Beijing United Family Hospital (BJU), the first UFH
hospital, commenced operations in 1997, and is still the only facility of its kind in Beijing.
* Peripartum management should include a scheduled de-escalation of long-acting anticoagulant drugs immediately before delivery, with short-term bridging using intravenous UFH
During the procedure of PCI, intravenous unfractionated heparin (UFH
) is mainly used as the standard anticoagulant in the catheterization laboratory, needing dose adjustment for activated clotting time (ACT)., Most domestic centers with interventional cardiology facilities would choose classical UFH
In hemorrhagic stroke, both UFH
and LMWH yielded the same results and thus were effective in preventing PE.
On the other hand, LMWHs, such as enoxaparin have been shown to be as safe and effective as intravenous UFH
With the competition between the chromogenic substrate and the anticoagulant of interest with anti-factor Xa activity (that is, any of the xabans, UFH
, LMWH, or fondaparinux), an inverse relationship is established between the optical density readout from the instrument and the exact anticoagulant level.
Systematic review and metaanalysis show that treatment with the combination of unfractionated heparin (UFH
) and aspirin could reduce the risk of pregnancy loss (relative risk, 0.46; 95% CI, 0.29 - 0.71) compared to aspirin alone, although the level of evidence was modest.
In certain instances, patients who have a high thromboembolic risk and are discontinuing warfarin therapy may require bridging therapy with a low-molecular-weight heparin (LMWH) or unfractionated heparin (UFH
* Warfarin, LMWH, fondaparinux and UFH
are safe to use in breastfeeding mothers.
Uncoordinated Frequency Hopping (UFH
)  has similarity to our work.
On the other hand, low molecular weight heparins (LMWHs) are smaller chains of UFH
that can be obtained by various chemical and enzymatic depolymerization processes, and their weight ranges from 2000 to 15000 kDa.
For example, in patients with cirrhosis, the efficacy of unfractionated heparin (UFH
) and LMWH may be significantly decreased (up to 40%) due to lower levels of antithrombin synthesis by the liver .
