Antiphosphatidylserine Antibody as a Cause of Multiple Dural Venous Sinus Thromboses and ST-Elevation Myocardial Infarction.

BACKGROUND Antiphospholipid syndrome (APS) is an autoimmune disease characterized by antibodies directed against phospholipids on plasma membranes. Through unclear mechanisms, APS confers hypercoagulability. APS may cause recurrent thromboses in the arterial and venous vasculature.
