Encouraging direction, but not yet definitive.
This meta-analysis of observational cohort studies found that GLP-1RA therapy is associated with a statistically significant 26% lower hazard of atrial fibrillation recurrence after catheter ablation. However, the evidence derives exclusively from observational studies with low certainty by GRADE assessment, and the authors explicitly state that randomized controlled trials are needed to confirm causality.
Systematic review and meta-analysis of cohort studies (3 prospective, 3 retrospective). Adults with atrial fibrillation undergoing catheter ablation, comparing GLP-1RA users to control groups. Mean age approximately 64 years in both arms.. Intervention: Glucagon-like peptide-1 receptor agonist (GLP-1RA) therapy. Compared with: Control group (no GLP-1RA therapy); comparator definitions varied by individual study. n = 14,278. Not specified.
GLP-1RA therapy associated with HR = 0.74 (95% CI 0.63–0.87) for AF recurrence compared to controls Six cohort studies pooled: 7,065 GLP-1RA users and 7,213 control participants Follow-up duration 12 to 24 months across studies
Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
While the association between GLP-1RA therapy and lower AF recurrence is statistically significant and directionally consistent, clinicians should recognize that this evidence is observational and subject to confounding. The authors explicitly recommend awaiting randomized controlled trials before treating this finding as causal or practice-guiding.
Meta-analysis of six observational cohort studies showing a statistically significant 26% lower hazard of AF recurrence with GLP-1RA therapy, but low certainty of evidence and lack of randomized data limit strength.

Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia worldwide, with a rising global prevalence. Post-ablation AF recurrence remains frequent, particularly among patients with obesity and metabolic syndrome. Glucagon-like peptide-1 receptor agonists (GLP-1RAs) have demonstrated favorable cardiometabolic and cardiovascular effects, but their association with AF recurrence after ablation remains uncertain. PubMed, Scopus, Embase, and Web of Science were searched through June 18, 2026. Cohort studies evaluating GLP-1RA therapy in adults with atrial fibrillation undergoing catheter ablation were included. The primary outcome was post-ablation atrial fibrillation recurrence (or recurrent atrial tachyarrhythmia, as defined by the individual studies). Adjusted hazard ratios (HRs) with 95% confidence intervals (CIs) were pooled using a random-effects model. Risk of bias was assessed using the JBI tool, and certainty of evidence was evaluated using the GRADE approach. Six cohort studies (three prospective and three retrospective), comprising 14,278 patients (7,065 GLP-1RA users and 7,213 controls), met the inclusion criteria. Follow-up duration ranged from 12 to 24 months across studies. The pooled mean age was approximately 64 years in both the GLP-1RA and control groups. GLP-1RA therapy was associated with a lower hazard of AF recurrence compared with the respective comparator groups (HR = 0.74, 95% CI 0.63–0.87; I² = 50.5%). However, the certainty of the evidence was low because the findings were derived predominantly from observational studies. Observational evidence suggests that GLP-1RA use is associated with a lower hazard of AF recurrence following catheter ablation. However, these findings should be interpreted cautiously, and further high-quality randomized controlled trials are required to confirm this association.
