Monogenic Causes in Familial Stroke Across Intracerebral Hemorrhage and Ischemic Stroke Subtypes Identified by Whole-Exome Sequencing
Cell Mol Neurobiol. 2022 Dec 29. doi: 10.1007/s10571-022-01315-3. Online ahead of print.ABSTRACTWhole exome sequencing (WES) has been used to detect rare causative variants in neurological diseases. However, the efficacy of WES in genetic diagnosis of clinically heterogeneous familial stroke remains inconclusive. We prospectively searched for disease-causing variants in unrelated probands with defined familial stroke by candidate gene/hotspot screening and/or WES, depending on stroke subtypes and neuroimaging features at a referral center. The clinical significance of each variant was determined according to the American C...

Stroke and bleeding risk assessment in atrial fibrillation: when, how, and why?
The objective of this review article is to provide an overview of stroke and bleeding risk assessment in AF. There would be particular emphasis on when, how, and why to use these risk stratification schemes, with a specific focus on the CHADS2 [congestive heart failure, hypertension, age, diabetes, stroke (doubled)], CHA2DS2-VASc [congestive heart failure or left ventricular dysfunction, hypertension, age ≥75 (doubled), diabetes, stroke (doubled)-vascular disease, age 65–74 and sex category (female)], and HAS-BLED [hypertension (i.e. uncontrolled blood pressure), abnormal renal/liver function, stroke, bleeding his...

Quality of Life Assessment in the Randomized PROTECT AF (Percutaneous Closure of the Left Atrial Appendage Versus Warfarin Therapy for Prevention of Stroke in Patients With Atrial Fibrillation) Trial of Patients at Risk for Stroke With Nonvalvular Atrial Fibrillation
ConclusionsPatients with nonvalvular AF at risk for stroke treated with left atrial appendage closure have favorable QOL changes at 12 months versus patients treated with warfarin.

A New Risk Scheme to Predict Ischemic Stroke and Other Thromboembolism in Atrial Fibrillation: The ATRIA Study Stroke Risk Score Arrhythmia and Electrophysiology
Conclusions The ATRIA stroke risk score performed better than existing risk scores, was validated successfully, and showed improvement in predicting severe events, which is of greatest concern. The ATRIA score should improve the antithrombotic decision for patients with AF and should provide a secure foundation for the addition of biomarkers in future prognostic models.

Stroke risk and suboptimal thromboprophylaxis in Chinese patients with atrial fibrillation: Would the novel oral anticoagulants have an impact?
Abstract: Background: The risk of stroke associated with atrial fibrillation (AF) is higher in Far Eastern population than in Western population, and warfarin use suboptimal. There is uncertainty whether the novel oral anticoagulants (NOACs) would have a major impact on stroke prevention in Far Eastern populations with AF.Objectives: We investigated current antithrombotic therapy use on stroke and bleeding risk, determinants of warfarin use and performed a modeling analysis of the net clinical benefit of the NOACs (apixaban, dabigatran) in a large cohort of Chinese patients with AF.Methods: We studied 1034 Chinese patients...

Validation of contemporary stroke and bleeding risk stratification scores in non-anticoagulated Chinese patients with atrial fibrillation
Abstract: Background: Risk stratification schemes assessing stroke and thromboembolism (stroke/TE) and bleeding relating to atrial fibrillation (AF) have largely been derived and validated in Western populations. We assessed risk factors that constitute scores for assessing stroke/TE (CHADS2, CHA2DS2-VASc) and bleeding (HAS-BLED), and the predictive value of these scores in a large cohort of Chinese patients with AF.Methods and results: We studied 1034 AF patients (27.1% female, median age 75; 85.6% non-anticoagulated) with mean follow-up of 1.9years. On multivariate analysis, vascular disease was independently associated ...

Pre-Operative Risk Factors of Bleeding and Stroke During Left Ventricular Assist Device Support An Analysis of More Than 900 HeartMate II Outpatients
ConclusionsThe risk of bleeding and thrombotic events during LVAD support differs by patient demographics, including sex, age, body mass index, and etiology of heart failure. Further studies should focus on the potential of tailored anticoagulation strategies in these subgroups.

Prediction of stroke in patients without atrial fibrillation using the CHADS2 and CHA2DS2-VASc scores: a justification for more widespread thromboprophylaxis?
The CHADS2 (congestive heart failure, hypertension, age ≥75 years, diabetes mellitus, previous stroke/transient ischaemic attack (TIA) (double)) and more recently, the CHA2DS2-VASc (congestive heart failure, hypertension, age ≥75 years (double score), diabetes mellitus, previous stroke/TIA (double score), vascular disease, age 65–74 years, sex category (female)) scores are validated clinical prediction tools commonly used to estimate the stroke risk in atrial fibrillation (AF) patients. More recently, the focus has been on initially identifying those patients at ‘low risk’ (ie, CHA2DS...

Gender and the risk of stroke in atrial fibrillation: impact of old and new anticoagulation regimens
Abstract Atrial fibrillation (AF) is the most common sustained arrhythmia. Thromboembolic events related to AF result in significant morbidity and mortality. An individual’s risk of thromboembolism in the setting of AF varies significantly based on clinical and demographic characteristics. The risk of stroke appears to be greater among women with AF than men. Warfarin provides sufficient protection against stroke, but does not eliminate gender differences in stroke rates. New oral anticoagulants demonstrated similar or superior efficacy compared to warfarin; however rates of stroke in women on new agents remain...

Standards and Barriers in Acute Stroke Therapy A Leap Forward in the Evolution of Endovascular Interventions for Stroke ∗
Whether interventional approaches to stroke neurology have lagged behind those aimed at heart attack—for reasons biological or practical—are topics for another day. However, the balance has changed. Tissue plasminogen activator (tPA) was first approved in the United States for intravenous administration to patients with acute stroke in 1996 (1), and a study for catheter-directed intra-arterial infusion of a thrombolytic agent for this indication was first published in 1998 (2). The first positive randomized controlled study using mechanical thrombectomy devices for stroke came from the Netherlands just last year (3), ...

Hsp70 protects from stroke in atrial fibrillation patients by preventing thrombosis without increased bleeding risk
Conclusions Hsp70 induction is a novel approach to delay thrombus formation with minimal bleeding risk, and is especially promising for treating AF patients and in other situations where there is also a major bleeding hazard.

Endothelial Cell-Derived von Willebrand Factor Is the Major Determinant That Mediates von Willebrand Factor-Dependent Acute Ischemic Stroke by Promoting Postischemic Thrombo-Inflammation.
CONCLUSIONS: Plt-VWF, either in presence or absence of ADAMTS13, partially contributes to VWF-dependent injury and postischemic thrombo-inflammation after stroke. EC-VWF is the major determinant that mediates VWF-dependent ischemic stroke by promoting postischemic thrombo-inflammation. PMID: 27444201 [PubMed - as supplied by publisher]
