Ultrasonic observation of correlation between coronary heart disease and common carotid artery and femoral artery atherosclerosis

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.
