FIGURE 7.

Changes in right atrial (RA) active emptying, right ventricular (RV) active filling and backflow after the start of treatment. Patients with high baseline end-diastolic elastance (E_ed) either improved to <0.63 mmHg·mL⁻¹ (green; E_ed responders) or remained high at >0.63 mmHg·mL⁻¹ (red; non-responders). Dots and whiskers represent mean±sem. p-values were determined through pairwise t-test with Bonferroni correction. p-interaction values represent repeated measures ANOVA. a) RA active emptying did not change in either of the groups. b) RV active filling improved significantly in E_ed responders, while there was no change in non-responders. c) Vena cava backflow normalised in E_ed responders, while it did not change in non-responders. BL: baseline; FU: follow-up; ns: nonsignificant.
