Left ventricular (LV) global strain along its long axis during systole, which is obtained by dividing mitral annular excursion by the distance from the mitral annulus to the LV apex at end-diastole, can be used to assess whole LV systolic performance. The evaluation of LV wall function using this parameter suggests that previous myocardial infarction (MI) causes long-axis myocardial function in remote normal LV walls, as well as in walls with MI, to deteriorate.
左心室（LV）在收缩期沿其长轴的整体应变可用于评估左心室整体收缩功能，该应变通过舒张末期二尖瓣环位移除以二尖瓣环至左心室心尖的距离获得。使用该参数评估左心室壁功能表明，既往心肌梗死（MI）会导致梗死周边正常左心室壁以及梗死壁的长轴心肌功能恶化。
