Abstract:
Objective:Use transcranial Doppler ultrasound(TCD)to investigate cerebrovascular hemodynamic changes in patients with essential hypertension and provide clinical evidence for prevention of stroke.Methods:2 025 individuals who joined in physical examination were randomly selected and classified into two groups as hypertension group of 892 cases and control group of 1 133 cases.Hypertesion group is divided into 3 subgroups as normal hypertension group,complicated with glucose or lipid metabolism disorder groups.The main observational parameters through their TCD tests were systolic blood flow velocity(Vs),diastolic blood flow velocity(Vd),mean velocity(Vm),resistant index(RI),pulsatility index(PI).Results:(1)The basilar artery blood flow velocity(Vs,Vm, Vd)of patients with essential Hypertension were significantly lower than control group,Vd of middle cerebral artery decreased in hypertensive patients.On the other hand,RI and PI of the patients were higher than control group(P
