Objective:

2

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:

2

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:

2

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:

2

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.
