Correlation analysis between both carotid atherosclerotic plaque and carotid artery intimia-media thickness with coronary heart disease

Objective To investigate the relationship between carotid artery plaque,Intimia-media thickness and coronary heart disease.Methods One hundred and forty-five cases of suspected patients with CHD had to do carotid artery ultrasounic examination,observation and measurement of IMT and coronary angiography.Results We found IMT in Non-CHD group and CHD group were 0.75±0.10mm and 0.99±0.29mm.The prevanlence rate of atherosclerotic plaques were 25%(11/44) and 77.22%(78/101) and there were significant difference between the two groups,P0.005.Hard plaque group CHD highest incidence of 96.55%,followed by soft plaque group was 83.33 %,the lowest non-plaque group 41.07%.There were significant difference between every two groups,P0.005.An IMT ≥ 0.85mm or the occurrence of atherosclerotic plaques could predict the presence of Coronary Heart Disease with a sensitivity of 77.22%,specificity of 81.81%,and a positive predictive value of 83.72%.Conclusion There was close relationship between both carotid atherosclerotic plaque and the increased intimia-media thickness with coronary heart disease.Carotid artery ultrasounic examination could help to predict the incidence of coronary heart disease.
