Test Description
When your Cardiologist has ordered a Stress MPI test, an IV will be started. A tracer, Technetium or Thallium (not a dye) will be injected. This tracer is radioactive and allows us to image your heart with a special camera. The camera records how blood is distributed to your heart muscle at rest and after stressing your heart; thus you will be scanned twice. Each scan takes about 20-minutes. The entire study takes approximately 2-hours. Stress scans are necessary because coronary artery disease may be detected only after the heart is stressed. You will be stressed one of two ways:
- Exercise Tolerance Test - This is a treadmill test and you will walk at increasingly faster speed on a incline.
- Pharmacologic Stress Test - Adenoscan will be injected while you are on a gurney over a 4-minute period. Adenoscan "mimics" the blood flow normally seen with exercise without walking on a treadmill. Symptoms may include flushing, headache, chest discomfort, shortness of breath, and nausea. This is usually normal and these symptoms typically resolve within a minute after the injection is over.
