RESUMO
Objective:To analyze the risk factors of postoperative recurrence of nonvalvular paroxysmal and persistent atrial fibrillation.Methods:A total of 100 patients who received treatment in Haining People's Hospital from October 2019 to October 2021 were included in this study. All patients were followed up for 1 year. Thirty patients with postoperative recurrence of atrial fibrillation were included in the observation group, and seventy patients without postoperative recurrence of atrial fibrillation were included in the control group. Univariate and multivariate logistic regression analyses were performed to analyze the risk factors of postoperative recurrence of atrial fibrillation after radiofrequency ablation.Results:Logistic regression analysis results revealed that age, body mass index, diabetes mellitus, hypertension, rheumatic heart disease, anteroposterior diameter of the left atrium, glycosylated hemoglobin, brain natriuretic peptide are the risk factors of recurrent atrial fibrillation after radiofrequency ablation (all P < 0.05) ( OR = 1.31, 1.33, 1.32, 1.34, 1.26, 1.24, 1.36, 1.33; 95% CI = 1.028-1.442, 1.031-1.427, 1.042-1.434, 1.124-1.452, 1.013-1.385, 1.005-1.326, 1.039-1.482, 1.064-1.478). Conclusion:The recurrence of nonvalvular paroxysmal and persistent atrial fibrillation after radiofrequency ablation is related to many factors. The risk factors should be taken into account in clinical practice, and targeted treatment should be given as early as possible to reduce the recurrence rate of atrial fibrillation and improve prognosis.
