What this trial studies

This study investigates the impact of Dapagliflozin on the burden of atrial fibrillation (AF) in patients with diabetes mellitus (DM). Participants diagnosed with paroxysmal AF and DM will be randomized to receive either Dapagliflozin or a placebo. The primary outcome will be measured through continuous heart rhythm monitoring over a two-week period, along with assessments of quality of life and echocardiographic indices. The goal is to explore the therapeutic potential of SGLT2 inhibitors in reducing AF burden and improving patient outcomes.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals diagnosed with diabetes mellitus and paroxysmal atrial fibrillation.

Not a fit: Patients with type 1 diabetes, severe renal impairment, or those currently taking anti-arrhythmic drugs may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new treatment option for patients with diabetes and atrial fibrillation, potentially reducing AF burden and improving quality of life.

How similar studies have performed: While SGLT2 inhibitors have shown cardiovascular benefits in other studies, this specific approach to atrial fibrillation is novel and has not been extensively tested.
