natriurettici
Natriuretic peptides are a group of peptide hormones that play a role in regulating blood volume, blood pressure, and cardiovascular homeostasis. The primary natriuretic peptides in humans are atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP), and C-type natriuretic peptide (CNP). These peptides are synthesized and secreted by cardiac muscle cells and vascular endothelial cells, respectively, in response to mechanical stretch and increased pressure within the heart and blood vessels.
ANP is primarily released from the atria of the heart in response to atrial distension, which occurs
The main actions of natriuretic peptides include promoting the excretion of sodium (natriuresis) and water (diuresis)
Elevated levels of BNP are commonly used as a biomarker for diagnosing and assessing the severity of
