Atrial fibrillation (AF) is a major public health burden worldwide. Heart failure (HF) is one of the most common causes of death in patients with AF. Clinical trials have indicated that SGLT2i can reduce the risk of AF and HF in patients with diabetes, and improve the prognosis in patients with HF. However, whether SGLT2i can improve cardiac function and reduce the risk of HF in patients with AF remains unclear. The purpose of the HENA-AF trial is to evaluate the effects of henagliflozin on cardiac structure, function, and biomarkers of HF in patients with AF.~The HENA-AF trial will include approximately 100 persistent AF patients with enlarged left atrium and at least another cardiovascular risk factor. Participants will be randomized to henagliflozin or placebo. Cardiac MRI will be performed at baseline and at 6 months to measure the changes in cardiac structure and function. The primary hypothesis is that henagliflozin will reduce the left atrial volume index at 6 months in patients with AF.
