillation undergoing percutaneous coronary intervention (PCI). The results indicated that the 1-month regimen was non-inferior in preventing death or thromboembolic events and significantly reduced the incidence of major or clinically relevant non-major bleeding, suggesting a favorable clinical profile for the shorter treatment duration.
