Should we add antiplatelet agents to current deep venous thrombosis treatments? A Cochrane Review summary with commentary

BACKGROUND: Venous thromboembolism (VTE) is an important complication in rehabilitation practice despite preventive measures. The management can be complicated because patients may have co-existing cardiovascular comorbidities. OBJECTIVE: To assess the effects of antiplatelet agents in addition to current best medical practice (BMP) compared to current BMP (with or without placebo) for the treatment of deep venous thrombosis (DVT).METHODS: A summary of the Cochrane Review by Flumignan et al. (2022), with comments from a rehabilitation perspective.RESULTS: The review included six studies with 1625 eligible participants, with data up to 37.2 months of follow-up. When used after standard initial treatment with anticoagulants, antiplatelet agents such as aspirin in addition to BMP, may reduce recurrence of DVT or pulmonary embolism, when compared to BMP plus placebo in a chronic DVT setting and there may be a lower risk for post-thrombotic syndrome in patients with acute DVT. There is no clear difference in side effects, major bleeding, or pulmonary embolism (PE) with the use of antiplatelet agents.CONCLUSION: Adding antiplatelet agents to standard anticoagulation treatment in patients with VTE could provide benefit without increasing risks in selected patient groups. However, high quality studies with a long-term follow up are needed, including patients in rehabilitation settings.
