Thallium Stress Test
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 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 more
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 more
I have undergone cabg n after 2 yrs angiolpasty with 1 stem. Know again after 2 years facing disconfort n advise stress thallium test. Should I go for?
Yes: With known history of coronary artery disease and prior angioplasty and coronary bypass surgery, any new chest pain/discomfort should be evaluated and frequently a nuclear stress test can be helpful to figure out if a chest pain syndrome is related to coronary ischemia- "blockage" or obstructive narrowing of a coronary artery or CABG graft. Thallium or technetium based nuclear testing can be used ...Read more
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
Very common: A thallium stress test is an extremely common procedure that allows the doctor to monitor the electrical activity in your heart while you walk on a treadmill with a continuous ekg (usually takes 10min) and to take "before and after pics" of your heart. Pictures are taken before and after walking to see if there is an area of low blood flow, which suggests blockage in a coronary artery. ...Read more
Just you: Wear comfortable clothes and walking shoes (assuming it is an "exercise" not "chemical" stress). Don't eat or drink anything after midnight. Don't smoke for at least 4 hours before the test, and ask your doctor if you should adjust your morning medications (particularly Insulin if diabetic or a beta blocker — which is a blood pressure medication). ...Read more
Stress with Thallium: A radioactive isotope of thallium, often 201, is injected iv. Heart muscle cells pump some radioactive thallium inside; less if blood flow past the cells is limited. Thus, cells (or scar tissue) with low blood flow intake less thallium & emit less radiation. A gamma camera detects some radiation which exits the body. Only severe, not mild, artery disease complications can be detected. ...Read more
No: Thallium is a low frequency, low penetration radiation. Nothing to worry about. ...Read more
No: I have had many of these and other than fatigue on the treadmill, no problems. ...Read more
Thallium: It is safe for a well treated epileptic to have a thallium perfusion study. ...Read more
Depends on symptoms: Acute coronary syndromes, complete w chest pain, ECG changes, and biomarker elevation are an indication for catheterization and possible stent implantation without additional testing. Short of acute symptoms, noninvasive testing (such as myocardial perfusion imaging, or stress echocardiography) help define a clinical need to assess for a physiologically significant coronary obstruction. ...Read more
Which test is more accurate a cardiac petscan or thallium stress test? Why is one or the other chosen by cardiologists?
PET over thallium:
Both tests use nuclear isotopes. The isotope used in pet scans has better visualization/resolution characteristics than thallium which is a spect study (like technetium). Tissue viability is also superior in pet as compared to thallium.
The problem is usually that pet is done in fewer cardiology systems than spect (technetium or thallium)
of the spect scans, technetium is superior to thallium. ...Read more
Left sided chest burning / tearing sensation when spontaneously exert or walk fast. Neg thallium stress test in 2009 and 2013. Echo showed mvp. Ideas?
Inner left arm ache. Two weeks now. Armpit to hand. Tricep aches as well. Normal thallium stress test 04/09 and pet st 01/13. Cardiac? Nerve? Thanks
Ache: Your ache is highly unlikely to be cardiac, far more likely to be musculoskeletal. ...Read more
