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 45 percent heart function?

A low ejection fraction (or low EF) is typically 45 or less and can be evidence of heart failure or cardiomyopathy (a disease of the heart muscle). The heart’s ejection fraction (EF) refers to the amount – or percentage – of blood pumped (or ejected) out of the heart’s left ventricle with each contraction.

Is an ejection fraction of 60 good?

Generally, a normal range for ejection fraction is between 55% and 70%. Low ejection fraction, sometimes called low EF, is when your ejection fraction falls below 55%. It means your heart isn’t functioning as well as it should. Your doctor will want to thoroughly check you for a heart condition to find the cause.

Is 52 ejection fraction good?

A normal ejection fraction range is between 52 and 72 percent for men and between 54 and 74 percent for women. An ejection fraction that’s higher or lower may be a sign of heart failure or an underlying heart condition.

What is 50 percent heart function?

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%.

What is normal ejection fraction on echocardiogram?

The ejection fraction is usually measured only in the left ventricle. 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.

How accurate is an echocardiogram?

How Accurate Is An Echocardiogram Stress Test? Health / By Ivan In comparison with exercise ECG (especially in women and patients with left ventricular hypertrophy), stress echocardiography can detect significant coronary stenoses at a rate of 80–90%.

What does an echocardiogram tell you?

Look for heart disease

  • Monitor heart valve disease over time
  • See how well medical or surgical treatments are working
  • What to expect during an echocardiogram?

    You lie on a table and a technician places small metal disks (electrodes) on your chest.

  • The room is dark so your technician can better see the video monitor.
  • Your technician puts gel on your chest to help sound waves pass through your skin.
  • Your technician may ask you to move or hold your breath briefly to get better pictures.
  • What are normal echocardiogram results?

    CW,Continuous wave Doppler; PR,pulmonic regurgitation; PW,pulsed wave Doppler; RA,right atrium; RF,regurgitant fraction; RV,right ventricle.

  • ∗ Unless there are other reasons for RV enlargement.
  • ∗∗ Exception: acute PR
  • § At a Nyquist limit of 50-60 cm/s.
  • φ Cut-off values for regurgitant volume and fraction are not well validated.
