How is CV risk assessed in NSTEMI?
- GRACE score to get 6 month CV risk.
- >1.5% clopi for 12 months
- >3% add IIb/IIIa inhibitor e.g. tirofibran.
- give heparin unless going to angio in next 24h (considered if 6 months mortality risk is >3%).
MOA of heparin?
activates antithrombin III which inhibits f Xa.
Standard monitoring of lithium?

How do you interpret Webers test?
- Sound localises to affected side in conductive loss (sound amplifyed on that side!).
- Sound localises away from affected side in sensorineural.
- Rinne's then shows:
- AC>BC = normal
- BC>AC = Conductive hearing loss.
