Brain Natriuretic Peptide, HumanPrice Inquiry
BNP was primarily discovered in porcine brain, but the highest concentration of peptide is found in the heart. It is a 32 amino-acid peptide, synthesized within the ventricles in response to myocyte stretch and/or pressure overload. It is released both as an active hormone and an inactive N-terminal fragment (NT pro-BNP).
Higher BNP concentrations early after first myocardial infarction are associated with adverse left ventricular remodelling characteristics. This may help explain why BNP is such a strong predictor of outcome after myocardial infarction.

Subtle cardiac abnormalities have been described in patients with cirrhosis. Natriuretic peptide hormones have been reported to be sensitive markers of early cardiac disease. We postulate that plasma levels of N-terminal pro-atrial natriuretic peptide and brain natriuretic peptide could be used as markers of cardiac dysfunction in cirrhosis.
