ABSTRACT
Heparin-induced thrombocytopenia (HIT) is a severe complication that can occur in patients exposed to any form or amount of heparin products. A fall in platelet counts and a hypercoagulable state characterize HIT. Patients who experience HIT may also develop thromboembolic complications that are associated with morbidity and mortality. This is a significant burden since heparin is widely used for treatment and prophylaxis of thromboembolism, line flushes, and heparin-coated catheters. This review will discuss the pathophysiology, diagnosis, and management of patients with HIT.
