Description
Join host and Digital Education Committee Member, Danesh Kella, MBBS, FHRS and his guests Ratika Parkash, MD, MS, FHRS and Prashanthan Sanders, MBBS, PhD, FHRS at HRX Live 2025 in Atlanta, for this exciting discussion.
The PRAGUE-25 trial, published in JACC in 2025, compared catheter ablation with a program of lifestyle modification plus antiarrhythmic drugs in obese patients (BMI 30–40 kg/m2) with symptomatic atrial fibrillation. At 12 months, freedom from atrial fibrillation was significantly higher with ablation (73%) than with lifestyle modification + AADs (35%), despite the latter group achieving greater weight loss and metabolic improvement. The findings suggest that while aggressive risk-factor control improves overall health, catheter ablation remains more effective for rhythm control in this population.
Learning Objectives
- Describe the comparative effectiveness of catheter ablation versus lifestyle modification with antiarrhythmic drug therapy in obese patients with symptomatic atrial fibrillation.
- Discuss how weight reduction and risk-factor modification influence atrial fibrillation outcomes, while recognizing that catheter ablation provides superior rhythm control despite metabolic improvements achieved through lifestyle intervention.
