title: Renal function in hypertension.
abstract: Hypertension certainly accelerates the age-related changes in renal structure and function, mainly in the glomerulus. Both sodium handling and the renin-angiotensin system are involved in the aging process. Among the available classes of antihypertensive agents, the eventual deterioration of renal function induced by angiotensin-converting enzyme inhibitors in bilateral stenosis and stenosis of a single functioning kidney suggests that changes in glomerular pressure may participate in the changes of renal function. In essential hypertension and other conditions, it is possible that at a certain stage an increase in intraglomerular capillary pressure plays a role in the acceleration of the loss in renal function. As a consequence, it is proposed that in treating hypertension we should aim at reducing systemic blood pressure together with an attempt to reduce intraglomerular pressure using agents that act predominantly on post-glomerular resistance in order to have renal protection.
