Objective Diabetes mellitus can cause the change of left ventricular structure and function. However, the traditional 2-DE echocardiography can only display the general construction and function of heart with different geometries by detecting the dimension of cavity, the thickness, echo and motion of wall, and can not ascertain the pathological changes of tissues, which can induce the subjectivity in clinical diagnosis. Ultrasonic tissue characterization (UTC) can assess pathological changes of myocardial tissue based on detecting and quantitating the acoustic properties of myocardium. UTC consists of identification and characterization of the abnormalities in the physical or physiological state of biological structures based on analyzing interactions between ultrasound and tissues. Doppler tissue imaging can only display the frequency shift signal of the myocardium and evaluate the myocardial systolic and diastolic function semiquantitatively or quantitatively by myocardial movement velocity based on detecting myocardial wall motion directly. The aim of this study is to determine the feasibility of the use of integrated backscatter and Doppler tissue imaging to assess the degree of myocardial and functional injury in nomaltensive and hypertensive patients with type 2 diabetes.Methods 45 cases of patients with type 2 diabetes in Endocrine Department of the Second Hospital affiliated to DaLian... |
