Key result
Infusion of atrial natriuretic factor at 0.3 and 1.0 micrograms/min significantly lowered plasma renin activity and aldosterone, while 1.0 microgram/min significantly lowered systolic blood pressure.
Why the study?
Does incremental infusion of atrial natriuretic factor affect aldosterone, renin, and blood pressure in sodium-deprived normal men?
Does incremental infusion of atrial natriuretic factor affect aldosterone, renin, and blood pressure in sodium-deprived normal men?
ANF infusion lowers blood pressure, plasma renin activity, and aldosterone levels in a dose-dependent manner at physiological and slightly elevated concentrations.
No takes yet. Share an insight, caveat, or question.
ANF effects on renin-aldosterone axis merit targeted trials in hypertension; leaves open therapeutic relevance.
Oelkers et al. (1988) studied Healthy volunteers (sodium-deprived) (n=6). Human atrial natriuretic factor-(99-126) (ANF) vs. Placebo was evaluated on Blood pressure, heart rate, plasma concentrations of ANF, aldosterone, cortisol, and plasma renin activity. Infusion of atrial natriuretic factor at 0.3 and 1.0 micrograms/min significantly lowered plasma renin activity and aldosterone, while 1.0 microgram/min significantly lowered systolic blood pressure.
