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

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

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

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

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

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

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

Stress ECG abnormal but coronary angiogram normal, any other test (e.G echo) to ruled out underlying heart disease?

Stress tests: Have higher false positive (and false negative) rate than we'd like to admit. Try getting a session of multifunction cardiogram instead. It is a very accurate stress, radiation and drug free heart test! http://en.M.Wikipedia.Org/wiki/multifunction_cardiogram. ...Read more

Stressechoresults: abn stress ECG at 9.1mets, normal exercise stress echo with no evidence of stress induced myocardial ischemia. What does this mean?

Probably normal: The ECG is accurate about 70-80% of the time in diagnosing cad. Adding stress echo or nuclear imaging improves accuracy to above 90% when patient reaches his or her target rate. ...Read more

What all does a heart ultrasound, holter and heart stress test detect?

What all does a heart ultrasound, holter and heart stress test detect?

Many things. : The echocardiogram or heart ultrasound, gives an accurate picture of the heart's anatomy. An ekg demonstrates the cardiac rhythm. A holter moniters the cardiac rhythm over time- say 12 or 24 hours. These measure different aspects of heart function and are helpful in assessing heart function thoroughly. ...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

What would an echo stress test show....That a regular echo test doesn't?

Change w/exercise : When excercised, or 'stressed', the heart needs more oxegen to function properly than at rest. If it's not getting that increase, the muscle will start to move in abnormal ways, which will show up on the echo. At rest, because it needs less oxegen, it may be getting enough, so it will look normal then. ...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

Stress Test (Definition)

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
