Objective To study the microcosmic differentiation of phlegm-retention syndromes of coronary heart disease.-Methods The clinical epidemiological investigation method was applied to observe the TCM syndrome distribution of coronary heart disease and to analyze the relation between the phlegm-retention syndrome of coronary heart disease and the blood sugar

insulin

blood fat and hemorheology indices.Results The abnormal blood fat was proved to be the material base of the syndrome of phlegm-retention in heart vessels;the abnormal hemorheological index was proved to be the material base of the syndrome of phlegm-retention obstruction.The insulin resistance existed in all syndromes of coronary heart disease

and the gradual aggravation tendency was from no phlegm-retention to phlegm-retention in heart vessels and to phlegm-retention obstruction.-Conclusion The phlegm-retention syndromes of coronary heart disease are closely related to the abnormal blood fat and hemorheology and the insulin resistance.
