Q
Biomarkers for ACS
A
- Troponin
- Creatinine Kinase Myocardial
- useful in re-infarction
- produced by brain, heart, muscle, serum - Myoglobin
- rises and falls very quickly - Fatty acid binding protein
- Coceptin
- Ischaemia modified albumin

A
TnT
TnI
TnC - not cardiac specific

A
- CCF
- Renal failure
- AF
- Myocarditis
- PE
- Electric burns
