Abstract： Objective： To observe the clinical effect of Yinxingye Tablets combined with western medicine for stable angina pectoris(SAP) and its effect on heart function and hemorheology. Methods： A total of 390 cases of SAP patients were divided into the control group and the observation group according to the random number table method， with 195 cases in each group. The control group was treated with routine western medicine，and the observation group was additionally treated with Yinxingye Tablets based on the treatment of the control group. Both groups were treated for six weeks. Traditional Chinese medicine syndrome scores，heart function indexes and hemorheology indexes before and after treatment as well as the clinical effects and the frequency and duration of angina attacks were compared between the two groups. Results：After treatment，the scores of chest pain，palpitations and lack of strength in two groups were decreased， the difference being statistically significant(P＜0.05)， and the above scores in the observation group were lower than those in the control group，the difference being statistically significant (P＜0.05). After treatment， the frequency of angina attacks in the two groups were decreased and the duration of angina pectoris were shortened， the difference being statistically significant(P＜0.05)； the frequency of angina attacks in the observation group was less than that in the control group(P＜0.05)，and the duration of angina pectoris was shorter than that in the control group(P＜0.05). After treatment，the left ventricular end systolic diameter(LVESD) and left ventricular end diastolic diameter(LVEDD) in the two groups were decreased(P＜0.05)， and the left ventricular ejection fraction(LVEF) was increased(P＜0.05)； LVESD and LVEDD in the observation group were lower when compared with those in the control group， and the LVEF was higher than that in the control group(P＜0.05). After treatment，whole blood high shear viscosity， plasma viscosity， erythrocyte sedimentation rate， hematocrit and fibrinogen levels in both groups were decreased(P＜0.05)，and the levels of the above five hemorheology indexes in the observation group were lower than those in the control group，the difference being statistically significant(P＜0.05). The effective rate was 89.74% in the observation group，higher than that of 78.46% in the control group(P＜ 0.05). Conclusion：The therapy of Yinxingye Tablets combined with western medicine for SAP has a good clinical effect，and can improve the clinical symptoms，heart function and hemorheology of patients.
