For the acute treatment of venous thromboembolism, the direct oral anticoagulants (DOACs) have increasingly replaced injectable anticoagulant therapy followed by warfarin. For patients with an unprovoked deep vein thrombosis or pulmonary embolism who may benefit from long-term extended prophylaxis for the secondary prevention of VTE, the choice is less clear. Should a DOAC be used? If so, which one and what's the best dose? What about low-dose aspirin? Is extended therapy needed at all? The EINSTEIN CHOICE study adds important new insights to the growing body of literature.
