Essential Things You Should Be Aware of When It Comes to Nuclear Stress Tests
A nuclear stress test is a stress test for the heart that uses low dosage radioactive chemicals. The test is designed to produce an image of the blood flowing to your heart muscles.
Doctors perform such tests on patients because they wish to discover whether blood flow has been diminished. Reduced blood flow means that there is a blockage in the system somewhere, possibly in the heart itself. Patients can either exercise or be at rest when a nuclear test is performed. Since exercise causes stress to the body, the heart and the complete cardiovascular system, the test is referred to as a stress test.
One version of the nuclear stress test relies on the use of a radioactive compound referred to as Thallium. Since very small quantities of the substance are used, there is no danger to the body. Thallium becomes less radioactive over time and it is also removed naturally from the body quite speedily.
However, Thallium is the compound that permits doctors to recreate an accurate image of the size of your heart’s chambers. That gives doctors a good idea about the state of your heart as well as other information. In addition, doctors will gain insights into the ability of the heart to pump blood. Based on these images, doctors can also tell if the heart is suffering from any damage. Doctors may feel that a stress test is necessary in many situations. Doctors do not want to run the risk that they’ve overlooked anything. Most doctors find that this test will either confirm suspicions of heart disease or eliminate it as an option. The most common situations when this test is ordered is when other indicators or symptoms of heart disease are present. Then, yet another situation is when a patient has greater than normal risk factors associated with heart disease. Some people are better off taking regular stress tests – especially if they are displaying symptoms that could be any number of possible conditions.
Regular cardiac tests use EKGs (electrocardiograms). This device leaves a little room for interpretation. Sometimes, changes in the EKG can be caused by things that are not at all related to heart disease. For this reason, when there are anomalies in the results of an EKG rest period doctors will need to make a decision about the testing situation. For this most part this involved ordering a stress test of a different type. The average participant will find that the typical stress test remains a viable option. Every kind of cardiac stress test has pros and goal. They assist in helping doctors make the most accurate diagnosis available. Do not forget that there are desired conditions of each test that will or could have an effect on how accurate the results and diagnosis can be.
