What it is

Ejection fraction is a pump-function measure commonly reported from heart imaging, especially echocardiography.[2,1]

Why it matters

Heart failure can happen when the heart cannot pump enough blood, and heart tests can assess how well the heart pumps.[1,2]

What it affects

  • EF belongs with symptoms, volume status, valve function, chamber size, rhythm, BNP, and clinical history.[1,2]

Interpretation traps

  • BioConst does not interpret a personal EF value or classify heart failure subtype.[1]
