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

Could you go through the airport scanners after the myocardial perfusion scan?

Could you go through the airport scanners after the myocardial perfusion scan?

Indeed: However it would be a good idea to ask your cardiologist for a letter attesting to your test, the time, the isotope used, the half-life of that isotope, etc. The most commonly used isotope is technitium sestamibi 99 which has a half-life of only 6 hours, however when this radioactive isotope is in short or limited supply, thallium is often substituted, which has a half life of over 73 hours. ...Read more

Can someone have a myocardial perfusion scan with a pacemaker?

Can someone have a myocardial perfusion scan with a pacemaker?

Yes: Yes, patients with implanted pacemakers have nuclear stress tests/myocardial perfusion scans. The EKG portion of the test will reflect the pacemaker (and likely a left bundle branch block) but reversible ischemia can still be detected in the scans. ...Read more

Could you have a myocardial perfusion scan if you suffer from myoclonic dystonia?

Stress test: It is paramount that the patient is completely still when undergoing myocardial perfusion scanning -- therefore if the myoclonic dystonia is well controlled then you could probably have the scan -- otherwise you have other option of stress and imaging modality. ...Read more

Could you have a myocardial perfusion scan after a cataract operation?

Could you have a myocardial perfusion scan after a cataract operation?

Yes: Modern day cataract surgery is minimally invasive and can even be done with just eye-drop (topical) anesthesia. While an implant (silicone or acrylic) is placed during the surgery, there are no restrictions on any future nuclear imaging, mri, ct scan etc.. ...Read more

Is there any risk of radiation poisoning after myocardial perfusion scan?

Is there any risk of radiation poisoning after myocardial perfusion scan?

No: Radiation poisoning occurs at exposures of 1000 msv and greater ( http://sgoti.Ws/plwzai ). The radiation exposure from a myocardial perfusion scan is around 10 msv and has never been shown to be harmful, although it is recommended to only get medical imaging performed when appropriate in order to minimize any theoretical cumulative risks of radiation. ...Read more

Is it safe to have a myocardial perfusion scan done without a cardiologist?

Is it safe to have a myocardial perfusion scan done without a cardiologist?

Probably: At some hospitals, physicians assistants are who is actually present during the study. As these tests usually involve some type of stressing of the heart, it is important that whoever is supervising the test has the knowledge to make the decision that the patient is stable and that it is safe.. In most cases, a cardiologist has had some input in that decision even if not there for the test. ...Read more

How does caffeine affect the results of thallium myocardial perfusion scan?

How does caffeine affect the results of thallium myocardial perfusion scan?

Not usually: Caffeine in the usual dietary dose won't affect an exercise stress test with thallium imaging, but if you ingest caffeine recently you cannot have a stress test with pharmacologic stress using Persantine (dipyridamole), Adenosine or Lexiscan because the caffeine interferes with the metabolism of those agents. ...Read more

What are common side effects from the radioisotope in a myocardial perfusion scan?

None: There are no common side-effects from the radioisotope. There have been very rare reports of allergy. There is a theoretical, but unproven risk of the radiation inducing a cancer 10 to 20 years later. There also is a theoretical, but unproven risk of radiation myocarditis. The radiation exposure of 1 rem (about 10 msv ) has not been shown to be harmful. See http://sgoti.Ws/qmhwh7. ...Read more

Can I eat food before having myocardial perfusion scan?

No: No because the blood flow to stomach increased and it makes the image less accurate. ...Read more

What is the definition or description of: myocardial perfusion scan with exercise?

What is the definition or description of: myocardial perfusion scan with exercise?

Cardiac Exam: Myocardial perfusion imaging looks at blood flow to the left ventricle. This is primarily accomplished using nuclear techniques such as pet or spect using radiotracers such as tl-201, tc-99m, or n-13 ammonia. When it is done with exercise, the myocardial perfusion scan shows blood flow during exercise, and usually compares that to perfusion at rest in order to evaluate for inducible ischemia. ...Read more

Are there any side affects after having a myocardial perfusion scan if so can you tell me please?

Are there any side affects after having a myocardial perfusion scan if so can you tell me please?

Radiation...: Depending on what radiotracer is used, you will be exposed to a small amount of radiation but the benefits of the test should outweigh the risks. Are you having pharmacologic or exercise test? Some of the pharmacologic agents can cause some side effects such as bronchoconstriction but a medication called aminophylline can usually be administered to reverse the side effects. ...Read more

What is the point of a myocardial perfusion scan [nuclear test]?

What is the point of a myocardial perfusion scan [nuclear test]?

Cardiac imaging...: The myocardial perfusion scan is performed mostly to detect ischemia. It can also detect infarction (heart attack) as well as ejection fraction, wall motion abnormalities, and ventricular volumes. ...Read more
