Diagnostic accuracy of troponin T measured ≥6h after symptom onset for ruling out myocardial infarction.

Conclusion: A single hs-cTnT ≤14 ng/L obtained ≥6 h from chest pain onset, with and without GRACE score, reliably ruled out MI but did not perform well for ruling out 30-day MACE. These results question current guideline recommendations, and indicate that HEART, EDACS, TIMI, or ECG + patient history strategies should be the preferred risk stratification tools.
