What Is the Significance of an Abnormal Ejection Fraction?


Quick Answer

While a high ejection fraction is good, an abnormal one could be an indication of certain heart conditions, including hypertrophic cardiomypathy. Typically, a normal ejection fraction ranges from 55 to 75 percent, as stated by CPMC. The ejection fraction of an individual is usually expressed as a percentage.

An ejection fraction helps to determine the pumping of the heart with each beat. It is measured through a test referred to as echocardiogram. In this test, an imaging machine uses sound waves to create an image of the heart. There are also other tests that can be used in measuring ejection fraction, including nuclear medicine scans, magnetic resonance imaging, cardiac catheterization and computed tomography. The ejection fraction of a person can go up or down depending on his heart condition, as stated by Cleveland Clinic.

It is important for a patient to know his ejection fraction, which is necessary in understanding his heart condition. A person who has recorded a low ejection fraction is usually at risk of suffering from heart failure. Luckily, there are ways that a patient can raise his ejection fraction. These include limiting salt intake, exercising regularly and managing fluids, as stated by Heart Rhythm Society.
