Key result
Advanced vascular imaging and systematic prevention show promise for stroke reduction in AF and stenosis.
Why the study?
Critical gaps remain in evidence guiding management of symptomatic carotid and intracranial stenosis and quality of anticoagulation care in atrial fibrillation patients despite decades of stroke prevention trials.
This review highlights the need for contemporary prospective data, integration of advanced vascular imaging biomarkers, and systematic improvements in preventative therapies to optimize stroke prevention in patients with carotid/intracranial stenosis and atrial fibrillation.

“I am extremely honored to receive this award and for the immense support of the American Stroke Association in advancing stroke prevention education and treatment. Together, we continue to move the needle in delivering recommendations and resources that truly make a difference in patients and their families nationally.”
“Dr. Chaturvedi is an outstanding leader and physician-scientist who is deeply committed to helping patients achieve the best outcomes possible through every stage of stroke care. He is a pillar in our Comprehensive Stroke Center and this honor is a reflection of his tremendous passion for the field and the research needed to drive positive outcomes.”
Persistent gaps in stroke prevention evidence warrant caution in stenosis and AF management; leaves open optimal strategies pending further trials.
Despite decades of clinical trial activity in stroke prevention, critical gaps remain in the evidence base guiding management of symptomatic carotid and intracranial stenosis and the quality of anticoagulation care delivered to patients with atrial fibrillation (AF). This article synthesizes recent evidence and ongoing research efforts addressing 2 enduring challenges: demonstrating the value of intensive medical therapy relative to interventional approaches and improving the quality of stroke prevention care in AF. Previous trials focused on intracranial stenosis established that aggressive, protocol-driven medical management substantially reduces recurrent vascular events. In the realm of carotid stenosis, landmark trials conducted >3 decades ago no longer reflect modern pharmacological capabilities. Emerging evidence from plaque imaging, particularly intraplaque hemorrhage on magnetic resonance imaging, suggests that stenosis severity alone is an insufficient determinant of treatment strategy. Simultaneously, strokes related to AF continue to rise in the United States, driven by demographic aging, and large vessel occlusion strokes attributable to undertreated AF represent a preventable burden on the health system. Patient-centered, precision stroke prevention requires contemporary prospective data, integration of advanced vascular imaging biomarkers, and systematic improvements in preventative therapies for patients with AF. Targeting these areas holds promise for improving stroke prevention in the coming decades.
