Literature study on distribution of TCM syndrome of chronic pulmonary heart disease.

Objective:To study the distribution ofTCM syndrome ofchronic pulmonary heart disease(CPHD) based literature data.Methods:Combinating computer index and man-made index, by way ofliterature database index on internet, the literature data ofCPHD syndromes were gathered from 1977 to 2008.The data were analyzed by description, logistic regression and clustering analysis.Results:251 items of48 documents were used for analysis.The results indicated that the incidence frequency ofsome syndromes ofCPHD were higher in the distribution ofTCM syndrome, they were syndrome ofdeficiency ofqi ofthe lung and kidney, syndrome ofphlegm and heat stagnating the lung, syndrome ofheat-phlegm stagnating the lung, syndrome ofobstruction ofpericardium by phlegm, syndrome ofedema due to yang deficiency, syndrome ofdeficiency ofqi and stagnation ofblood, syndrome ofcollapse ofyang.Combined with cluster analysis, 7 syndromes were screened out as the clinical syndromes.They were syndrome ofdeficiency ofqi ofthe lung and kidney, syndrome ofphlegm and heat stagnating the lung, syndrome ofheat-phlegm stagnating the lung, syndrome ofobstruction ofpericardium by phlegm, syndrome ofedema due to yang deficiency, syndrome ofstagnation ofblood, syndrome ofcollapse ofyang.Meanwhile, the main symptoms and the sub-symptoms ofthe primary syndromes were screened out by professional knowledge and statistical analysis.Conclusion:Based on frequency and cluster analysis,7 syndromes were selected as main syndromes ofCPHD, they were syndrome ofstagnation ofthe lung by phlegm and heat, syndrome ofheat-phlegm stagnating the lung, syndrome ofobstruction ofpericardium by phlegm, syndrome ofdeficiency ofqi ofthe lung and kidney, syndrome ofedema due to yang deficiency, syndrome ofcollapse ofyang, syndrome ofstagnation ofblood.The characteristic ofthe syndromes were analysised, and that would provide references for the next research.
