Heart Rate, Stroke Volume, and C(a-V)O2 Association With Peak VO2

Characteristics HFpEF
HFrEF
Controls
Partial R2 P Value Partial R 2 P Value Partial R 2 P Value
HR max 0.350 <0.0001 0.307 <0.0001 0.342 0.006
SV max 0.072 0.077 0.379 <0.0001 0.436 0.001
C(a-v)O2 max 0.281   0.0002 0.253   0.0001 0.187 0.056

HR, SV, and C(a-v)O2 are adjusted for age and sex both and VO2 is indexed to body weight. HFpEF indicates heart failure with preserved ejection fraction; HFrEF, heart failure with reduced ejection fraction; HR, heart rate; and SV, stroke volume.
