High-Sensitivity Troponins Associated with Exercise-Induced Myocardial Ischemia

December 29, 2015

BASEL, SWITZERLAND — Levels of high-sensitivity (hs) cardiac troponin I may help clinicians detect exercise-induced myocardial ischemia in patients suspected of having the condition, according to new research.

In the 800-person cohort study conducted in Switzerland, those with exercise-induced ischemia, as measured by perfusion single-photon emission computed tomography (SPECT) and coronary angiography, had significantly higher concentrations of hs-troponin I before, during, and after stress testing vs those without the ischemia (P<0.001 for all comparisons).
