Microalbuminuria.

The capacity of microalbuminuria to predict an increased cardiovascular and renal risk is well established in diabetic patients, as well as in essential hypertensive patients and in general population. Detection of microalbuminuria could then be relevant to select specific therapeutic strategies for reducing or preventing cardiovascular events in patients with essential hypertension. Microalbuminuria is detectable in almost 40% of the population with established hypertension, particularly in those patients not controlled satisfactorily with medical therapy. Albuminuria may represent a marker of renal damage and cardiovascular risk in essential hypertension. Microalbuminuria seems to represent a simple and reproducible method to better define cardiovascular risk profile in the hypertensive patient and to stratify the prognosis in relation to renal and cardiovascular risk. ACE-inhibitors and more recently angiotensin II receptor antagonists seem to exhibit a more market capacity to reduce microalbuminuria in patients with essential hypertension or diabetes mellitus. Determination of this parameter in daily clinical practice could facilitate the stratification of risk as well as the choice of therapy in essential hypertensive patients.
