From parasternal long axis, LVDd and LVDs were measure by M-mode;From apex four chanmber view, EDV and ESV were measure by simplified Simpson method, LVEF was calculated, and by the pulse doppler of mitral and aortic valves, mitral valve diasolic flow E wave, A wave, ICT, IRT,and ET were measured.

AMI患者74例入院后行超声心动图检查，在胸骨旁长轴用M型测量LVDs，LVDd，心尖长轴切面用简化Simpson氏法测量EDV，ESV，并计算LVEF，多谱勒超声心动图采集测量二尖瓣和主动脉瓣血流频谱，测量二尖瓣舒张期血流E峰，A峰，ICT，IRT和ET，按公式计算Tei指教=/ET。

All subjects recieved the test of Two-Dimensional echocardiography and PW-TDI.3.1 LV end-diastolic diameters, RV end-diastolic diameters and inter-ventricular septum and posterior wall thicknesses were measured from the parasternal long-axis projection. LV end-systolic and diastolic volumes,RV end-systolic and diastolic volumes were obtained from the

所有入选者均行常规二维超声和组织多普勒超声心动图检查 3.1 常规二维超声心动图(two-dimensional echocardiography，2D)检查：采用胸骨旁左室长轴切面M型测量左室舒张末期前后径、右室舒张末期前后径、室间隔厚度、左室后壁厚度；心尖四腔、二腔切面面积勾画法分别测量左室、右室舒张末期容量和收缩末期容量并计算左室
