Abstract/OtherAbstract:
Atrial natriuretic factor 95-126 [ANF (95-126)] is a novel 32 amino acid peptide which is thought to originate from the kidney. The systemic hemodynamic and renal effects of equimolar doses of intravenous synthetic ANF (95-126) and synthetic alpha ANF (99-126) were examined in normal dogs (n = 6) and in dogs with an arteriovenous (AV) fistula and chronic compensated high-output heart failure (n = 5). ANF (95-126) and alpha ANF (99-126) were infused at 5 and 10 pmol/kg/min for 75-min periods each. In the normal and AV fistula dogs the two peptides similarly decreased mean arterial pressures and right atrial pressures (P less than .05). Creatinine clearance and urinary volume excretion increased (P less than .05) in the normal dogs with both peptides, but only ANF (95-126) produced significant elevations (P less than .05) of these two parameters in the AV fistula animals. With the highest infusion dose, ANF (95-126) increased urinary sodium excretion to at least twice the levels observed with alpha ANF (99-126) in both groups of dogs (P less than .05). The decreases in plasma renin and aldosterone were comparable for the two peptides in both groups of animals. These results indicate that ANF (95-126) is more potent than alpha ANF (99-126) for the promotion of a natriuresis, particularly in AV fistula dogs with compensated high-output heart failure, in which the sodium excretory actions of alpha ANF (99-126) were attenuated markedly.
