Types of biomarkers for measuring heart failure disease using peripheral blood include HF inflammation biomarkers (C reactive protein (CRP) and interleukin 6 (IL-6), HF myocyte injury biomarkers (cardiac-specific troponin I (CTnI), and creatine kinase-MB (CK-MB), and HF myocyte stress biomarkers (B-type natriuretic peptide (BNP) and ST2 proteins). This evidence concerns the gene TNNI3 and hydrops fetalis.
