Value of ultrasonography on atherosclerosis of carotid artery in hypertensive patients

Objective: To evaluate ultrasonography in the detection of atherosclerotic lesions of the carotid artery in hypertensive subjects.Methods: The carotid artery hypertensive patients of 158 and 122 controls was examined by ultrasonography.The bores,intra-medial thickness(IMT),PSV,EDV and RI of the carotid artery were measured and the atherosclerotic plaques were observed by gray-scale imaging,color and spectral Doppler respectively.Results: There was significant difference between the group of hypertension and the control in IMT,bores and RI(P<0.05 to P<0.001).The incidence of plaques in the group of hypertension was higher than that in the group of control(P<0.005).Conclusions: Ultrasonogrphy plays an important role in the early diagnosis of atherosclerosis,and follow-up of artery lesions change,for patients with hypertension.
