Clopidogrel vs. Aspirin in Double Antithrombotic Therapy for Patients on Oral Anticoagulation Undergoing Coronary Stenting
Abstract
Over the past two decades, the combined use of long-term anticoagulation and antiplatelet therapy following percutaneous coronary intervention has been extensively investigated. Efforts to define an optimal antithrombotic strategy-balancing protection against thrombotic and thromboembolic events with minimization of bleeding risk-have led to the design and conduct of randomized clinical trials. This narrative review synthesizes the main evidence comparing different antithrombotic approaches in this setting, with particular focus on regimens stratified by oral anticoagulant type and on the direct comparison between aspirin- and clopidogrel-based double antithrombotic therapy, as evaluated in a limited number of recent studies. Further large-scale randomized data comparing these two regimens are needed to strengthen the current evidence and clarify this issue, as well as to evaluate the role of platelet function and/or genetic testing in guiding the selection of the optimal antiplatelet agent.
