Dual Antiplatelet Therapy in the Anticoagulated Patient Undergoing Percutaneous Coronary Intervention Risks, Benefits, and Unanswered Questions

摘要

A commonly encountered scenario is the patient with atrial fibrillation (AF) on oral anticoagulation (OAC) who either develops an acute coronary syndrome or has to undergo percutaneous coronary intervention with stent placement. In such patients, separate indications suggest combining OAC and dual antiplatelet therapy (DAPT). This approach, however, increases the risk of bleeding as well as thromboembolic risk if bleeding does not occur. For optimal clinical results, the risks and benefits of all possible treatment options should be determined based on the best available data. This review provides an overview of the most recent data regarding the optimal treatment of AF patients with an indication for combined treatment with OAC and DAPT.
