Effect of Dapagliflozin on the Recurrence of Atrial Tachyarrhythmia in Patients Undergoing Catheter Ablation of Atrial Fibrillation
Study Details
Study Description
Brief 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 2/Phase 3 |
Detailed Description
This trial is the third phase of random allocation and non-blind trial. It is divided into study group and control group. The study group is Dapagliflozin therapy, and the treatment period is three months post catheter ablation. The control group is usual care (without Dapagliflozin). The follow-up observation period will be one year after catheter ablation. This trial was performed at Kaohsiung Chang Gung Memorial Hospital and Chang Gung Memorial Hospital, Linkou, and Chiayi branches, and it is a multi-center trial. The study flow chart is as follows.

Outcome Measures
Primary Outcome Measures
- Freedom from all atrial tachyarrhythmias (AF/AFL/AT) [3,6 and 12 months after ablation]
Freedom from all atrial tachyarrhythmias (AF/AFL/AT) greater than 30 seconds (as documented by 7-day Holter test at 3, 6, and 12-month follow-up) and 12-lead electrocardiogram (ECG) performed at cardiovascular (CV) outpatient department (OPD) follow-up within one-year post catheter ablation. (unit: %)
Secondary Outcome Measures
- Freedom from all atrial tachyarrhythmias (AF/AFL/AT) excluding the 3-month blanking period [6 and12 months after ablation]
Freedom from all atrial tachyarrhythmias (AF/AFL/AT) greater than 30 seconds (as documented by 7-day Holter at 6 and 12-month follow-up) and 12-lead ECG performed at CV OPD follow-up since 3 months post catheter ablation within one year post catheter ablation. (a conventional 3-month blanking period from catheter ablation was used in both groups during which arrhythmia recurrences were not counted toward the recurrent endpoint) (unit: %)
- Freedom from all atrial tachyarrhythmias (AF/AFL/AT) within 3-month blanking period [3 months after ablation]
Freedom from all atrial tachyarrhythmias (AF/AFL/AT) greater than 30 seconds (as documented by 7-day Holter at 3-month follow-up) or 12-leads ECG within 3 months following index ablation (within blanking period) (unit: %)
- Total mortality or hospitalization due to CV cause [12 months after ablation]
Total mortality or hospitalization due to cardiovascular cause within one year after ablation (unit: %)
- Left atrial (LA) size (LA dimension and LA volume index) by echocardiography [6 and 12 months]
Left atrial (LA) size (LA dimension in mm and LA volume index in mL/m2) by echocardiography at 6 and 12 months
- AF quality of life (QOL) by AF Effect On Quality-Of-Life (AFEQT) questionnaire score [1,3,6,9 and 12 months]
Change in AF QOL at 1 month, 3 months, 6 months, 9 months and 12 months after receiving catheter ablation relative to baseline: defined as a change in AF QOL assessed in the validated AFEQT questionnaire score. (no unit)
- N-terminal pro-brain natriuretic peptide (NT-proBNP) level [3 and 12 months]
Blood test for plasma NT-proBNP level in pg/ml
- Glycated Hemoglobin (HBA1c) [3 and 12 months]
HBA1c in %, serum creatinine in mg/dl
- Creatinine (Cr) and estimated Glomerular filtration rate (eGFR) [3 and 12 months]
serum Cr in mg/dl, estimated Glomerular filtration rate (eGFR) by MDRD formula in ml/min per 1.73 m2 (calculated according to serum Cr, age, and sex)
- Urine albumin/Cr ratio level [3 and 12 months]
Urine albumin/Cr ratio in mg/g
- Repeated catheter ablation or cardioversion for atrial tachyarrhythmia [12 months]
Repeated catheter ablation or cardioversion for atrial tachyarrhythmia within one year (unit: %)
- Adverse events: hypoglycemia, hypotension, hypokalemia, renal function deterioration [12 months]
Adverse events: hypoglycemia, hypotension, hypokalemia, renal function deterioration (defined as decline in the estimated GFR of at least 50%) (unit:%)
- AF burden [3,6 and 12 months]
AF burden in % documented by 7-day Holter at 3, 6 and 12 months
