EF of 90%

[jobecky]

I have an EF of 90% and I am not an athlete by any means. I have a pacemaker and had 2 stent placements about 4 months ago. One doctor told me a had narrowing between the 2 stents and wanted another stress test. I am only 43 years old.


This discussion is related to what is a normal ejection fraction/LVH.

I agree with is_something_wrong,  Sympthetic and parasympthetic nerves with CNS will increase and decrease contractility as well as increase or decrease the heart rate, and that condition can be the result of stress, etc.  Also the EF is a snapshot of the cardiovascular system at the time of the test  and is not a static parameter and that includes other compensating factors, heart rate and blood pressure, etc.

I don't see a connection with vessel stenosis and EF. Do you have chest pains?

Thanks for chosing this forum for your questions. Take care,

I think EF should be seen in combination with diastolic function (how well the heart is able to relax and fill) and similar important; total cardiac output.

Did your doctor mention thickened heart walls (hypertrophy)? A heart with enlarged walls is often able to contract well (strong muscle) but often not able to relax, which means the amount of blood pumped is still low, and an enlarged heart requires more oxygen (like a bodybuilder) so this may cause angina signs (relative angina).

Just speculating here. There is a possibility you were extremely nervous during the test, which may increase EF. Ask your doctor what he thinks the reason is.
