Relationship Between Myocardial Oxygen Consumption and Myocardial Blood Flow, Hemoglobin and Group (Myocardial Oxygen Extraction)

HFpEF vs Control
Model R2 = 0.77 Parameter Est (SE)* p value
MBF, per 10 ml/min 1.4 (0.1) <0.0001
Hgb, per g/dL 3.6 (1.0) 0.0007
Group, HFpEF vs Control 5.7 (2.6) 0.03

Determinates of MVO2 (ml/min) across the range of resting and stress values in HFpEF and Controls. Data reflect multivariable least squares regression analysis. Abbreviations: MBF, Myocardial Blood Flow; MVO2, myocardial oxygen consumption; HFpEF, heart failure with preserved ejection fraction and Hgb, hemoglobin.

*

The change in MVO2 per unit of MBF, Hgb or Group.
