The kidney and arterial hypertension.

It has been known for some time that a relationship exists between the kidney and blood pressure. The renal origin of arterial hypertension has been demonstrated in different animal models resembling human hypertension, with data from humans seeming to confirm this hypothesis. On the other hand, the renal vasculature also suffers the consequences of arterial hypertension, and renal insufficiency can develop as a result of elevated blood pressure levels. Antihypertensive therapy can prevent the development of renal damage secondary to hypertension. For example, calcium antagonists possess specific renal effects that not only facilitate their antihypertensive capacity but also protect the kidney from the development of renal failure.
