The utility of H-FABP levels to predict critical cardiac events for patients with idiopathic dilated cardiomyopathy was evaluated by Komamura et al. They measured the serum concentrations of H-FABP, brain natriuretic peptide and cardiac troponin T in 92 patients with NIDCM. This evidence concerns the gene NPPB and idiopathic dilated cardiomyopathy.
