冠心病患者下肢动脉硬化的超声检测及意义

Ultrasonography and significance on artherosclerosis of lower extremity in patients with coronary artery disease

目的:应用二维及彩色多普勒超声方法对已确诊冠心病患者下肢动脉疾病情况进行分析探讨,了解下肢动脉硬化与冠心病之间关系。方法:采用高频探头对临床已确诊的冠心病患者136例(冠心病组)及非冠心病对照者100例(对照组)进行分析对比,观察下肢动脉粥样硬化程度(包括内中膜厚度、有无斑块形成)。结果:冠心病组与对照组相比,冠心病组下肢动脉硬化斑块检出率明显高于对照组,为70.6%vs12.0%(P<0.01),并随冠状动脉病变程度增加下肢动脉硬化斑块检出率明显增加,多支病变组下肢动脉粥样硬化斑块发生率高于单只病变组,为87.5%vs46.4%(P<0.01)。结论:下肢动脉硬化与冠心病之间存在一定相关性,下肢动脉硬化对冠心病发生及病变程度的预测有重要意义,在一定程度上反映冠状动脉粥样硬化的有无和病变程度。

Objective To investigate the condition of lower extremity artery in patients with coronary artery disease by using 2D and color Doppler method, and understand the relationship between atherosclerosis of lower extremity and coronary artery disease. Methods To observe atheroselerotic degree of Artery of lower extremity （among which include intima tunica media thickness, had plaque or none）, probed into high frequency to analyze and contrast between 136 patients with coronary artery disease who is already clinically diagnosed as well as 100 control group patients without coronary artery disease. Results Compared patients with coronary artery disease and control group, sickness rate of atherosclerosis of lower extremity was higher than control group , following increase of pathological changes degreet of coronary artery disease, Intima tunica media pathological changes of Artery of lower extremity and plaque detection rate were increasing. Conclusions Existed invariably dependability between atherosclerosis of lower extremity and coronary artery disease , atherosclerosis of lower extremity had important sense as for prognostication of coronary artery disease genesia and pathological changes degree, in invariably degree, it reflected the diagnosis of coronary atherosclerosis and pathological changes degree.
