Had a nuclear stress test done today. Due to dvt, couldn't do treadmill instead they used lexiscan. Read about lexiscn leading to heart att. Worried.

Don't Worry Be Happy: The risks you were worried about relative to the Lexiscan injection would have occurred during the test. Such risks are present for any stress test which is why they are always done with a physician and resuscitation equipment available. Every test we take or don't take is associated with some risk. We try to balance risk vs benefits. ...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

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

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?

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

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

Stress Test (Definition)

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
