Does acute orthostatic hypotension affect cerebral autoregulatory capacity in elderly normotensive and previously treated hypertensive subjects?
Elderly individuals, regardless of treated hypertension status, maintain cerebral autoregulation during acute orthostatic hypotension.
Despite reduced CO(2) reactivity, elderly normotensive and previously treated hypertensive subjects retain cerebral autoregulatory capacity in response to acute orthostatic hypotension.
Lipsitz et al. (Tue,) studied this question.
