Brief Summary
This study is testing two different ways of treating atrial fibrillation (AF) in people who also have heart failure with mildly reduced or preserved heart function. Patients will randomly be assigned to either rhythm control using catheter ablation or rate control using medicines. The pilot phase will determine if a larger study can be successfully carried out to see which approach better improves survival, reduces hospitalizations, and enhances quality of life.
