Guideline in Focus
Antithrombotic Therapy in COVID-19

Increasing evidence shows that the risk of thrombotic complications in COVID-19 is associated with a hypercoagulable state. This guideline provides recommendations for managing four arterial (pro)thrombotic medical conditions in patients with COVID-19 and assessing the risks and benefits of additional medication.

Key Recommendations

In hospitalized patients with COVID-19 and confirmed acute coronary syndrome (ACS), we recommend dual antiplatelet therapy to reduce the risk of recurrent ACS or death.

In outpatients with COVID-19 receiving antiplatelet therapy for a previous stroke, we suggest against the addition of or change to oral or subcutaneous anticoagulation.

In non-ICU hospitalized patients with COVID-19 on oral anticoagulation for atrial fibrillation (A-fib) who require discontinuation of oral anticoagulation, we suggest switching to therapeutic dose low molecular weight heparin or unfractionated heparin.
