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. The treatment group added Yiqi Yangyin and Huayu Tongluo Recipe granules.The changes of metabolic equivalent (METs), angina symptoms, TCM symptoms, BNP, hypersensitive C-reactive protein (hs-CRP) ,Interleukin-6 (IL-6), Tumor necrosis factor- (TNF-α) and left ventricular ejection fraction (LVEF) were analyzed after 1 course of treatment and Corrected TIMI Frame Count(CTFC) after six month. 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. Conclusion Yiqi Yangyin and Huatan Tongluo Recipe can effectively alleviate angina pectoris symptoms in patients with coronary heart disease complicated with type 2 diabetes after PCI, suggesting cardiac function,inhibiting inflammatory response, and improving microcirculation disturbance.
