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

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

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 is persantine stress test done for?

Test for blockages: Persantine is used to augment changes seen in stress testing when coronary arteries have a blockage that limits flow. ...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

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

What is rest stress thallium test?

What is rest stress thallium test?

Heart Disease Test: Thallium stress test is a nuclear imaging method that shows how well blood flows into the heart muscle, both at rest and during activity. Normal blood flow would "light up" on images. The stress portion is either through exercise, like on a treadmill, or a drug can be injected for those who can't tolerate regular exercise. This causes the heart to behave as if the subject were exercising. ...Read more

How effective are exercise stress tests at diagnosing heart disease?

85 - 90 %: If the stress test is combined with nuclear imaging, the sensitivity for picking up on coronary artery disease is 85-90%. If the stress test is done without imaging, the sensitivity is less. In interpreting stress test results, it is important to note the "pretest likelihood of disease". In a young healthy patient, a positive result is likely to be a false positive. ...Read more

Normal stress echo with no evidence of stress induced myocardial ischemia but abnormal exercise stress at 9.1 mets? Reached 94% of hr.

Ur initial ST: Is more likely false positive.With ur young age and i presume with no risk factors like hypertension , diabetes, high lipids ; strong family history of heart disease, i won't worry about it.

Stress test or heart cath for beter results ?

Stress test or heart cath for beter results 
?

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

Nuclear stress vs regular stress test, which one to choose or just follow yr doc instructions?

It depends: There are differences and guidelines on choosing. Given the lack of specifics in the question, I recommend to follow your doctor's recommendations especially if you trust their judgement. If that's a question, consider a second opinion. ...Read more

Exercise Stress Test (Definition)

Recording an ekg while walking up a steeper & steeper incline, at a faster & faster rate, so as to increase heart contraction intensity & rate of contraction, thus blood flow needed by the heart muscle. However, atherosclerosis does not narrow arteries, clots do, & the ekg only detects major qualitative differences in capillary blood flow. Thus only severe artery disease ...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
