Objective To investigate the relationship between the incidence of contrast-induced acute kidney injury (CI-AKI) and the level of fibrinogen (FIB) and CHA2DS2-VASc scores in patients with acute coronary syndromes (ACS) undergoing percutaneous coronary intervention (PCI), and to further compare the predictive value of FIB, CHA2DS2-VASc scores and their combination for CI-AKI. Methods The clinical and laboratory data of 934 ACS patients who underwent PCI in our hospital from December 2018 to January 2021 were retrospectively analyzed, and CHA2DS2-VASc scores were calculated. According to postoperative creatinine changes, all patients were divided into CI-AKI and non-CI-AKI groups, and baseline information was compared between the two groups. The correlation between FIB and CHA2DS2-VASc scores was assessed by Spearman correlation analysis. ROC curves were plotted to evaluate the predictive value of FIB, CHA2DS2-VASc scores, and their combined levels on CI-AKI, and logistic regression analysis was used to study the risk factors of CI-AKI in patients with ACS after PCI. Results Patients with high FIB and high CHA2DS2-VASc scores had a higher incidence of CI-AKI after PCI. Correlation analysis showed that FIB and CHA2DS2-VASc scores were positively correlated (R=0.236, P<0.001). The combined prediction of the area under the ROC curve of CI-AKI after PCI in ACS patients was 0.727 (95%CI: 0.697~0.755, P<0.001), the sensitivity was 63.3%, and the specificity was 72.6%. The cut-off values of FIB and CHA2DS2-VASc scores to predict the occurrence of CI-AKI in ACS patients divided 934 ACS patients into low-risk (404 cases), mediumrisk (383 cases), and high-risk groups (147 cases). Multivariate logistic regression analysis showed that albumin level (OR=0.913, 95%CI: 0.867~0.962, P=0.001), FIB level (OR=1.451, 95%CI: 1.185~1.777, P<0.001), CHA2DS2-VASc score (OR=1.271,95%CI: 1.504~1.780, P<0.001) were independent influences on CI-AKI after PCI in patients with ACS, P<0.05). Conclusion The preoperative fibrinogen level and CHA2DS2-VASc score have certain predictive value for the occurrence of CI-AKI after interventional diagnosis and treatment. The combination of the two can improve the accuracy of the prediction of CI-AKI after PCI in ACS patients.
