π« Brain Natriuretic Peptide (BNP): Despite its name, BNP is produced mainly in the ventricles (not the brain). It is secreted in response to β ventricular wall stretch and pressure overload, promoting natriuresis (NaβΊ excretion), diuresis π§, vasodilation, and suppression of the RAAS. It is a cornerstone biomarker in Heart Failure.
BNP is a key ventricular stretch hormone regulating fluid and BP homeostasis via natriuresis, diuresis, vasodilation, and RAAS inhibition. Its major clinical value is as a diagnostic and prognostic biomarker in heart failure, with NT-proBNP widely used in practice. Remember: "BNP = Bad News Peptide" when elevated π«.
