Aspirin given for up to 2 years after initial anticoagulant treatment reduces the risk of venous thromboembolism recurrence without increasing risk of major bleeding

摘要

The use of aspirin to prevent recurrent venous thromboembolism (VTE) after a first idiopathic event should not currently become a standard practice. Further studies are required before the use of aspirin following anticoagulation with warfarin for a first episode of venous thromboembolism becomes adopted as routine clinical practice. A direct comparison between low-dose aspirin and standard intensity warfarin is required.
