Predictive Value of Hepatic and Renal Dysfunction Based on the Models for End-Stage Liver Disease in Patients With Heart Failure Evaluated for Heart Transplant.

BACKGROUND: The evaluation of prognosis and determination of a long-term treatment strategy is an important element of management in patients with heart failure (HF).

METHODS: The aim of the study was to determine the prognostic value of the Model for End-Stage Liver Disease (MELD) and its modifications, MELD and serum sodium (MELD-Na) and MELD excluding the international normalized ratio (MELD-XI), as well as other independent risk factors for death during a 4-year follow-up. We analyzed retrospectively 143 patients with advanced HF, evaluated for heart transplant between 2009 and 2011. Patients using warfarin were excluded from the study. The long-term follow-up data were obtained during follow-up visits and/or phone contact with the patients or their families.

RESULTS: The age of the patients was 54 (48-59) years and 88.1% of patients were male. Mortality rate during the follow-up period was 49%. The MELD scores (hazard ratio [HR], 1.12; P < .001), as well as serum high-sensitivity C-reactive protein (hs-CRP; HR, 1.01; P < .01) and N-terminal pro-brain natriuretic peptide (NT-proBNP; HR, 1.01; P < .05) levels, were independent risk factors for death. Receiver operator characteristic analysis indicated that a MELD cutoff of 10 (area under the curve [AUC], 0.756; P < .0001], MELD-XI cutoff of 13.0 (AUC, 0.720; P < .0001), MELD-Na cutoff of 13.0 (AUC, 0.813; P < .0001), hs-CRP cutoff of 4.02 (AUC, 0.686; P < .001), and NT-proBNP cutoff of 1055 (AUC, 0.722; P < .001) were the best predictive values as predictors of death.

CONCLUSIONS: MELD, MELD-Na, and MELD-XI scores are prognostic factors for death during a 4-year follow-up. A high MELD score is an independent prognostic factor for death. NT-proBNP and hs-CRP serum concentrations are other independent factors influencing death.
