FABP3 and myocardial infarction: H-FABP, a low-molecular-weight protein (132 amino acids), is integral to myocardial fatty acid metabolism [10,14].  Abundantly present in cardiomyocytes, H-FABP is rapidly released into the cytosol during acute myocardial infarction (AMI) [10]. H-FABP could be a useful indicator for the early identification of high-risk patients in the general population.
