An ejection fraction (EF) of 24 percent is considered low. This may indicate heart failure with reduced ejection fraction (HFrEF) or cardiomyopathy, which is an enlarged, thick, or stiff heart muscle. A lower EF means that the heart’s pumping action is weaker, putting the person at higher risk of life-threatening complications, such as cardiac arrest. It is important to discuss this with a healthcare provider to develop a treatment plan.
