Characteristics of Mitral Annual Movement in Patient with Coronary Heart Disease (CHD) by Doppler Tissue Imaging (DTI)

Objective DTI was used to quantitatively analyze mitral annual movement velocity of CHD patients and to evaluate left ventricular systole and diastole function. Methods 2DE and DTI were performed in 52 CHD patients and 20 subjects without heart disease. DTI including Vs,V E,V A and V E/V A of mitral annual's 6 locations. Results comparied with those of normal people, Vs,V E and V E/V A of mitral annual of CHD patients were reduced and velocity were changed. Conclusion DTI can early reflect the changes of left ventricular function. It also can provide new parameter for evaluating the effect of cardiac disease treatment. [
