Assessment of Longitudinal Strain in Acute ST – Elevation Myocardial Infarction
Journal Title: INTERNATIONAL JOURNAL OF SCIENTIFIC STUDY - Year 2017, Vol 5, Issue 3
Abstract
Introduction: Strain imaging measures tissue deformation rather than tissue velocity. It localizes regional wall motion abnormalities as does the conventional methods such as WMSI and Simpson method. Conventional methods are based on the principle of measuring tissue velocity. Results: Peak systolic longitudinal strain was reduced in the individual ischemic myocardial segments and uniformly normal in the non-ischemic segments. In anterior wall MI patients the WMSI was increased and strain reduced in mid, apical septum: LV apex: basal mid and apical lateral: basal mid and apical anterior segments statistical analysis of the data revealed positive correlation (>0.50) between the value obtained by WMSI and strain in the basal, mid and apical lateral segments basal mid and apical anterior. Even though the –mid septal apical septal and apical segments showed reduced strain statistical positive correlation was lacking in these areas. Similarly the basal septal, mid apical lateral segments: basal mid, apical inferior segments showed reduced strain and increased WMSI. However only the basal septum, basal, mid, and apical inferior segments showed positive correlation (>0.5). Correlation between 2D Simpson derived EF and strain derived EF was also calculated. The correlation was strongly positive in the AWMI group with a value of 0.87. The correlation in the IWMI group was also positive at 0.59. Conclusion: Objective measurement of deformation (strain), in patients with acute myocardial infarction detected myocardial regions involved as well as the overall left ventricular (LV) function. These measurements, the WMSI and strain correlated with each other with regards to the regional as well as global LV function. Analysis based on coefficient of correlation showed peak systolic longitudinal strain as good as WMSI in this prediction
