To review the physiological actions, regulation, and pathophysiological significance of cardiac atrial peptides in cardiovascular and neuroendocrine systems.
Synthesized findings from pharmacological and physiological studies in experimental animals and humans examining endogenous secretion and exogenous peptide administration.
Evaluated hemodynamics, fluid distribution shifts, endocrine interactions, and central nervous system receptor activity associated with atriopeptin.
Atrial pressure serves as the primary regulator of atriopeptin secretion, eliciting marked natriuresis at pharmacological doses but modest diuresis during physiological three- to fivefold plasma elevations.
Atrial peptides induce cardiovascular changes including decreased arterial blood pressure, cardiac filling pressure, and cardiac output, alongside fluid translocation into interstitial spaces and suppression of the renin-angiotensin-aldosterone system.
Atriopeptin is widely distributed within the brain to act as a neuromodulator, while circulating peptides access cerebral pathways through circumventricular organ receptors.
