Matteo Foschi: When Should We Restart Anticoagulation After a Breakthrough Ischemic Stroke?
Matteo Foschi, Neurologist at Azienda USL della Romagna, Affiliated Researcher at the Cochrane MS and Rare Diseases of the CNS Review Group, shared a post on LinkedIn about a recent article he and his colleagues co-authored, published in International Journal of Stroke, adding:
“When should we restart anticoagulation after a breakthrough ischemic stroke?
Patients who experience an ischemic stroke despite ongoing oral anticoagulation represent one of the most challenging and understudied populations in stroke medicine.
While recent randomized trials have informed DOAC timing after AF-related stroke, evidence for breakthrough stroke has remained limited.
I am happy to share our latest work from the ASPERA-R Study, published today on International Journal of Stroke:
A Target Trial Emulation framework with a cloning–censoring–weighting approach to compare early versus delayed DOAC resumption after breakthrough ischemic stroke.
Key findings
Early, severity-adapted DOAC initiation was associated with:
- 56% lower risk of new ischemic events at 90 days (HR 0.43)
- Lower moderate-to-severe bleeding risk (RR 0.10)
- 62% lower all-cause mortality (RR 0.38)
- 69% lower vascular mortality (RR 0.31)
- A consistently positive Net Early Benefit Score (NEBS) across all stroke severity categories.
Why these matters
Patients with breakthrough stroke face a particularly high risk of early recurrence.
Our findings suggest that early DOAC resumption may reduce recurrent ischemic events and mortality without increasing major bleeding, supporting a more proactive secondary prevention strategy in this high-risk population.
This study also demonstrates how target trial emulation can generate clinically meaningful evidence when randomized trials are lacking.
As always, my sincere thanks to all the ASPERA PIs and collaborators.”
