ABSTRACT
Objective To assess the cerebrovascular reactivity (CVR) in health subjects and patients with risk factors by means of transcranial Doppler ultrasonography (TCD) with breath-holding maneuver, and its association with risk factors of cerebrovascular disease.Methods The breath-holding index (BHI), which was the percentage increase in middle cerebral artery(MCA)blood flow velocity and was as index of CVR assessment, was detected during breath-holding by TCD and breath-holding technique in 137 patients with various risk-factors of cerebrovascular disease and 87 normal controls.The regression analysis was done between the CVR and risk factors.Results The mean blood velocity before (Vm) and after holding test (Vm′) were significantly lower in group with age of 20-40 years than that of the age of 41-60 and over 60 years(all P
