The objective of this study was to explore potential predictors inherent to AKI.<\/jats:p><jats:p><jats:bold>Methods:<\/jats:bold> VSD infants who were scheduled for elective cardiac surgery with CPB from 2017 to 2020 were enrolled in this study. Based on the Pediatric Risk, Injury, Failure, Loss, End-Stage Renal Disease (pRIFLE) criteria, patients were divided into AKI and non-AKI groups. Univariate and multivariate logistic regression analyses were carried out in order to evaluate potential risk factors for AKI. Receiver operating characteristic (ROC) curves were generated to evaluate the predictive probabilities of risk factors for AKI.<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold> Of all the 338 enrolled VSD infants, 49 manifested AKI with an incidence of 14.5% (49\/338). The ROC curve indicated that albumin-to-fibrinogen ratio (AFR) during CPB was a significant predictor of AKI [area under the curve (AUC), 0.711; <jats:italic>p<\/jats:italic> &amp;lt; 0.001]. Based on the univariate and multivariate logistic analyses, AFR during CPB [odds ratio (OR), 1.89; 95% confidence interval (CI), 1.22\u20132.76, <jats:italic>p<\/jats:italic> = 0.011] was the only independent risk factor for AKI.<\/jats:p><jats:p><jats:bold>Conclusions:<\/jats:bold> This study demonstrated that a low AFR (&amp;lt;9.35) during CPB was an independent risk factor for AKI in VSD
