WebAug 22, 2024 · Patients with proven pulmonary thrombosis are commonly treated with unfractionated heparin (UFH). Typically, it seemed that very high dosages of UFH were necessary to achieve therapeutic values of aPTT and anti-Xa levels in COVID-19 patients. WebUnfractionated heparin (UFH) binds t o anti-thrombin III (AT-III), which enhances antithr ombin's inhibition of several coagulation factors – especially factor Xa and factor IIa (thrombin). Low Molecular-Weight Heparin (LMWH) is a heter ogeneous collection of heparin molecules with a lower average molecular weight
