title: [Change in the renin-angiotensin-aldosterone system in aging. 1].
abstract: Data are provided that testify to a changed reactivity of the RAAS in old age: Higher sensitivity of this system to the regulatory influences of the sympathico-adrenal and of the hypothalamus-hypophysis system as well as restriction of the functional facilities and reduction of reactivity. The obtained results indicate an aging-dependent reduction of the degree of reliability of the RAAS in stress situations.
