By Mayo Clinic Staff. A nuclear stress test measures blood flow to your heart at rest and while your heart is working harder as a result of exertion or medication. The test provides images that can show areas of low blood flow through the heart and damaged heart muscle.
A nuclear stress test is similar to the exercise stress test or pharmacological (chemical) stress test, but a small amount of radioactive substance is used to determine the health of the heart and blood flow to the heart.fter the test, the doctor will discuss the results with the patient. The nuclear stress test may show: 1  Normal blood flow during rest and exercise-this means heart function appears to be normal at all times. 2  The patient probably does not have coronary artery disease. 3  In most cases, no further tests are required.
