- Myocardial Enzyme Spectrum
-
- [[Lactate Dehydrogenase]]
- [[Creatine Kinase and Isoenzymes CK]]: Not as sensitive as cTnI; if cTnI elevation is caused by non-myocardial infarction (such as infection, heart failure, etc.), CKMB will not rise. Combined, they better determine whether it is myocardial infarction.
- [[Aspartate Aminotransferase]] (less used)
- [[α-Hydroxybutyrate Dehydrogenase]] (less used)
-
- [[Cardiac Troponin cTnI]]
- [[Myoglobin]] (less used)
- [[B-type Natriuretic Peptide BNP]]
| Symptom - Detection Time Gap | Peak Time | Duration | Sensitivity | Specificity | |
|---|---|---|---|---|---|
| Creatine Kinase MB (CK-MB) | 3 - 4 hours | 24 hours | 3 - 4 days | +++ | +++ |
| Troponin T (Troponin T) | 3 - 4 hours | 2 - 3 days | 7 - 14 days | +++++ | +++++ |
| Troponin I (Troponin I) | 3 - 4 hours | 2 - 3 days | 5 - 7 days | +++++ | +++++ |
| High-sensitivity Troponin (hs-TnT or I) | 1 - 3 hours | 2 - 3 days | - | ++++ | +++ |
