Heparin induced thrombocytopenia
Abstract Background and Objectives Heparin is still a commonly used anticoagulant in prophylaxis and treatment of thromboembolic events. Heparin-induced thrombocytopenia (HIT) is a life-threating adverse drug reaction of heparin. The diagnosis of HIT is made based on two important criteria, firstly clinical evaluation and secondly laboratory testing. In this comprehensive review, the authors w...
متن کاملHeparin-induced thrombocytopenia and cardiac surgery.
Unfractionated heparin given during cardiopulmonary bypass is remarkably immunogenic, as 25% to 50% of postcardiac surgery patients develop heparin-dependent antibodies during the next 5 to 10 days. Sometimes, these antibodies strongly activate platelets and coagulation, thereby causing the prothrombotic disorder, heparin-induced thrombocytopenia. The risk of heparin-induced thrombocytopenia is...
متن کاملHeparin-induced thrombocytopenia in cardiac surgery and critically ill patients.
Thrombocytopenia as well as anti-platelet factor 4/heparin (PF4/H) antibodies are common in cardiac surgery patients and those treated in the intensive care unit. In contrast, heparin-induced thrombocytopenia (HIT) is uncommon in these populations (~1 % and ~0.5 %, respectively). A stepwise approach where testing for anti-PF4/H antibodies is performed only in patients with typical clinical symp...
متن کاملHeparin Induced Thrombocytopenia and Cardiac Surgery: A Comprehensive Review
Heparin induced thrombocytopenia presents as an underdiagnosed condition with life threatening thrombotic complications. The incidence in cardiac surgery patients is dependent on several factors and appeared to be greater in procedures that involve the use of intraaortic balloon pump. Clinical diagnosis is particularly challenging in cardiac surgery patients due to the natural occurrence of pos...
متن کاملHeparin-induced thrombocytopenia.
Heparin-induced thrombocytopenia (HIT) is an immune complication of heparin therapy caused by antibodies to complexes of platelet factor 4 (PF4) and heparin. Pathogenic antibodies to PF4/heparin bind and activate cellular FcγRIIA on platelets and monocytes to propagate a hypercoagulable state culminating in life-threatening thrombosis. It is now recognized that anti-PF4/heparin antibodies devel...
