Could a common diabetes drug repair heart damage in atrial fibrillation?
NCT ID NCT05993897
First seen Jul 13, 2026 · Last updated Jul 14, 2026 · Updated 1 time
Summary
This study investigates whether dapagliflozin, a drug typically used for diabetes, can improve the structure and function of the heart's left atrium in people with paroxysmal atrial fibrillation (a type of irregular heartbeat that comes and goes). Researchers will measure changes in heart size and strain using imaging, regardless of whether participants have diabetes. The trial involves 60 adults aged 18–60 with normal to mildly enlarged left atria and adequate kidney function.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Dapagliflozin (SGLT2 inhibitor)
- What this could lead to
- If successful, this could show that SGLT2 inhibitors help reverse heart damage in atrial fibrillation, potentially reducing complications like stroke and heart failure.
- What could go wrong
- This is a small, early-phase study with 60 participants, so results may not apply broadly. The drug may not improve heart remodeling or could cause side effects like dehydration or kidney issues.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. with non-valvular paroxysmal atrial fibrillation (AF that terminates spontaneously or with intervention within seven days of onset). 2. Patient age 18-60 years. 3. Patients with Glomerular Filtration Rate (GFR) \>45 ml/min/1.73m2 (Cockcroft-Gault equation). 4. Patient with normal left atrium or dilated (diameter \<5 cm) Exclusion Criteria: 1. Patients \< 18 yrs old. 2. Patients with valvular heart diseases (Moderate to severe MS, severe AS, Prosthetic heart valves). 3. Patients with left atrium \> 5cm. 4. Patients with glomerular Filtration Rate (GFR) \<45 ml/min/1.73m2 (Cockcroft-Gault equation). 5. Patient with ischemic heart disease (previous MI, UA, PCI or CABG). 6. Patient with previous ischemic stroke.
