摘要
目的探讨冠心病时外周大动脉粥样硬化病变程度及两者的关系。方法90例冠心病患者(冠心病组)根据冠状动脉造影显示的冠状动脉狭窄程度分为3个亚组,采用高频超声测量颈总动脉和股动脉的内-中膜厚度(IMT)、探测斑块发生率、相关物理性状和血流动力学环境参数,统计学处理各数据,并对结果进行对比分析。结果冠心病组患者颈总动脉和股动脉的IMT、粥样硬化斑块检出率、数目及其积分均随着冠状动脉狭窄程度的增加而增加;颈总动脉部分物理性状及血流动力学环境参数也随之发生相应的变化。结论冠心病病变严重程度与颈总动脉和股动脉粥样硬化程度之间有一定的关联。
Objective To assess the correlation between coronary heart disease and common carotid artery and femoral artery atherosclerosis with two-dimensional color Doppler ultrasound（2D-CDUS）.Methods Ninety patients with coronary heart disease were divided into three subgroups according to the extent of coronary artery stenosis observed with coronary angiography,and 50 normal subjects were taken as normal group.Ultrasound examination with high-frequency linear array probe was performed to measure IMT of common carotid and femoral artery in order to observe the plaque and extent of stenosis,the formation of blood dynamics,physical characteristics and hemodynamic environmental parameters.Results Among the coronary disease groups,common carotid artery and the femoral artery IMT,atherosclerotic plaque in the number,rate and all points increased along with the degree of coronary artery stenosis increasing.Physical characteristics and its hemodynamic environmental parameters had some changes with the increase of atherosclerosis.Conclusion The atherosclerosis of common carotid artery and the femoral artery are closely related with coronary atherosclerosis.
