Myocardial Perfusion Imaging

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.

 

Warning:  This test is not recommended for pregnant women.

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 can measure the heart's capacity to work, and help diagnose cardiac abnormalities that may not be present while at rest or during normal activities.  This test 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 treadmill 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.

During the second part of the test, you will exercise on a treadmill starting at very slow speed, gradually increasing the speed and incline.  A physician or nurse practitioner will be present during the stress 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.  Your heart rate and blood pressure will change with the increased level of activity. When your heart rate reaches a predetermined rate, the technician will again inject the tracer; you will continue to exercise for one more minute.  After waiting approximately 45 minutes to allow the tracer to circulate and absorb into the heart, you will have a second heart scan, which will take about 20 minutes.

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.
