An intern on your service requests a serotonin release assay test as well as solid phase immunoassay for heparininduced antibodies. The results of the serotonin assay test comes back positive, whereas those of the solid phase immunoassay returns negative.

She does not have any evidence of ischemia and appears to be well. An intern on your service requests a serotonin release assay test as well as solid phase immunoassay for heparininduced antibodies. The results of the serotonin assay test comes back positive, whereas those of the solid phase immunoassay returns negative. The patient continues to do well and is discharged and returns to your office in 2 weeks. At that time, her platelet count is 100,000 and she is asymptomatic but continues to smoke and is not interested in losing weight. Her medication regimen includes ASA, clopidogrel, atorvastatin, atenolol, and lisinopril. Eight months later, on the same medication regimen, she returns to your clinic complaining of chest pain and undergoes a stress test, which shows a large anterior ischemia. She undergoes catheterization and is found to have 85% stenosis of LAD. What should her antithrombotic regimen be? (A) Heparin and GP IIb/IIIa inhibitor (B) LMWH and GP IIb/IIIa inhibitor (C) LMWH alone since she is already on clopidogrel (D) Argatroban
