*Cardiac Troponin I*
Safe way to Triage chest pain!
The diagmosis of cardiac emergencies is one of the most crucial tasks delegated to physicans. The broad differential diagnosis of chest pain must be narrowed to perform life-saving treatments.
- Cardiac Troponins are cardiac regulatory proteins that are found in the cytoplasm of cardiac myocytes.
- Cardiac Troponin I is found exclusively in cardiac muscles.
- Troponin levels start to elevate in circulation within 2-3 hours of the onset of chest pain. They reach peak between 12-48 hours and begin to fall over next 4-10 days down to normal.
- Troponin level greater than 0.6 ng/mL has 94% sensitivity and 81% specificity for the diagnosis of acute myocardial infarction.
