Overview
Heparin-induced thrombocytopenia is caused by a variety of factors. It is typically caused by unfractionated heparin (moreso than low-molecular weight heparin). Females are more likely to develop HIT. Patients undergoing cardiac surgery are more likely to develop HIT.
Causes
- HIT is always caused by exogenous heparin or heparinoid exposure.
- Duration of heparin treatment: long duration, up to 2 weeks is associated with the greatest risk.[1]
- The type of heparin involved: unfractionated heparin (UFH) puts patients at greater risk of HIT than low molecular weight heparin LMWH.[1]
