WebA high BNP blood test result may indicate worsening heart failure. BNP is a protein that increases in the presence of heart failure. BNP stands for B-type natriuretic peptide, which is a type of protein that increases in the body when heart failure worsens. BNP is measured using a blood test. WebNatriuretic hormones are peptides that stimulate the kidneys to excrete sodium—an effect opposite that of aldosterone. Natriuretic hormones act by inhibiting aldosterone release and therefore inhibiting Na + recovery in the collecting ducts. If Na + remains in the forming urine, its osmotic force will cause a concurrent loss of water.
