目的：探讨行气活血法和益气活血法对冠心病心血瘀阻证的治疗，为临床辩证用药提供依据。方法：从冠心病患者中随机抽取气滞心血瘀阻证30例和气虚心血瘀阻证30例，再将它们随机分配到行气活血法组和益气活血法组中治疗，检测治疗前后的症状、体征、血小板聚集率、血液流变学及心钠素的变化。结果：行气活血法和益气活血法都可以改善患者血小板动能亢进、血液的浓、沾、凝、聚状态，而益气活血法还可增强心功能、减轻心房的压力和扩张程度，而且发现2种治法对证治疗时，效果最佳。结论：辩证论治能发挥治疗的最大效应。

Effect of Qi-benefiting, Qi-promoting and Blood-activating Therapies on Coronary Heart Disease with Blood-stasis Syndrome

Objective: To study the therapeutic mechanism of qi - promoting with blood activating ( QP - BA) therapies for coronary heart disease with blood - stasis syndrome, and provide the evidence for clinical syndrome differentiation and treatment. Methods:30 cases with qi - stagnation and blood - stasis and 30 cases with qi - deficiency and blood - stasis were randomly treated by QP -BA and QB - BA therapies, and the symptoms, signs, platelet agglutination rate, blood rheology and atrial natriuretic factor were observed before and after treatment. Results: Both therapies can alleviate the hyperfunction of platelets and the concentration, viscocity, coagulation and aggregation of blood, but the QB - BA therapy can also enhance the cardiac function and reduce the pressure and dilatation of atrium. The best effect is obtained when the treatment is in accordance with the syndrome differentiation. Conclusion: Treatment according to differentiation may get the greatest efficacy.
