摘　　要：目的:探讨超声检查对原发性高血压患者肾动脉血流动力学及动态血压变异性(BPV)评价的临床意义。方法:选取2017年6月至2018年2月期间接受治疗的原发性高血压患者140例作为观察组,根据病程的不同将140例原发性高血压患者分为高血压组和前期高血压组,另选取同期在我院体检结果为健康的志愿者50例为对照组。比较观察组和对照组的舒张期最低血流速度(Vmin)、收缩期最大血流速度(Vmax)、收缩期血流峰速加速时间(AT)、阻力指数(RI),比较高血压组和前期高血压组的BPV相关指标。结果:观察组叶间动脉(IRA)和段动脉(SRA)中的Vmin、Vmax低于对照组(P <0. 05),PI高于对照组(P <0. 05),两组的AT比较差异无统计学意义(P> 0. 05)。高血压组的日间收缩压、日间舒张压、日间脉压、夜间收缩压、夜间舒张压、夜间脉压均高于前期高血压组(P <0. 05)。结论:原发性高血压患者肾动脉Vmin、Vmax降低,而PI升高,且BPV指标改变明显,彩色多普勒超声检查和BPV监测对可有效评估患者肾脏损伤情况,具有一定的诊断价值。Objective:To investigate the clinical significance of ultrasonography in the evaluation of renal artery hemodynamics and ambulatory blood pressure variability(BPV)in patients with essential hypertension.Methods:140patients with essential hypertension treated in our hospital from June2017to February2018were selected as the observation group.The140cases of essential hypertension were further divided into hypertension group and early hypertension group by the different course of disease,and50cases of healthy volunteers in the same period were selected as the control group.The lowest diastolic velocity(Vmin),peak systolic blood flow velocity(Vmax),peak velocity acceleration time(AT)and resistance index(RI)were compared between the observation group and the control group,and the BPV-related indexes of the hypertension group and the early hypertensive group were compared.Results:The Vmin and Vmax of the interlobar artery(IRA)and the segmental artery(SRA)in the observation group were significantly lower than those in the control group(P<0.05),and the PI in the observation group was significantly higher than that of the control group(P<0.05).There was no statistical difference in the AT between the two groups(P>0.05).The daytime systolic pressure,daytime diastolic pressure,daytime pulse pressure,night systolic pressure,night diastolic pressure and night pulse pressure in the hypertension group were significantly higher than those in the early hypertension group(P<0.05).Conclusion:The levels of Vmin and Vmax in patients with essential hypertension are significantly decreased,while the PI increase and the BPV index change obviously.The color Doppler ultrasonography and BPV monitoring can effectively evaluate the renal injury of the patients,and has certain diagnostic value.
