Brain natriuretic peptide (BNP), also known as B-type natriuretic peptide, is a hormone secreted by cardiomyocytes in the heart ventricles in response to stretching caused by increased ventricular blood volume. [5] BNP is one of the three natriuretic peptides, in addition to atrial natriuretic peptide and C-type natriuretic peptide . [6]
N-terminal prohormone of brain natriuretic peptide (NT-proBNP or BNPT) is a 76 amino acid long protein that is cleaved from the N-terminal end of the 108 amino acid long prohormone proBNP to release brain natriuretic peptide 32 (BNP, also known as B-type natriuretic peptide). [1] [2] [3] [4]
Natriuretic peptide-binding receptors and ligand selectivity. [1] A natriuretic peptide is a hormone molecule that plays a crucial role in the regulation of the cardiovascular system. These hormones were first discovered in the 1980s and were found to have very strong diuretic, natriuretic, and vasodilatory effects.
ACB test has low specificity therefore generating high number of false positives and must be used in conjunction with typical acute approaches such as ECG and physical exam. Additional studies are required. Pro-brain natriuretic peptide: This is increased in patients with heart failure. It has been approved as a marker for acute congestive ...

It is promoted by ventricular and atrial natriuretic peptides as well as calcitonin, [2] and inhibited by chemicals such as aldosterone. Natriuresis lowers the concentration of sodium in the blood and also tends to lower blood volume because osmotic forces drag water out of the body's blood circulation and into the urine along with the sodium.
Natriuretic peptides comprise a family of 3 structurally related molecules: atrial natriuretic peptide , brain natriuretic peptide , and C-type natriuretic peptide (CNP), encoded by a gene symbolized NPPC. These peptides possess potent natriuretic, diuretic, and vasodilating activities and are implicated in body fluid homeostasis and blood ...
