Could nuclear stress tests be false?

Could nuclear stress tests be false?

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

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

Nuclear stress test for type b WPW syndrome?

Nuclear stress test for type b WPW syndrome?

Not helpful: A nuclear stress test will provide information regarding the health of your coronary arteries which have nothing to do with wpw. If a stress test is indicated, it's independent of wpw. If WPW is the issue, a stress test will provide no useful information. ...Read more

Nuclear stress test and cardiac coronary CT angiogram, which do you recommend?

Nuclear stress test and cardiac coronary CT angiogram, which do you recommend?

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

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?

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?

Tests: in your age group the tests you had suggest that you presently have no significant problems with coronary blood flow. You won't get a guarantee for the future but good diet, exercise along with no smoking and medical follow up will be prudent. ...Read more

How accurate are nuclear stress tests, and what does a negative result mean? No ischemia? No detectable ischemia?

How accurate are nuclear stress tests, and what does a negative result mean?  No ischemia?  No detectable ischemia?

Good, not perfect: You've asked an excellent question about which books are written. The accuracy depends on the likelihood that pathology is present and the prevalence of the disease in the population studied. Broadly, a negative test is 80% accurate but can lower your chance of disease from >60% to <20%. Practically, let your doc decide for you based on your unique issues whether more tests are indicated. ...Read more

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

Could sestamibi nuclear stress test only evaluates left ventricular function?

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

My stress test results read " positive exercise stress test for ischemia by EKG criteria. What does that mean?

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

I have had regular stress test. Nuclear stress test echocardiogram and heart catherization. All normal what's chance missed blockage or pulm htn?

Zero: There's no chance for blockage. If your pulmonary artery pressure was reported on your echo, than there's no chance that's been missed either. ...Read more

Best non invasive test to check coronary arteries? Ct angio, stress echo and cardiac MRI MRA? Any better non invasive testing to check coronary art?

Best non invasive test to check coronary arteries? Ct angio, stress echo and cardiac MRI MRA? Any better non invasive testing to check coronary art?

Tests: Each of the tests listed has specific strengths and weaknesses. The choice of study depends on the specific information desired by the ordering physician and the capabilities of the performing laboratory. CT angio in many cases will produce the best images of the arteries of the three, MRA has its specific indications and stress echo doesn't show the vessels but shows the effects of serious ischem ...Read more

Is thallium stress test a very common procedure?

Is thallium stress test a very common procedure?

Very common: A thallium stress test is an extremely common procedure that allows the doctor to monitor the electrical activity in your heart while you walk on a treadmill with a continuous ekg (usually takes 10min) and to take "before and after pics" of your heart. Pictures are taken before and after walking to see if there is an area of low blood flow, which suggests blockage in a coronary artery. ...Read more

Normal D-Dimer lab, cardiac echo shows mild RCA blockage , physican ordered a nuclear stress test . I am a Paramedic ,can you code with a stress test?

Normal D-Dimer lab,  cardiac echo shows mild RCA blockage , physican ordered a nuclear stress test . I am a Paramedic ,can you code with a stress test?

Unlikely: The long answer is that you have a stressful job and you are frequently in situations that cause emotional and physical stress. You should be fine. They will be monitoring you during the test. Also, if the test were that risky, we would not do it so often. Even if you do code. You will be on a monitor in a medical facility with the ability to resuscitate. ...Read more
