Figure 7 Algorithm for Patients With UA/NSTEMI Managed by an Initial Invasive Strategy

When multiple drugs are listed, they are in alphabetical order and not in order of preference (e.g., Boxes B1 and B2). *See dosing Table 13. See Table 11 for selection of management strategy. Evidence exists that GP IIb/IIIa inhibitors may not be necessary if the patient received a preloading dose of at least 300 mg of clopidogrel at least 6 h earlier (Class I, Level of Evidence B for clopidogrel administration) and bivalirudin is selected as the anticoagulant (Class IIa, Level of Evidence B). ASA = aspirin; GP = glycoprotein; IV = intravenous; LOE = level of evidence; UA/NSTEMI = unstable angina/non–ST-elevation myocardial infarction; UFH = unfractionated heparin.
