Cardiolite Scan - Exercise / Persantine / Dobutamine

When your Family Doctor or Cardiologists wants to assess the blood flow in your arteries they can arrange for a Nuclear Myocardial Perfusion study commonly known as a Cardiolite scan. This test is similar to an Exercise Echocardiogram but instead of using an Echocardiogram we use a nuclear tracer called Cardiolite. We use the Cardiolite to assess your blood flow at rest and then we stress the heart and look at the blood flow again. If there is a blockage in your heart arteries we can see a decrease in blood flow after stress. We stress the heart by one of three methods. The most common is exercise where we have you run on a treadmill. If you cannot exercise we use Persantine which is a medication that opens up your arteries mimicking what happens when you exercise. Typically it does increase your heart rate. You cannot have caffeine for 24 hours prior to a Persantine test. If we cannot use Persantine we can use Dobutamine which makes the heart rate go faster, mimicing the effects of exercise.

This test is done in the Cardiology/Nuclear Medicine Department at the Oakville Trafalgar Memorial Hospital at 327 Reynolds Street in Oakville, Ontario. Please see the link for directions.

Preparations For Testing

Wear running shoes and comfortable exercise clothes. Do not have any caffeine for 24 hours prior to the test. This includes coffee, tea, chocolate, and even some analgesics such as Tylenol with codeine. No alcohol for 24 hours prior to test. You need to fast for 4 hours prior to your test. Since this test uses radiation you should notify the staff if you are planning to travel after your test.
