What is the Origin of Atrial Natriuretic Peptide?

The term's origin is descriptive, combining its site of secretion and its primary action: atrial refers to the heart chambers where it is produced, natriuretic denotes its action of promoting sodium excretion in the urine, and peptide identifies its chemical structure as a chain of amino acids. ANP was first isolated in the early 1980s from atrial muscle cells, fundamentally changing the understanding of the heart as an endocrine organ. Its discovery established the heart's direct role in systemic fluid homeostasis, extending its function beyond simple mechanical pumping.

What is the Mechanism of Atrial Natriuretic Peptide?

The release of ANP is stimulated by increased atrial stretch, which occurs in conditions of hypervolemia or hypertension. Upon secretion, ANP acts directly on the kidneys, enhancing the excretion of sodium and water by inhibiting their reabsorption in the renal tubules. This natriuretic and diuretic effect is coupled with vasodilation, which collectively decreases systemic vascular resistance and reduces extracellular fluid volume. Additionally, ANP antagonizes the renin-angiotensin-aldosterone system (RAAS), further promoting blood pressure reduction and influencing lipid and glucose metabolism by increasing adiponectin levels.

Atrial Natriuretic Peptide

Meaning

Atrial Natriuretic Peptide (ANP) is a potent, protein-based hormone secreted primarily by the cardiac atria, functioning as a key regulator of body fluid and electrolyte balance. This cardiac hormone is integral to the endocrine function of the heart, acting as a natural counter-regulatory mechanism to systems that raise blood pressure. Clinically, elevated ANP levels can serve as a valuable diagnostic biomarker for acute stages of heart failure, reflecting the degree of atrial stretch. ANP is also known by several aliases, including Atrial Natriuretic Factor and Atriopeptin.
