Objective: To evaluate the clinical efficacy of Yiqi Yangyin and Huatan Tongluo Recipe in improving the symptoms of angina pectoris and cardiac function in patients with coronary heart disease complicated with type 2 diabetes after PCI. Methods Sixty-two patients with coronary heart disease complicated with type 2 diabetes after PCI were randomly divided into treatment group and control group, with 31 patients in each group. Both groups were treated with west medicine.

Results The improvement of METS and LVEF in the treatment group was better than that in the control group(P<0.05);the improvement of BNP,hs-CRP,IL-6,TNF-α and CTFC in the treatment group was better than that in the control group;the curative effect of angina pectoris in the treatment group was better than that in the control group; the effective rate of TCM syndrome improvement in the treatment group was better than that in the control group.
