Abstract: Objective To investigate the relationship between carotid intima-media thickness (IMT)and plaque extent of carotid artery with coronary heart disease (CHD).Methods 131 inpatients were divided into 3 groups,in which 54 cases of coronary heart disease group,46 cases of risk group with coronary heart disease,31 cases of control group.The carotid wall IMT,plaque length and thickness was measured by Color Doppler ultrasound.The obtained data using SPSS 17.0 software for statistical processing.Results Carotid intimal thickening and the incidence had no significant difference between the group of coronary heart disease and risk group with coronary heart disease risk( all P > 0.05),carotid artery IMT and incidence rate between the above two groups and the control group had statistical differene( t =3.26,3.48,all P < 0.05 ),and the three groups of carotid artery plaque score and plaque classification were statistically significant( F =4.28,P < 0.05 ).Conclusion Carotid IMT and plaque formation was the independent risk factor of CHD,and it could predict the occurrence and development of CHD,especially in carotid artery plaque specificity is higher,in the primary hospital could be used as the auxiliary examination method of CHD.
