Myocardial Perfusion Stress Testing (Treadmill, Adenosine, and Dobutamine)

The test consists of two parts, a rest and exercise portion. The entire test will be completed in 3-4 hours. An intravenous (I.V.) line will be placed in your arm or hand vein to allow the ease of the Myoview injection. The I.V. will be removed when the test in completed. Myoview will be administered through the I.V. while you are at rest and once again during peak exercise. After the resting injection of the Myoview is administered you will be asked to wait for one hour to let the tracer circulate. Pictures will then be taken of your heart using a special camera able to trace the Myoview that has localized in your heart. You will be asked to lie down on a special table, the camera will rotate above and around your chest while pictures are being taken, which will take approximately 10 minutes to complete. You may breathe normally while the pictures are being taken. It is very important that you do not move or shift your body while the camera takes the pictures of your heart. You will not receive any radiation from the camera. After the resting images of your heart have been completed, you will be brought to a treadmill room for the exercise stress test. As in a regular stress test, ECG electrodes will be attached to your chest. This will allow the physician or physician's assistant to monitor your heart before, during and after exercise. A blood pressure cuff will be placed on your arm to monitor your blood pressure before, during and after exercise.

The exercise part of the test is usually done with a treadmill, very similar to a treadmill used at a health club. Exercising will begin slowly, and every three minutes the pace and the incline will gradually increase. As you exercise, your heart rate and blood pressure will change. This is normal, and remember, you are being closely monitored throughout the exercise.

At your peak exercise, Myoview will be injected through the I.V. and you will be asked to continue exercising for an additional one or two minutes. Approximately 30 minutes after the exercise is completed, the stress pictures are taken in the same manner as the resting pictures. This will complete the testing. A Cardiologist will interpret the images and a written report will be sent to your primary physician.
