It pumps oxygen-rich blood up into your body's main artery (aorta) to the rest of the body. A low ejection fraction is considered to be 35 to 40 percent, or less, of ventricular volume and is indicative of systolic heart failure or congestive heart failure (CHF). Heart failure is an increasingly common condition resulting in high rates of morbidity and mortality. In a healthy heart, the ejection fraction is 50% or higher — meaning that more than half of the blood that fills the ventricle is pumped out with each beat. Get daily exercise and maintain a regular sleep schedule. This number is expected to increase further as people live longer and obesity and diabetes become more common. The benefit was independent of ejection fraction or diabetes status. Remember to pay attention to your body. Healthline Media does not provide medical advice, diagnosis, or treatment.

A quick review of cardiovascular anatomy and physiology helps explain the effects of a low ejection fraction. The amount of blood pumped out to the body is less than normal. A low ejection fraction also results in long-term hypoxia, or low oxygenation, to the all tissues of the body. Severely below normal (less than 30%): Patients with an ejection fraction this low frequently have significant symptoms due to the body’s inability to compensate for it.

Three Year Survival Rate of 20% Ejection Fraction. Even if that chamber pumps the way it should, it doesn’t release as much oxygen-rich blood as your body needs. Left ventricular ejection fraction (LVEF) is the central measure of left ventricular systolic function. These chambers are called the left and right ventricles. An ejection fraction of less than 35% is associated with ABP. A low ejection fraction could also be a sign of a condition such as: Damage from a heart attack; Heart muscle diseases (cardiomyopathy) Researchers say better risk assessment tools should be developed, and more research needs to be done on heart attacks and strokes in South Asians.
