Objective To observe the relationship between TCM Syndrome-type and insulin resistance (ISR) in coronary heart disease (CHD). Fifty patients were divided into 3 groups according to the Syndrome Differentiation-typing in TCM

the Heart blood stasis (HBS) Syndrome group

the Phlegm-Turbid stagnation (PTS) Syndrome group and both Qi-Yin Deficiency (QYD) Syndrome group. The fasting blood glucose (FBG)

fasting blood insulin (Ins)

insulin antibody (IAA)

islet cell antibody (ICA)

glutamic acid decarboxylase antibody (GADAb) and related blood lipid parameters in patients were determined and insulin sensitive index (ISI) was calculated simultaneously. Then the above-mentioned data were compared with those determined in 20 healthy control subjects. The levels of FBG and Ins in CHD group were higher than those in the healthy control group significantly (P<0.05)

but ISI level was obviously lower (P<0.01). Moreover

the positive percentage of IAA (40%) was higher in CHD group than that in the control group (5%) significantly (P<0.01). Comparison between the 3 TCM Syndrome-type groups and the control group showed that ISI level in HBS and PTS group was obviously lower than that in the control and the QYD (P< 0.05) respectively

and the IAA positive percentage in the former 2 groups (50%

47.37%) was higher than that in the latter two(5%

P<0.01 and 15.38%

P<0.05) markedly. While Ins level increased only in the HBS group (P<0.05). Besides

patients of HBS and PTS Syndrome were accompanied by lipid metabolic disturbance. ISR presents in part of CHD patients particularly in those with HBS and PTS Syndrome

which was partly due to the existence of serum IAA in patients.
