This test will take about 3 - 4 hours in the office.
- An IV will be started in your arm. A dose of a very safe radiopharmaceutical (Myoview) is injected. This travels through the body and concentrates in your heart. There are no side effects, and it does not change how your heart functions. The nuclear camera does not go over your head but pivots over the chest to take images of the heart. Next, to exercise your heart for the stress test, one of 2 methods will be used.
- Nuclear Treadmill Study: You will be asked to walk on a treadmill until your heart reaches an 85% maximum predicted heart rate (calculation based on age). Your doctor may attend this part of the test. Once your heart rate has increased, the imaging isotope will be injected through the IV. Pictures will be taken a second time of your heart.
- Pharmacological Study: Lexiscan will be given through your IV for 10 seconds. You may or may not experience shortness of breath, chest discomfort, headache, nausea, and/or a warm flushed feeling. If experienced, these symptoms subside shortly after stopping the medication. Pictures will be taken a second time of your heart.
- 15-120 minutes after the Stress Test, “stress images” will be taken while your heart rhythm is monitored. This completes the exam.
