Figure 11 Long-Term Antitcoagulant Therapy at Hospital Discharge After UA/NSTEMI

*For aspirin (ASA) allergic patients, use clopidogrel alone (indefinitely), or try aspirin desensitization. For clopidogrel allergic patients, use ticlopidine, 250 mg by mouth twice daily. Continue ASA indefinitely and warfarin longer term as indicated for specific conditions such as atrial fibrillation; LV thrombus; cerebral, venous, or pulmonary emboli. When warfarin is added to aspirin plus clopidogrel, an INR of 2.0 to 2.5 is recommended. INR = international normalized ratio; LOE = Level of Evidence; LV = left ventricular; UA/NSTEMI = unstable angina/non–ST-elevated myocardial infarction.
