“What Is A Normal Ejection Fraction Value?” Asks Simone
I just received a question from Simone about her 66-year old father. Her email reads, “Hi Adam - My father was just diagnosed with severe mitral regurgitation. This is a very stressful time. His cardiologist rattled off a bunch of terms and numbers which suggested valve replacement. One of those terms was ejection fraction (I think). What does that mean? What is a normal ejection fraction? Thanks, Simone”
This is a great question. So you know, I didn’t fully understand the ejection fraction until I was in cardiac rehabilitation. When I reviewed my post-op echocardiogram with Debbie, the head nurse at cardiac rehab, she explained it to me.
The ejection fraction is a measurement of the capacity at which your heart is pumping. According to the Mayo Clinic, during each heartbeat cycle, the heart contracts and relaxes. When your heart contracts, it ejects blood from the two pumping chambers (ventricles). When your heart relaxes, the ventricles refill with blood. No matter how forceful the contraction, it doesn’t empty all of the blood out of a ventricle. The term “ejection fraction” refers to the percentage of blood that’s pumped out of a filled ventricle with each heartbeat.
Because the left ventricle is the heart’s main pumping chamber, ejection fraction is usually measured only in the left ventricle (LV). A normal LV ejection fraction is 55 to 70 percent. The ejection fraction may decrease if your heart has been damaged by a heart attack or other problems with the heart valves or muscle.
I hope that helps Simone!
Keep on tickin!

Hi, I had my echo done last fall and the doctor said I had a glob in front of the heart, but not on the heart nor in the sack….he did a CT scan of the chest which did not show anything and then did a CT scan of the heart, which also showed nothing, including no calcification in the heart and the valves looked fine. He also said my heart is pumping at 80+ percent, which he felt was wonderful for a 72 year old female. Has anyone else been told that they have a glob of something in front of the heart, but no one knows what it is? The cardiologist said it was there four years ago and had only gotten a little larger in four years and it did not seem to be pressing on the heart…still a little nerve racking.
