Ejection Fraction and Why It’s Important

If you’ve been diagnosed with congestive heart failure, you may have heard your heart doctor discussing ejection fraction (EF). EF is a measurement that lets your heart doctor know how much blood your heart is pumping out of the left ventricle each time it contracts. Normally, a person without heart conditions will have an EF of about 55 to 70 percent. This means that 55 to 70 percent of the blood is being pushed out with each contraction.

If a person’s EF is under 40, this may be indicative of congestive heart failure or cardiomyopathy. An EF measurement between 40 and 55 could reveal damage to the heart, such as from a previous heart attack. However, it is not necessarily indicative of heart failure. A very high EF may also be cause for concern. An EF greater than 75 percent may indicate hypertrophic cardiomyopathy. However, since it is possible to have a normal EF and still have heart failure, your ejection fraction is just one of the many aspects of your heart health that your cardiologist will review.
