Clinical research on common TCM syndrome of chronic pulmonary heart disease with respiratory failure

Objective:To study the distribution and main symptom characteristics of TCM syndrome of chronic pulmonary heart disease(CPHD)with respiratory failure based on multicenter clinical research.Methods:TO select 330 patients with respiratory failure of CPHD from 4 hospitals by retrospective research method,and to collect related data of s TCM syndrome.All data were analyzed by description,logistic regression and clustering analysis.Results:327 qualified questionnaires were collected.The incidence frequency of TCM syndrome of CPHD with respiratory failure was syndrome of heat-phlegm stagnating the lung,syndrome of pulmonary stagnation of phlegm,syndrome of deficiency of the lung and kidney qi,syndrome of deficiency of qi and stagnation of blood,syndrome of edema due to yang deficiency,syndrome of kidney qi deficiency,syndrome of deficiency of both qi and yin.7 TCM syndromes were screened out by cluster analysis.They were syndrome of heat-phlegm stagnating the lung,syndrome of pulmonary stagnation of phlegm,syndrome of deficiency of the lung and kidney qi,syndrome of edema due to yang deficiency,syndrome of obstruction of pericardium by phlegm,syndrome of blood stasis and syndrome of deficiency of both qi and yin.7 were screened out as the main TCM syndromes of the disease,and the main symptoms and the sub-symptoms of the elementary symptom-complexes were screened out by statistical description.Conclusion:There were 7 main TCM syndromes of CPHD with respiratory failure,they were syndrome of heat-phlegm stagnating the lung,syndrome of pulmonary stagnation of phlegm,syndrome of deficiency of the lung and kidney qi,syndrome of obstruction of pericardium by phlegm,syndrome of blood stasis,syndrome of edema due to yang deficiency and syndrome of deficiency of both qi and yin.The results will provide references for next research.
