這是什麼

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

為什麼重要

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

它會影響哪些判斷

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

解讀陷阱

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