Evidence for a Prolonged Biological Half-Life of Na 22 in Patients with Hypertension

Abstract
The biological half-life of Na 22 was found to be significantly longer ( p <0.01) in seven hypertensive adults than in eight normotensive adults on equivalent NaCl intakes. Calculations based on approximations of leanbody mass suggest that the hypertensive subjects may have a larger sodium pool to explain this disparity.
