Could a common diabetes drug shield hearts from AF-Related failure?
NCT ID NCT07482020
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether empagliflozin, a diabetes drug, can improve left atrial function in 66 people with paroxysmal atrial fibrillation, high blood pressure, and abnormal glucose metabolism. The goal is to see if it can prevent heart failure. Participants will be randomly assigned to receive the drug or a placebo, and heart function will be measured using advanced imaging.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- empagliflozin (an SGLT2 inhibitor)
- What this could lead to
- If it works, this could point toward a new way to prevent heart failure in people with atrial fibrillation and related metabolic problems.
- What could go wrong
- This is a small, early-phase trial (66 people) testing a surrogate marker, not hard outcomes. The drug may not improve heart function or prevent heart failure in real-world settings.

Inclusion Criteria: * • Patients aged 18-80 years, treated in the outpatient or inpatient departments of each research center and included in the AF database. * Patients with paroxysmal AF confirmed by 12-lead electrocardiogram, 24-hour Holter monitoring, or handheld electrocardiogram devices. * Patients with hypertension who have already started antihypertensive treatment. * Patients with diabetes who have already started antidiabetic treatment, or patients with prediabetes who have not received antidiabetic treatment but have an HbA1c level within the range of 6.1-6.4% in the past three months. Exclusion Criteria: * • Atrial fibrillation caused by severe mitral stenosis. * Atrial fibrillation with severe mitral regurgitation and severe tricuspid regurgitation. * Patients who have been clinically diagnosed with heart failure (heart failure with preserved ejection fraction or heart failure with reduced ejection fraction). * Special types of cardiomyopathy: amyloid cardiomyopathy, Fabry disease, muscular dystrophy, hypertrophic obstructive cardiomyopathy, etc. * Patients with a history of myocardial infarction within the past three months. * Pregnant women.
