Argatroban, Bivalirudin, and Lepirudin do not Decrease Clot Propagation and Strength as Effectively as Heparin-activated Antithrombin In Vitro

DTIs demonstrated a significant prolongation of clot initiation but poor attenuation of propagation and strength. Further in vitro and clinical investigations to design a heparin-equivalent regimen to provide anti-coagulation for patients with heparin-induced thrombocytopenia are indicated.
