Could a common diabetes drug keep your heart in rhythm?
NCT ID NCT07187570
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tests whether dapagliflozin, a drug typically used for diabetes, can prevent atrial fibrillation from coming back after a procedure called cardioversion (an electric shock to restore normal heart rhythm). About 1600 adults with AF will take either dapagliflozin or no extra drug for up to 56 days. Researchers will track heart rhythm using a handheld device to see if the drug reduces recurrence.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- dapagliflozin (a diabetes drug that lowers blood sugar and may help heart rhythm)
- What this could lead to
- If it works, this could offer a new, short-term treatment to prevent atrial fibrillation from coming back after cardioversion.
- What could go wrong
- This is a phase 3 trial, but it's still early to know if dapagliflozin truly helps AF. The drug may not reduce recurrence, and side effects like dehydration or kidney issues are possible.

Inclusion Criteria: * Patients with AF on ECG who are planned for electrical cardioversion within 7-26 days from inclusion-date. * Age ≥ 55 years. * Provided written informed consent. Exclusion Criteria: * Current treatment with an SGLT2 inhibitor. * Prior/current diagnosis of heart failure. * Type 1 diabetes mellitus. * Estimated glomerular filtration rate (eGFR) \< 25 mL/min/1.73m2. * Pulmonary vein isolation within preceding 3 months or planned pulmonary vein isolation during the study period (56 days). * Contraindications to SGLT2 inhibitors. * Any condition or circumstance in which the patient should not participate in the study according to the study investigator.
