Figure 3.

Left ventricular ejection fraction in relation to VO₂peak/THV ratio. Left ventricular ejection fraction (LVEF) for A) all subjects and B) control subjects and heart failure patients with LVEF > 50% and C) VO₂peak/THV ratio for the control subjects and heart failure patients with LVEF > 50%. In the heart failure patients with LVEF > 50% there was a significantly lower VO₂peak/THV ratio despite a slightly higher LVEF compared to the control subjects. The solid line represents the mean value. * p < 0.05 and *** p < 0.001
