Abstract:
Objective:To investigate the risk factors of atrial fibrillation (AF) in patients with typical atrial flutter after radiofrequency ablation.Methods:This study was a case-control study. The clinical data of 120 patients with typical atrial flutter who underwent radiofrequency ablation in Xingtai People′s Hospital from January 2017 to January 2021 were retrospectively analyzed. Patients were followed up every 3-6 months for a period of 2 years, and AF occurred in 30 patients (25.0%). The risk factors of AF were analyzed with univariate and multivariate logistic regressions.Results:The mean age of patients was (62.0±6.5) years and 64(53.3%) were males. No patients in the two groups had complications such as cardiac tamponade, pulmonary embolism and cerebral infarction after radiofrequency ablation. Compared with non-AF patients, patients in AF group had older age and higher CHA 2DS 2-VASC score ( P<0.001). Multivariate regression analysis showed that age ( HR=1.09, 95% CI:1.01-1.17) and CHA 2DS 2-VASC score ( HR=3.84, 95% CI:1.87-7.89) were independent risk factors for the occurrence of atrial fibrillation after radiofrequency ablation in patients with atrial flutter. Conclusion:After radiofrequency ablation of typical atrial flutter, nearly 25% of patients will relapse into AF, old age and higher CHA 2DS 2-VASC score increase the risk of AF recurrent.
