[The occurrence of cardiovascular events of coronary heart disease inpatients and study on Chinese medicine syndrome distribution laws].

OBJECTIVE: To explore the correlation between Chinese medicine (CM) syndrome elements and follow-up cardiovascular events in coronary heart disease (CHD) inpatients, thus providing the clinical evidence for CM syndrome typing. METHODS: Adopting prospective design and method of principal component and Logistic regression analysis, we studied the distribution laws of CM syndrome elements in 1 005 CHD inpatients according to the follow-up cardiovascular events. RESULTS: The dominant CM syndrome elements in CHD patients were blood stasis, qi deficiency, turbid phlegm, and yin deficiency. After 1-year follow-up, 66 CHD patients suffered from acute cardiovascular events. The analysis results demonstrated that the second principal component composed of qi deficiency and yin deficiency with statistical significance in Logistic regression (P = 0.036). CONCLUSIONS: Blood stasis, qi deficiency, turbid phlegm, and yin deficiency were main syndrome elements of CHD inpatients. Qi deficiency and yin deficiency might be relevant CM syndrome elements of the CHD inpatients who suffered from acute cardiovascular events in the 1-year follow-up.
