Background & Purpose: Non-stenotic (< 50%) carotid plaques are increasingly recognized as a potential mechanism for ischemic stroke. We assessed the prevalence of such plaques in patients with low-risk neurologic events and evidence of DWI (Diffusion Weighted Imaging)-positive ischemia.

Methods: This is a post-hoc exploratory analysis from the DOUBT study, a prospective, observational, multicenter study of patients with low-risk transient or persistent minor focal neurological symptoms.

Brain ischemia is a major cause of neurological dysfunction and mortality worldwide. It occurs not only acutely, such as in acute ischemic stroke (AIS), but also in chronic conditions like cerebral small vessel disease (cSVD). Any other conditions resulting in brain hypoperfusion can also lead to ischemia.

Diagnosis of Atrial Fibrillation as the Source of Cryptogenic Retrieved Clots by a Novel Thrombin Secretion Assay.

Heart Rhythm

December 2024

Department of Neurology, The Chaim Sheba Medical Center, Ramat Gan 5266202, Israel; Department of Neurology and Neurosurgery, Faculty of Medicine and Health Sciences, Tel Aviv University, Tel Aviv 6997801, Israel; The TELEM Rubin Excellence in Biomedical Research Program, The Chaim Sheba Medical Center, Ramat Gan, Israel. Electronic address:

Background: Secondary prevention of acute ischemic stroke depends on identifying the source of cryptogenic clots. We previously reported that secreted thrombin activity from endovascularly retrieved clots is significantly different in atrial fibrillation (AF) versus atherosclerosis (AS) related, probably due to the in-vivo biology of the clots.

Objectives: To validate and optimize thrombin secretion for clot source diagnosis.

Background: It is unclear whether the extent of neuroaxonal damage, as measured by circulating levels of neurofilament light chain (NfL), would modify the effects of early antihypertensive therapy on cognitive performance following stroke. This study aimed to investigate the effects of early blood pressure reduction on the risk of post-stroke cognitive impairment (PSCI) among patients with different plasma NfL levels.

Methods: A total of 622 eligible patients from a pre-planned ancillary study of CATIS (China Antihypertensive Trial in Acute Ischemic Stroke) were included in this study.

Background: Decisions about stroke prevention strategies in atrial fibrillation (AF) typically balance thromboembolism reduction against increased bleeding from oral anticoagulation therapy (OAC). When determining eligibility for OAC, guidelines recommend calculation of thromboembolic event rates using a validated score such as CHA2DS2-VASc. In contrast, routine calculation of bleeding scores is not recommended, in part because many patient factors associated with an increased risk of bleeding are associated with an even larger increased risk of ischemic stroke.

Aim: Due to the absence of validated bleeding risk tools in cancer patients undergoing percutaneous coronary intervention (PCI), we aimed to validate an adapted version of the Academic Research Consortium (ARC) High Bleeding Risk (HBR) criteria.

Methods: Consecutive patients with active or remission cancer undergoing PCI between 2012 and 2022 at Mount Sinai Hospital (New York, USA) were included. Patients were considered at HBR if they met at least one of the major ARC-HBR criteria, other than cancer, or two minor criteria.

Am J Hypertens

December 2024

Department of Neurosurgery, Beijing Hospital, National Center of Gerontology, Institute of Geriatric Medicine, Chinese Academy of Medical Sciences, Beijing, China.

Intravenous thrombolysis and mechanical thrombectomy reduce morbidity and improve functional outcome in ischemic stroke. However, acute recanalization therapies may increase the risk of symptomatic intracranial hemorrhage due to its effects on the brain tissue. An increasing proportion of patients with ischemic stroke are using direct oral anticoagulants (DOACs).

Purpose: Patients with contralateral carotid artery occlusion (CCO) represent a subgroup of patients at risk for revascularization procedures. The choice of appropriate revascularization procedure (carotid endarterectomy (CEA) or carotid artery stenting (CAS)) in these patients is controversial. The aim of this study is to share the results of clinical and radiological follow-up after CAS in these patients and to contribute to the literature by evaluating the efficacy and safety of stenting.

