New diagnosis or history of objectively documented HIT/HITTS Type II, defined as:
1. Positive heparin-induced platelet aggregation (HIPA) or other functional assay for HIT or immunoassay for HIT antibodies (ELISA), AND/OR
2. HIT: Thrombocytopenia associated with heparin therapy, where the platelet count has decreased by 50%, OR
3. HITTS: Thrombocytopenia (as defined in B above) PLUS any arterial or venous thrombosis (Deep-vein thrombosis, pulmonary embolism, mesenteric venouse or arterial thrombosis, acute myocardial infarction, left ventricular thrombus, ischemic stroke, or occlusion of limb arteries) diagnosed by physical exam/lab evidence and/or appropriate imaging studies (duplex ultrasound, venography, ventilation-perfusion scan, venouse or arterial angiography, MRI/MRA, catheterization.)
You may not be if
Confirmed pregnancy, by urine or serum pregnancy test (if woman of child-bearing potential).
Cerebrovascular accident within 6 months, or any cerebrovascular accident with a residual neurological deficit.
Intracranial neoplasm, arteriovenous malformation, or aneurysm.
Dependency on renal dialysis or creatinine clearance \<30mL/min.
Ongoing treatment with warfarin (or other oral anticoagulant) at the time of enrollment.
Patients previously treated with warfarin may be enrolled if warfarin therapy can be safely discontinued and baseline INR is \< 1.3 times control in the absence of heparin therapy.
Known allergy to Angiomax or hirudin derived drugs, or known sensitivity to any component of the product.
Patients receiving clopidogrel (Plavix®) within the previous 5 days may be enrolled if in the opinion of the Investigator the benefits of surgery outweigh the risk associated with recent clopidogrel administration.
Patients receiving a glycoprotein IIb/IIIa inhibitor within the previous 48 hours if abciximab (ReoPro®) or 12 hours if eptifibatide (Integrilin®) or tirofiban (Aggrastat®), may be enrolled if in the opinion of the investigator the benefits of surgery outweigh the risk associated with not waiting the 48 or 12 hour time period prior to enrollment.
Patients receiving lepirudin (Refludan®) or argatroban within the previous 24 hours prior to enrollment. Patients currently receiving lepirudin or argatroban can be enrolled if they are switched to Angiomax at least 24 hours prior to the contemplated OPCAB.
Patients receiving low molecular weight heparin (LMWH) or thrombolytics within the previous 12 hours may be enrolled if in the opinion of the Investigator the benefits of surgery outweigh the risk associated with not waiting the 12 hour time period.
Participation in other clinical research studies involving the evaluation of other investigational drugs or devices within 30 days of randomization.
Refusal to undergo blood transfusion should it become necessary.
Any other disease or condition, which, in the judgment of the investigator would place a patient at undue risk by being enrolled in the trial or inability to comply with study requirements.
