Comparison of Scores for Child-Pugh Criteria and Standard and Modified Models for End-Stage Liver Disease to Assess Cardiac Hepatopathy in Heart Transplant Recipients.

Abstract

OBJECTIVES\nCongestive hepatopathy as a result of advanced heart failure correlates with poor outcomes. Thus, risk-scoring systems have been established to assess the risks for cardiac surgery and hearttransplant, although these systems were originally designed to measure mortality risk in patients with end-stage liver disease. We compared the scores for the Child-Pugh criteria andstandardandmodifiedModels for End-Stage LiverDisease to evaluate the effect of preoperative liver dysfunction on postoperative outcomes inpatients with heart failure who underwent heart transplant.\n\n\nMATERIALS AND METHODS\nData of 60 consecutive patients who underwent orthotopic heart transplant were analyzed from a historical cohort study from January 1, 2015, to December 31, 2018. We calculated the scores for Child-Pugh criteria and the standard and modified Models for End-Stage Liver Disease.\n\n\nRESULTS\nOf the 60 total patients, 48 were male patients, with a median age of 43 years (range, 13-69 years). Twenty patients died before the end of the study. The causes of death were cardiac, liver, and renal diseases. The mortality risk increased 25% (interquartile range, 0.05-0.51) for the patients with 1 point higher score compared with the patients with 1 point lower score based on a modified Model for End-Stage Liver Disease (P = .01).\n\n\nCONCLUSIONS\nPreoperative liver dysfunction has a significant effect on patient survival. The modified Modelfor End-Stage LiverDisease scoring system could be an effective predictor of perioperative risk stratification for patients with congestive hepatopathy who are undergoing cardiac transplant.
