What Does Ejection Fraction Have to Do With Heart Failure?

Ejection fraction is a measure of how well the heart is pumping blood. It is expressed as a percentage and is calculated by dividing the volume of blood pumped out of the heart by the total volume of blood in the heart.

A normal ejection fraction is between 55% and 70%. When the ejection fraction is below 40%, it is considered to be heart failure.

Heart failure occurs when the heart is unable to pump enough blood to meet the body's needs. This can be caused by a variety of factors, including:

* Coronary artery disease

* High blood pressure

* Diabetes

* Obesity

* Smoking

* Alcohol abuse

* Drug abuse

Heart failure is a serious condition, but it can be managed with medication, lifestyle changes, and, in some cases, surgery.

Ejection fraction is an important measure of heart function, and it can help to diagnose and manage heart failure. If you have a low ejection fraction, it is important to talk to your doctor about your treatment options.
