Abstract:
Objective: To investigate the predictive value of neutrophils-to-lymphocytes ratio (NLR) for atrial fibrillation recurrence after radiofrequency ablation in atrial fibrillation patients combined with heart failure. Methods: This is a retrospective cohort study. Patients with atrial fibrillation and heart failure who received radiofrequency ablation in the First Affiliated Hospital of Zhengzhou University from January 2019 to June 2020 were included. Patient were followed up in the outpatient clinic at 3, 6, 9 and 12 months after radiofrequency ablation and were divided into recurrent and non-recurrent groups according to the absence or presence of atrial fibrillation. Demographic data, echocardiographic indices and inflammation-related indices including NLR were collected and compared between the two groups. Spearman rank correlation was performed to analyze the correlation of NLR with atrial fibrillation recurrence after radiofrequency ablation. Multivariate logistic regression analysis was used to determine independent risk factors of atrial fibrillation recurrence after radiofrequency ablation. The receiver operating characteristic (ROC) curve was used to evaluate the value of NLR in predicting the atrial fibrillation recurrence after radiofrequency ablation. Results: A total of 883 patients were included, of which 460 (52.1%) were male, mean age was (64.4±10.7) years old. There were 246 patients (27.9%) in the recurrence group and 637 patients (72.1%) in the non-recurrence group. Compared with the non-recurrent group, the duration of atrial fibrillation, NLR, neutrophil count, N-terminal B-type natriuretic peptide precursor (NT-proBNP) and body mass index levels were significantly higher, while lymphocyte count was significantly lower in the recurrence group than in the non-recurrent group (all P<0.05). Spearman rank correlation analysis showed that NLR was positively correlated with the atrial fibrillation recurrence (r=0.333, P<0.05). Multivariate logistic regression analysis showed that NLR was an independent risk factor for atrial fibrillation recurrence after radiofrequency ablation in atrial fibrillation patients combined heart failure (OR=1.634, P<0.001). The ROC curve showed that the area under the curve (AUC) of NLR in predicting the recurrence of atrial fibrillation after radiofrequency ablation was 0.715 (95%CI: 0.668-0.762, P<0.001), with a sensitivity of 55.61% and a specificity of 84.54%. Conclusion: NLR is a useful predictor of atrial fibrillation recurrence after radiofrequency ablation in atrial fibrillation patients combined with heart failure.
