Ischemic heart disease among South Asians with ischaemic stroke in three countries across two continents: the BRAINS study.

Background: Ischaemic heart disease (IHD) and cardiometabolic risk factors have been extensively investigated in those of European descent, yet they are more common among South Asians who make up around 20% of the world's population. We explored the differences in IHD and cumulative metabolic profile in South Asians with stroke living in the UK, India and Qatar, compared with white British stroke patients.

Methods: The study included first-ever ischemic stroke white British patients and South Asians living in UK, India and Qatar from the ongoing large Bio-Repository of DNA in Stroke (BRAINS) international hospital-based stroke study.

Derivation of a CT Angiography-Based Arch Atherosclerosis Grading in Cryptogenic Ischemic Stroke.

Background And Objectives: We aimed to develop a novel computed tomography angiography (CTA)-based grading system to quantify the severity of aortic arch disease and compare the detection of aortic arch atherosclerosis (AAAthero) on routinely acquired arch-to-vertex CTA against transesophageal echocardiogram (TEE) among patients with cryptogenic ischemic stroke.

Methods: A systematic literature review was conducted to develop a computed tomography (CT)-based AAAthero grading system. CTA was compared against TEE for detecting AAAthero.

Net Benefit of Early Anticoagulation for Stroke With Atrial Fibrillation: Post Hoc Analysis of the ELAN Randomized Clinical Trial.

Importance: The net clinical effect of early vs later direct oral anticoagulant (DOAC) initiation after atrial fibrillation-associated ischemic stroke is unclear.

Objective: To investigate whether early DOAC treatment is associated with a net clinical benefit (NCB).

Design, Setting, And Participants: This was a post hoc analysis of the Early Versus Late Initiation of Direct Oral Anticoagulants in Post-Ischaemic Stroke Patients With Atrial Fibrillation (ELAN) open-label randomized clinical trial conducted across 103 sites in 15 countries in Europe, the Middle East, and Asia between November 6, 2017, and September 12, 2022, with a 90-day follow-up.

Clinical, Imaging, and Atrial Cardiopathy Markers in Ischemic Stroke Subtypes - Clues to a Cardioembolic Source.

Background And Objectives: Cryptogenic strokes account for 20%-25% of all ischemic strokes. Although atrial cardiopathy markers are more prevalent in the cryptogenic embolic stroke of undetermined source (ESUS) subgroup than in the nonembolic stroke subgroup, the utility of individual parameters in predicting cardioembolic sources needs to be studied further. We studied the clinical, imaging, and atrial cardiopathy markers in three ischemic stroke subtypes - large artery atherosclerosis (LAA), cardioembolism (CE), and cryptogenic ESUS - and their role in predicting the source of CE.
