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.
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
Typically not: The only "risk" would be during the stress part, when one runs on a treadmill or gets a drug alternative. However, there is little risk here because this is monitored with an ekg and supervised by a cardiologist/nuclear physician. One drug that is used for stress even has an agent that can reverse its side effects. In summary, under normal standard-of care-conditions, there should be little risk.
Need more specifics: What specific results would you like help with?
Nuclear test: It means the images on the test were not normal. You need to discuss with your doctor what the test implications are for you. It isn't so straightforward that one can know from out here.
Do I need to have any more testing for blockages with a negative nuclear stress test? Or is this sufficient?
Nuclear stress test results came back normal. However, i'm still feeling symptoms. Am I just being dumb? Should I just be content w/the results?
Not Dumb.: If the stress test test is negative, you still need to find why you are having symptoms. All you have done is found a reason you are not having them.
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.See 1 more doctor answer
Yes: You are not a nuclear reactor. (: take care.See 1 more doctor answer
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
No: Not at all!Get a more detailed answer ›
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.See 1 more doctor answer
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.See 1 more doctor answer
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?
How long does it take to get results back from a nuclear stress test? I had one two weeks ago for some symptoms, and haven't recieved a call yet?
Unacceptable: Clearly something fell between the cracks. Give the office a call.See 1 more doctor answer
If i'm too weak to do the exercise nuclear stress test next week will they do the injection kind? I'm worried I won't be able to. Havent been eating.
Discuss with Cardio: If you are feeling more weak than prior to having the stress test scheduled, I would recommend you have a doctor examine you right away. It could be a sign of worsening health (possibly your heart). If this has been an ongoing concern, however, please consider discussing your limitations with the Cardiologist. They can inject you with "dipyridamole" which puts similar stress on your heart.
testing: Your dr. Should be the source of which test is most appropriate for the information which he needs to take care of your situation. Tests are ordered to answer questions, out here we don't know your situation.
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
