Is nuclear stress testing or echo more accurate for calculating ejection fraction? Nuclear says 67 percent echo says 48.

Is nuclear stress testing or echo more accurate for calculating ejection fraction? Nuclear says 67 percent echo says 48.

EF: Ejection fraction can vary depending on the type of test done (echo vs. cath vs. gated nuclear stress). Nuclear MUGA scan is most accurate since is depends on counts rather than the geometry of the ventricle. ...Read more

Stress (Definition)

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

Do I need to have any more testing for blockages with a negative nuclear stress test? Or is this sufficient?

Do I need to have any more testing for blockages with a negative nuclear stress test? Or is this sufficient?

Cardiac stress test: A negative cardiac stress test can be reassuring. However, and depending on your personal and family medical history, and current symptoms, it's best to discuss the need for further testing with your doctor. ...Read more

Will a nuclear stress test make me radioactive? I’m having a nuclear stress test, and i need to know if it’s safe for me to babysit my grandkids after it? Will i be radioactive? Could i be dangerous to the kids?

Will a nuclear stress test make me radioactive? I’m having a nuclear stress test, and i need to know if it’s safe for me to babysit my grandkids after it? Will i be radioactive? Could i be dangerous to the kids?

You : You will be sufficiently radioactive to set off alarms at airports, ferry terminals, and border crossings. The sensitivity of these devices is high on purpose. However, the amount of radiation a patient emits after a cardiac nuclear scan is not considered dangerous to others. Notice that the technologists who perform these tests do not wear lead or other radiation protection and they are around "radioactive" patients every day. For the sake of completeness, however, i will add that pregnant women should not undergo this test and anyone who thinks they might be pregnant should have a pregnancy test before having any kind of radionuclide scan. ...Read more

Please tell me, could nuclear stress tests be false?

YES...: Nuclear stress tests can be false. The two main types of nuclear stress tests are cardiac pet and cardiac spect. Cardiac pet uses ct for attenuation correction which helps get rid of attenuation artifacts which can cause false results. Cardiac spect is often done without ct and therefore often has more artifacts. The radiotracer used (technetium vs. Thallium) also affects the image quality. ...Read more

What is a nuclear stress test?

What is a nuclear stress test?

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

What goes on when having a nuclear stress test?

Pictures: generally take baseline pictures of blood flow in the heart - (lying around for 20 mins), then some sort of stress - exercise or medicine; then post-stress pictures pictures are looking at general blood flow - or lack thereof - which might indicate blockages in arteries. ...Read more

What can you tell me about the cardiolite nuclear stress test?

What can you tell me about the cardiolite nuclear stress test?

Myocardial scan: A cardiac perfusion scan measures the amount of blood supplied to your heart muscle. Radiotracers such as thallium or technetium sestamibi (cardiolite) are injected intravenously and travel through blood to heart muscle.2 sets of images are made during rest and exercise and compared. Indications for this study include chest pain, previous heart attack, heart surgery and coronary artery disease ...Read more

Just had a nuclear stress test done and I have a headache now is that normal?

Lexiscan: The newer stress agent regadenoson (lexiscan) causes less headaches but some still do occur. Often you are told to have no caffeine for 24 hours prior to these tests and the caffeine withdrawal can also cause headache. ...Read more

My cardiology order a nuclear stress test can you explain what is this thanks?

My cardiology order a nuclear stress test can you explain what is this thanks?

Stress test: A nuclear stress test detects blood supply to the heart. A radioactive tracer is injected into the veins at peak exercise or with a vasodilator. The tracer is taken up by the heart cells and the uprake is proportional to blood flow. By comparing uptake at rest versus exercise we can determine if blood flow is compromised. ...Read more

Echo EF is 60 calculated, 55 visual estimate, and 63 on nuclear stress test. What's most accurate?

EF: All three of these numbers are reasonably close and normal. All methodologies have ranges of accuracy and error factors. In theory the nuclear method is the most accurate of these three but again technique can cause error. ...Read more

How often can nuclear stress test be safely repeated, would doing two tests in 4 month be safe. Any radiations concerns. ?

How often can nuclear stress test be safely  repeated, would doing two tests in 4 month be safe. Any radiations concerns. ?

No sig danger: The amount of radiation is pretty minimal. If its indicated, it should be fine but why repeat it after only 4 months? ...Read more
