Sinus Rhythm Wins
Ablation Plus Lifestyle Change Is the New Gold Standard for AF.

Key Notes:
1. PRAGUE-25 Trial – Main Finding
• Compared catheter ablation (CA) vs. lifestyle modification + antiarrhythmic drugs in AF patients.
• At 12 months: 73% in CA group free of AF vs. 34.6% in the lifestyle+drug group.
• At 24 months: 55.6% (CA) vs. 24.7% (non-invasive group).
• Conclusion: CA is more effective at maintaining sinus rhythm (SR).
2. Experts Recommend a Combined Strategy
• Best outcomes come from ablation + risk factor control.
• Lifestyle change improves ablation durability.
3. Why Sinus Rhythm (SR) Matters
• SR linked to lower risk of:
• Stroke, death, bleeding, and cardiac arrest (CABANA trial).
• All-cause death reduced by 41% in patients maintaining SR.
4. Guidelines Have Shifted
• Recent updates (2023 AHA/ACC/HRS): Early rhythm control is now preferred.
• Rhythm control is especially important in younger patients and those with heart failure.
5. Treatment Should Be Personalized
• Not every patient needs ablation, but all should be informed.
• Antiarrhythmic drugs may help post-ablation, but relapse is common long-term.
• Lifestyle change is difficult but essential. GLP-1 agonists may support weight loss in AF patients.
Anticoagulation after AF Ablation
Even after successful ablation, most patients still need anticoagulants if their CHA₂DS₂-VASc score is high, because AF can silently return and stroke risk remains.