Purpose: Embolic stroke of unidentified source (ESUS) represents 10-25% of all ischemic strokes. Our goal was to determine whether ESUS could be reclassified to cardioembolic (CE) or large-artery atherosclerosis (LAA) with machine learning (ML) using conventional clinical data.

Methods: We retrospectively collected conventional clinical features, including patient, imaging (MRI, CT/CTA), cardiac, and serum data from established cases of CE and LAA stroke, and factors with p < 0.

Department of Medicine, University of Helsinki, Helsinki, Finland; Department of Internal Medicine, Jorvi Hospital, Espoo, Finland; Department of Internal Medicine, Helsinki University Hospital, Helsinki, Finland.

Background: Atrial fibrillation (AF) is a major risk factor for ischemic stroke (IS), but whether the magnitude of this risk has changed over time is unknown.

Objectives: This study sought to investigate temporal trends in IS rates in patients with incident AF before oral anticoagulant agent (OAC) therapy.

Methods: The nationwide FinACAF (Finnish Anticoagulation in Atrial Fibrillation) study covers patients with AF at all levels of care in Finland from 2007 to 2018.

Background: Prior analyses have suggested that a smaller left ventricular end-diastolic diameter (LVEDD) is associated with reduced survival following HeartMate 3 left ventricular assist device implantation.

Objectives: In this trial-based comprehensive analysis, the authors sought to examine clinical characteristics and association with the outcome of this specific relationship.

Methods: The authors analyzed the presence of LVEDD <55 mm among 1,921 analyzable HeartMate 3 patients within the MOMENTUM 3 (Multicenter Study of MagLev Technology in Patients Undergoing Mechanical Circulatory Support Therapy With HeartMate 3) trial portfolio, on endpoints of overall survival and adverse events at 2 years.

The blood-brain barrier (BBB) is the most central component of the neurovascular unit (NVU) and is crucial for the maintenance of the internal environment of the central nervous system and the regulation of homeostasis. A multitude of neuroprotective agents have been developed to exert neuroprotective effects and improve the prognosis of patients with ischemic stroke. These agents have been designed to maintain integrity and promote BBB repair.

Recurrent strokes after transcatheter aortic valve replacement in an elderly patient with severe bicuspid aortic valve stenosis: a case report.

BMC Cardiovasc Disord

December 2024

Department of Cardiology, Beijing Hospital, National Center of Gerontology, Institute of Geriatric Medicine, Chinese Academy of Medical Sciences, Beijing, 100730, China.

Background: Transcatheter aortic valve replacement (TAVR) has evolved from a novel technology to an established therapy for high-risk patients with symptomatic severe aortic valve stenosis (AS). Recently, its use has also been extended to low-risk patients, resulting in its increasing utilization in patients with bicuspid aortic valve (BAV). But as a serious post-TAVR complication, ischemic stroke was associated with a nearly 6-fold increased 30-day mortality.

Ischemic strokes pose serious risks to human health. We aimed to elucidate the function of NOD-like receptor X1 (NLRX1) in a rat middle cerebral artery occlusion (MCAO)-induced cerebral ischemia/reperfusion injury (CIRI) model and in an oxygen-glucose deprivation/reperfusion (OGD/R)-treated human microglial cell line (HMC3) model. Following NLRX1 upregulation, infarct volumes were measured with 2,3,5-triphenyltetrazolium chloride staining and pathological examination was conducted with hematoxylin-eosin staining.

Background: In children and adults with sickle-cell disease (SCD), acute ischemic stroke (AIS) associated with a vaso-occlusive crisis is a leading cause of physical and cognitive disability and death. However, neurological guidelines for acute management of AIS fail to directly address this issue. We here report a case of a man with severe cerebrovascular complications and illustrate the current evidence on the management of SCD-related AIS.
