A pump-function measure often discussed in heart failure and cardiomyopathy context.

Views: 16

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]
