The AIB and ACVIB of non infarcted myocardium were observed in both groups. The LV diastolic function indexes were determined:early and late diastolic mitral annular velocities(Ea and Aa) and Ea/Aa were measured by using the tissue Doppler imaging;

• 观测两组患者非梗死区心肌的AIB,ACVIB,测定左室舒张功能应用组织多普勒检测二尖瓣环舒张早期和晚期运动速度(earlyandlatediastolicmitralannularvelocities,EaandAa),及两者的比值Ea/Aa;
