SGLT2i Improve Left Atrial Function in Patients With Paroxysmal Atrial Fibrillation, Hypertension and Abnormal Glucose Metabolism
China66 participantsStarted 2025-03-01
Plain-language summary
Heart failure is the most important clinical endpoint event in atrial fibrillation (AF). Patients with AF complicated by heart failure have a significantly higher risk of all-cause mortality and cardiovascular mortality compared to those without heart failure. Abnormal left atrial function is an important mechanism leading to the occurrence of AF-related heart failure. Therefore, it is essential to find drugs that can improve left atrial function to prevent heart failure in patients with AF. Sodium-glucose cotransporter 2 inhibitors (SGLT2i) are important drugs for regulating metabolic abnormalities. Studies have found that these drugs also reduce the risk of new-onset AF in patients with heart failure. Thus, the investigators hypothesize that SGLT2i may be able to regulate left atrial function.
This study is a multicenter randomized controlled trial using three-dimensional speckle tracking echocardiography to investigate whether SGLT2i can improve left atrial function and prevent heart failure in patients with paroxysmal AF who have hypertension and metabolic disorders, compared to placebo. The investigators also observed the effects of SGLT2i on cardiovascular and metabolic risk factors. The investigator team has a solid foundation in the field of cardiovascular metabolism, having completed the evaluation of left atrial function in paroxysmal AF using three-dimensional speckle tracking technology over the past three years. This study is the first to propose that SGLT2i can improve left atrial function in paroxysmal AF patients with metabolic abnormalities, which is of great significance for preventing heart failure in this type of AF.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
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.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
