Lexiscan Myoview Stress Test
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
Depends on situation: Nuclear stress test involves looking at perfusion of heart for defective areas representing coronary artery disease looking for areas of permanent damage versus areas that are reversible possible related to area of coronary narrowing. Coronary ct angiogram looks at anatomy of coronary arteries looking for areas of narrowing and blockage.Answer depends on information physician needs and insurance. ...Read more
Radiation exposure: There most certainly is radiation exposure with nuclear cardiology stress testing whether it is with thallium, sestamibi, or any of the pet imaging agents. The exposure is minimal but real and the risk vs. Benefit to the patient needs to be considered before ordering the study. Pregnant women should not have these studies and young women can have a very small but increased risk of breast cancer. ...Read moreSee 14 more doctor answers
Had echocardiogram, nuclear stress test w cardiolite, EKG and 30 day holter. Does the echo and nuclear test rule out CAD or any potential blockages?
Yes...: Yes...Nuclear stress tests can have false positive results. There are different types of nuclear stress tests. There is treadmill vs. Pharmacologic and there is spect vs. Pet. There are also many different tracers such as thallium or technetium for spect and ammonia or rubidium for pet. Each type of test has its own possible pitfalls. Artifacts are often the case of false positive. ...Read more
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 moreSee 1 more doctor answer
Better information: A stress echo allows you to view heart function under a stressor. The stress is an elevation in heart rate and produced by the dobutamine. It allows us to see if your blood flow in the coronary ateries can meet demand. Is like economics , supply vs demand. ...Read moreSee 1 more doctor answer
A screening test: Stress tests are largely done to identify patients at risk for heart attacks. For patients who cannot exercise due to arthritis or other reasons, Dobutamine is a drug that will mimic exercise, and allow a stress test to be done. It is not as good as exercise, but it is a reasonable alternative if exercise is not possible. ...Read more
For what?: These tests provide different information and have different indications. Stress tests are to look for evidence to support a diagnosis of symptomatic blocked coronary arteries. Holtor is used to evaluate for dysthymia. Echocardiogram is useful to look at the heart valves and other features. Choosing the right test depends on what symptoms you are having. Discuss this with your doctor. ...Read moreSee 1 more doctor answer
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 moreSee 1 more doctor answer
My stress test results read " positive exercise stress test for ischemia by EKG criteria. What does that mean?
This means that the: EKG portion of your stress test had changes in the waveforms that have been known to be associated with blockages of the coronary arteries. Unfortunately, greater than 15% of the time this is inaccurate in women. Less than 5% of the time in men. This is why we always do stress testing in women along with nuclear imaging. If the nuclear imaging is negative then the EKG changes are FALSE positive. ...Read more
Cardiac MRI, CTPA, EGC 's, echo's, Chest X-rays, PET scan, blood tests, ECG stress test. All these tests, no diagnosis. Could something been missed?
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 moreSee 2 more doctor answers
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 moreSee 1 more doctor answer
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
