Pathophysiology of hypertensive renal damage

Abstract

Rived relaxing factor. Increased transit of proteinladen fluid into the mesangial space also may mediate hypertensive nephrosclerosis. Several studies have provided encouraging evidence that antihypertensive therapy, particularly with angiotensinconverting enzyme inhibitors or calcium antagonists, can slow the progression of renal damage.

Evidence from studies of renal transplant recipients and familial studies suggests a genetic component for the occurrence of hypertension and nephrosclerosis. Glomerular injury may result from glomerular hypertension caused by loss of autoregulation and afferent renal vasodilatation. Glomerular injury may be mediated by injury to endothelial cells, which, having lost their thromboresistance, may initiate intravascular coagulation and alter the balance between endothelin and endothelium-de. © 1993 by the American Journal of Hypertension, Ltd.
