Tóm tắt

 BACKGROUND: Contrast-induced acute kidney injury (CI-AKI) is a common complication of percutaneous coronary intervention (PCI) in ST-elevation myocardial infarction (STEMI) patients. Our aim was to assess the lymphocyte to C-reactive protein ratio (LCR) to predict CI-AKI in patients with acute STEMI. METHODS: A total of 777 patients with STEMI undergoing primary PCI were continuously included in this study. The occurrence of CI-AKI was monitored during the follow-up period for all patients. Logistic regression analysis was employed to assess the relationship between LCR and CI-AKI. Furthermore, ROC analysis was conducted to establish the optimal LCR cut-off value for the prediction of CI-AKI. RESULTS: The incidence of CI-AKI after PCI was 12.2% (95/777). Univariate and multivariate analysis showed that LCR was an independent factor for CI-AKI after PCI. ROC curve analysis of LCR showed the optimal cut-off value of LCR identified for predicting CI-AKI was 7875.94, yielding the area under the curve of 0.626 (95% CI: 0.572-0.679
  P <
  0.002). The integration of the LCR could significantly improve the ability of the model to identify CI-AKI (IDI = 0.016[P <
  0.002], and NRI = 0.137[P = 0.006]). CONCLUSION: LCR is an independent risk factor for CI-AKI in STEMI patients undergoing primary PCI. Integration of LCR can significantly improve the risk model for CI-AKI.
