Managing Antithrombotic Therapy in Patients With Both Atrial Fibrillation and Coronary Heart Disease

Available clinical trials and registries provide remarkably little evidence to guide difficult clinical decision making in patients with combined AF and CHD. In patients on triple antithrombotic therapy with vitamin K antagonists, aspirin, and clopidogrel, a single clinical trial indicates that withdrawal of aspirin may reduce bleeding risk without increasing the risk of coronary thrombosis. It is unclear whether this evidence applies to combinations of NOACs and newer P2Y12 inhibitors. Clinical trials of combinations of the newer antithrombotic agents are urgently needed to guide clinical care.
