Cardiolite StressTest

Cardiolite Stress Test Patient Information

What is a Cardiolite Stress Test?

A cardiolite Stress Test uses radioisotope (Cardiolite) and exercises (Stress) to assess the amount of blood reaching your heart muscle. A special camera takes images of your heart after the injection of the Cardiolite and again after a period of exercise. It can identify blocked coronary arteries or areas of heart muscle lacking adequate blood supply. It may be used to evaluate the effectiveness of coronary bypass or angioplasty.

Where will the Stress Test be done?

The test will start in the Physical Therapy Department at North Valley Health Center. The scan of your heart will be performed by the DMS Mobile Imaging Service. The equipment is transported to our facility by a special truck. You will be escorted out to the truck in the North Valley Health Center parking lot by a technologist.

When is the Stress Test service provided?

Stress Tests are performed every other Wednesday.

How is the test performed?

You will register in the Physical Therapy Department at NVHC, where you will receive additional information about the test and answers to any questions you may have.

An IV will be started in your hand or arm and Cardiolite will be injected through the IV. After waiting approximately 45-60 minutes you will be taken out to the mobile unit where resting images of your heart will be taken. This imaging usually takes twenty to thirty minutes.

After these images are complete, you will return to the Physical Therapy Department. The exercise (or Stress) test will then begin. You will walk on a treadmill at a brisk pace for a period of time as your heart is monitored. If you are unable to exercise on a treadmill, you may receive Lexiscan (a medication that creates an effect on the heart similar to exercise). A physician is always present during this test.

Following the stress test, your heart rate will be monitored for six minutes during the recovery period. After waiting approximately 45-60 minutes, images will be taken in the mobile unit. After these images are done the test is complete. The IV will then be removed.

When will I get my results?

Your films and report will be read by a Radiologist, who will give your doctor their impression of the test. The nurse will call you to set up an appointment for you to go over the test results with your doctor.
