An LVEF over 75% is considered too high, and medically-termed as being a hyperdynamic or a hypercontractile left ventricle , that is, the heart is pumping forcefully/forcibly, an excessive amount of blood is being pumped out.
According to various medical literature, there a few specific clinically-recognized causes of a hyperdynamic/hypercontractile left ventricle, which includes aortic valve regurgitation (leakage),sometimes the mitral valve, some congenital heart defects (e.g., septal defect), and hypertrophic cardiomyopathy (HCM). The condition may/can also be deemed as idiopathic (no known cause).
Did the doctor or report mention LV hyperdynamic systolic contractility? ...usually if there was any underlying issue to cause that, they would mention it in the report......it can cause symptoms depending on the underlying cause. It can also be a normal variant in young individuals and athletes. Ask your cardiologist for some explanation for the forceful contractility of your left ventricle.
I have moderate MVR, and that does limit my exercise tolerance due to shortness of breath.
Before you push for disability, get reports from good cardiologists. In the forces they may try to make your condition appear less problemtatic to keep costs down.
I thought an EF of 77% was a little high for someone of 36yrs old. I thought the regurgitation had the possibility of causing me problems later. I will be separating from the Air Force in several months and will need to see doctors to determine if I'll be eligible for disability. I think I'll need a stress test. Should I be happy if they award me a 0% or should I push for higher. Regardless, hopefully they'll refer me to a good cardiologist that will provide me with a thorough diagnosis.
Basically the volume of blood in a ventricle is calculated when the heart is relaxed. Then the volume of blood remaining in the ventricle after it has 'squeezed' is calculated. This then allows us to determine the volume of blood that has been pumped out of the chamber. We can work out a percentage of the total blood ejected from the heart from these numbers and that is your ejection factor.
The volume in a ventricle chamber when it is relaxed(before squeezing) is the end diastolic volume EDV.
The volume in a ventricle after contraction is the end systolic volume ESV.
The difference between the two is obviously how much blood volume has been pushed out of the heart, the Stroke volume (SV).
Ejection Fraction is the SV divided by the EDV.
E.G. A man has 70ml stroke volume (SV) - blood pushed out of chamber
end diastolic volume 120ml (EDV) - blood in relaxed chamber (full)
70ml/120ml = 0.58 = 58% EF
LVEF - left ventricle RVEF - right ventricle
Normal values are - 50/55 - 75%
Anything above 75% is classed as abnormal and can be a result from heart tissue damage or inefficient Mitral valve. Above 75% the blood is too forceful when leaving the heart and can cause high blood pressure. There have been people with LVEF of 90%
and above.
I hope this helps you.
