Sestamibi Exercise Test. This test is used to evaluate the blood flow to your heart at rest and under stress. It will help the doctor determine if the arteries around your heart are narrowed and if the flow of blood to your heart is reduced.

The Preparation

Please do not eat or drink anything with caffeine for at least four hours before the test. Do not smoke before the test. You will be asked to sign a consent form. Please feel free to ask any questions you might have. Wear comfortable shoes and clothes.

The Procedure

An intravenous (IV) is started when you arrive. Sestamibi (Cardiolite) is a radioactive material that is given through the IV site. It acts to image the heart muscle when lying under the special gamma camera after the exercise test.

You will be asked to walk on a treadmill or ride a stationary bike. Your heart rate, blood pressure, and electrocardiogram will be monitored during the procedure. At any time during the test, if you experience chest pressure, dizziness, or any other complaint, please let the physician know.

After the exercise portion, you will be asked to eat/drink something fatty. This helps empty the gall bladder of any sestamibi. This will enhance your heart pictures.

After an hour’s wait, you will be asked to lie down on a table under a camera. The imaging takes approximately 45 minutes.

Your IV will be removed before you go home. Your doctor will have the results of this test by the next day. If you have any questions or concerns, please ask your doctor.
