What Is Ejection Fraction? Ejection fraction, or EF, is a measurement that indicates how well your heart is functioning. This number tracks how much blood your heart is pumping out with each contraction. Your ejection fraction is described as a percentage. If youâre healthy, your ejection fraction is generally between 55% and 70%. For instance, an ejection fraction of 60% means your heart is pumping 60% of your blood out of your left ventricle (its main pumping chamber) every time your heart beats. What Is Low Ejection Fraction? Low ejection fraction, sometimes called low EF, is the term we use to describe your ejection fraction if it falls below 55%. It means your heart isnât functioning as well as it could. If a diagnostic test indicates that you have low ejection fraction, your doctor will want to thoroughly check you for a heart condition. If you get to a 35% ejection fraction or below, you are at high risk of developing a dangerous arrhythmia and going into heart failure. Low Ejection Fraction Causes. Many different heart and vascular diseases can lead to low ejection fraction, including: 1  Cardiomyopathy: This condition causes areas of heart tissue to thicken. 2  Coronary artery disease: This heart disease narrows or blocks the two main arteries that supply blood to your heart muscle.
