After taking the Persantine  thallium test my dr., informed me of the following; Decreased count rate in the anterior wall; reversible ischemia;; ?

Cannot be sure it is: While decreased count in the anterior wall may be caused by ischemia( inadequate blood flow), there are frequently other causes. In females, decreased anterior wall counts may be an artifact due to the interposition of the breast between the camera and the heart. In true ischemia ,decreased count would be present only in the stress images. Please confirm this with your physician. ...Read more

What is the risk of the thallium for persantine stress test?

What is the risk of the thallium for persantine stress test?

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

What is the risk of the thallium injected during a persantine stress test?

What is the risk of the thallium injected during a persantine stress test?

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

Is routine dipyridamole thallium scintigraphy still used by doctors?

Is routine dipyridamole thallium scintigraphy still used by doctors?

Yes: In some hospitals it is. But Lexiscan (regadenson) has largely replaced Dipyridamole in most labs. Thallium is also still used sometimes, especially to evaluate hibernatining myocardium, but newer radionuclides have largely replaced it for routine testing. ...Read more

Thallium dipyridamole stress test with the radioactive chemical given is it true that it is dangerous to be near babies and children after procedure?

Thallium dipyridamole stress test with the radioactive chemical given is it true that it is dangerous to be near babies and children after procedure?

No: The amount of thallium given during a stress test is between 20 and 30 times less than the level where you are releasing enough radiation to be of concern. The half life of thallium is short. To be extra careful i wouldn't be worried after 24 hrs at most. ...Read more

What is the difference between persantine and dobutamine?

What is the difference between persantine and dobutamine?

Drugs for Heart Test: Chemical stress tests are used to diagnose heart artery blockage in people who cannot treadmill exercise. Persantine is injected IV and dilates normal blood vessels more than abnormal ones causing an ischemic defect on a nuclear image. Dobutamine is injected IV and increases the heart rate and contractility with muscle fed by a blocked artery not responding as well as normal muscle. ...Read more

What is the persantine sestamibi stress test?

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 more

Caffeine ok while having a chemical cardiac stress test using dipyridamole, persantine?

Caffeine ok while having a chemical cardiac stress test using dipyridamole, persantine?

NO!!!!: Caffeine should not be ingested prior to pharmacologic cardiac stress since it can interfere with the results. Stopping caffeine ingestion for at least 24 hours prior to pharmacologic stress should be sufficient. If caffeine is ingested and pharmacologic stress is performed, this can cause false negative results. If you have taken caffeine, stress may be rescheduled or switched to dobutamine. ...Read more

My cardiologist ordered a myocardial perfusion pet stress test with persantine, so what is it?

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 more

What is rest stress thallium test?

What is rest stress thallium test?

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

What is a thallium stress test procedure?

What is a thallium stress test procedure?

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

Is the thallium stress test a risky thing to do?

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 more

Is thallium stress test a very common procedure?

Is thallium stress test a very common procedure?

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
