A nuclear stress test measures blood flow to your heart, both at rest and during stress stages on the heart. It’s performed similarly to a routine exercise on the treadmill, but provides images through Nuclear Medicine Imaging that can show areas of low blood flow in the heart and any areas of damaged heart muscle.
A nuclear stress test is used to show your physician how well your heart works during physical activity versus how well it works at rest. The test usually involves taking two sets of images of your heart — one set while you’re at rest or laying on a table and another set while you’re exercising on a treadmill or stationary bike with medication that stresses your heart.
