To explore the standard of syndromes of coronary heart disease(CHD) angina pectoris and conduct a quantitative diagnosis on qi deficiency of heart. Methods: This study collected twenty years of papers discussing coronary heart disease associated with angina, and the information of 3090 cases of TCM syndrome. Using frequency, sorting, logistic stepwise regression method to determine the most common syndrome of angina pectoris of coronary heart disease: heart qi deficiency, blood stasis, phlegm stagnate syndrome, qi and yin deficiency, yang deficiency, cold stagnation and yin deficiency. Yin deficiency is actually rare to be seen. Single factor analysis and logistic stepwise regression method was further used to select the relevant factors. Conditional probability conversion method was used to mark the related factors. Applying maximum likelihood discriminant method to determine the threshold of quantitative diagnosis. Besides, to do retrospectively test of standard quantitative diagnosis of deficiency syndrome of heart qi deficiency, the establishment of the coronary heart disease and angina pectoris. Their sensitivity, specificity, accuracy, positive predictive value, and negative predictive value were calculated respectively. Results: The quantitative diagnosis related factors Chinese Medicine syndrome of heart qi deficiency was: chest tightness, heart and chest pain, shortness of breath, lassitude, spontaneous perspiration, burnout lazy words, pale tongue, thin white fur, and fine pause. The score was 2-13. The diagnostic threshold of qi deficiency syndrome of qi was 28. According to the retrospective test, sensitivity, specificity, accuracy, positive predictive value, and negative predictive value were 71.25%, 87.14%, 83.37%, 63.32%, 90.68% respectively. Conclusion: Based on the frequency of symptoms, it is feasible to establish a quantitative criteria of TCM syndrome in patients with coronary heart disease.
