Abstract 4145802: Association between Glucagon-like peptide-1 receptor agonists and risk of Arrhythmias or Heart Failure among patients with Type 2 Diabetes: A Meta-Analysis of 29 Randomized Controlled Trials.

Background: Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) have shown a reduction in major adverse cardiovascular events (MACE) among patients with type 2 diabetes mellitus (T2DM). However, their effect on reducing the risk of incidence of arrhythmias and heart failure has not been established, and there is very limited literature to date. Objective: We evaluated the effect of GLP-1 RAs on the incidence of arrhythmias and heart failure among patients with T2DM. Methods: We performed a systematic review and meta-analysis of randomized controlled trials (RCTs) that enrolled patients with type 2 diabetes and compared GLP-1 RAs and control groups. PubMed and ClinicalTrials.gov were systematically searched from inspection till May 2024 without any language restrictions. Odds ratios (OR) and 95% confidence intervals (CI) were pooled using a random-effect model. Results: A total of 29 RCTs with 72,868 patients (35,631 in the GLP-1 RA group and 37,237 in the control group) were included in the analysis. Pooled analysis showed that there is no significant association between GLP-1 RAs and incidence of atrial fibrillation (OR, 0.94(95%CI: 0.75-1.18), P=0.60), atrial flutter (OR, 0.87(95%CI: 0.60-1.26), P=0.46), cardiac arrest (OR, 0.79(95%CI: 0.51-1.23), P=0.30), ventricular tachycardia (OR, 1.37(95%CI: 0.90-2.07), P=0.14), and ventricular fibrillation (OR, 0.91 (95%CI: 0.45-1.84), P=0.80) when compared with control group. However, GLP-RAs reduced the incidence of atrioventricular block complete (OR, 0.58 (95%CI: 0.35-0.97), P=0.04), and heart failure (OR, 0.795 (95%CI: 0.634-0.997), P=0.047). Conclusion: This study shows that GLP-1 RAs reduced the incidence of atrioventricular block complete and incidence of heart failure. However, no significant association has been observed for arrhythmias.
