I like > more than preferred. need to verify if UFH is appropriate vs DOACs. I feel like you can start with DOAC
per amboss: “UFH is preferred in patients with renal failure, inadequate subcutaneous absorption (i.e., morbid obesity), and those at a high risk of bleeding” and there is no mention of DOACs for initial parenteral anticoagulation for first 5-10 days, only for longterm (3-6 months)
