• Objective The association between natriuretic peptide levels in atrial fibrillation (AF) patients with advanced left atrial (LA) remodeling and reverse remodeling after rhythm control therapy has not been clarified. The present study assessed the role of atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) measurements to predict LA reverse remodeling after catheter ablation (CA) in persistent AF patients with LA enlargement. Methods This study included 88 persistent AF patients with LA enlargement (volume index >48 mL/m2) who underwent CA. Plasma ANP and BNP levels were analyzed before CA in all patients. The study population was divided into 2 groups according to the extent of decrease in the LA volume index (LAVI) at 6 months after CA responders were those with a ≥15% reduction in the LAVI, and all others were non-responders. Results At follow-up, 58 patients (66%) were classified as responders. The preprocedural ANP level was significantly higher in the responders than in the non-responders (p=0.03). Furthermore, the ANP-to-BNP ratio (ANP/BNP) was significantly higher in the responders than in the non-responders (p<0.01). The ANP/BNP was correlated with the percentage decrease in the LAVI (r=0.391, p<0.01). A multivariate linear regression analysis revealed that the ANP/BNP before CA was an independent predictor of LA reverse remodeling (p<0.01). Conclusion The preprocedural ANP/BNP was a robust predictor of reverse remodeling of the enlarged LA after sinus rhythm restoration by rhythm control therapy in persistent AF patients.
