What is a nuclear stress test?
A nuclear stress test combines imaging technology, small amounts of radioactive material, and an exercise stress test to diagnose and monitor heart problems. Your doctor may use a nuclear stress test to diagnose coronary artery disease and assess damage from a heart attack or other heart problems. A nuclear stress test can also show how well your heart pumps blood.
A nuclear stress test, sometimes called a thallium stress test, is an important test because some heart problems can only be seen when the heart is under stress from exercising. A nuclear stress test also provides important information about how the heart is functioning. Other imaging methods, such as X-rays and CTs, do not show how the heart responds to stress.
A nuclear stress test is only one method to monitor and diagnose heart conditions. Discuss all of your testing options with your doctor to understand which options are right for you.
