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
