Glucagon-Like Peptide-1 Receptor Agonists and Risk of Venous Thromboembolism: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.
Review
Overview
abstract
BACKGROUND: Limited data exist on the association of glucagon-like peptide 1 receptor agonists (GLP-1RAs) with the risk of venous thromboembolism. This meta-analysis aimed to investigate the association between GLP-1RAs and the risk of venous thromboembolism including deep vein thrombosis (DVT) and pulmonary embolism. METHODS AND RESULTS: A systematic search of PubMed, Web of Science, EMBASE, and Cochrane library was conducted from inception until July 3, 2024, to identify randomized controlled trials comparing GLP-1RAs with placebo or other anti-iabetic drugs, with reported data on DVT and pulmonary embolism. The primary outcome was venous thromboembolism, and secondary outcomes included DVT and pulmonary embolism. Pooled odds ratios (ORs) were calculated using fixed-effects models with Mantel-Haenszel method and treatment arm continuity correction for zero-event trials. A total of 39 randomized controlled trials involving 70 499 participants were included. A nonsignificant upward trend in the risk of venous thromboembolism was observed among participants using GLP-1RAs (OR, 1.19 [95% CI, 0.94-1.50]). GLP-1RAs were significantly associated with an increased risk of DVT (OR, 1.64 [95% CI, 1.14-2.36]); risk difference 25 (5-52) more events per 10 000 person-years). Subgroup analyses revealed that increased risk of DVT was particularly prominent in randomized controlled trials with treatment duration >1.5 years (OR, 2.32 [95% CI, 1.49-3.60]) and in cardiovascular outcome trials (OR, 2.18 [95% CI, 1.36-3.49]). No significant association was observed between GLP-1RAs and risk of pulmonary embolism. CONCLUSIONS: GLP-1RAs might increase the risk of DVT, especially for long-term use of GLP-1RAs. Clinicians should be aware of this potential risk when prescribing GLP-1RAs.
