Objective To explore the prevalence and related factors of atrial fibrillation（AF）in maintenance hemodialysis （MHD）patients. Methods Patients undergoing MHD at Beijing ChaoYang Hospital Affiliated to Capital Medical University from March to August 2022 were enrolled, and were divided into AF group and non-atrial fibrillation（non-AF）group based on whether they had atrial fibrillation. Multivariate logistic regression model and receiver operator characteristic（ROC）curves were used to evaluate the related factors of AF and its predictive value. Results A total of 117 patients were enrolled. Patients in AF group had significantly higher age,hemodialysis vintage,ultrafiltration rate,red blood cell distribution width, high-sensitivity C-reactive protein（hs-CRP）,brain natriuretic peptide,and left atrial diameter than those in non-AF group,while serum albumin and left ventricular ejection fraction were significantly lower in AF group（P< 0.05）. Multivariate logistic analysis showed that left atrial diameter,ultrafiltration rate, hemodialysis vintage,hs-CRP and advanced age were related factors for AF（P< 0.05）. The area under the ROC curve of ultrafiltration rate was 0.695, and the optimal cut-off value was 11.6 ml/（kg·h）. Conclusions The proportion of asymptomatic atrial fibrillation in MHD patients is high,and it often occurs during the dialysis process. Left atrial diameter, ultrafiltration rate, hemodialysis vintage, hs-CRP and age are related factors of AF.
