Correlation between Carotid Atherosclerosis and Coronary Heart Disease

Objective :Using the ultrasound to examine the degree of carotid atherosclerosis in patients with coronary heart disease,and to determine its correlation with coronary atherosclerosis and its predictive value for coronary heart disease(CHD). Methods :106 cases of hospitalized patients suspected coronary heart disease with coronary angiography were selected,and according to the results of coronary angiography were divided into four groups :control group,single lesion group,double lesions group and multiple lesions group. Application of ultrasound was used to measure the IMT in carotid artery bifurcation and internal carotid artery,at the same time to observe atherosclerosis plaque size,location,quantity,and the nature of the plaque,etc. Results :Carotid artery IMT values and carotid artery atherosclerosis plaque integral were significantly different among groups. The multivessel lesions group was higher than single lesion group. Integral and carotid artery bifurcation coronary artery IMT values had negatively significant correlation. Conclusions :Carotid artery IMT and plaque of atherosclerosis have good predictive value,and can be used as important predictors of coronary atherosclerosis.
