Authors report on preliminary results of cerebral vasoreactivity-tests performed in frame of the Debrecen Hypertension Study among hypertensive and healthy adolescents.
Investigators measured blood flow velocities before and after 30 seconds of breath holding using transcranial Doppler sonography.
Blood flow velocities at rest were significantly higher in the hypertensive that in the healthy adolescent group. Breath holding induced less intensive cerebral vasoreactivity response in the hypertensive than in the normotensive group.
It is concluded that altered arteriolar function of the cerebral arterioles can be detected already in this early stage of hypertension.
