To study the correlations between pathogenesis physical and chemical examination results and phlegm-damp pattern of coronary heart disease (CHD),and its importance for diagnosis of phlegm-damp pattern of CHD.Methods:Questionnaire of physical and chemical indicators of phlegm-damp pattern of CHD was developed,and questionnaire survey on the spot was conducted by Delphi method.Based on expert questionnaire results,evaluation function was constructed based on principal component analysis to determine the weight of physical and chemical indexes of phlegm-damp pattern of CHD.Results:The weight sequence of physical and chemical indexes of phlegm-damp pattern of CHD was as follows:ultrasonic cardiogram (0.188)>coronary angiogram (0.161)>blood sugar (0.142)>inflammation factors (0.118)>CRP (0.108)>blood lipids (0.103)>HCY (0.090)>lipoprotein (0.076)>uric acid (0.015).Conclusion:Ultrasonic cardiogram,coronary angiogram,blood sugar,inflammation factors,CRP,blood lipids account for 80% of weight of physical and chemical index of phlegm-damp pattern of CHD,which has great significance in the diagnosis of phlegm-damp pattern of CHD.
