Methods The 80 cases undergoing coronary angiography (CAG) in our hospital were collected and divided into two groups according to the result of CAG, which were the CAE group and the normal group. Each group had 40 cases. And each group was divided into two sub-groups, which were A1 sub-group (18 cases, simple CAE), A2 sub-group (22 cases, CAE combined little plaque), B1 sub-group (25 cases, coronary artery completely normal), B2 sub-group (15 cases, simple little plaque). The plasma levels of insulin, MMP-9 and TIMP1 were detected and compared among all groups and sub-groups. The correlations of plasma insulin, MMP-9 and TIMP1 were analyzed. The risk factors of CAE were analyzed by multiple Logistic regression analys
