Evaluation of whole left ventricular systolic performance and local myocardial systolic function in patients with prior myocardial infarction using global long-axis myocardial strain.
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.
