The Effect of Glucagon-Like Peptide-1 Receptor Agonists versus Sodium-Glucose Cotransporter-2 Inhibitors Alone and in Combination on Atrial Fibrillation (AF) Recurrence and Cardiovascular Outcomes after Catheter Ablation for Atrial Fibrillation

  • Propensity score matching (PSM) analysis of the TriNetX database

Authors' conclusion

GLP-1 RA and SGLT2i alone or in combination were associated with comparable AF recurrence rates following CA for AF. However, combination therapy was consistently associated with lower all-cause mortality.

Study context

Population
Adults with AF who underwent catheter ablation (CA) for AF, TriNetX database (2018–2024)GLP-1 RA vs SGLT2i (each) 1,393 · combination vs GLP-1 RA (each) 952 · combination vs SGLT2i (each) 1,213
Exposure
GLP-1 RA vs SGLT2i, combination vs GLP-1 RA, and combination vs SGLT2i
Outcome
AF recurrence, defined as repeat CA, cardioversion, or antiarrhythmic drug use after a 3-month blanking period
