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

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

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

Exercise stress test, 24 hour holter monitor, echo doppler test--which is done first?

Exercise stress test, 24 hour holter monitor, echo doppler test--which is done first?

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 more

How is a persantine sestamibi stress test performed?

How is a persantine sestamibi stress test performed?

pharmacologic stress: Often we use other agents but Persantine is injected and the patient is either imaged soon after or after a little exercise, after the Persantine administration, sestamibi is injected to allow the imaging. ...Read more

What's stress thallium test?

What's stress thallium test?

Shows blood flow : thallium is tagged to red blood cells. The heart is stressed (increase cardiac outpu), then nuclear scanning helps show if there is equal blood flow to all parts of the heart, by detecting the radioactive thallium. ...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

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

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

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

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

Caffeine ok while having a chemical cardiac stress test using dipyridamole, persantine?

Caffeine ok while having a chemical cardiac stress test using dipyridamole, persantine?

NO!!!!: Caffeine should not be ingested prior to pharmacologic cardiac stress since it can interfere with the results. Stopping caffeine ingestion for at least 24 hours prior to pharmacologic stress should be sufficient. If caffeine is ingested and pharmacologic stress is performed, this can cause false negative results. If you have taken caffeine, stress may be rescheduled or switched to dobutamine. ...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

Nuclear cardiology stress test--how much radiaiton?

Nuclear cardiology stress test--how much radiaiton?

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 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

Low vs ?Higher Value: Stress tests only capable of detecting very advanced disease, ?chances of heart attack & do nothing to solve issues (i quit doing these 1995). Angiogram with PTCA option has risks (usually small) but can see problems & offers opportunity to open arteries & decrease symptoms at same time. The bigger issues are optimizing lipoproteins (nmr particle test), hba1c & bp, etc. To ??? disease progression. ...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
