Effects of Combined Therapy with SGLT2i and GLP-1RAs on Atrial Fibrillation Recurrence After Catheter Ablation in Diabetic Cohorts: One-Year Outcomes from Continuous Monitoring

: To evaluate the effect of sodium-glucose cotransporter-2 inhibitors (SGLT2i), glucagon-like peptide-1 receptor agonists (GLP-1RAs), and their combination on atrial fibrillation (AF) recurrence after catheter ablation in patients with type 2 diabetes mellitus (T2DM). In a prospective cohort study, patients with T2DM undergoing AF ablation were stratified into three groups: SGLT2i-users, GLP-1RAs-users, and combined SGLT2i/GLP-1RAs users. Diabetics under SGLT2i/GLP-1RAs therapy had worse glycemic control (HbA1c > 7%). AF recurrence was assessed over 12 months using implantable continuous monitoring (ICM). Secondary outcomes included the inflammatory/oxidative stress markers measured at the 12-month follow-up. At the follow-up end, patients treated with SGLT2i/GLP-1RAs versus monotherapy patients showed significantly lower AF recurrence and serum inflammatory/oxidative stress markers, despite having higher HbA1c levels (p < 0.05). Combined SGLT2i/GLP-1RAs therapy reduced AF recurrence following catheter ablation and inflammatory/oxidative stress in T2DM patients.
