Monitoring unfractionated heparin (UFH) to ensure effective anticoagulation may be performed using anti-factor Xa activity (anti-Xa) instead of the activated partial thromboplastin time. However, in patients who have been treated with oral factor Xa (FXa) inhibitors (apixaban, rivaroxaban, and edoxaban) while switching to UFH therapy, there is a risk that these oral anti-FXa drugs could interfere with UFH calibrated anti-Xa monitoring. This may lead to inappropriate anticoagulation management.

Background: The management of recurrent venous thromboembolism (VTE) despite anticoagulant treatment in patients with cancer is uncertain. To address this, we used data from the Hokusai VTE Cancer trial, which compared edoxaban with dalteparin to treat cancer-associated VTE.
Methods: In this post-hoc analysis, we characterized and evaluated anticoagulant treatment strategies during and after on-treatment recurrent VTE, including the type and dose of anticoagulant.
Readily available and rapid turn-around, bedside assays to measure the effect of the direct oral anticoagulants (DOACs) are not available. This study evaluates a point-of-care (PoC) coagulometer to assess the anticoagulant effects of the DOACs and low molecular weight heparin. Studies were done in fresh spiked blood from healthy volunteers.

Background: Randomized clinical trials demonstrated similar efficacy and improved safety of direct oral anticoagulants versus warfarin in patients with atrial fibrillation (AF). Long-term data in routine clinical practice are needed.
Hypothesis: Patients with AF receiving edoxaban at baseline continue to have low annualized effectiveness and safety event rates in the second year of follow-up, with regional variations observed.

Background: The combination of antiplatelet and antithrombotic drugs increases the risk of bleeding in patients with atrial fibrillation after coronary drug-eluting stent (DES) implantation. However, the appropriateness of direct-acting oral anticoagulant (DOAC) monotherapy at the time of stent implantation remains uncertain. The objective of this study was to evaluate the safety and efficacy of DOAC monotherapy, specifically using factor Xa inhibitors such as edoxaban, in a low-density lipoprotein receptor knockout (LDL-R) miniature pig model of human-like unstable coronary plaques compared to conventional dual-antiplatelet therapy (DAPT).
