WebOne of the key benefits of high-sensitivity troponin is the ability to measure both very low concentrations and changes to low concentrations with high precision and confidence. The timeframe between symptom onset and reliable detection of very low concentrations of troponin (or concentration changes) can now be much shorter. WebApr 1, 2024 · The concentration of high-sensitivity troponin T measured can vary markedly after a marathon run (shaded area) and can even supersede that of, for example, NSTEMI. In chronic heart failure (CHF) troponin concentrations are persistent and often not elevated in the absence of an ischaemic episode.
