A Nuclear Stress Test is ordered to evaluate and/or diagnose heart disease, also sometimes performed after a failed Regular Stress Test
The nuclear stress test can be performed with a treadmill and without a treadmill, (chemical stress test)
During the process of evaluating a safe level of radioactive substance if given through an IV.
This radioactive dye will be taken up by the healthy cells of the heart. The effects of the substance will only last for 2 – 5 minutes.
Pictures of your heart will be taken when you first arrive and after your heart has been stressed, either with a treadmill or chemically.
If the heart is healthy, both the pictures before and after the treadmill or chemical test will be normal.
Our Cardiologist will review these pictures, noting the blood flow at rest and after stress, a decrease in blood flow would be evidence of a blockage in one or more of your arteries.
The Nuclear Stress test can help rule out coronary heart disease and determine the severity of it.
This is a safe test and can be used in place of other tests, such as a coronary angiogram, which carries a higher risk of complications.
The nuclear stress test can take up to 2 hours for completion.
