Objective::To explore the distribution characteristics of traditional Chinese medicine (TCM) syndromes of critical lesions of coronary heart disease, and determine the classification and diagnostic criteria of syndromes, so as to provide reference for the differentiation and treatment of this disease. Method::Totally 1 000 patients with critical lesions of coronary heart disease treated in the Department of Cardiology, Yunnan Provinceal Hospital of TCM from January 2016 to December 2018 were selected as the subjects by clinical epidemiological research methods. Basic information, diagnosis and treatment of the patients, as well as the information obtained through observation, hearing, inquiry and pulse-taking of TCM were collected. Symptoms, signs, tongue signs, pulse signs and other four diagnostic information, as well as relevant clinical data were collected for mathematical statistics analysis by cluster analysis and factor analysis research methods, and expert group opinions were also included in discussion. Result::First, the results of cluster analysis showed six types of basic TCM syndromes in accordance with the clinically actual critical lesions of coronary heart disease: blood stasis syndrome, phlegm turbidity syndrome, cold congealing heart pulse syndrome, Qi deficiency syndrome, heart-kidney Yin deficiency syndrome, Heart-Yang deficiency syndrome. Second, a factor analysis was carried out on the basis of cluster analysis, and the main syndromes of each basic syndromes were preliminarily determined. Third, because of the duplicate content or the unified combination of different syndromes, the TCM syndromes of the critical lesions of coronary heart disease can be summarized in five categories, namely phlegm turbidity and blood stasis syndrome (368 cases, 36.80%), cold congestion heart pulse syndrome (156 cases, 15.60%), Qi deficiency and blood stasis syndrome (315 cases, 31.50%), Yin deficiency of heart and kidney (91 cases, 9.10%) and Heart-Yang depression (70 cases, 7.00%). The main and secondary syndromes refer to factor analysis results of six basic syndromes. Conclusion::Cluster analysis and factor analysis can be made on TCM syndromes of critical lesions of coronary heart disease to pave the way for the classification of TCM syndromes and the establishment of diagnostic criteria of TCM syndromes of coronary heart disease, with an important clinical significance.
