Strain in segments with scar transmurality > 50%. Boxplot of segmental circumferential strain (top row) and radial strain (lower row) assessed using three techniques in ten healthy subjects (160 segments) and patients with no signs of pathology in terms of left ventricular (LV) wall mass index, systolic blood pressure (SBP), diastolic blood pressure (DBP), wall motion, late gadolinium enhancement (LGE) and a history of myocardial infarction, (“Non pathology”, 304 segments) and segments with LGE in excess of 50% wall thickness (LGE > 50%, 84 segments). The box plots show median, the two central quartiles in the box, one quartile in each whisker and outliers. Student’s t-test showed significant differences between the two patient groups for all three techniques.***p < 0.001. Healthy subjects depicted for comparison
