[Acute coronary syndrome (without ST-elevation)].

Antithrombotic therapy in acute coronary syndrome without ST-segment elevation should be initiated with aspirin 100 mg/day (loading dose 250-500 mg) and Clopidogrel 75 mg/day (loading dose 300 mg). In addition, anticoagulation with unfractionated heparin or low molecular weight heparin should be started. A GP IIb/IIIa receptor blocker can be given either upfront (Eptifibatide/Tirofiban) or directly in the cathlab preceding PCI (Abciximab). Aspirin should be given in the chronic phase lifelong, Clopidogrel for at least nine months. An invasive strategy is recommended in high-risk patients within 48 hours.
