Question Title: Accuracy of interpretation of Thallium Stress Test

Question: how reliable are the interpretations of the thallium stress test? Is there a tendency of cardiologists to view the results as indicating angioplasty when diet/medicines/vitamins/exercise/stress reduction present at least as valid a treatment plan?

Dear Barry,

Q: how reliable are the interpretations of the thallium stress test?
A: The sensitivity (ability of the test to detect disease) is about 85% and the specificity (the ability of the test to detect normals) is 85-90%. Thus there is the possibility of a "false positive" that is the test says there is disease when there in fact is no disease or a "false negative" where the test says there is no disease and there is disease present.

Q: Is there a tendency of cardiologists to view the results as indicating angioplasty when diet/medicines/vitamins/exercise/stress reduction present at least as valid a treatment plan?
A: This is an excellent question and one that you would get many different opinions on depending on who you ask. I would not rush into any procedure you do not feel comfortable with. If you are unhappy with the answers your current cardiologist is giving you, you may consider seeking a second opinion. Hope this helps. Please feel free to write back with any additional questions.
