Key result
Anticoagulant therapy is linked to lower ischemic stroke mortality and declining stroke deaths in AFib.
Why the study?
Temporal changes in mortality rates and factors influencing ischemic stroke mortality among patients with AF remained to be evaluated.
Does anticoagulation therapy reduce ischemic stroke mortality in patients with atrial fibrillation over time?
Does anticoagulation therapy reduce ischemic stroke mortality in patients with atrial fibrillation over time?
Over a 40-year observation period, ischemic stroke mortality in patients with atrial fibrillation significantly decreased, likely driven by the increased use of anticoagulation therapy.
Anticoagulation may contribute to declining AF stroke mortality; leaves open causal confirmation in randomized trials.

Nakajima et al. (2023) studied this question. Anticoagulant therapy was associated with a lower risk of ischemic stroke mortality, contributing to a temporal decline in stroke deaths among patients with atrial fibrillation.
