Relationship between CANLPH score and in-hospital mortality in patients undergoing coronary artery bypass grafting

Abstract

Aim: To evaluate the CANLPH score in in-hospital mortality after coronary artery bypass grafting. Materials & methods: The 999 patients were included in this retrospective cohort study. Neutrophil/lymphocyte ratio, C-reactive protein/albumin ratio and platelet/hemoglobin ratio were determined and the CANLPH score was calculated as the sum score of 0 or 1 by the cutoff in each ratio. Results: Twenty-five patients who reached the primary end point were defined as the mortality group and the remaining as the nonmortality group. The CANLPH score was noninferior to the European System for Cardiac Operative Risk Evaluation II in receiver-operating characteristic curve analysis with difference between AUC: 0.0162, standard error (SE): 0.0394, z statistics: 0.682 and p = 0.494. Conclusion: The CANLPH score may be more appropriate in assessing the risk of in-hospital mortality after coronary artery bypass grafting.
