Natriuretic Peptides (BNP and NT-proBNP)

Natriuretic peptides (NPs) are markers of hemodynamic stress on the heart, denoting the neurohumoral activation of the myocardium. BNP and NT-proBNP are produced in a 1:1 ratio when the left ventricle is stretched due to hemodynamic pressure. Elevated levels of either of these peptides are associated with heart failure, and both are equally useful as an aid in the diagnosis of congestive heart failure (CHF).
