Pre-procedural TMAO as a predictor for recurrence of atrial fibrillation after catheter ablation
Abstract Background Numerous studies have demonstrated the significance of trimethylamine-N-oxide (TMAO) in the progression of atrial fibrillation (AF). However, the association between TMAO and AF recurrence (RAF) post-catheter ablation is not yet fully understood. This study aims to elucidate the...

| description | Abstract Background Numerous studies have demonstrated the significance of trimethylamine-N-oxide (TMAO) in the progression of atrial fibrillation (AF). However, the association between TMAO and AF recurrence (RAF) post-catheter ablation is not yet fully understood. This study aims to elucidate the predictive capability of pre-procedural TMAO levels in determining RAF following catheter ablation (CA). Methods This study was conducted as a prospective, single-center observational study. Between June 2021 and June 2022, 152 patients from the Department of Cardiology at The Affiliated Huaian No. 1 People’s Hospital of Nanjing Medical University were enrolled. Baseline characteristics and serum TMAO levels were assessed for all participants. Patients with AF who underwent CA were monitored for recurrences of AF using electrocardiography (ECG) or 24-hour Holter monitoring during the follow-up period. Results The study found that serum TMAO levels were significantly higher in persistent AF (PeAF) patients compared to those in sinus rhythm (SR) and paroxysmal AF (PaAF) patients (3.96 ± 1.69 vs. 1.81 ± 0.59, 3.02 ± 1.50 µM, P < 0.001 and P < 0.01, respectively). After a one-year follow-up, 29 (21.2%) AF patients experienced recurrence after CA. Multivariate Cox proportional hazards regression analysis revealed that pre-procedural serum TMAO was an independent predictor of recurrent AF (HR = 1.78, 95% CI = 1.43–2.21, P < 0.001). The receiver operating characteristic (ROC) curve analysis identified a cut-off value of 4.3µM for serum TMAO levels in predicting recurrent AF (area under the curve: 0.835, P < 0.001). The Kaplan-Meier plot demonstrated that patients with TMAO levels greater than 4.3µM had a significantly higher rate of recurrent AF (HR = 13.53, 95% CI = 6.19–29.56, P < 0.001). Conclusion Patients with AF exhibited elevated levels of circulating TMAO compared to patients with SR. The findings suggest a potential role of TMAO in the development of AF, with pre-procedural serum TMAO levels serving as a reliable predictor of recurrence of AF CA. |
