Question

Is BNP always elevated in heart failure?

Answer 1

Brain natriuretic peptide:

1. BNP or Brain natriuretic peptide or B-type natriuretic peptide is a hormone produced by the heart.
2. Normally, the amount of BNP in the bloodstream is very low.
3. If there is an increase in the amount of BNP in the blood, it indicates that the heart is not functioning properly as in the case of heart failure.
