摘　　要：目的:分析彩色多普勒血流成像(CDFI)在中老年高血压(EH)患者颈动脉血流动力学检测中的应用。方法:选取CDFI检查的150例中老年EH患者,并纳入高血压组,按1∶1比例筛选同期在医院行健康体检,且将有CDFI影像学资料的150名中老年健康志愿者纳入健康对照组。回顾性分析两组CDFI检查结果,比较两组颈动脉形态学及血流动力学指标。结果:高血压组颈总动脉及颈内动脉的内径(D)、颈动脉内-中膜厚度(IMT)以及阻力指数(RI)均显著高于健康对照组,差异有统计学意义(t=5.706,t=2.658,t=5.944,t=15.620,t=8.394,t=17.559;P<0.05);颈总动脉及颈内动脉的收缩期峰值流速(PSV)和最大剪切率(SR)均显著低于健康对照组,差异有统计学意义(t=3.389,t=13.325,t=18.060,t=10352;P<0.05);且不同EH分级患者颈动脉形态及血流动力学的D、IMT、RI,PSV和SR比较差异有统计学意义(F=8.902,F=112.127,F=21.968,F=87.232,F=49.280;P<0.05);经Spearman相关性分析,D、IMT及RI均与EH分级显著正相关(r=0.311,r=0.742,r=0.731;P<0.01),PSV及SR与EH分级显著负相关(r=-0.466,r=-0.642;P<0.01)。结论:EH患者CDFI所示颈动脉形态学及血流动力学参数均与病情显著相关,或可成为筛查此类患者动脉血管粥样病变的首选影像学检查手段,值得临床重视。Objective:To analyze the application of color Doppler flow imaging(CDFI)in the detection of carotid hemodynamic for middle and older aged patients with essential hypertension(EH).Methods:150 middle and old aged patients with EH who underwent CDFI examination in the hospital were enrolled in the EH group.As 1:1 ratio,another 150 middle and old aged healthy volunteers with CDFI imaging data who underwent physical examinations in this hospital during the same period were enrolled in the control group.The CDFI results of two groups were retrospectively analyzed,and the indexes of carotid morphology and hemodynamic between the two groups were compared.Results:The internal diameters(D)of common carotid artery and internal carotid artery,carotid intima-media thickness(IMT)and resistance index(RI)in EH group were significantly higher than those in control group(t=5.706,t=2.658,t=5.944,t=15.620,t=8.394,t=17.559,P<0.05).The peak systolic velocity(PSV)and maximum shear rate(SR)of common carotid artery and internal carotid artery of EH group were significantly lower than those in healthy control group(t=3.389,t=13.325,t=18.060,t=10.352,P<0.05).The differences of D,IMT,RT,PSV and SR of carotid morphology and hemodynamic among patients with different EH grades were significant(F=8.902,F=112.127,F=21.968,F=87.232,F=49.280,P<0.05).Spearman correlation analysis showed that D,IMT and RI had significantly positive correlation with EH grading(r=0.311,r=0.742,r=0.731,P<0.01),respectively,while PSV and SR had significantly negative correlation with EH grading(r=-0.466,r=-0.642,P<0.01),respectively.Conclusion:For patients with EH,all of the parameters of carotid morphology and hemodynamic that are indicated by CDFI are significantly correlative with illness condition.They might be the preferred imaging examination way for screening arterial atherosclerotic lesions of such patients.
