Objective Post-stroke cognitive impairment often afflicts stroke survivors and is a major obstacle both for cognitive and physical rehabilitation. Stroke risk scores ["Congestive heart failure, Hypertension, Age ≥75 years, Diabetes mellitus, Stroke" (CHADS2) and "CHADS2 + creatinine clearance <60 mL/min" (R2CHADS2)] are used to assess the future risk of cardioembolic stroke in patients with atrial fibrillation (AF). However, congestive heart failure, hypertension, aging, diabetes mellitus, stroke, and renal dysfunction are also risk factors for cognitive impairment...

AIMS: The J-STARS study examined whether pravastatin (10 mg/day) reduces recurrence of stroke in non-cardioembolic ischemic stroke patients who were enrolled within 1 month to 3 years after initial stroke events (ClinicalTrials.gov, NCT00221104). The main results showed that the frequency of atherothrombotic stroke was low in pravastatin-treated patients, although no effect of pravastatin was found for the other stroke subtypes. We evaluated differences of early (within 6 months) or late (after 6 months) pravastatin treatment benefits on the incidence of stroke or transient ischemic attack (TIA), as well as atherothrombotic stroke and the other subtypes...

OBJECTIVE: Prolonged ECG monitoring after stroke frequently reveals short paroxysmal atrial fibrillation (pAF) and supraventricular (SV) runs. The minimal duration of atrial fibrillation (AF) required to induce cardioembolism, the relevance of SV runs, and whether short pAF results from cerebral damage itself are currently being debated. We aimed to study the relevance of SV runs and short pAF detected by prolonged Holter ECG after cerebral ischemia during long-term follow-up. METHODS: Analysis is from the prospective Find-AF trial (ISRCTN46104198)...

Background and purpose Previous studies have suggested that atrial septal aneurysm is a potential risk factor for cerebral embolism. However, the association between the level of atrial septal protrusion and cerebral embolism is still unclear. The purpose of the present study was to assess the association between the maximal distance of atrial septal protrusion and cryptogenic stroke. Methods A total of 588 consecutive acute ischemic stroke patients (70 ± 11 (mean ± SD) years, 401 men) who underwent transesophageal echocardiography were enrolled...

BACKGROUND AND PURPOSE: There remains uncertainty as whether newly diagnosed atrial fibrillation (AF) after ischemic stroke reflects underlying heart disease and represents an increased risk of cardioembolic stroke, or whether it is triggered by neurogenic mechanisms. We aimed to determine whether cardiovascular comorbidities in patients with new AF after ischemic stroke differ from patients with previous known AF or without AF. METHODS: This French longitudinal cohort study was based on the database covering hospital care from 2009 to 2012 for the entire population...

Recently, the clinical entity embolic stroke of undetermined source (ESUS) has been defined for patients with ischemic strokes, where neither a cardioembolic nor a non-cardiac source can be detected. These patients may suffer from asymptomatic atrial fibrillation (AF), terminating spontaneously and thus eluding detection. Implantable loop recorders (ILR) with automatic AF detection algorithms can detect short-lasting, subclinical AF. The aim of this study was to prospectively assess and predict AF detection in patients with ESUS using ILR with daily remote interrogation...

AIM: While autonomic imbalance during defecation/micturition can cause hemodynamic instability, stroke occurring in the toilet has rarely been investigated. The objective of the present study was to clarify the frequency and clinical characteristics of toilet-related stroke. METHODS: Clinical data prospectively acquired between January 2011 and December 2015 on 1939 patients with acute stroke (1224 cerebral infarctions [CI], 505 intracerebral hemorrhages [ICH] and 210 subarachnoid hemorrhages [SAH]) were reviewed to identify patients with a toilet-related stroke...

BACKGROUND: Cardioembolism is considered a major pathophysiological mechanism in patients with ischemic stroke (IS) and Chagas disease (CD). However, a previous study reported that other stroke subtypes are present in more than 40% of CD patients according to the TOAST classification. Therefore, the aim of our study was to evaluate the etiologic classification of stroke in patients with CD using the Causative Classification System (CCS), the ASCOD, and the TOAST classifications in a prospective cohort of patients...

