Color Doppler ultrasonography for judging the carotid artery atherosclerosis in elderly patients with essential hypertension / 中国组织工程研究

ABSTRACT

A total of 160 elderly patients with Ⅰ -Ⅲ essential hypertension were enrolled in the study and examined with high-frequency color Doppler ultrasonography (America ATL Company HDI3500 type color ultrasonoscope). Common carotid artery (CCA), internal carotid artery and external carotid artery (ECA) were detected, including carotid artery intima-media thickness (CAIMT) and hemodynamic index. At the same time, 110 healthy elders were taken as contrast group. With the increased degree of hypertension, CAIMT was gradually enhanced and the most obviously in patients of grade Ⅲ hypertension. There were significant differences in grade Ⅲ, Ⅱ, Ⅰ and contrast group (P
