[The age-related characteristics of the renal circulation and kidney function in healthy subjects and hypertension patients].

A study is presented of the state of renal hemodynamics and renal function in 70 practically healthy person (age: 45-95 years) and 72 patients with hypertensive disease, grade 11 (age: 45-89 years). It was found that as distinct of the healthy, patients suffering of hypertensive disease revealed a content of blood creatinine that was directly related to the level of arterial pressure (diastolic) and an inverse relation with the level of glomerular filtration and effective renal blood circulation. The above mentioned data indicate the importance of careful control of the state of renal function during hypotensive therapy in elderly and old patients.
