Ejection fraction (EF) is one of many measurements of heart function that measures the percentage of blood pumped out of the heart when it contracts. A low EF can indicate heart failure, specifically systolic heart failure. EF is usually measured using echocardiogram, cardiac ultrasound, and other techniques. Normal EF is between 55% to 70%, but a low EF doesn’t always correlate with symptoms. It can also be possible to have a normal EF but still have heart failure due to diastolic heart failure caused by high blood pressure. Whether you should find out your EF depends on your health condition and your doctor’s recommendation, particularly if you’ve been diagnosed with heart failure.
