What does a low ejection fraction indicate?
What does a low ejection fraction indicate?
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.
Is low normal ejection fraction bad?
If you have an EF of less than 35%, you have a greater risk of life-threatening irregular heartbeats that can cause sudden cardiac arrest/death. If your EF is below 35%, your doctor may talk to you about treatment with an implantable cardioverter defibrillator (ICD) or cardiac resynchronization therapy (CRT).
Can you have low ejection fraction without heart failure?
Most times, EF refers to the amount of blood being pumped out of the left ventricle each time it contracts. The left ventricle is the heart’s main pumping chamber. Your EF is expressed as a percentage. An EF that is below normal can be a sign of heart failure.
How common is low ejection fraction?
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 can cause ejection fraction to drop?
Decreased ejection fraction doesn’t have many preventable causes. However, it can be triggered by a heart attack, coronary artery disease, diabetes and/or uncontrolled high blood pressure, which can be caused or worsened by: Alcohol or drug abuse. An unhealthy diet, high in saturated fat, sugar and salt.
How accurate is echocardiogram for ejection fraction?
Echocardiography accurately detected LVEF <40% in 27 of these 36 (75%) studies. When compared to angiographic LVEF <40%, echocardiography was falsely low in 19 studies. Echocardiographic studies overestimated angiographic LVEF <40% in 9 studies.
What is normal ejection fraction for a 60 year old?
An ejection fraction of 50 percent to 65 percent is considered normal.
