Myocardial Perfusion Test


At Corrielus Cardiology, we proudly offer a variety of advanced testing methods to evaluate the condition of your heart. A myocardial perfusion test, or nuclear stress test, is used to examine the function of the heart, measure blood flow to the heart and detect heart blockages. We use myocardial perfusion testing to diagnose and monitor a number of cardiac conditions, including coronary artery disease (CAD), hypertrophic cardiomyopathy and abnormalities within the heart walls. Not all patients experience outward symptoms when they have a heart blockage. Therefore, a nuclear stress test can be a life-saving procedure that is performed comfortably in a single clinical visit. When it comes to addressing your heart health, Corrielus Cardiology is committed to offering the most proven non-invasive testing services available. Our integrative cardiovascular services guide patients towards improved heart health and better overall wellness.

What is a Nuclear Stress Test?

A nuclear stress test is an effective diagnostic testing tool that can evaluate blood flow to the heart and determine if there are any areas of blockage. During the test, a small dose of radioactive material (isotope) is administered through an IV. Computer images capture how much of this radioactive material is absorbed by different areas of the heart. A “stress” component of the test can also be added during this procedure, which is typically done by having the patient walk on a treadmill or perform light exercise. This allows Dr. Corrielus to evaluate the amount of blood flow to the heart at rest and during activity. By assessing the amount of highlighted radioactivity that is “taken up” by the heart muscle, we can accurately confirm or eliminate the presence of a blockage in the heart

Rest assured that our cardiac testing methods are safe and painless at Corrielus Cardiology. During a nuclear stress test, the amount of radiation exposure is equivalent to spending a couple of hours in the sun or undergoing a single CT scan. The radiation dissipates in the body within hours after it is administered.
