Effect of Right Insular Involvement on Death and Functional Outcome After Acute Ischemic Stroke in the IST-3 Trial (Third International Stroke Trial) Clinical Sciences
Conclusions—We found an association between right insular involvement and higher odds of death and worse functional outcome. The difference between right- and left-sided insular lesions on outcomes seemed to be most evident for mild/moderate strokes.Clinical Trial Registration—URL: http://www.isrctn.com. Unique identifier: ISRCTN25765518.

Special MRI scan could identify stroke risk in people with atrial fibrillation
Atrial fibrillation is a heart rhythm disorder that affects millions of people. It can make you feel lousy. Even worse, it can cause potentially disabling or deadly strokes. A special MRI scan may — I stress the “may” — help identify people with atrial fibrillation who are at high risk of having a stroke. This could help many people with this condition to avoid taking warfarin or other clot-preventing medications for life. A normal heartbeat starts in a cluster of cells called the pacemaker. It sits in the heart’s upper right chamber (the right atrium). These cells generate a pulse of electricity that...

Preadmission Oral Anticoagulant Treatment and Clinical Outcome Among Patients Hospitalized With Acute Stroke and Atrial Fibrillation: A Nationwide Study Clinical Sciences
Conclusions— Only a minority of hospitalized patients with acute stroke with atrial fibrillation received OAT at the time of stroke. Preadmission OAT was associated with less severe stroke and lower 30-day mortality rate in a propensity score–matched analysis.

Stroke Risk Factors, Subtypes, and 30-Day Case Fatality in Abuja, Nigeria (P1.121)
CONCLUSIONS: Although hypertension, obesity, diabetes mellitus, and atrial fibrillation were important stroke risk factors, in many patients, these were detected only after a stroke. While the commonest stroke subtype was cerebral infarction, observed in almost two-third of patients, SAH was associated with the highest case-fatality rate at 30 days of 44.4%. Larger population-based studies are planned.Study Supported by: nilDisclosure: Dr. Bwala has nothing to disclose.

Structural MRI markers of brain aging early after ischemic stroke
Conclusions: Brain structure is likely to be compromised before ischemic stroke by vascular risk factors. Smaller hippocampal and total brain volumes and increased WMH load represent proxies for underlying vascular brain injury.

Discrimination of Acute Ischemic Stroke from Nonischemic Vertigo in Patients Presenting with Only Imbalance
We examined 332 consecutive patients with an acute feeling of imbalance who showed no neurologic findings or responsible lesions on CT scan at the hyperacute phase. We examined their clinical backgrounds, physical findings, and laboratory examinations, with ischemic stroke diagnosed by later CT and/or magnetic resonance imaging (MRI). We identified 41 (12.3%) ischemic stroke patients. Atrial fibrillation (odds ratio 4.1; 95% confidence interval 1.4-11.5), white blood cell count (103/μL, 1.4; 1.2-1.6), head and/or neck pain (4.6; 2.1-10.3), first attack of imbalance feeling (3.3; 1.1-12.2), and dizziness (3.7; 1.7-8.3) wer...

Embolic Stroke of Undetermined Source (ESUS): A single center study from Argentina (P1.060)
CONCLUSIONS: Even with complete work-up, upon initial assessment more than one third of ischemic stroke patients met criteria for ESUS. After one year follow-up, it is possible to reclassify some of them, mostly as cardioembolic. More studies are needed to establish unidentified etiologies and the effect of longer follow-ups.

Atrial Fibrillation and Cognitive Decline-The Role of Subclinical Cerebral Infarcts: The Atherosclerosis Risk in Communities Study Clinical Sciences
Conclusions— The association of incident AF with cognitive decline in stroke-free individuals can be explained by the presence or development of SCIs, raising the possibility of anticoagulation as a strategy to prevent cognitive decline in AF.

