Their general data, biochemical indices, EAT thickness, right common carotid artery elasticity indices, and IMT were compared. The correlations of EAT thickness with right common carotid artery elasticity indices and IMT were studied by Pearson’s analysis. The predictive values of EAT thickness and IMT for CHD were analyzed by receiver operating characteristic curves.Results: With increasing number of diseased branches, EAT thickness, stiffness parameters β (β), strain elastic modulus (Ep), pulse wave velocity β (PWV-β) and IMT increased, arterial compliance (AC) decreased (P< 0.05), but argumentation index (AI) did not change significantly. EAT thickness had significant positive correlations with β, Ep, PWV-β and IMT, negative correlation with AC, and no significant correlation with AI. The areas under the curves of EAT thickness and IMT for predicting CHD were 0.806 and 0.784, respectively.Conclusion: EAT thickness is significantly correlated with right common carotid artery elasticity and IMT in middle-aged and elderly patients with CHD, and EAT thickness and IMT have high predictive values. The three indices are crucial for CHD diagnosis.Keywords: ultrasound, coronary heart disease, epicardial adipose tissue, right common carotid artery elasticity, intima-media thickness
