What is the Meaning of NT-proBNP?

NT-proBNP, or N-terminal pro-B-type Natriuretic Peptide, is an inactive N-terminal fragment that is stoichiometrically co-released with the active hormone B-type Natriuretic Peptide (BNP) from ventricular cardiomyocytes. This peptide fragment is a clinically indispensable biomarker utilized primarily for the diagnosis, prognosis, and severity assessment of congestive heart failure. Its circulating concentration is directly proportional to the degree of myocardial volume expansion and wall stress.

What is the Origin of NT-proBNP?

The acronym NT-proBNP is derived from its chemical structure: the N-terminal fragment of the prohormone for B-type Natriuretic Peptide. The original name BNP stems from its initial isolation from porcine brain tissue, although its primary and most significant source is the cardiac ventricles. Its clinical utility is a product of modern cardiovascular endocrinology, recognizing the heart as a crucial endocrine organ.

What is the Mechanism of NT-proBNP?

Increased ventricular pressure and stretch stimulate the synthesis and secretion of the precursor proBNP, which is subsequently cleaved by a protease into the biologically active BNP and the inactive NT-proBNP fragment. BNP acts as a counter-regulatory hormone, promoting vasodilation and natriuresis to reduce blood volume and cardiac preload. Because NT-proBNP exhibits a significantly longer plasma half-life than BNP, it accumulates in the circulation, serving as a stable and measurable indicator of chronic cardiac neurohormonal activation.
