Figure 5.

Peak oxygen uptake in comparison to VO₂peak/THV ratio. Peak oxygen uptake (VO₂peak) for the healthy volunteers and the HF patients (A) which showed a considerable overlap (B). The VO₂peak/THV ratio was, however, significantly lower in the 10 heart failure patients compared to the 10 healthy volunteers with overlapping VO₂peak (C). Dashed lines indicate the overlap between the two groups and the solid lines represents mean values. *** p < 0.001
