A nuclear stress test, sometimes referred to as a "cardiolite" or "thallium" test, lets doctors see pictures of a patient's heart while he or she is resting and shortly after the patient has exercised. The test can show how well the heart is pumping blood and if the heart has any damaged muscle.
Nuclear stress tests can also give doctors information about the patient's arteries and whether they might be narrowed or blocked because of coronary artery disease (CAD). Radioactive agents, called "tracers," are injected to produce an image of the heart. These agents are widely used and very safe. Although nuclear testing is usually done in conjunction with an exercise stress test on a treadmill, it can also be performed using medication that simulate the effects of exercise on the heart.
