Heparin-induced thrombocytopenia: present and future

Article

Abstract

Heparin-induced thrombocytopenia (HIT) is a prothrombotic and potentially devastating complication of heparin therapy due to formation of platelet-activating antibodies against complexes of platelet factor 4 and heparin. Over the last several decades, great advances in our understanding of HIT have elevated a once enigmatic syndrome, the mere existence of which was doubted by the medical community, to a well-characterized disorder. Nevertheless, critical questions remain unanswered. The objective of this review is to examine our current understanding of the epidemiology, pathophysiology, diagnosis, and management of HIT and to highlight areas of future inquiry.
