Study Notes
Cardiac Markers for AMI
- Primary Markers for Acute Myocardial Infarction (AMI): Troponins (T and I) are the most specific.
- Troponins: Released when heart muscle is injured.
- Troponin I (cTnI) and Troponin T (cTnT):
- cTnT binds to tropomyosin.
- Normal value for cTnT is not provided.
