Figure 3. Prolonged VO2 recovery delay is associated with impaired hemodynamic response to exercise.

Figure 3

A) Cardiac output augmentation during exercise for the controls, HFpEF, and HFrEF groups is depicted as median with IQR. HFpEF and HFrEF groups are stratified by the median HF VO2RD (25s). (* indicates p=0.0015 between HFpEF < 25s and HFpEF ≥25s and ** indicates p=0.003 between HFrEF < 25s and HFrEF ≥25s. A scatter plot of cardiac output augmentation during exercise versus VO2RD for B) HFpEF and C) HFrEF. Spearman rank correlation is included.
