What is a Nuclear Stress Test?
- A Nuclear Stress Test provides information about your heart’s ability to deal with an increased need for blood and oxygen which occurs during exercise.
- During a Nuclear Stress Test, an Electrocardiogram (ECG) records your heart’s electrical activity while you exercise on a treadmill, if you are able, or during the infusion of a stress agent.
Why Am I Having This Exam?
This test is performed for many reasons including:
- To diagnose disease of the arteries in the heart
- To help diagnose the cause of chest pain
- To determine the level of the heart’s physical condition
- To assess the degree of recovery after Coronary Bypass surgery or PTCA/Stent (Angioplasty)
- To determine how well the heart is recovering after a heart attack
- To identify the causes of irregular heart rhythms
What Should I Expect During My Test?
- You will be asked to complete paperwork and answer questions regarding your health history.
- The Nuclear Medicine Technologist will explain the exam. A small IV will be placed in your arm or hand so that a small amount of Myoview (a radioactive tracer) can be injected. The radioactive dose gives you less radiation exposure than what you would receive from a Chest X-Ray. Myoview is not a "dye" or "contrast" and it is not iodine based. Therefore, you will not have side effects or reactions from Myoview.
- Pictures will be taken of your heart at rest after a 30 minute wait. These pictures take about 20 minutes.
- For the Stress Test, electrodes will be placed on your chest. Your heart’s electrical activity will be recorded. Sometimes, hair needs to be shaved from the chest to ensure good contact with the skin.
- A blood pressure cuff will allow monitoring before, during, and after your Stress Test.
- If a pharmacological agent is used to stress the heart, some side effects may occur. All aspects of the test will be explained thoroughly before the exam begins.
During the stress portion of the exam, another small amount of Myoview will be injected through the IV.
- The last set of images will be taken approximately 30 minutes post-stress injection and will again take approximately 20 minutes.
