Nuclear Stress Test Myocardial Perfusion Scan

Nuclear Stress copy
A nuclear stress test which can also be called a myocardial perfusion scan can cause a little anxiety.
Just the hearing about a nuclear stress test sounds like a war. Negative things go through our head. Well this test provides some valuable information about your heart in terms of coronary artery disease risk or progression.

A Nuclear Stress test or Myocardial Prefusion Scan is something to take very seriously. Doctors will prescribe a nuclear stress test but if you are having any investigation about your heart it is a good reason to ask why.

Sometimes we just take doctors word for getting a test done which may be fine but you should always ask why. A nuclear stress test is a type of myocardial imaging (mycardial perfusion scan). The reason it is called a nuclear stress test is because it uses a radioactive isotope called a Thallium, MIBI or cardiolite so this test is often called a
Thallium Stress Test
MIBI Stress Test
Cardiolite Stress Test

It is provides your healthcare team with valuable data on how your heart is functioning. But you should read this FREE special report on “Heart Testing and Nuclear Stress Test” to determine if this test is for you.  You are exposed to a lot of radiation along with inserting a radioactive dye that can stay with you for weeks.

What happens in a Nuclear Stress Test or Myocardial Perfusion Scan?


A nuclear stress test or myocardial perfusion scan is a diagnostic test to determine blood flow the heart muscle. You basically perform an exercise stress test at which at the end you are injected with a nuclear radioisotope die. This die then distributes into your heart at which they will take radiation images of your heart and see how the radioactive die distributes around your heart. They will take images right after you exercise then again when you are resting (usually a few hours later). If you are unable to exercise they may inject a pharmacological agent to increase your heart rate to distribute the dye.


They are looking at how the radioisotope die distributes around the heart. If the die does not reach an area of the heart then they consider that to be ischemic (lack of oxygen or blood flow to the heart). They can determine which arteries are not doing what they are supposed to.


Nuclear Stress Test or Myocardial Perfusion Scan-  Is the Dye Safe?

The chances of something bad happening while you are performing these tests are relatively low. Obviously you will be in a lab and they are able to handle emergencies if the situation were to arise. The nuclear stress test or myocardial perfusion scan dye used is considered safe, but do you really want to be “radioactive” for a few weeks. Yes a few weeks. This is where it warrants a good conversation with your doctors to see if the test is necessary. In our free report we will discuss some key things to look out for to see if you require these tests and understand everything you have to know from a patient perspective.
IF you have been prescribed to get a nuclear stress test or myocardial perfusion scan  then it is important to start to look at your heart health. Heart disease is preventable and even reversible. Please get our special report to understand The Truth behind Heart tests: Nuclear Stress Test.
