What is a nuclear stress test (NST)? A nuclear stress test uses an imaging machine and radioactive dye to create detailed pictures showing the blood flow into and out of your heart both while at rest and during exertion.
A nuclear stress test is done if your doctor wants to guide treatment of a heart disorder or check for a heart disorder. A nuclear can also help you and your doctor to understand how well your heart is pumping, if your heart is too large, and your risk for heart disease or complications.
How should I prepare for the test?
You may be asked not to eat, drink or smoke before the nuclear stress test. For an NST, you may also be asked not to have any caffeine before the test. Please avoid caffeine. This includes avoiding decaffeinated tea, coffee, soda, chocolate, and certain pain relievers. Be sure to wear comfortable shoes and clothes for the test.
The test will take about 3 to 6 hours, with a break inbetween.
If you have an inhaler, please bring it to the test and inform your doctor or technician that you use an inhaler.
Medications: inform your doctor about all medications you are taking, you may be asked to discontinue a certain medication before the test. Do not discontinue any medication without consulting your doctor first.
