Correct answer: D — Unfractionated heparin IV with dose adjusted by aPTT

Unfractionated heparin is recommended as an antithrombin during early invasive treatment of NSTE-ACS. Fondaparinux alone is associated with catheter thrombosis unless combined with UFH during PCI; warfarin or full-dose DOACs are not used acutely.