Effective ADAPT Thrombectomy in a Patient with Acute Stroke due to Cardiac Papillary Elastofibroma: Histological Thrombus Confirmation
A 75-year-old man with hypertension and atrial fibrillation was admitted to our emergency room with right-sided hemiplegia and complete aphasia (National Institutes of Health Stroke Scale [NIHSS] score  = 18). A noncontrast computed tomography scan showed a slight hypodensity in the left insular region and a bright hyperdense sign in the M1 tract of the left middle cerebral artery (MCA). Angio-CT confirmed an occlusion of the M1 tract of the MCA. Magnetic resonance diffusion-weighted imaging/p erfusion-weighted imaging was obtained and revealed a mismatch in the left parietal cortical region.

Limb Shaking Transient Ischemic Attacks with Normal Neurovascular Ultrasound may Herald Cardioembolic Stroke: ACase Report
We describe a 74 year-old woman with abrupt left arm jerking and normal urgent computed tomography scan, electroencephalography (EEG) as well as carotid and transcranial ultrasound. Two days later she developed an overt ischemic stroke, with left mesencephalon and left cerebellar hemisphere lesions at brain magnetic resonance imaging and paroxysmal atrial fibrillation at Holter-EKG.

A Post-hoc Study of D-Amino Acid Oxidase in Blood as an Indicator of Post-stroke Dementia
In conclusion, our data support that plasma DAO levels were increased in PSD patients and correlated with brain WMH, independent of age, gender, hypertension, and renal function. Plasma DAO levels may therefore aid in PSD diagnosis. Introduction Stroke is a risk factor for both vascular dementia and Alzheimer's disease (1, 2). Functional recovery develops over the course of 26 weeks after a stroke (3), but the survivors are often left with disabilities. In addition to the sequelae of acute neuronal damage, the 1-year post-stroke dementia (PSD) rates after first-ever and recurrent stroke are ~10 and 30...

Postreperfusion Blood Pressure Variability After Endovascular Thrombectomy Affects Outcomes in Acute Ischemic Stroke Patients With Poor Collateral Circulation
Conclusion: Postreperfusion BP management by decreasing BPV may have influence on improving clinical outcome in cases of poor collateral circulation among patients achieving successful recanalization after ERT. Introduction Endovascular recanalization therapy (ERT) has been adopted as standard stroke care in patients with acute ischemic stroke (1–6). Time to recanalization and degree of recanalization are the most important predictors of clinical outcomes after ERT (7). Before recanalization, an effort to reduce the time from symptom onset to reperfusion is critical for penumbral salvage. After recanalization...

The Paradoxical Protective Effect of Liver Steatosis on Severity and Functional Outcome of Ischemic Stroke
Conclusions: Our study shows that a higher burden of liver steatosis seems to be associated with less severe stroke and better functional outcome after ischemic stroke or TIA. Introduction Non-alcoholic fatty liver disease (NAFLD) is a spectrum of diseases from simple steatosis to steatohepatitis with varying degree of fibrosis, and liver cirrhosis (1, 2). NAFLD is becoming the most common chronic liver disease worldwide including Korea, affecting approximately 25% of the general population (3, 4). NAFLD is closely associated with obesity, insulin resistance, and type 2 diabetes mellitus, and is even recognized as ...

Frequency of Hemorrhage on Follow Up Imaging in Stroke Patients Treated With rt-PA Depending on Clinical Course
Conclusions: Frequency of hemorrhagic transformation in Routine follow-up brain imaging and consecutive changes in therapeutic management were different depending on clinical course measured by NHISS score. Introduction Brain imaging 24–36 h after systemic thrombolysis for acute ischemic stroke is recommended in American Stroke Association and European Stroke Organization guidelines (1, 2). Brain imaging is performed to detect secondary bleeding or hemorrhagic transformation in order to adapt medical stroke prevention if necessary. Guideline recommendations are based on the results of the first study on rt-PA...

Influence of Sex on Stroke Prognosis: A Demographic, Clinical, and Molecular Analysis
Conclusion Our data suggest that women who suffer from IS present with a poorer functional outcome than men at 3-months, regardless of other preclinical and clinical factors during the acute phase. These relationships seem to be mediated by atrial dysfunction and inflammation. The inflammatory response is slightly higher in women; however, there are no sex differences in their functional behavior. There is a probable relationship between the molecular marker of atrial dysfunction NT-proBNP and worse functional outcome in women, and the connection seems to be more important in cardioembolic stroke patients. In patients wi...
