Impact of Pre-Ablation Prehabilitation on Clinical Outcomes and Cardiorespiratory Fitness in Atrial Fibrillation Patients

This study is testing whether a supervised exercise program done before a heart ablation procedure (a treatment for irregular heartbeat called atrial fibrillation) can improve fitness and recovery outcomes. Called prehabilitation, this approach aims to get patients in better shape before their procedure. **You may be eligible if...** - You are between 18 and 70 years old - You are scheduled for your first ablation procedure for atrial fibrillation - You have mild to moderate heart failure symptoms (NYHA class I or II) - Your heart's pumping function is 50% or better (preserved ejection fraction) **You may NOT be eligible if...** - You have severe valve disease or other major structural heart problems - You have a condition that prevents safe exercise testing - You have significant cognitive impairment - You have had a prior ablation for atrial fibrillation Talk to your doctor to see if this trial is right for you.
