Abstract：Objective To discuss the correlation among left atrial volume(LAV),systolic pulmonary arterial pressure(sPAP)and atrial fibrillation(AF)after aortic valve replacement(AVR).Methods The patients underwent aortic valve replacement(n=144)were selected from the First Affiliated Hospital of Chinese PLA Air Force Medical University from May 2021 to July 2023.All patients were divided,according to AF occurrence after the operation,into AF group(n=57)and non-AF group(n=87).Clinical data and indicators of preoperative cardiac ultrasound and laboratory were recorded in 2 groups.The risk factors related to AF occurrence after aortic valve replacement were analyzed by using Logistic regression model.The predictive value of predictors for AF occurrence after aortic valve replacement was assessed by using ROC curve.Results The results of univariate analysis showed that age,tumor necrosis factor-α(TNF-α),left ventricular ejection fraction(LVEF),LAV,left atrial end-diastolic inner diameter(LAEDd),and sPAP were associated with AF occurrence in patients after AVR(P<0.05).The results of multivariate analysis showed that age(OR=1.230,P=0.001),LAV(OR=1.049,P=0.014),and sPAP(OR=0.121,P=0.000)were independent risk factors for postoperative AF occurrence in patients.The results of ROC curve analysis showed that age,LAV,sPAP,and the combined prediction of these three factors were all statistically significant for predicting AF occurrence(P=0.000,P=0.003,P=0.000,P=0.000).The results of Pearson analysis showed that age(r=0.338,P=0.000),LAV(r=0.261,P=0.002)and sPAP(r=0.427,P=0.000)had significant positive correlation with postoperative AF occurrence.Conclusion Age,LAV and sPAP are independent risk factors for postoperative AF occurrence,and they have some diagnostic value to predict AF occurrence and combined prediction of these three factors has a higher predictive value.
