What is the persantine sestamibi stress test?

What is the persantine sestamibi stress test?

See below.: This is a chemical stress test of blood flow to the heart muscle. It is used to evaluate patients who are unable to exercise. Pictures of blood flow are obtained before and after the stress. Post stress abnormalities may indicate narrowings of the coronary arteries which impede blood flow and may be a cause of chest pain. Abnormalities of flow before stress may indicate previous damage. ...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

What is the sestamibi stress test?

See below: A sestamibi stress test is used to detect decreases in blood to the heart muscle during exercise or chemical "stress." such decreases in flow may indicate partial or complete blockage of one or more of the coronary aeries that supply blood to the heart muscle. ...Read more

What is the sestamibi stress test with adenosine?

What is the sestamibi stress test with adenosine?

MPS: I believe you are referring to a myocardial perfusion scan, where technitium sestamibi 99 is the radioactive isotope that is injected intravenously so that images can can be taken of the heart at rest and 'stressed' or exercrsing -which brings us to the adenosine: a pharmacological agent used to 'stress' the heart instead of walking on a treadmill. Lexiscan is the stress agent of choice now. ...Read more

What is the sestamibi treadmill stress test?

What is the sestamibi treadmill stress test?

Nuclear study: This is a nuclear medicine test that tells your physician about your heart function. A small amount of nuclear tracer is given right after/during running on a treadmill followed by a scan. This is compared to a similar scan performed at a separate time under resting conditions. Any decreased area of tracer uptake in the heart during stress compared to rest indicates a possible artery block. ...Read more

Could sestamibi nuclear stress test only evaluates left ventricular function?

NO: Nuclear stress test are done to evaluate coronary circulation/ blockages/CAD. As lagniappe they provide info re LV function. However, there are less expensive and invasive test that evaluate LV function just as well or better, like echocardiography ...Read more

What's the difference between a lexiscan stress test & a stress echo dobutamine test? I have had the lexiscan before.

What's the difference between a lexiscan stress test & a stress echo dobutamine test? I have had the lexiscan before.

Nuclear/ Echo stress: Lexiscan stress generally performed with nuclear isotope, which shows blood circulation (perfusion), comparing with medication lexiscan (stressing heart) and at rest. Dobutamine echo we are looking at wallmotion of heart with medication dobutamine (stressing heart)and at rest to see they show any differences to detect blockages ...Read more

Had a stress test done and my target heart rate was 190 but when injected with lexiscan my heart only did 175 is that good or bad?

Max predicted HR...: Exercise stress testing requires that the patient reach 85% of maximum predicted heart rate. Maximum predicted heart rate is given by equation (220-age). If adequate heart rate is not achieved then pharmacologic (lexiscan) stress test can be performed. ...Read more

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

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

I had an echo and Stress test was normal echo showed mild mitral and triscupid regurgitation, normal LV size and R/S occasional PAC's. Is this normal?

Question? Consult!: These little boxes are not good for answering specific patient case problems. Consider a cardiology consultation here on HealthTap. The kind of consult where you ask for help within the next 24 hours works particularly well for a complex case because it enables emailing back and forth with the details. ...Read more

What does it mean if your stress test is negative?

"negative" is good: A "negative" stress test means the absence of what is being tested for--i.e. No signs of flow-limiting blockages in coronary arteries. In other words, the heart muscle is getting plenty of blood flow. It's important to note that a normal stress test does not mean the absence of underlying non-obstructive coronary disease. Detecting this may require other tests, depending on your risk profile. ...Read more

Can I take ibuprophen before a stress test?

Yes: Yes, I don't find any research that has Ibuprofen listed as a med to not take before an exercise or nuclear stress test.

There are several heart medications to avoid the day of and before as well but check with your doc ...Read more

What does a Q wave on a stress test represent?

Heart Damage: A "q wave" is seen on an electrocardiogram (ekg) several of which are recorded during a stress test. Q waves may be very small and not carry much significance or may be larger and suggest that heart damage by a heart attack has occured at some point in time. Further testing and imaging of the heart may be required to determine if the Q wave is significant. ...Read more
