What does it mean when your stress test comes back inconclusive?

Inconclusive test results were defined as a nonpositive test considered by the site to be nondiagnostic or if maximum achieved heart rate with exercise or dobutamine stress was <85% age-predicted without evidence of ischemia.

What does TMT indicate?

A treadmill test (TMT) or cardiac stress test helps determine how far your heart can go before an abnormal rhythm or blood flow to the heart muscle drops. It helps your doctor know how your heart responds on being pushed. You will be asked to walk on a treadmill, and the difficulty level will be gradually increased.

Can TMT test false positive?

The rate of false positive results is higher when the treadmill test is offered to people with low risk of CAD and lower when offered to people at high risk. His analysis shows that when the treadmill test is included in routine health check-ups, 89 per cent healthy people are likely to have false positive results.

What if TMT test is negative?

A negative TMT or Stress Test is declared when the patient can reach a certain heart rate without showing any ECG changes. This rate is known as target heart rate and it is also calculated by a formula (Target Heart Rate = 220 – age of patient).

Is TMT test conclusive?

“The test result is never, by itself, certain,” Dr. Bhatt says. “It can be used to move the probability up or down of there being coronary artery disease. It can’t absolutely rule it out or diagnose it.”

When is TMT test positive?

What does positive and negative test mean? Positive test means patients ECG is showing changes of angina (lack of adequate blood supply to heart) after workload. It means patient is suffering from ischemic heart disease.

Can TMT test be false negative?

One hundred and fifteen consecutive symptomatic patients undergoing graded exercise testing, selective coronary angiography and left ventriculography were retrospectively evaluated. The sensitivity, specificity, and false negative response rates of the exercise tests were 79%, 81%, and 21%, respectively.

What next if TMT test is positive?

If either of the tests is abnormal then it is better to subject to the patient to angiography. Now, in our case, since her TMT is positive, it is better to subject her for angiography. There is no harm in having stress echo, but suppose it is positive then certainly she will need angiography.

What happens if TMT is positive?

Also, discuss how strongly was TMT positive. If it is strongly positive then nothing to think and go ahead with angiography and if it is mild positive then you may think of stress echo. So overall, it is better to undergo angiography and no harm in stress echo if your doctor insists.
