What is the purpose of measuring cardiac troponin levels?
Cardiac troponin levels are measured to provide prognostic assessment beyond that of clinical information, the initial ECG, and the predischarge. Troponin elevations are useful for short- and long-term prognosis, and can provide information to direct therapy. Persistent elevation 72 to 96 hours after symptom onset may afford relevant information in estimating infarct size and risk of death.
