Background : Ischemic heart disease (IHD) may cause local movement disorders and the assessment of EF systolic function measured by M-mode ultrasound may be wrong. The study aims to provide the value of using tissue Doppler imaging (TDI) to assess the systolic function through the movement of the mitral ring. Subjects and Method: 94 patients with heart failure due to coronary artery disease and 34 healthy people as control group included in this study. We made echocardiography and Doppler tissue of mitral ring at the 2 and 4 chamber views. Results: The S wave of annular mitral valve at 2 and 4 chamber views in patients group were lower than controls: 4.93 ± 1.51cm/s vs 7.50 ± 0.86 cm/s; 4.71 ± 1.66 cm/s vs 7.41 ± 0.84 cm/s, 4.46 ± 0.92 cm/s vs 97.24 ± 0.68 cm/s; 4.66 ± 1.13 cm/s vs 7.70 ± 0.74 cm/s . On the other hand, no difference in the speed of movement according to the artery lesions. Conclusions: The S wave velocity of 4 annular mitral sites decreased in patients with heart failure due to ischemic heart disease. There was no difference in S wave velocity at the 4 sites of mitral annulus according to LAD or RCA lesions. The S wave velocity on the pulse TDI may be used alternatively to assess the systolic left ventricular function.
