As one of the mainly complication of type 2 diabetes (T2DM), diabetic cardiomyopathy(DCM) has become a high risk factor that affect the patient’s prognosis in the future. Whereas because of the asymptomatic cardiac function with preserved ejection fraction in the early stage of the disease, the impairment due to the DCM would be inclinable to be ignored in clinic. Therefore, the on time diagnosis of the cardiac dysfunction in DCM patients is necessary. The sensitive and non-invasive speckle tracking echocardiography (STE) has been demonstrated to be reliable to discover the subclinical cardiac dysfunction in many cardiovascular diseases including T2DM, but the current work was more focused on the systolic cardiac deformation. On the other hand, some evidences showed that in the early stage of this disease, cardiac diastolic deformation also existed. Therefore, the more entire analysis of deformation data in patients both in systole and diastole should be considered.
