The Kidney and Hypertension
From the earliest studies on kidney disease it was already apparent that the kidneys play a very important role in Controlling arterial pressure. However, the mechanism or mechanisms by which the kidney affects pressure have remained unclear even to the present. All research workers have known of the obvious possibility that renal disease might cause retention of water and salt in the body and that excess volume could drive the circulatory system toward a higher level of activity, thus causing hypertension. Yet, even Bright (1836) in his classical studies on “Bright’s disease” noted vasospastic phenomena associated with renal hypertension, leading to the suggestion that renal hypertension might result from some circulating vasoconstrictor agent.
