What does functional capqcity mean on a cardiovascular stress test?

Hi everyone,

I'm sorry if I'm asking my questions in the wrong place.

I had a cardiovascular stress test done, and I called my doctor's office for my results. I didn't speak to my doctor directly. The person who took my call said my doctor ordered this time a nuclear stress test with medicine without the treadmill, and they said the cardiovascular stress with treadmill was functional capacity, and the person I spoke with said she doesn't know what functional capacity means. I am asking on here to see what does functional capacity means? Does it mean I'm fine? Or does it mean there are problems? If it means I'm fine then why is there a need for a nuclear stress test with medicine?

Could someone please write back and help me understand?

Thank you,

The normal treadmill test is not 100% accurate.

With a Nuclear Stress Test they inject you with an isotope and take pictures of your heart after exercise and at rest, these pictures give a good indication of weather your heart is getting a good blood supply - they'll probably be looking for blocked arteries.

The only 100% way of knowing if you have blocked arteries is by having an Angiogram (Cardiac Cath).

Good luck.

The doctor tries to measure your functional capacity, or how much stress your cardiovascular system can be put under.

When you had the test, did the doctor stop it early, or did the doctor challenge you with faster and more inclined testing? Did you get wiped out, or suffer from more significant symptoms before the test was supposed to be over?

It depends upon how well you did on the test. If the test had to be stopped early, or if you suffered from increased symptoms, it might mean that you have some CAD.

I would guess, and it's only a non-professional guess, the doctor observed that your functional capacity was less than acceptable according to the ekg, your blood pressure, your heart rate, your fatigue, etc, during the test and he wants a more definitive test.

It could also mean that your doctor is trying to increase his revenues by sending you for more testing, whether warranted or not. It could also mean that your doctor did not do too good in medical school.

Best of luck and health to you!

Re: What does functional capqcity mean on a cardiovascular stress test?

I found out the reason why he ordered a Nuclear stress test with medicine because I went to see my doctor today.

Its not because of my health that I couldn't perform well with the treadmill, but because its difficult since I am MR. Anyway, the reason is they did increase the speeds, but I couldn't perform well so that makes the results invalid. Since I wasn't able to perform well with doing execersize on a treadmill to get my heart beating faster, so with a Nuclear stress test they would be using a chemical to get my heart beating faster.

I was all worried for nothing, but the results was invalid because I wasn't on the treadmill long enough.

I hope that helps.

Why was the stress test ordered in the first place?
