The Effect of Antiplatelet Therapy on COVID-19

抄録

Platelets are one of the major targets of SARS-CoV-2. Activated platelets release prothrombotic substances, express adhesion molecules, and activate coagulation, thereby contributing to the thrombotic tendency in COVID-19. However, the antiplatelet therapy is not recommended in the current international guidelines. We think that the initiation timing and the target severity are the causes of the failure in clinical trials. As shown in the clinical studies that examined the effects of anticoagulants, early initiation in moderate severity is necessary for the success of antithrombotic therapy. Future trials are warranted to study the effects of antiplatelets in such conditions.
