Article Synopsis
  • The management of carotid artery disease has predominantly relied on the degree of stenosis, but new research indicates that features like intraplaque hemorrhage can provide better diagnostic and treatment insights.
  • Current guidelines often overlook less than 50% stenosis cases, which can lead to misdiagnosis and inadequate treatments for potential stroke causes, leaving many patients untreated.
  • There is a push to reclassify certain strokes as symptomatic nonstenotic carotid disease when high-risk plaque features are present, and this review discusses historical practices, modern biomarkers of plaque vulnerability, imaging tools, and recent studies on this emerging classification.

Background: People with factor XI deficiency have lower rates of ischaemic stroke than the general population and infrequent spontaneous bleeding, suggesting that factor XI has a more important role in thrombosis than in haemostasis. Milvexian, an oral small-molecule inhibitor of activated factor XI, added to standard antiplatelet therapy, might reduce the risk of non-cardioembolic ischaemic stroke without increasing the risk of bleeding. We aimed to estimate the dose-response of milvexian for recurrent ischaemic cerebral events and major bleeding in patients with recent ischaemic stroke or transient ischaemic attack (TIA).

In 1981, the dismal outcomes of patients with basilar artery occlusion (BAO) inspired the first reports of intra-arterial thrombolytic treatment in BAO. These reports were among the first to conceptualize that opening an artery could help patients with large vessel occlusion stroke. Whereas multiple anterior circulation LVO trials demonstrated the efficacy of endovascular therapy starting in 2014, proof of benefit for BAO was lacking until 2022.

Background: Individuals with ischemic stroke or transient ischemic attack (TIA) have a high early risk of ischemic stroke despite dual antiplatelet therapy. The risk of ischemic stroke, and associated disability, represents a significant unmet clinical need. Genetic variants resulting in reduced factor XI levels are associated with reduced risk for ischemic stroke but are not associated with increased intracranial bleeding.

Objective: To measure the global impact of COVID-19 pandemic on volumes of IV thrombolysis (IVT), IVT transfers, and stroke hospitalizations over 4 months at the height of the pandemic (March 1 to June 30, 2020) compared with 2 control 4-month periods.

Methods: We conducted a cross-sectional, observational, retrospective study across 6 continents, 70 countries, and 457 stroke centers. Diagnoses were identified by their ICD-10 codes or classifications in stroke databases.
