Pharmacologic Myocardial Perfusion

This test is a three-part test involving a stress test and scans of the heart to determine if your heart muscle is receiving adequate blood supply at rest and with activity. It is a special type of stress test for people that cannot exercise on a treadmill.

 

Warning:  This test is not recommended for pregnant women.

This test is a three-part test involving a stress test (no exercise) and scans of the heart to determine if your heart muscle is receiving adequate blood supply at rest and with activity.  It is a special type of stress test for people that cannot exercise on a treadmill.  Instead, a medication that dilates your coronary arteries and increases blood flow to your heart is used to simulate what happens when you exercise.  This test can help diagnose cardiac abnormalities that may not be present while at rest or during normal activities.  It may be done as part of a diagnostic work-up for suspected heart disease, or following recovery from a heart attack or heart surgery. 

Preparation

If your stress test is in the morning, you may have a light breakfast.  If it is scheduled in the afternoon, you may have a light lunch.  If you are having other tests that require special preparation, adjust these instructions accordingly.

24 Hours Prior

  • Do not drink or eat any caffeine (coffee, tea, cola or chocolate.)
  • No alcohol,
  • No smoking.
  • Do not take any caffeine-containing medications (Anacin, Excedrin, No-Doz, Darvon, etc.)
  • Wear loose fitting shorts or slacks and a pair of lightweight, flat-heeled shoes, preferably tennis shoes.
  • Check with your ordering doctor about taking any medications before the test.
  • Do not apply any lotion or powder to your chest, as they may prevent the EKG electrodes from staying in place.  It may be necessary for the technician to shave small areas on your chest where the electrodes will be applied.

Procedure

A technician will first place an IV needle into your arm and give the first injection of the nuclear imaging tracer.  You will sit and relax for 30-60 minutes while the tracer is circulating in the bloodstream and being absorbed by the heart muscle.  Next you will be positioned on the scanning table and a camera that rotates around your chest will take pictures of the heart; this takes about 25 minutes.  You will then be allowed to leave, but you will need to return for the stress portion of the test.  Do not smoke or drink coffee or other beverages with caffeine as they will interfere with the stress portion of the test.

During the second part of the test, EKG leads and a blood pressure cuff will be applied to monitor your heart rhythm, pulse rate and blood pressure before, during and after the “exercise.” You may sit, lie down or walk slowly on the treadmill during the test.  The medication will be infused through the IV needle over approximately four minutes.  This medication may or may not cause mild nausea, dizziness, headache or flushing for a short time; these effects usually resolve a couple of minutes after the infusion is completed. Your heart rate and blood pressure will change during the infusion.  When the infusion is done, the technician will again inject the tracer, and you will have a second scan of the heart which will take approximately 20 minutes.  A physician or nurse practitioner will be present during the “stress” portion of the study.

Results

A cardiologist will interpret the stress test.  The results will be reviewed by the ordering physician who will contact you with your results.  


NOTE:  Testing times above are approximate.  It is estimated the test will take two to three hours to complete.
