Average left ventricular strain as calculated by a semi-automatic prototype software calculating Lagrangian strain from deformation field analysis with 95% CI. A - mean peak radial strain value amongst the 3 groups; B - mean of average segmental peak radial strain value amongst the 3 groups; C - mean peak circumferential strain value amongst the 3 groups; D - mean of average segmental peak circumferential strain value amongst the 3 groups. * indicated statistically significant (p < 0.05) difference from volunteer group.
