Nuclear Exercise Stress Test

What a nuclear exercise stress test is

Sometimes, the arteries that supply blood to the heart muscle can become clogged or narrowed from the buildup of plaque. This is called atherosclerosis or coronary artery disease. A nuclear exercise stress test evaluates blood flow to your heart muscle — during periods of exercise (stress) and rest — to help doctors determine if you have a blockage in one or more arteries of the heart.

For this procedure, we use safe, radioactive tracers that are injected into your blood through an IV (intravenous) line — via a vein in your arm — to examine your blood flow. Images of the tracers allow us to see the heart muscle receiving the blood supply more clearly.
