Objective: To understand the relationship between the coronary Angiography (CA) reflected degree of coronary artery lesion and the TCM Syndrome Differentiation-type (TCM-SDT).
Methods: Patients TCM-SDT were differentiated adopting the standard of Syndrome Differentiation for coronary artery diseases revised in 1990, and the comparison of TCM-SDT with the findings in CA was carried out.
Results: CA examination showed that 29 patients (39.73%) were of one-artery lesion, 9 patients (12.33%) two-artery lesion and 35 patients (47.95%) three-artery lesion; the stenosis degree of them were: 54 arteries were mild stenosis, 38 moderate stenosis and 31 severe stenosis; 29 arteries were completely occluded, the sum total of affected artery was 152 (69.41%), and the other 67 arteries (30.59%) had no lesion. TCM-SDT showed that all the 73 patients had secondary Excess Syndrome, among them 73 patients (100%) with blood stasis Syndrome, 39 patients (53.4%) with Phlegm-Turbid Syndrome, 16 (21.0%) with Qi-stagnation Syndrome and 7 (9.6%) with Cold condensation Syndrome. 63 patients (86.3%) with obvious primary Deficiency Syndrome, among them, 57 (78.1%) were Qi-Deficiency, 18 (24.7%) Yang-Deficiency, 28 (38.4%) Yin-Deficiency and 5 (6.8%) Yang collapse. All patients had blood stasis of various degrees, manifesting on tongue proper prominently. In the 80.8% patients who had angina pectoris, 74.0% had their mouth, lips and gum dark red, dark purple or light dark in color. The comparison between TCM-SDT and Blood-Stasis score revealed that patients of Cold condensation-blood stasis Syndrome and Yang collapse-blood stasis Syndrome were serious. Patients of Qi stagnation-blood stasis Syndrome and Yin Deficiency-blood stasis Syndrome were mild cases, while patients of Phlegm Turbid-blood stasis Syndrome and Qi Deficiency-blood stasis Syndrome were moderate severity cases. The number of affected artery in Cold condensation patients was the most, and in Yin-Deficiency patients was the least. The coronary artery stenosis degree in patients of Qi-stagnation and Yin-Deficiency were milder than in those of Yang-collapse and Yang-Deficiency patients.
Conclusion: The more the number of arterial lesion, the severer the degree of stenosis and the higher the blood stasis score, then the more serious the degree of stasis.
