Practical aspects of antithrombotic therapy in patients with atrial fibrillation and coronary artery disease

Abstract

Atrial fibrillation (AF) is the most common cardiac arrhythmia, which is associated with an increased risk of cardiovascular death. The latter is partly due to the common combination with coronary artery disease (CAD). If indicated, patients with AF need continuous direct oral anticoagulant therapy to prevent thromboembolic events. In addition, patients with CAD who require urgent or elective percutaneous coronary intervention require dual antiplatelet therapy. Therefore, physicians often face a dilemma when choosing the most appropriate antithrombotic therapy regimen for AF patients undergoing percutaneous coronary intervention. Integrating two medication approaches to treat a single patient with a combination of AF and CAD is challenging and must strike a balance between high efficacy and safety. This article provides an overview of studies on this issue.
