A Myoview stress test is used to check for coronary artery disease. During the procedure, a small amount of radioactive isotope called Myoview is injected into a vein, one injection is given through an IV when you first begin the exam called resting images, and a second injection is given while you exercise on a treadmill. The Myoview circulates in your bloodstream and is absorbed by your heart while a special camera takes pictures that show whether your heart is receiving enough blood and oxygen.

During the Procedure
A temporary IV will be inserted into your arm at the start of the test to make it easier to introduce the Myoview into your vein. During the exercise stress portion of the exam, electrodes will be attached to your chest so an electrocardiograph machine can monitor your heart rate. The Myoview will be injected while you are exercising at your peak level when indicated. Your blood pressure will also be checked at various points during the procedure. For the resting images, you will also be injected with Myoview and then asked to wait for approximately 30 minutes for the solution to circulate in your bloodstream. For the pictures after the stress test as well as those for the resting studies, you will lie still on a table while a large camera slowly rotates around your chest.
After the Procedure
You may return to your normal routine.
