To explore The clinical study of Metformin combineded with Shenqi Injection in diabetic heart disease,in order to provide theoretical support for clinical treatment.Methods:A total of 80 cases of diabetic heart disease from 2014 March to 2014 September in our hospital were divided into the experimental group and the control group.The control group wast treated by Metformin,while The patients in experimental group were treatmented by Metformin combineded with Shenqi Injection.After the treatment，Clinical curative effect,ECG,Beckoning echocardiography and left ventricular hypertrophy were compared.Results:After the treatment，the clinical curative effect of experiment group was better than the control group(P<0.05),while the blood glucose,left ventricular high voltage and LVH index were significantly better than those before treatment(P<0.05);and all indicators of experiment group are better than the control group(P<0.05).Conclusion:The clinical curative effect of Metformin combined with Shenqi Injection in diabetic heart disease is remarkable,and reduce the blood glucose,while improve heart function of patients，it is worthy of clinical popularization.
