Analysis of Chinese syndrome features and combination laws of 2029 patients with coronary heart disease angina

Objective: To explore the element distribution features and syndrome combination laws of coronary heart disease angina.

Methods: The syndrome database of 2 029 patients with coronary heart disease angina was established to study the syndrome elements and syndrome combination laws.

Results: (1) The syndrome element distribution of coronary heart disease angina was featured as: blood stasis > qi deficiency > phlegm turbid > yin deficiency > phlegm turbid with more warm property > yang deficiency > stagnant qi > phlegm turbid with more cold > cold coagulation. Of them, qi deficiency and blood stasis were the main two syndrome elements, and phlegm turbid with more warm and yin deficiency also occupied important positions. (2) Syndrome combination laws of coronary heart disease angina: three elements syndrome and two elements syndrome were dominant. The combination of sthenia syndrome element and asthenia syndrome element was the most important combination laws. Qi deficiency and blood stasis was the main combination form.

Conclusions: Qi deficiency, yin deficiency, phlegm turbid, and blood stasis form four key links of its pathogenesis, in which, qi deficiency and blood stasis was the most basic pathogenesis. The syndrome element combination had some laws.
