Can you tell me how nephrosclerosis lead to chronic kidney failure?

Kidney failure: The term hypertensive nephrosclerosis has traditionally been used to describe a clinical syndrome characterized by long-term essential hypertension, left ventricular hypertrophy, minimal proteinuria, and progressive renal insufficiency. All of these are signs of poorly treated hypertension. If BP is not well controlled, end stage organ damage, heart, kidney and brain damage will occur.
