Outline• Pick your/cardio’s strategy• Initial therapy...for everyone?• Pick an anti-platelet...or two...or three...• Protect the stomach??? PPI controversy• Pick the right anti-coagulant• Send home the lucky stable one
Evidence? Says Who?
First, conservative or invasive?
ASA
Nitrates
Morphine
Beta Blockers: the good
Beta Blockers: the bad
CCB
CCB dosing
Ace i
Ace i: Is more better?
Lets talk anti-platelets...
Plavix
Plavix: How much?
Prasugrel?
Ticagrelor?
Plato Controversy
Plavix vs GP IIb/IIIa inhibitor
What about adding a PPI?
Anti-Coagulants
• Indirect inhibitors of coagulation (need antithrombin for their full action)– Indirect thrombin inhibitors: UFH; LMWHs– Indirect factor Xa inhibitors: LMWHs; fondaparinux
• Direct inhibitors of coagulation– Direct factor Xa inhibitors: apixaban, rivaroxaban,
otamixaban– Direct thrombin inhibitors (DTIs): bivalirudin, dabigatran
Bleeding risks
UFH
LMWH
Bivalirudin
Fondaparaneux
Discharge
Take Home Points
• Initial therapy for everyone – think ASA and nitrates– Be careful with BB, CCB, morphine– Consider ace inhibitors
• Pick an anti-platelet...or two...or three...– Plavix in everyone at 300mg– Talk to cardio about prasugrel or ticagrelor– Leave the GPI until they go to PCI
• Protect the stomach!– PPIs show more benefit than harm
• Pick an anti-coagulant– UFH if high risk or going to CABG– Enox or Bivalirudin if going to PCI– Fonda if conservative strategy or high risk for bleeding
• For the ones sent home...– ASA and Plavix for at least 1 month– Stress test within 72 hours
