What are Natriuretic Peptides?
Natriuretic peptides are substances measurable in the blood stream which can be used to diagnose and monitor disease. Natriuretic peptides are released from the myocardium in response to fluid overload. The two main natriuretic peptides used in clinical practice are amino-terminal pro-B-type natriuretic peptide (NT-proBNP) and B-type natriuretic peptide (BNP).
