Frequently asked questions and answers (cardiolilte/persantine stress test)

How long will the Cardiolite remain in my system?

Your body will eliminate the Cardiolite after one or two days.

Why do I have to wait before the scan?

This allows time for the Persantine or Cardiolite to perfuse into your system.

Why do I have to have an IV?

It is easier to inject the Cardiolite while you are walking on the treadmill if it is done through an intravenous. It prevents you from having two separate injections.

How does the Cardiolite work?

The Cardiolite binds itself to the red blood cells and is circulated to the heart. We take pictures to show if there are any occlusions (obstructions) in blood flow to the heart.

Why do I have to exercise with this test?

The exercise stresses the heart so we can see if there are any changes that will indicate areas sensitive to stress.

Why do I have to sign a consent form?

There are slight risks to this test and the consent form allows you to be treated should any problems occur during the test.

Is the Cardiolite a dye?

No, the cardiolite is a radioactive isotope. It is not a dye and does not have any side effects.
