WebThe timeframe between symptom onset and reliable detection of very low concentrations of troponin (or concentration changes) can now be much shorter. This has led to clinical pathways that incorporate troponin measurement at 0 and 6 hours then 0 and 3 hours, using the 99th percentile as a decision threshold. WebElevated levels of cardiac enzymes (cardiac biomarkers) in the blood are a sign of heart damage, stress or inflammation. Your heart releases these proteins after a heart attack. Your heart may also release cardiac biomarkers when low oxygen levels cause the heart to work harder than usual. An enzyme marker test (blood test) measures heart enzymes.
