NT‐proBNP as a Predictor of Atrial Fibrillation Recurrence After Cryoballoon, Radiofrequency and Pulsed‐Field Ablation

Key Result

NT-proBNP serves as a predictor of atrial fibrillation recurrence following cryoballoon, radiofrequency, and pulsed-field ablation.

Key Points

• This research aims to evaluate the role of NT-proBNP in predicting the recurrence of atrial fibrillation following various ablation techniques.
• Analyzed data from the Swiss-AF-PVI registry
• Included patients who underwent cryoballoon, radiofrequency, or pulsed-field ablation
• Measured NT-proBNP levels before and after ablation procedures
• Higher NT-proBNP levels were associated with increased risk of atrial fibrillation recurrence
• Different ablation techniques showed varying implications of NT-proBNP as a predictive biomarker
