Cardiovascular therapy in patients with renal insufficiency

Chronic renal failure and arterial hypertension run in parallel. New goal blood pressure levels have been established in 130/85 mmHg and 125/75 mmHg depending on the level of proteinuria being below or above 1 g/day.New and lower threshold BP (>130/85 mmHg) to initiate pharmacologic therapy are required in the presence of renal failure in order to facilitate the strict BP control that is required.Renal insufficiency is accompanied since its initial stages by a marked increase in cardiovascular risk and serum creatinine, its estimated clearance and the presence of proteinuria are very powerful predictors of a bad cardiovascular outcome. Hence, the need to consider that both renal and cardiovascular protection are obtained with such a strict BP control which, otherwise seems to require blockade of angiotensin II effects when proteinuria above 1g/day is present.Prevention of renal failure related to elevated blood pressure requires of strict blood pressure control, usually obtained with combination of two or more antihypertensive agents, one of them capable of blocking angiotensin II. Besides this, strict control of associated cardiovascular risk factors is also required.
