Cardiac Stress Test
Check with your doctor to see if you should stop any of your medications a day or two prior to the test.

For 12 hours prior to your test, avoid all foods, beverages and medications that contain caffeine, including:
- Soft drinks—even those labeled decaffeinated or caffeine free
- Aspirin products that contain caffeine, such as Anacin and Excedrin
If you are having a test utilizing Adenosine or Regadenoson, do not take the medication Persantine or Aggrenox (dipyridamole) or any medication that contains Theophylline such as Theo-Dur. You may eat a light breakfast or lunch prior to your test. Avoid strenuous activity on the day of the test. Wear loose and comfortable clothing and comfortable walking shoes. Allow one to three hours for your test, and three hours if you are having a stress test with nuclear imaging.
