Efficacy and safety of edoxaban in comparison with dabigatran, rivaroxaban and apixaban for stroke prevention in atrial fibrillation. An indirect comparison analysis.
Abstract Large Phase 3 clinical trials for stroke prevention in atrial fibrillation (AF) have compared non-vitamin K antagonist oral anticoagulants (NOACs) against warfarin, with the edoxaban trial only recently reported. In the absence of head to head trials directly comparing these NOACs against each other, we compared the efficacy and safety of edoxaban to other agents by an indirect comparison analysis. We performed an indirect comparison analysis of edoxaban (2 dose strategies) against apixaban (1 dose), dabigatran etexilate (2 doses) and rivaroxaban (1 dose), for their relative efficacy and safety against ea...

Association of mean platelet volume and platelet count with the development and prognosis of ischemic and hemorrhagic stroke
ConclusionsIncreased MPV is an independent risk factor for both strokes. Elevated PLT count increases the risk for ischemic stroke, but decreases the risk for hemorrhagic stroke. However, neither MPV nor PLT count has significant association with the prognosis of either stroke.

Reasons for exclusion from intravenous thrombolysis in stroke patients admitted to the Stroke Unit
AbstractIntravenous (IV) thrombolysis is the treatment in ischemic stroke, but only the minority of patients receive this medication. The primary objective of this study was to explore the reasons associated with the decision not to offer IV thrombolysis to stroke patients admitted to the Stroke Unit (SU). We conducted a retrospective analysis based on data collected from 876 consecutive stroke patients admitted to the SU  <12  h of symptoms onset, treated or not with IV thrombolysis at the discretion of the treating neurologist. Of the 876 patients, 449 were thrombolysed and 427 non-thrombolysed. Stroke onset >4....

Serum 25-hydroxyvitamin D and the risk of stroke in Hong Kong Chinese.
In conclusion, a low vitamin D level is associated with increased risk of ischaemic stroke; however, whether high vitamin D level is also associated with increased risk of stroke requires further study. PMID: 27786341 [PubMed - as supplied by publisher]

Filaggrin loss-of-function mutations as risk factors for ischemic stroke in the general population.
CONCLUSION: In this study of 97,174 individuals from the Danish general population, FLG loss-of-function mutations were associated with increased ischemic stroke risk; however, residual confounding is a possibility.

Dynamic Changes of CHA2DS2-VASc Score and the Risk of Ischaemic Stroke in Asian Patients with Atrial Fibrillation: A Nationwide Cohort Study.
CONCLUSION:  In AF patients, stroke risk as assessed by the CHA2DS2-VASc score is dynamic and changes over time. Rates of ischaemic stroke increased when patients accumulated risk factors, and were re-classified into higher CHA2DS2-VASc score categories. Stroke risk assessment is needed at every patient contact, as accumulation of risk factors with increasing CHA2DS2-VASc score translates to greater stroke risks over time.

Vascular Proteomics Reveals Critical Roles of ADAMTS18 in Stroke Associated with Imbalanced Level of Von Willebrand Factor Versus ADAMTS13
Conclusion and Significance-Results of this first vascular proteomic study of Adamts18 KO mice establish a substantial new resource for investigation of how ADAMTS gene affects cellular phenotypes of stroke. These new findings contribute to inform novel prevention strategies and direct therapeutic development for stroke.DisclosuresNo relevant conflicts of interest to declare.

Effect of prothrombotic genotypes on the risk of venous thromboembolism in patients with and without ischemic stroke.The Troms Ø Study.
CONCLUSIONS: Prothrombotic genotypes increased the risk of VTE in stroke patients, and the risk increased with increasing number of risk alleles. This article is protected by copyright. All rights reserved. PMID: 30773804 [PubMed - as supplied by publisher]

Clopidogrel increases risk of pneumonia compared with aspirin in acute ischemic minor stroke patients
AbstractAntiplatelet agents may increase the risk of infections via suppressing platelet-mediated immune response. Here we assessed the contribution of clopidogrel versus aspirin to the development of pneumonia during an acute ischemic stroke admission. A retrospective cohort study was conducted of acute ischemic stroke patients who were admitted to our hospital from 2015 to 2018. Included patients received uninterrupted clopidogrel or aspirin therapy and did not take other antiplatelet agents throughout their stay. The interest outcome was development of pneumonia after stroke. Conditional logistic regression model after ...

Use of Non-vitamin K Antagonist Oral Anticoagulants for Stroke Prevention across the Stroke Spectrum: Progress and Prospects.
Abstract Multiple randomized controlled trials and many real-world evidence studies have consistently shown that non-vitamin K antagonist oral anticoagulants (NOACs) are preferable to vitamin K antagonists for thromboembolic stroke prevention in the majority of patients with atrial fibrillation (AF). However, their role in the management of patients with AF and comorbidities, as well as in other patient populations with a high risk of stroke, such as patients with prior embolic stroke of undetermined source (ESUS) and those with atherosclerosis, is less clear. There is now increasing evidence suggesting that NOACs...

Hemorrhagic Transformation and Stroke Recurrence in Children with Cardiac Disease Receiving Antithrombotic Therapy for Secondary Stroke Prevention
CONCLUSIONS: In spite of the 24% hemorrhagic transformation rate, antithrombotic therapy has a positive risk-balance in certain cardioembolic stroke subgroups, particularly in those with single-ventricle physiology, when accounting for stroke volume.PMID:34152075 | DOI:10.1111/jth.15428

Red cell distribution width is associated with future risk of incident stroke. The Tromsø Study.
Abstract Red cell distribution width (RDW), a measure of the variability in size of the circulating erythrocytes, is associated with cardiovascular morbidity and mortality. We aimed to investigate whether RDW was associated with incident stroke and case fatality in subjects recruited from the general population. Baseline characteristics were obtained from 25,992 subjects participating in the fourth survey of the Tromsø Study, conducted in 1994/95. Incident stroke was registered from inclusion until December 31, 2010. Cox regression models were used to calculate hazard ratios (HR) with 95 % confidence intervals ...

Low ADAMTS13 activity is associated with an increased risk of ischemic stroke
ADAMTS13 (a disintegrin and metalloproteinase with a thrombospondin motif repeats 13) has antithrombotic properties because it cleaves von Willebrand factor (VWF) in smaller, less active multimers. The aim of our study was to investigate prospectively the association between ADAMTS13 activity and ischemic stroke. We included 5941 individuals ≥55 years without a history of stroke or transient ischemic attack (TIA) of the Rotterdam Study, a population-based cohort study. ADAMTS13 activity was measured at inclusion with the FRETS-VWF73 assay and VWF antigen (VWF:Ag) levels by enzyme-linked immunosorbent assay. We assessed ...
