Heparin-induced thrombocytopenia (HIT) is the development of thrombocytopenia (a low platelet count), due to the administration of various forms of heparin, an anticoagulant. HIT predisposes to thrombosis (the abnormal formation of blood clots inside a blood vessel ).
If the patient is 'low risk' using the CHA 2 DS 2-VASc score (that is, 0 in males or 1 in females), no anticoagulant therapy is recommended. In males with 1 stroke risk factor (that is, a CHA 2 DS 2-VASc score=1), antithrombotic therapy with OAC may be considered, and people's values and preferences should be considered. [24]
[3] The prevalence of antithrombin deficiency is estimated at ~0.02 to 0.2% of the general population, and 1-5% of patients with venous thromboembolism. [ 6 ] There is an elevated risk of thrombosis, whereby 50% patients with AT deficiency were found to have venous thromboembolism by age 50.
Argatroban (as well as the hirudins) is used for heparin-induced thrombocytopenia, a relatively infrequent yet serious complication of heparin treatment that requires anticoagulation (as it increases both arterial and venous thrombosis risk) but not with the causative agent, heparin. [1]
The coagulation cascade.. Warfarin necrosis usually occurs three to five days after drug therapy is begun, and a high initial dose increases the risk of its development. [3]: 122 Warfarin-induced necrosis can develop both at sites of local injection and - when infused intravenously - in a widespread pattern.
The use of LMWHs should be avoided in patients with known allergies to LMWHs, heparin, sulfites or benzyl alcohol, in patients with active major bleeding, or in patients with a history of heparin-induced low blood platelet count (also known as heparin-induced thrombocytopenia or HIT). High treatment doses are contraindicated in acute bleeding ...
“At some point the markets are going to demand a premium to accept the risk of financing” such increased borrowing, he said. Later Wednesday, the Fed will release minutes from its December meeting and that may shed more light on what policymakers were thinking about inflation and the potential impact of tariffs. 01/08/2025 13:12 -0500
A significant reduction in the rate of cardiac mortality in patients treated with bivalirudin monotherapy versus UFH plus a GP IIb/IIIa inhibitor was maintained at 1 year in the HORIZONS AMI trial (2.1% vs. 3.8%)The incidence of stent thrombosis at 1 year was also similar between the 2 treatment groups (3.5% in the Angiomax group vs. 3.2% in ...
