Correct answer: D — Restart apixaban within several days after confirming sustained ulcer hemostasis

The best answer is “Restart apixaban within several days after confirming sustained ulcer hemostasis”. Resuming anticoagulation after successful control of a reversible GI bleed generally lowers thromboembolism and mortality; timing is individualized to bleeding stability and stroke risk rather than fixed mechanically. Aspirin, prophylactic heparin, DAPT and an IVC filter do not provide equivalent AF stroke prevention.
