What is a treadmill stress test used to detect?

Diagnosis: To diagnosis underlying coronary artery disease in one with suggestive symptoms or to evaluate the efficacy of medical therapy in one with known coronary artery disease.

ForAdvancedDisease: Promoted for detecting artery disease, but misses most disease; arteries expand, not narrow. ~75%, or more, narrowing required before stress tests, all forms, begin to detect any abnormalities. Nuclear (more expensive & person radiated) promoted as more sensitive; for all I have seen, a well done ekg exercise stress more sensitive & accurate. I quit doing stress tests 1995; better client options.
