Study Details

Brief summary:

This prospective randomized pilot study aims to evaluate the impact of aggressive life style modification in terms of calorie-controlled diet and supervised exercise on outcome of catheter ablation in overweight and obese patients with atrial fibrillation.

Hypothesis: Weight loss and management by adoption of strict diet and exercise regimen improves the chances of freedom from recurrence following catheter ablation.
