Radionuclide Angiography, Resting and Exercise

What to Expect

What to Do the Night Before
You should not eat for at least four hours before the test. If you take medications in the morning, ask your physician about taking them before the test. If your physician wants you to take your medications, you may use a small amount of water to help you swallow them.

If you smoke, you may be asked to not smoke for a period of several hours before the procedure. The nicotine in cigarette smoke may cause spasm in the coronary arteries, which could affect the test results.

Diagnostic Tests Before the Procedure
None.
