Effects of rhythm control on left atrial structure remodeling in atrial fibrillation and heart failure with preserved ejection fraction.

Background: The benefits of rhythm control for atrial fibrillation (AF) in heart failure with preserved ejection fraction (HFpEF) have not been conclusively determined. We assessed the effects of rhythm control on left atrial (LA) structure remodeling and prognosis in patients with AF and HFpEF.

Methods: This was a retrospective, real-world, observational study involving patients diagnosed with AF and HFpEF.