Studies have demonstrated that matrix metalloproteinase-3 (MMP-3) is involved in the development and progression of atherosclerosis. However, there is no information available on the association of MMP-3 5A/6A polymorphism with recurrent ischemic stroke (IS) in different IS subtypes. We investigated the potential associations between MMP-3 serum level and -1171 5A/6A polymorphism and the recurrence of IS in a Chinese population. Consecutive acute first-ever IS patients were enrolled between August 2008 and October 2013...

Neutrophil extracellular traps (NETs) are networks of DNA, histones, and proteolytic enzymes produced by activated neutrophils through different mechanisms. NET formation is promoted by activated platelets and can in turn activate platelets, thus favoring thrombotic processes. NETs have been detected in venous and arterial thrombosis, but data in stroke are scarce. The aim of this study was to evaluate NETs in the plasma of patients with acute ischemic stroke and their potential association with baseline clinical characteristics, stroke severity, and one-year clinical outcomes...

BACKGROUND AND PURPOSE: The associations of individual long-chain n-3 polyunsaturated fatty acids with incident ischemic stroke and its main subtypes are not well established. We aimed to investigate prospectively the relationship of circulating eicosapentaenoic acid, docosapentaenoic acid (DPA), and docosahexaenoic acid (DHA) with risk of total ischemic, atherothrombotic, and cardioembolic stroke. METHODS: We measured circulating phospholipid fatty acids at baseline in 3 separate US cohorts: CHS (Cardiovascular Health Study), NHS (Nurses' Health Study), and HPFS (Health Professionals Follow-Up Study)...

OBJECTIVES: Thioredoxin (Trx) is one of significant antioxidative molecules to diminish oxidative stress. Current evidence suggests that Trx is a potent antioxidant with cytoprotective functions. The aim of our study was to investigate specifically the association between serum Trx levels and acute ischemic stroke (AIS) patients. METHODS: 198 AIS patients and 75 controls were enrolled to the study. Serum Trx levels were measured using an enzyme-linked immunosorbent assay (ELISA)...

Papillary fibroelastomas (PFEs) are rare and benign cardiac tumors which usually are localized on the valves (mostly on the aortic valve), though they may originate also from the ventricles or atrial walls. Whilst, in the large majority of cases, these lesions are asymptomatic they may cause serious complications such as thromboembolic events, or more rarely valvular dysfunctions. Surgical excision is necessary for a symptomatic lesion. The management of asymptomatic lesions is not defined. Herein are reported the details of a miniseries of six cases operated on at the authors' institution between 2005 and 2015...

BACKGROUND: Closure of the left atrial appendage (LAA) to prevent cardioembolic events is an alternative therapy to oral anticoagulation in patients with non-valvular atrial fibrillation. The LAA is an important source of natriuretic peptides and its exclusion from the circulation may alter the blood level of these hormones, thereby influencing their diagnostic value and clinical effects. METHODS: We aimed to prospectively assess potential changes in mid-regional pro A-type natriuretic peptide (MR-proANP) and N-terminal pro B-type natriuretic peptide (NT-proBNP) levels six weeks and six months after interventional LAA closure using the Watchman device...

BACKGROUND: Annotation and Image Markup on ClearCanvas Enriched Stroke-phenotyping Software (ACCESS) is a novel stand-alone computer software application that allows the creation of simple standardized annotations for reporting brain images of all stroke types. We developed the ACCESS application and determined its inter-rater and intra-rater reliability in the Stroke Investigative Research and Educational Network (SIREN) study to assess its suitability for multicenter studies. METHODS: One hundred randomly selected stroke imaging reports from 5 SIREN sites were re-evaluated by 4 trained independent raters to determine the inter-rater reliability of the ACCESS (version 12...
