Relationship between LVEF and myocardial strain. Scattergrams for each of the Lagrangian strains plotted against LVEF. Cases are classified according to presence (blue circles) or absence (red circles) of mid-wall fibrosis (MWF). The lines correspond to the 95 % confidence intervals for strain. The top scattergram demonstrates that above an LVEF of 25 % (dashed reference line) MWF alters the relationship between Ɛcc and LVEF: patients with MWF have lower Ɛcc than those with similar LVEF but without MWF
