Progression of renal failure and hypertensive nephrosclerosis.
Data provided by end-stage renal disease (ESRD) registries document a progressive and striking increase in the incidence of hypertension-related ESRD over the years, and its prevalence supports the classic statement that the kidney may be a victim of hypertension. Two clinical conditions should be considered separately when the role of hypertension in progressive renal disease is discussed: (a) hypertension and primary renal disease and (b) progressive renal disease in essential hypertension. The appearance of systemic hypertension is one of the major risk factors for the progressive deterioration of primary renal disease both in experimental models and in humans. Strict blood pressure control is able to significantly reduce the disease progression to renal failure. Angiotensin-converting enzyme inhibitors probably show a better nephroprotective action than other antihypertensive agents. Long-lasting hypertension may induce ESRD in some patients through hypertensive nephrosclerosis. In many cases of progressive renal disease associated with essential hypertension, particularly in elderly Caucasians, atheromatous renovascular disease via renal artery stenosis and/or cholesterol microembolization represent the main cause of ESRD.
