Blood Pressure Elevation Established as Risk for Kidney Failure

Baltimore--Elevated blood pressure has now definitely been shown to be a risk factor for kidney failure, according to a multicenter study supported by the National Institutes of Health.

Elevated blood pressure, referred to as hypertension, has long been recognized as a risk factor for stroke and heart disease. The association between severely elevated blood pressure and poor kidney function has also been long appreciated. It has not been proven whether or not the consequences of blood pressure elevation that is not severe could result in kidney failure.

When the kidney fails to function, the poisons of body metabolism are not cleared, and, therefore, build up in the blood stream. The accumulation of these chemicals is eventually fatal unless the patient receives dialysis or kidney transplantation.
