Study of carotid by ultrasonography in hypertension patients

Objective To discuss the characteristics of carotid morphologic and hemodynamic in patients with hypertension. Methods We performed high frequency ultrasound on carotid artery in 119 primary hypertension individuals and 34 control subjects, then analyzed the carotid morphologic and hemodynamic changes by the statistical software. Results 1.The significant difference was found in inner diameter of carotid artery in grade 3 groups compared with control cases(p0.05).The intima-media thickness (IMT) of common carotid artery(CCA) and the Crouse integration in hypertension groups were also significant higher than that in the control group(p0.05).2.There were significant differences in the peak systolic velocity and end diastolic velocity of CCA between hypertension groups and control group(p0.05). 3.Significant positive correlation between pulse pressure (PP) and IMT of CCA was found (R=0.339,p0.01). The IMT of CCA and atherosclerotic plaques presence rate in group PP≥60mmHg were significant higher than those in group PP60mmHg(p0.01). Conclusion There is significant positive correlation between hypertension and carotid atherosclerosis, furthermore, carotid atherosclerosis is correlated with different hypertension grades and the pulse pressure. High frequency ultrasound is able to reveal the condition of carotid in hypertension patients accurately.
