Association Between Different Versions of the Model for End-Stage Liver Disease Score and Contrast-Associated Acute Kidney Injury in Patients Undergoing Elective Percutaneous Coronary Intervention

Background:Pre-procedure liver dysfunction was associated with acute kidney injury after percutaneous coronary intervention (PCI). The aim of this study is to assess and compare the predictive value of different liver function scoring systems for contrast-associated acute kidney injury (CA-AKI) in p...

Description
Summary:Background:Pre-procedure liver dysfunction was associated with acute kidney injury after percutaneous coronary intervention (PCI). The aim of this study is to assess and compare the predictive value of different liver function scoring systems for contrast-associated acute kidney injury (CA-AKI) in patients undergoing elective PCI.Methods and Results:A total of 5,569 patients were retrospectively enrolled. The model for end-stage liver disease (MELD) including albumin (MELD-Albumin) score (AUC=0.661) had the strongest predictive value in comparison to the MELD score (AUC=0.627), the MELD excluding the international normalized ratio (MELD-XI) score (AUC=0.560), and the MELD including sodium (MELD-Na) score (AUC=0.652). In the fully adjusted logistic regression model, the MELD-Albumin score and the MELD-Na score were independently associated with CA-AKI regardless of whether they were treated as continuous or categorical variables; however, this was not the case for the MELD score and the MELD-XI score. Furthermore, the addition of the MELD-Albumin score significantly improved the reclassification beyond the fully adjusted logistic regression model. The study further explored the association between different versions of the MELD score and CA-AKI using restricted cubic splines and found a linear relationship between the MELD-Albumin score and the risk of CA-AKI.Conclusions:The MELD-Albumin score had the highest predictive value for CA-AKI in patients undergoing elective PCI. The addition of the MELD-Albumin score to the existing risk prediction model significantly improved the reclassification for CA-AKI.
