The arterial platelet thrombus contribute to development of thrombotic complications of atherosclerosis: acute coronary syndrome, thrombotic strokes and exacerbations of peripheral arterial occlusive disease. Platelet adhesion and aggregation is mediated by interaction between platelet glycoprotein receptors GPI b/IX GPII b/III a and their ligands-adhesive proteins: von Willebrand factor (vWF) and/or fibrinogen. Pharmacological blockade of interaction between glycoproteins receptor and their ligands may offer an effective prevention of thrombotic complications.
