A nuclear stress test is a diagnostic imaging procedure that uses radioactive material and a special camera to assess blood flow to the heart both at rest and under stress. This test helps in identifying areas of the heart that may not be receiving enough blood.

Preparation typically involves avoiding caffeine and tobacco for 24 hours prior to the test. You might be instructed to fast for several hours before the procedure, and you should inform your provider about any medications you're taking, particularly those affecting heart rate.

During the test, a radioactive tracer is injected into your bloodstream, and images of your heart are captured using a special camera. You will then be asked to perform exercise on a treadmill or a stationary bike, or undergo a pharmacological stress if exercise is not advisable. After stress is induced, additional images are taken to compare blood flow during rest and stress.

Yes, a nuclear stress test is considered safe for most individuals. The amount of radiation exposure is minimal and comparable to that of a standard X-ray. However, your provider will discuss any potential risks based on your personal medical history.

Following the procedure, you will be observed for a short time to ensure your vital signs remain stable. You may resume normal activities once you're cleared by your provider. Any side effects from the radioactive material are generally mild and temporary.

Results from a nuclear stress test are typically available within a few days. Your provider will review the findings with you and discuss any necessary follow-up actions based on the results.
