Differential Impact of Body Mass Index on Recurrence, Cardiac Remodelling, and Quality of Life After Atrial Fibrillation Ablation: Insights From the China‐ AF Registry

Key Result

Higher BMI is linearly associated with atrial fibrillation recurrence, while obesity is linked to nonlinear adverse cardiac remodeling after radiofrequency catheter ablation.

Key Points

To examine how body mass index influences atrial fibrillation recurrence, cardiac remodelling, and quality of life after ablation.
Analyzed data from the China-AF registry
Assessed the relationship between BMI and AF recurrence
Evaluated cardiac remodelling metrics like LVEDD and LVWT
Higher BMI is associated with increased atrial fibrillation recurrence after radiofrequency catheter ablation
Obesity shows a nonlinear impact on cardiac remodelling indicators
Findings suggest that weight management is crucial for improving post-ablation outcomes

Structured PICO

Does higher BMI impact recurrence, cardiac remodelling, and quality of life after atrial fibrillation ablation?

Population

Patients undergoing atrial fibrillation ablation (RFCA) in the China-AF Registry

Intervention

Higher Body Mass Index (BMI) / Obesity

Comparator

Lower BMI / Non-obese patients

Outcome

Atrial fibrillation recurrence, cardiac remodelling (LVEDD and LVWT), and quality of life

Higher BMI is linearly associated with increased AF recurrence and nonlinearly linked to adverse cardiac remodeling following AF ablation.

Main Result

Absolute Event Rate: 0% vs 0%

Abstract

Higher BMI exhibits a linear association with AF recurrence post-RFCA. Obesity is linked to nonlinear adverse remodelling (LVEDD and LVWT).
