Your physician has ordered either a Lexiscan or Adenosine Nuclear Stress Test. The purpose of this test is to evaluate the blood supply to the heart muscle. We hope the following information will help you to prepare for the test. WHAT WILL HAPPEN DURING THE TEST?
On the day of your test, an IV will be started in your arm. You will receive a dose of a radioisotope through your IV and, after waiting for about 30-45 minutes, you will have a Nuclear Medicine scan. After your scan, you will be taken to the stress lab, electrodes will be placed on your chest to record an electrocardiogram (ECG), and a blood pressure cuff will be placed on your arm to monitor your blood pressure. You will be given a medication that dilates the arteries in your heart, increasing the blood flow. If you are able to, you will walk slowly on the treadmill. The medication is infused through your IV for four minutes. During this infusion, you will receive another injection of radioisotope. Your ECG and blood pressure will be monitored throughout the test. You will have a second Nuclear Medicine scan a short time after your stress test is completed. The test takes approximately 2 ½ to 3 hrs to complete. Your physician’s office will call you within a few days with your test results. HOW SHOULD YOU PREPARE?

It is absolutely necessary to avoid all caffeinated items for the entire day prior to
the test. These include coffee and tea (including decaf), caffeinated sodas,

chocolate, cocoa, and certain pain medications that contain caffeine, such as
Excedrin, Anacin, Midol, Fiorinal, etc. Please read the label. If you have any
additional questions about caffeine, please call.
