Elevated atrial natriuretic factor in the plasma: cause or effect in "idiopathic orthostatic hypotension"?
A patient with idiopathic orthostatic hypotension exhibited low activity of norepinephrine and renin in plasma which failed to respond to standing. Levels of atrial natriuretic factor were inappropriately elevated and failed to fall on standing. The possible role of the atrial natriuretic factor in idiopathic orthostatic hypotension is discussed.
