2. Example of a typical Δoxygen consumption/Δwork rate (ΔVO2/ΔWR) flattening vs nonflattening patients; from top to bottom, ΔVO2/ΔWR (only exercise), O2 pulse/time (exercise and recovery), and heart rate (HR)/time (only exercise) graphs.

3. Percentage of patients with Δoxygen consumption/Δwork rate flattening (in red, group A) according to the distribution of different underlying diseases.
Percentage of patients with Δoxygen consumption/Δwork rate flattening (in red, group A) according to the distribution of different underlying diseases. HCM indicates hypertrophic cardiomyopathy; HFpEF, heart failure with preserved ejection fraction; HFrEF, heart failure with reduced ejection fraction; HRpHR, high risk patients with hypertrophic remodeling; and MR/TR, mitral regurgitation or tricuspid regurgitation.
