BACKGROUND: The aim of this study was to analyze the relationship between abnormal liver function tests (LFTs) coincident with heart failure (HF) exacerbation and subsequent long-term outcome in patients with chronic HF. METHODS AND RESULTS: The study population consisted of 183 consecutive patients admitted for HF exacerbation with left ventricular ejection fraction < or =40%. Cox proportional hazard analysis revealed that serum total bilirubin (T-Bil) levels on admission (hazard ratio 1.896, p<0.001, 95% confidence interval 1.323-2.717), but not T-Bil at discharge or other LFTs, was an independent predictor of subsequent cardiac events after hospital discharge (cardiac death or readmission for HF exacerbation) The cardiac-event-free rates significantly decreased according to increasing tertiles of T-Bil stratified by the level of 0.7 and 1.2 mg/dl (p<0.001). T-Bil on admission had significant correlations with simultaneously-measured central venous pressure (CVP) (r=0.42, p<0.01) and cardiac index (CI) (r= -0.50, p<0.01). The patients demonstrating high CVP together with low CI showed significantly increased T-Bil compared with any other group. CONCLUSIONS: Increased T-Bil coincident with cardiac decompensation predicts a worse long-term prognosis of CHF, presumably through the potential liability to both congestion and tissue hypoperfusion simultaneously when HF deteriorates.
