Multicenter clinical study of the predictive value of neutrophil gelatinase-associated lipocalin for contrast-induced acute kidney injury after emergency percutaneous coronary intervention in patients with relative normal renal function / 实用医学杂志

Objective To explore the predictive value of neutrophil gelatinase associated lipocalin (NGAL) for contrast-induced acute kidney injury (CI-AKI) after emergency percutaneous coronary interventions (PCI) in patients with relative normal renal function.Methods A total of 73 patients with relative normal renal function undergoing PCI were enrolled in this prospective multicenter clinical study.Serum NGAL was measured by point-of-care test.Receiver operating characteristic (ROC) curve was used to analyze the diagnostic value of NGAL for CI-AKI.Results CI-AKI occurred in 5 patients (6.85％).The concentration of NGAL was higher in the CI-AKI group than in the non-CI-AKI group.ROC curve indicated that the area under the receiver operating characteristic was 0.755,0.761 and 0.809,respectively.Conclusions Serum NGAL at baseline,4 h and 8 h after procedure are served as a good biomarker for early diagnosis of CI-AKI after PCI.Therefore,NGAL might become an early and quick marker for CI-AKI in the future.
