What Is The Sestamibi Stress Test
See below: A sestamibi stress test is used to detect decreases in blood to the heart muscle during exercise or chemical "stress." such decreases in flow may indicate partial or complete blockage of one or more of the coronary aeries that supply blood to the heart muscle. ...Read moreSee 1 more doctor answer
Stress affects most people in some way. Acute (sudden, short-term) stress leads to rapid changes throughout the body. Almost all body systems (the heart and blood vessels, immune system, lungs, digestive system, sensory organs, and brain) gear up to meet perceived danger. These stress responses could prove beneficial in a critical, life-or-death situation. Over time, however, repeated stressful situations put a strain on the body that may contribute to physical and psychological problems. Chronic (long-term) stress can have real health consequences and should be addressed like any other health concern. Fortunately, research is showing that lifestyle changes and stress-reduction techniques can help people learn ...Read more
MPS: I believe you are referring to a myocardial perfusion scan, where technitium sestamibi 99 is the radioactive isotope that is injected intravenously so that images can can be taken of the heart at rest and 'stressed' or exercrsing -which brings us to the adenosine: a pharmacological agent used to 'stress' the heart instead of walking on a treadmill. Lexiscan is the stress agent of choice now. ...Read moreSee 1 more doctor answer
See below.: This is a chemical stress test of blood flow to the heart muscle. It is used to evaluate patients who are unable to exercise. Pictures of blood flow are obtained before and after the stress. Post stress abnormalities may indicate narrowings of the coronary arteries which impede blood flow and may be a cause of chest pain. Abnormalities of flow before stress may indicate previous damage. ...Read moreSee 1 more doctor answer
Nuclear study: This is a nuclear medicine test that tells your physician about your heart function. A small amount of nuclear tracer is given right after/during running on a treadmill followed by a scan. This is compared to a similar scan performed at a separate time under resting conditions. Any decreased area of tracer uptake in the heart during stress compared to rest indicates a possible artery block. ...Read moreSee 1 more doctor answer
See below: A stress thallium test uses a nuclear tracer to visualize blood flow during exercise or chemical stress in a person unable to exercise. The purpose of the test is to uncover artery narrowings that can impede flow when an increased demand for flow is required as in"stress." the test can also give information about the heart's pumping power called the ejection fraction. ...Read moreSee 1 more doctor answer
Checks heart functio: Thallium is a radioactive (minimally) isotope that is used to study the pumping capability of the heart, usually after heart attack or prior to surgery in someone with cardiac disease. Sometimes it's done simply to ensure proper cardiac capability in someone with risk factors or prior heart issues. It involves mild to increasing exercise to "stress" the heart and assess function under effort! ...Read more
None: Thallium provides no risk to any human as it is non-toxic and is eliminated from the body within a few hours after the test is completed. It is simply a tracer chemical for blood flow. ...Read more
Nuclear stress test: The patient walks on a treadmill or other exercise device or has a medication injected to simulate exercise, when the exercise or medicine is in progress a radioactive agent is injected which goes into the heart and can be imaged to show the blood flow into the heart muscle. The information shows if enough blood gets into the heart muscle and other information. ...Read more
Thallium: Thallium poisoning is extemely rare. Radioactive thallium used in the test is thallium 201 and is used in a small dose that dissipates with about a 69 to 73 hr halftime. The radiation is generally no problem unless it is additive in a person who has had lot of radiation exposure. ...Read more
Cardiac stress test: There are various drugs we use during cardiac stress testing with imaging. For routine treadmill or bicycle exercise stress testing without imaging, no drugs are used. When we do perfusion imaging we use thallium 201 or sestamibi for the imaging. We do use adenosine and other agents to facilitate the myocardial perfusion imaging especially if exercise isn't done. ...Read more
Depends: It depends what your doctor is looking for. Ultrasound, cardiac ct and MRI may be able to show how strong your heart is beating (ejection fraction) and if there is any wall motion abnormalities. Cardiac ct and MRI can even look at the vessels, which nuclear scans cannot. However, nuclear cardiac scans are considered the standard of care for looking at how well the blood perfuses the heart tissue. ...Read moreSee 1 more doctor answer
Not generally: Some people are concerned that stressing a heart that does have coronary artery disease can cause heart attack. Fortunately never seems to be the case. Can get arrythmia from some meds, but complications also quite rare. Usually benefit far outweighs risk. ...Read moreSee 1 more doctor answer
Stress test : This is a chemical stress test. You will be given a medication and then pet scan of your heart will be done to evaluate the blood flow in different parts of the heart. If there is any significant blockage, it will show up as a defect in the images. ...Read moreSee 2 more doctor answers
CAD: The purpose is to diagnose significant coronary artery disease (CAD). If the scan is positive for ischemic changes in the heart, then you will benefit from aggressive medical treatment, angiographic treatment, or surgery. If the scan is negative (and done properly), your risk for CAD or a significant injury such as a heart attack in the next few years is very low. ...Read moreSee 1 more doctor answer
Heart Disease Test: Thallium stress test is a nuclear imaging method that shows how well blood flows into the heart muscle, both at rest and during activity. Normal blood flow would "light up" on images. The stress portion is either through exercise, like on a treadmill, or a drug can be injected for those who can't tolerate regular exercise. This causes the heart to behave as if the subject were exercising. ...Read moreSee 1 more doctor answer
A stress test is a cardiac test which can include walking on a treadmill and monitoring your heart while you are walking. They can also inject you with a nuclear material and do a more comprehensive scan on your heart to check for blockage. They can also do a chemical stress test which omits the need to ...Read more
