Nuclear stress tests involve the use of low dosage radioactive chemicals in heart stress tests. The goal of the test is to create an image of blood as it flows to your heart.
These tests are conducted by doctors in order to determine whether or not there is any reduction in blood flow. If blood flow is diminished, this alerts them that there is a possible blockage somewhere, even in the heart itself. When a nuclear test is given, the patient can be either exercising or at rest. The reason it is called a stress test is because the exercise puts stress on the body including the heart and overall cardiovascular system.
One variety of nuclear stress test uses Thallium, which is a radioactive compound. Since very small quantities of the substance are used, there is no danger to the body. Also, Thallium will reduce in radioactivity as well as be naturally eliminated from your body in a fairly short time.
Thallium, though, allows doctors to create a representation of your heart’s chambers so doctors can determine their size. A doctor can use these images to determine how healthy your heart is as well as other pertinent data. On top of that, a doctor will be able to determine how easily the heart can pump blood. When doctors see the images of this action, they can also see if there is any heart damage. Doctors may feel that a stress test is necessary in many situations. What you may find is doctor’s want to be very sure they do not overlook anything. With that in mind they order these tests in hopes that they will either eliminate heart disease as a possibility or confirm their suspicions. The most common situations when this test is ordered is when other indicators or symptoms of heart disease are present. These tests are also commonly ordered with patients who exhibit risk factors for heart disease that are above average. Some people are better off taking regular stress tests – especially if they are displaying symptoms that could be any number of possible conditions.
Another kind of common group test is seen as the nuclear stress test. This type of test can be applied with various radioactive isotopes. The purpose of a nuclear stress test is to envision a healthy heart muscle that works properly. The different areas of the heart will absorb the isotope and then become more lit up in an image. The eventual outcome should be to tell which sections of the heart are deprived of blood supplies. This will then provide information about blockages.
As you can see, there are plenty of uses for the cardiac stress test. Your cardiologist is the person who is best trained to determine what may be needed in any particular situation. It is also of the utmost importance to be aware that all tests have limitations and this also refers to the cardiac stress test. For example, plenty depends on achieving the best heart rate. Stress tests with images rely on how good the images are. There are also certain natural conditions and situations that can interfere with image quality, as well.
