What does 30% heart function mean?

Moderately below normal (30% to 40%): Patients experience heart failure with reduced left ventricular function symptoms. “The heart can’t supply the demands of the body because it can’t eject enough blood on every beat, so it increases in size and rate to compensate,” Dr.

What is the lowest percentage your heart can function at?

The left ventricle is the heart’s main pumping chamber. It pumps oxygen-rich blood up into your body’s main artery (aorta) to the rest of the body. A normal ejection fraction is about 50% to 75%, according to the American Heart Association. A borderline ejection fraction can range between 41% and 50%.

How long can you live with weak heart?

Although there have been recent improvements in congestive heart failure treatment, researchers say the prognosis for people with the disease is still bleak, with about 50% having an average life expectancy of less than five years. For those with advanced forms of heart failure, nearly 90% die within one year.

What happens when your heart is only working at 40 percent?

An ejection fraction below 40 percent means your heart isn’t pumping enough blood and may be failing. A low ejection fraction number can be an indicator of heart failure and may not have symptoms at first but can lead to a variety of symptoms, including: Shortness of breath. Fatigue.

Can a heart function at 30 percent?

Normal EF is in the range of 55% to 70%. As the percentage falls, it tells the doctor that the heart failure is getting worse. In general, if the EF falls below 30%, it’s relatively severe. A reading of 20% or below is very severe heart failure.

What does 40 percent heart function mean?

40 to 55% – Below normal heart function. Can indicate previous heart damage from heart attack or cardiomyopathy. Higher than 75% – Can indicate a heart condition like hypertrophic cardiomyopathy, a common cause of sudden cardiac arrest. Less than 40% – May confirm the diagnosis of heart failure.

What is the average lifespan of a person with congestive heart failure?

The life expectancy for congestive heart failure depends on the cause of heart failure, its severity, and other underlying medical conditions. In general, about half of all people diagnosed with congestive heart failure will survive five years. About 30% will survive for 10 years.
