What is a Nuclear Heart Test?
A Nuclear Heart Test, also known as a nuclear stress test or myocardial perfusion imaging, is a non-invasive procedure used to evaluate the blood flow to the heart. It involves injecting a small amount of radioactive tracer into the patient's bloodstream and taking images of the heart at rest and during exercise using a special camera.
Generally, patients prepare for a Nuclear Heart Test by avoiding caffeine and certain medications that may interfere with the results. During the test, the patient is connected to an electrocardiogram (ECG) machine to monitor their heart rate and blood pressure. They will then walk on a treadmill or pedal an exercise bike while the healthcare provider injects the tracer into their bloodstream.
The entire procedure takes about four hours, including the resting images and exercise portion. After the test, patients are usually advised to drink plenty of fluids to help flush out the radioactive tracer from their bodies.
Healthcare professionals perform this examination to assess for coronary artery disease, heart valve problems, and other cardiac conditions. It is often ordered for patients with chest pain, shortness of breath, or abnormal heart rhythms. The test can also be used to monitor the effectiveness of treatments for existing heart conditions.
The results are recorded in a Nuclear Heart Test Report, which includes details of the patient's medical history, medications, and any relevant lab results. The report also provides a visual representation of the images taken during the procedure and an interpretation of these findings by a cardiologist.
