Figure 2.

Distribution of patients with (green dots) and without (red squares) echocardiographic response relative to their exercise performance at baseline. Responders, defined as ≥15% decrease in LVESV, are characterised by faster baseline oxygen VO₂ during onset (A) and recovery (B) of exercise. By contrast, no significant association were observed when evaluating VO₂ peak (C) or VE/VCO₂ slope (D). LVESV, left ventricular end-systolic-volume; VE/VCO₂, minute ventilation for carbon dioxide elimination; VO₂, oxygen uptake.
