Effect of Dapagliflozin on the Recurrence of Atrial Tachyarrhythmia in Patients Undergoing Catheter Ablation of Atrial Fibrillation

• Status: Active, not recruiting
• Trial end date: 2026-11-30
• Target enrollment: 0
• Participant gender: All

Summary

The goal of this clinical trial is to test the effect of Dapagliflozin on the Recurrence of Atrial Tachyarrhythmia in Patients Undergoing Catheter Ablation of Atrial Fibrillation. The main questions it aims to answer are:

• If Dapagliflozin will reduce the recurrence of all atrial tachyarrhythmias [atrial fibrillation (AF), atrial flutter (AFL) and atrial tachycardia (AT)] greater than 30 seconds during one-year follow-up after catheter ablation.

Participants will receive Dapagliflozin (FORXIGA) 10 milligram (mg) once a day (QD) for 3 months after catheter ablation of atrial fibrillation. Researchers will compare patients who receive usual care to see if Dapagliflozin will reduce the recurrence of all atrial tachyarrhythmias (AF/AFL/AT) during one-year follow-up after catheter ablation.

• Phase: Phase 2/Phase 3
