What is a Myocardial Perfusion Scan?

This scan is used to look at the blood flow to your heart.

How do I prepare for a Myocardial Perfusion Scan?

This scan requires you to be caffeine free for 24hrs before your scan date (NO coffee, tea, chocolate, Milo, Energy drinks or any drink of food containing caffeine, even decaffeinated drinks). You will also need to be fasted from midnight the night before your appointment. Water is allowed and is encouraged at any time before and during your test. If you are taking a medication called Asasantin, please let our reception staff know as soon as possible as you need to cease this medication 2 days prior to your appointment. If you are a diabetic on insulin injections, our reception staff will give you further instruction in preparation for this test. Our reception staff will also advise you on other medications if necessary.

What happens during a Myocardial Perfusion Scan?

During this test, we will be looking at the heart at rest and at stress with pictures taken of the heart before and after stress. The stress test is done in one of 2 ways depending on what your doctor has asked for:

1. We can inject a medication called Persantin over 4 minutes (a chemical that exercises the heart). We will give you another medication to stop any side effects you may experience at the end of this part.

2.  We can exercise your heart by asking you to walk on a treadmill machine.
During this component, our doctor will be with you at all times and will be checking your blood pressure as well as your ECG (heart rhythm and beats) during the test.

Are there any side effects of a Myocardial Perfusion Scan?

The side effects and risks of the stress test will be discussed with you in detail before we start. A written sheet can be downloaded here.

The test is done in several parts and can take up to 5 hours.
