O2 (if <94%)
GTN sublingual
Aspirin 300mg

29
Q

STEMI and PCI available within 2hrs

A
  1. 300mg Aspirin
  2. Praugrel
  3. Radial access + unfractionated heparin (+ bailout glycoprotein iib/iiia)
    - Drug eluting stents used
30
Q

STEMI and PCI not available within 2hrs :(

A
  1. 300mg Aspirin
  2. Alteplase (fibrinolysis)
  3. Ticagrelor

*if ST elevation persists after fibrinolysis, send for PCI!

31
Q

Antiplatelet changes when on anticoagulant

A

Praugrel -> clopidogrel

32
Q

STEMI presents >12hrs after onset of symptoms

A

PCI if ongoing myocardial infarction

33
Q

NSTEMI management

A

300mg Aspirin + fondaparinux (if no immediate PCI)

High risk
- PCI (immediate or within 72hrs)
- Prasugrel or ticagrelor
- unfractionated heparin

Low risk
- Ticagrelor

*anticoagulants, swap prasugrel for ticagrelor/ ticagrelor for clopidogrel
**Give unfractionated heparin regardless of fondaparinux

34
Q

Secondary management of ACS

A
  • Dual antiplatelet (aspirin + prasugrel/ ticagrelor) for 12 months
  • ACEi (or ARB) continue indefinitely
  • Beta-blocker (or diltiazem/ verapamil if contraindicated
  • Statins

Conservative
- Cardiac rehabilitation
- Smoking cessation
- Diet
- Physical activity
