目的通过经颅多普勒观察具有家族性高血压病高危人群脑血管结果分析,评价经颅多普勒对家族性高血压病高危人群早期高血压具有的诊断价值。方法利用经颅多普勒检测186例家族性高血压病高危人群与100例健康人的颅内动脉收缩期血流速度(Vp)、舒张期血流速度(Vd)、收缩期平均血流速度(Vm)、血管搏动指数(PI)和血管阻力指数(RI)的改变及频谱的形态进行对比综合分析。结果186例家族性高血压病高危人群中脑血管痉挛管及弹性减退(脑动脉硬化)均为98例,均为占总病例数的52.78%;70例脑供血不足,占总例数中的37.63%。与对照组相比差异有统计学意义(P<0.05)。结论经颅多普勒可用于家族性高血压高危人群早期高血压诊断和对脑血管状况进行评价。
Objective To evaluate the value of transcranial Doppler in the early diagnosis of hypertension in high-risk population with familial hypertension by transcranial Doppler and analyze the results of cerebrovascular disease in high-risk population with familial hypertension. Methods Transcranial Doppler was used to detect the systolic blood flow velocity (Vp), diastolic blood flow velocity (Vd), systolic blood flow velocity (RV) in 186 high risk population of familial hypertension and 100 healthy subjects (Vm), vascular pulsatility index (PI) and vascular resistance index (RI) changes and the morphology of the spectrum for comparative analysis. Results A total of 98 middle cerebral vasospasm and degeneration of elasticity (cerebral arteriosclerosis) were found in 186 high risk population of familial hypertension patients, accounting for 52.78% of the total number of cases. 37.63%. Compared with the control group, the difference was statistically significant (P <0.05). Conclusion Transcranial Doppler can be used for the diagnosis of early hypertension in high-risk population of familial hypertension and evaluation of cerebrovascular status.
