Introduction
Despite the technological advancements in catheter ablation strategies, the recurrence of atrial fibrillation (AF) post-ablation remains a concern that requires further investigation. Glucagon-like peptide 1 (GLP-1) receptor agonists have shown a significant effect on weight reduction, which in turn is associated with freedom from AF recurrence in both patients who are obese and not obese undergoing ablation. Therefore, we aimed to summarize the available evidence on the efficacy of GLP-1 receptor agonists in maintaining sinus rhythm post-ablation.
Methods
Medline, Cochrane Library, and Scopus were searched until June 9, 2024. Double-independent study selection, data extraction, and quality assessment were performed. Evidence was pooled using DerSimonian-Laird random effects meta-analysis.
Results
Three propensity score-matched studies (n = 6031 participants) were analyzed. Over a 12-months follow-up, the use of GLP-1 receptor agonists was associated with a significant reduction in AF recurrence compared to controls, hazard ratio (HR) = 0.549, 95% confidence interval (CI) = [0.315, 0.956], P = 0.034; I2 = 57%. No significant heterogeneity was observed (Q statistic = 4.6, heterogeneity P = 0.1).
Conclusion
The use of GLP-1 receptor agonists is associated with a lower risk of AF recurrence in patients receiving AF ablation therapy. Further large-scale randomized trials are necessary to explore the efficacy of GLP-1 receptor agonists in maintaining ablation outcomes over the long term.
