Novel antithrombotic strategies in cardiovascular diseases.

Ischemic cardiovascular diseases represent the most common cause of mortality and morbidity in the western world, and atherothrombosis occupies a central role in their pathophysiology. Venous thrombi, which form under low shear conditions, are predominantly composed of fibrin and red cells, while arterial thrombi form under high shear conditions and are composed primarily of platelet aggregates held together by fibrin strands. Several successful strategies targeting specific steps in coagulation and platelet function or interaction have been developed to prevent or treat atherothrombotic disorders. Intense research is currently underway in an effort to develop more safe and effective compounds, such that novel antithrombotics are emerging to target specific steps in the coagulation cascade, as well as in pathways of platelet adhesion, activation and aggregation. This review will focus on the recent advances in research in this fast-evolving field.
