Fig. 4

Case examples of KE curves in control and two MI patients with preserved LVEF and reduced LVEF. First panel: The total KE of the LV is reduced in MI patients. The minimal KE demonstrates an increase in MI patient with reduced LVEF. Second panel: Diastolic KE curves at different levels of the LV (base, mid-ventricular and apex). The diastolic KE curves demonstrate blunting of peak E-wave KE in the two patient groups. Time differences to peak E-wave KE propagation increase in each group (orange arrows between the two dotted black lines). EF = ejection fraction, nEF = normal ejection fraction, pEF = preserved ejection fraction, KE = kinetic energy, LV = left ventricle and MI = myocardial infarction
