- This calculator is designed for use with high Sensitivity Troponin T (TnT-hs)
- Delta troponin is the percent difference between two troponin results taken in the same
patient within a 3 - 8 hour time period.
- A delta troponin > + / - 30%, with one value for TnT-hs >14 ng/L, is
consistent with an Acute Myocardial Infarction in the right clinical setting.
- Delta troponin is a continuous variable, ie a more rapid rise (or fall) is more
suggestive of AMI than a smaller rise or fall.
- Delta troponin must be interpreted in the context of timing since the onset of symptoms.
During an AMI troponins rise rapidly from abotu 2 - 6 hours after the onset of symptoms to
a peak at 18 - 24 hours followed by a fall over 7 - 10 days.
- In other clinical settigns troponins typically change more slowly or have a delta value
less than 30%.
