Atrial natriuretic hormone

ANF — Atrial natriuretic factor is called the hormone of the heart. It is a protein-based hormone, secreted and released by the cardiac muscle cells. The synthesized hormones are released into the atrium in counter to the high blood pressure through the heart muscle cells. ANF is an important vasodilator, which is involved in the homeostatic regulation of body fluids, sodium, atrial natriuretic hormone, potassium and fats in the adipose atrial natriuretic hormone.

Atrial natriuretic hormone

Federal government websites often end in. The site is secure. Atrial natriuretic peptide ANP is a cardiac hormone that regulates salt-water balance and blood pressure by promoting renal sodium and water excretion and stimulating vasodilation. ANP also has an anti-hypertrophic function in the heart, which is independent of its systemic blood pressure-lowering effect. In mice, ANP deficiency causes salt-sensitive hypertension and cardiac hypertrophy. Recent studies have shown that ANP plays an important role in regulating vascular remodeling and energy metabolism. ANP and related peptides are used as biomarkers for heart disease. Recombinant proteins and small molecules that enhance the ANP pathway have been developed to treat patients with HF. In this review, we discuss the role of ANP in cardiovascular biology and disease. Maintaining salt-water balance is of fundamental importance for all animals. The discovery of the natriuretic activity in rat atrial extracts by de Bold et al. The responsible molecule later was found to be atrial natriuretic factor ANF , also called atrial natriuretic peptide ANP de Bold, Under high blood volume and pressure, heart muscle cells release ANP into the circulation. In the kidney, ANP enhances salt and water excretion. In the blood vessel, ANP promotes vasodilation.

The cardiocytes of mammalian cardiac atria contain granules very similar to those in endocrine cells 1,2. The number of these atrial granules is related directly to salt loading and blood volume 3.

This observation led to the postulation that an additional NH is released from the intestine in response to salt intake Plasma atrial natriuretic peptide in cardiac disease and during infusion in healthy volunteers. About journal About journal. Hausmaninger C. Page E. Endocrinology —6. The discoveries that the natriuretic peptides play a role in lipid mobilization within human white adipose tissue, skeletal muscle fat oxidation, and dissipation of energy in brown adipose tissue all point to the fact that the natriuretic peptides are possibly associated with glucose homeostasis, fatty acid metabolism, and insulin sensitivity.
