目的:为了解老年颈动脉粥样硬化的发生率及危险因素的关系,对133例年龄在61～92岁的患者进行颈动脉超声检查。结果:颈动脉壁内膜—中层厚度增加、斑块形成,轻度狭窄(内径减少<20％)和显著狭窄(面积减少>50％)的检出率分别为76.8％、48.1％、32.2％和1.5％。颈动脉粥样硬化与临床诊断的冠心病、脑梗塞、高血压、高血脂、糖尿病均无显著性相关。随着年龄的增加,颈动脉粥样硬化的检出率明显增加(P<0.05),病变程度也趋于加重。
OBJECTIVE: To understand the incidence of carotid atherosclerosis and the risk factors in elderly patients, 133 patients aged 61-92 years old underwent carotid ultrasonography. Results: The intima-media thickness of the carotid artery wall was 76.8%, 48.1% and 32.2% respectively with plaque formation, mild stenosis (diameter less than 20%) and significant stenosis (area less than 50%). And 1.5%. Carotid atherosclerosis and clinical diagnosis of coronary heart disease, cerebral infarction, hypertension, hyperlipidemia, diabetes were not significantly correlated. With the increase of age, the detection rate of carotid atherosclerosis increased significantly (P <0.05), and the severity of the disease tended to aggravate.
