WebbAnesthesiology September 2006, Vol. 105, 599–612. Vasopressin, synthesized in the hypothalamus, is released by increased plasma osmolality, decreased arterial pressure, … WebbNeurohumoral vasoconstrictor systems are activated in heart failure and influence left ventricular function by modifying pre- and afterload. The renin-angiotensin system, sympathetic nerve activity and vasopressin have all been implicated as mechanisms of vasoconstriction.

The physiologic stimulus for secretion of vasopressin is increased osmolality of the plasma, monitored by the hypothalamus. A decreased arterial blood volume , (such as can occur in cirrhosis , nephrosis and heart failure ), stimulates secretion, even in the face of decreased osmolality of the plasma: it supersedes … Visa mer Human vasopressin, also called antidiuretic hormone (ADH), arginine vasopressin (AVP) or argipressin, is a hormone synthesized from the AVP gene as a peptide prohormone in neurons in the hypothalamus, … Visa mer Vasopressin is used to manage anti-diuretic hormone deficiency.
