Diagnostic Tests
Cardiac Nuclear Stress
A Cardiac Nuclear Stress test helps your physician evaluate how your heart works “at rest” as well as when it is “stressed” via controlled treadmill exercise or with a drug that mimics the body’s response to exercise. It will enable your doctor to determine if your heart is getting enough blood supply from your coronary arteries.
During the procedure, small electrodes are placed on your chest and connected to an EKG machine. An IV is placed in your arm for the injection of radiotracers. A special camera measures the tracer signals while you are “at rest” and “stressed.” Computerized images are created.
This test takes 3-4 hours. A physician monitors and supervises the stress test. Your results will be read by certified cardiologists.
To prepare for your exam:
- Wear comfortable clothing.
- Do not eat or smoke for four hours before the test.
- You may bathe the day of your study. DO NOT apply any powder or lotion to your chest area.
- Ask your physician if you should make any changes in your medication, as certain drugs must be stopped 24 hours before the exam.
- Do not consume any drugs, food or beverages containing caffeine 24 hours before the exam. For a list of drugs, food or beverages containing caffeine, please click here.
