An Ultrasonic Analysis on Carotid of 332 Patients with Hypertension

Objective: To investigate morbility characteristics of carotid atherosclerosis in essential hypertension patients,and to assess the value of ultrasound examination in this disease.Methods: Three hundreds and thirty-two essential hypertension patients were divided into three groups according to their blood pressure levels: group 1(70 cases),group 2(131 cases) and group 3(131 cases).Carotid color doppler ultrasonography was performed on the patients and 32 people with normal blood pressure.Inner membrane and media thickness(IMT) of carotid and inner diameter of it were detected.Plaque development and carotid artery stenosis status were observed.Results:Carotid artery IMT of essential hypertension patients was thicker than that of control cases,and the difference was significant(P0.01).Inner diameters of carotid artery of hypertension patients were bigger than those of control cases,and the difference was significant(P0.05).The detection rates of plaques in carotid artery of hypertension patients were much higher than those of control cases(P0.01).The plaques usually occurred on the fork part of carotid artery.Conclusions: Color Doppler ultrasound helps to understand the degree of carotid atherosclerosis of essential hypertension patients,and it is an important method for early discovery and screening of high-risk patients with cardio-cerebrovascular disease.
