A) The volume of the four flow components by mean percentage ± SD in relation to the end diastolic volume. (P values calculated by ANOVA). B) Kinetic energy (KE) values for each flow component at end diastole. Bars show mean ± SD. The significant statistical differences for the KE values of the direct flow and residual volume components are highlighted between the patient groups and the healthy controls. (P values calculated by ANOVA for parametric data or Kruskal-Wallis for non-parametric data). C) Correlations between the direct flow component kinetic energy at end diastole and the 6 minute walk test, Minnesota heart failure score, LV ejection fraction and LV mid-circumferential systolic strain. (r calculated with Spearman's correlation).
