I am online and happy to help you with your question today.
A 37% loss of cardiac function is considered significant. If by low, you mean is it crippling? That depends on many factors.
There are patients who have significantly more loss of cardiac function and are still alive....
What they are usually talking about with this number is XXXXX ejection fraction -- the amount of blood that is squirted out of your heart with every beat.
When talking about ejection fraction, not heart muscle function, normal is anywhere from 55 to 70%. If this is the measurement you were given then that is considered normal. I'm sorry about the earlier confusion....I did not know what parameter you were referring to.
That is high BP and defiantly should be treated.
The low values at night, however, are going to make managed of your HTN tricky.....
Low BP at night can cause damage to your optic nerve, brain, kidney's and other organs.
My pleasure. Have a Happy New Year.
