What Is The Persantine Sestamibi Stress Test
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
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
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
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
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
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
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
