- W3029124727 abstract "ObjectiveTo investigate the effects and related risk factors of different vascular access types on new atrial fibrillation in maintenance hemodialysis (MHD) patients.MethodsThis was a single-center prospective cohort study. Patients who established long-term dialysis access and were voluntarily followed up in the Second Hospital of Tianjin Medical University from January 1, 2013 to June 30, 2013 were enrolled to follow-up for 5 years. Patients were divided into fistula group (patients with autogenous arteriovenous fistula) and catheter group (patients with tunneled cuffed internal jugular vein catheter). The incidences of new atrial fibrillation in the two groups were compared by Kaplan-Meier survival analysis. Cox regression analysis and receiver operator characteristic curve (ROC) were used to assess the risk factors of new atrial fibrillation.ResultsA total of 315 eligible patients were enrolled, including 150 males (47.62%). There were 189 patients (60.00%) in the fistula group, and 126 patients (40.00%) in the catheter group. Multivariate Cox regression analysis showed that older age (HR=1.021, 95%CI 1.003-1.040), arteriovenous fistula (HR=1.899, 95% CI 1.019-3.539), increased dialysis blood flow (HR=1.030, 95% CI 1.010-1.051) and left atrial diameter (HR=1.097, 95%CI 1.022-1.177) were independent risk factors for new atrial fibrillation in MHD patients (all P<0.05). Kaplan-Meier survival analysis showed that the incidence of new atrial fibrillation in fistula group was higher than that in catheter group (Log-rank χ2=9.53, P=0.002). ROC curve analysis showed that age [the area under the curve (AUC)=0.608, P=0.008], arteriovenous fistula (AUC=0.594, P=0.021), dialysis blood flow (AUC=0.659, P<0.001) and left atrial diameter (AUC=0.604, P=0.011) could predict the occurrence of new atrial fibrillation.ConclusionsOlder age, arteriovenous fistula, increased blood flow during dialysis and left atrial diameter are independent risk factors for new atrial fibrillation in MHD patients, which can predict the occurrence of atrial fibrillation. The incidence of new atrial fibrillation in patients with arteriovenous fistula is higher than that in patients with catheter.Key words: Renal dialysis; Atrial fibrillation; Cohort studies; Catheters, indwelling; Vascular access" @default.
