STEM/NSTEMI Flashcards
When do you not give nitrates in a patient with STEMI
When ecg shows inferior STEMI as they may precipitate severe hypotension
Stepwise management of a patient presenting with Angina symptoms
-Stabilise ABCs, IV access, attach monitors
- O2 titrated to Sats 94-98%. Hyperoxia can be harmful in ACS.
- ANTI-PLATELET THERAPY:
Aspirin 300mg stat chewed, then 150mg daily.
It blocks platelet activation by limiting TXA production via the cyclooxygenase pathway.
↓ mortality by 25%
Clopidogrel (Plavix) 300mg stat, then 75mg daily if aspirin allergy - NITROGLYCERIN:
No demonstrable survival benefit with NSTE-ACS.
Helps with vasospasm.
Don’t give if contra-indicated.
Isordil 5mg SL or Tridil infusion
MORPHINE:
For pain.Give small,regular IV doses.
Retrospective data suggests ↑ morbidity among NSTE-ACS patients.
- β-BLOCKERS:
Start within 24hrs of presentation.
Avoid in CCF, low cardiac output states. - ANTI-COAGULATION:
LMWH: Enoxaparin (Clexane) - 1mg/kg SC 12hourly.No monitoring necessary.
UFH: Heparin - less effective than clexane. Need to monitor PTT

- Arrhythmia eg. VF,VT,AF,accelerated idioventricular rhythm,AV block,etc.
- Acute heart failure
- Cardiogenic Shock
- Mitral regurgitation

(Look at their ECGs)
Management of NSTEMI
