Proteinuria and hypertension.

Albuminuria is more prevalent in patients with primary hypertension than in normotensive subjects of the general population. The presence of albuminuria predicts the presence of more severe target organ damage and is related to the risk of cardiovascular events. Preliminary results show albuminuria even in some normotensive individuals with a genetic risk of hypertension and in association with insulin resistance. While albuminuria is generally more frequent in the elderly, it is also found in young patients with mild to moderate primary hypertension. It is uncertain whether in these circumstances albuminuria indicates some "renal component" in the etiology of primary hypertension. Massive albuminuria may occur in subjects with "benign" nephrosclerosis. Whether albuminuria is a predictor of hypertensive renal damage requires further study. Albuminuria is reduced by antihypertensive treatment, but diverse effects on albuminuria are seen with different antihypertensive agents.
