Coronary heart disease (CHD) is a common clinical multiple diseases, insulin resistance (IR) and its secondary to hyperinsulinemia (HIS) is the main mechanism led to a series of metabolic disorders and cardiovascular disease, the relationship between IR and coronary heart disease research into the field of cardiovascular disease, a new research focus. Objective: To investigate the degree of coronary heart disease insulin resistance, to explore the relationship between coronary heart disease in patients with IR and coronary artery disease type and TCM sub-type. Methods: patients with coronary artery disease diagnosed by coronary angiography (CAG) 90 cases, including unstable angina (SA) 15 cases of unstable angina (UA) 38 cases of acute myocardial infarction (AMI), 37 patients; TCM syndrome type of Qi and Yin (22 cases), Qi and Blood (25 cases), blood stasis (26 cases) and the phlegm Xinmaitong (17) 4; according to the results of CAG coronary artery disease is divided into A ( 15), B (38) C (37). 18 patients with suspected coronary artery disease undergoing coronary angiography to exclude coronary heart disease as the normal control group. Measured fasting insulin (FINS), fasting blood glucose (FBG) and lipid levels, insulin resistance index Homa-IR = LN (FBG × FINS/22.5). Contrast to the normal control group with different clinical diagnosis of coronary artery disease typing, the different typing CAD group these indicators; analysis and linear regression analysis, HOMA-IR, lipids and CAD. Results: 1, AMI, UA group and normal control group, there is HIS and HOMA-IR increased (P <0.01), lower insulin sensitivity (P <0.01) in patients compared with UA and AMI group group; SA was no significant difference in group FINS and HOMA-IR with normal control group. 2, B-C in patients with coronary artery disease and normal control group compared with the presence of HIS and higher HOMA-IR (P <0.01); no significant difference between patients with type A lesions with normal control group. 3, the TCM type FINS and HOMA-IR than the normal control group higher (P <0.05), especially in the most obvious type of blood stasis (P <0.01). IR and lipid abnormalities related to HOMA-IR and BMI, CHO, TG was positively correlated with HDL was negatively correlated; HOMA-IR linear correlation with coronary heart disease. Conclusion: 1, IR and blood lipid abnormalities, is an independent risk factors for CAD. 2, IR in patients with coronary heart disease, to UA, AMI significantly with multivessel coronary artery disease, diffuse, complex trend. 3, TCM and excess \
