title: The Impact of Chronic Liver Diseases on the Level of Heart-Type Fatty Acid-Binding Protein (H-FABP) Concentrations.
abstract: OBJECTIVE
  Heart-type fatty acid binding-protein (H-FABP) has been reported to be a potential novel biochemical marker for the early diagnosis of acute myocardial infarction (AMI). The presence of H-FABP in the liver has not been reported. The aim of this study was to compare the effect of chronic liver diseases on the level of H-FABP concentrations.
  
  
  METHODS
  The effects of chronic liver diseases including infective hepatitis and cirrhosis on the concentration of H-FABP was studied in a small group of patients (n=10, mean age ±SD = 58.33 ± 7.19 years). The serum concentrations of the following markers were measured: H-FABP, alanine aminotransferase (ALT) and bilirubin and compared with a reference control group (20 healthy blood donors, mean age ±SD = 63.8 ±8.01).
  
  
  RESULTS
  The serum concentrations of these markers in the control group as compared to patients with chronic liver disease were as follows (mean ± SD): H-FABP = 6.86 ±2.21 μg/L versus 6.44 ±3.06 μg/L (p = NS); ALT = 29.8 ±14.7 U/L versus ALT = 198.67 ±122.89 U/L (p < 0.0005) and bilirubin = 9.6 ±4.0 μmol/L versus bilirubin = 100.89 ±87.85 μmol/L (p < 0.0001).
  
  
  CONCLUSIONS
  These data illustrate clearly that there is no significant interference with the normal concentration of H-FABP in the presence of liver diseases, despite the significant elevation of liver enzymes and proteins. These data may support a useful role of H-FABP for the diagnosis of myocardial injury in patients with liver diseases.
