1

Low Hb (Haemoglobin)

Anaemia

2

CRP >200mg

Indicates severe infection

3

Troponin

Released during MI after myocyte injury

Released 2–4 hours after
Peak: 12 hours
Normal within 7 days
Very high specificity

Will be normal in angina- so this is the differential between NSTEMI and angina. Differential between STEMI and NSTEMI is ST-elevation!

4

Creatine Kinase

Released after MI

Peak: 10-24 hours
Normal within 2-3 days
High specificity

5

Lactate Dehydrogenase (LDH)

High LDH-1 compared to LDH-2 suggests MI

Can also be: Cancer, meningitis, encephalitis and HIV

Peak: 72 hours
Normal within 10-14 days
High specificity

6

Myoglobin

Rises in muscle tissue damage
Peak: 2 hours
Low specificity
