المستخلص Background: As an index of myocardial infarct size (IS), left ventricular (LV) function is a key determinant of the prognosis after an acute myocardial infarction (STEMI). Traditionally, LV function is assessed by the volume-fraction expelled during systole, i.e. ejection fraction (LVEF), or alternatively by semiquantitative visual grading of LV wall dynamics, i.e. wall motion score index (WMSI). Both methods are subject to observer- and expert-dependence; so in search of a less observer-dependent method, two-dimensional deformation imaging by speckle tracking has been proposed. Aim: Assessment of the global longitudinal peak systolic strain (GLPSS ) by speckle tracking echocardiography in patients with STEMI in first 24hrs after primary PCI and its correlation with LV infarction size and ejection fraction |
