Management

Treatment

❑ Administer 300mg Aspirin immediately after hospital admission ❑ Administer oxygen in patients with saturation <90% ❑ Administer nitroglycerine sub-lingual ADD DOSES ❑ Administer morphine IV initial dose 2-4mg with increments of 2-8mg every 5 to 15 minutes ❑ Administer beta-blockers to all patients without contraindications ❑ Administer statins, atorvastatine 80mg ❑ Initiate anti thrombotic therapy

Determine Risk of adverse coronary event (TIMI)

LOW RISK Initial conservative strategy

❑ Administer IV GP IIb/IIIa inhibitors (eptifibatide or tirofiban) OR ❑ Administer Bivalirudin

Perform a Stress test
