Overview
Heparin-induced thrombocytopenia is diagnosed when the platelet count falls by > 50% typically after 5-10 days of heparin therapy. The causes of the condition depends on type of heparin (unfractionated heparin > low molecular weight heparin), duration of therapy, females and type of patients (commoner in surgical patients that require large amount of heparin)
Causes
- Duration of heparin treatment; long duration, up to 2 weeks is associated with the greatest risk.
- The type of heparin involved; unfractionated heparinUFH has a greater risk than low molecular weight heparin LMWH.
- The type of patient; surgical patients are at higher risk than medical; cardiac surgical patients have the highest risk of all.
- Females have a higher risk.
