Objective:For guiding Clinical Application,the research was designed to evaluate the efficiency and safety of GuanXinDanShen Capsules And Enhanced External Counterpulsation Combination therapy,in the treatment of CHD SAP with the identification of blood stagnates in collateral of heart.Methods:Sixty CHD SAP patients which belong to the identification of blood stagnates in collateral of heart were enrolled and divided into two groups, according to the random trial method.Based on the common western medicine treatment,the patients of therapeutic group(30 cases) were given GuanXinDanShen Capsules and EECP Combination therapy,and the patients of control group(30 cases) were given GuanXinDanShen Capsules.After four weeks treament course,we observed the curative effects of angina pectoris,syndromes of Traditional Chinese Medicine(TCM),ECG,VAS and SAQ scores,Hemorrheology,etc.Results:A total of 60 patients constituted our study sample.Baseline data of the therapeutic group and the control group were comparable(P>0.05).1、The improvement of angina pectoris symptoms:At the end-point,the symptoms of angina pectoris were significantly improved,and angina pectoris scores reduced,in both of two groups(P0.05). 4、The decrease of nitroglycerin consumption:After treatment course,the nitroglycerin consumption was significantly decreased,in both of two groups(P0.05).In the control group,the value of nb(200/s) andηb(3/s) were significantly decreased(P0.05).In the therapeutic group, the efficient of nb(200/s)、HRV、LRV andηp were superior to the control group at the end-point(P0.05) in the remaining two hemorrheology indicators.8、Safety:There was no significant difference about safty between two groups.And there were no serious adverse reactions at the end-point.The treatments are safe.Conclusion:GuanXinDanShen Capsules And EECP Combination therapy is exactly effective and safe for the treatment on CHD SAP patients with the identification of blood stagnates in collateral of heart.It can improve angina pectoris symptoms,TCM symptoms and the quality of life,reduce the amount of nitroglycerin,and improve the hemorrheology indicators.It could be served as a good clinical joint approach.
