Cardiomyopathy and ejection fraction

Does a higher than 75% ejection fraction always mean cardiomyopathy?  It says my echo is normal and all measurements looked good so does that mean I am in the clear.  I am just reading every on the internet that higher measures could mean cardiomyopathy  mine was 79%

That is not a significant variant could just be a little hyperdynamic from excitement or nervousness. If you had anything else your doc would have told you I assume.

You are dealing with a fraction, right? Volume remaining in the LV after contraction/total volume in the LV before contraction. The denominator should always be the largest value.

First of all the EF is too high unless Smo2928 is an extremely superior athlete..So there are two things that can affect one's EF to make it abnormally higher.

1)  Anything that INCREASES the remaining volume in the LV after contraction i.e. the left ventricle is not emptying like it should. (aortic valve obstructing discharge, mitral valve leaking into the LV chamber, or other things of this nature)

2) Anything that DECREASES  the total volume in the LV before contraction i.e. the LV is not filling like it should. (mitral valve dysfunction or obstruction within the pulmonary vein, possible aortic valve leaking, the hole or opening between the LV and RV at birth that heals quickly by a "flap" of skin within the heart. This hole is where the umbibical chord from the mother attaches to the unborn child. I forgot the name of the condition where this flap of skin does not "seal" off.  The condition is called PFO and I will post some info I stole below. ( I love tabbed browsing, lol.)

Smo2928, I would not worry at all about this EF. As Tickertock said it may just have been kind of a freak thing. If I had any symptoms, I would scream out the fact that I had a measured EF of 79. Good luck,

Jack

*PFO stands for patent foramen ovale, a hole in the wall that divides the right and left chambers of the heart. We all have a PFO during before birth, but it usually closes before birth. The right side of the heart receives blood and pumps it to the lungs for oxygenation. The blood then goes through the left side of the heart to be pumped to the brain and other organs. A PFO can allow blood that hasn't been oxygenated to get into the left side of the heart and pumped to the brain and other organs. If this happens, the body doesn't get enough oxygen. It's also possible that blood clots can pass through the PFO and cause a stroke. PFO is diagnosed with a TEE (transesophageal echocardiogram), which is performed by passing an ultrasound probe down the esophagus, near the heart to get better results than the traditional echocardiogram, performed with a standard ultrasound wand outside the chest.

I do have mitral valve prolapse with mild regurgitation could that cause it?
