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.
How long can you live with low EF?
Conclusion: Three year survival is low when ejection fraction is very low.
What happens if your ejection fraction is low?
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).
