In medicine, brain natriuretic peptide (BNP) is a "peptide that is secreted by the brain and the heart atria, stored mainly in cardiac ventricular myocardium. It can cause natriuresis; diuresis; vasodilation; and inhibits secretion of renin and aldosterone. It improves heart function. It contains 32 amino acids."[1]
An elevated BNP can detect heart failure:[2]
| Sensitivity | Specificity | |
|---|---|---|
| BNP > 100 pg per milliliter | 90% | 76% |
| BNP > 50 pg per milliliter | 97% | 62% |
