what is normal ejection fraction

A normal ejection fraction is typically considered to be 50% or higher. However, different sources may have slightly different ranges for what is considered normal. According to the Mayo Clinic, a left ventricle ejection fraction of about 50% to 70% is categorized as normal, while a mildly reduced ejection fraction is usually between 41% and 49% . The Cleveland Clinic also provides a range of 52% to 72% for males and 54% to 74% for females as normal ejection fraction percentages. The American Heart Association states that a normal hearts ejection fraction is between 55 and 70 percent. WebMD mentions that many doctors consider a normal ejection fraction to be 55% to 75%, and a percentage of 50% or lower is considered a sign that the heart may not be pumping out enough blood. Therefore, while there may be slight variations in the exact range, a normal ejection fraction is generally considered to be around 50% or higher.
