Summary

This study tests whether a structured cardiac rehabilitation program with exercise and lifestyle coaching, started after a standard catheter ablation procedure, can help obese patients with atrial fibrillation stay free from the heart rhythm disorder longer. Researchers will follow 520 participants for at least a year, comparing those who get the rehab program to those who receive usual care. The goal is to see if lifestyle changes can improve long-term outcomes beyond the procedure alone.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Cardiac rehabilitation and lifestyle modification program
What this could lead to
If successful, this could show that adding exercise and lifestyle changes after a standard heart procedure helps obese patients stay free from atrial fibrillation longer.
What could go wrong
This is an early-stage behavioral study, not a drug trial. Results may vary widely, and the benefit may be modest or hard to separate from usual care.
