Among the various protein biomarkers for monitoring of heart diseases, cardiac troponins (cTnT, cTnI) or myoglobin (Mb) concentrations in serum remain elevated after the occurrence of an acute myocardial infarction (AMI), while early markers such as cardiac reactive protein (CRP) and both B-type natriuretic peptide (BNP) and N-terminal ProBNP show rising concentrations on the occurrence of symptoms of systemic inflammation. This evidence concerns the gene MB and myocardial infarction.
