Association Between Dehydration and Short-Term Risk of Ischemic Stroke in Patients with Atrial Fibrillation
We examined whether dehydration increases the risk of ischemic stroke in patients with a recent hospitalization for atrial fibrillation (AF). Data was from 1994 to 2012 from the Myocardial Infarction Data Acquisition System (MIDAS), a repository of in-patient records New Jersey hospitals, for AF hospitalizations (n = 1,282,787). Estimates for the association between AF hospitalization with/without dehydration and ischemic stroke within 30 days post-AF discharge were determined using log-linear multivariable modeling adjusting for socio-demographic factors and comorbid conditions. Within 10 days of discharge for AF, p...

Validation of a Modified CHA2DS2-VASc Score for Stroke Risk Stratification in Asian Patients With Atrial Fibrillation: A Nationwide Cohort Study Clinical Sciences
Conclusions— In this Asian atrial fibrillation cohort, the mCHA2DS2-VASc score performed better than the CHA2DS2-VASc and would further identify atrial fibrillation patients who may derive a positive net clinical benefit from oral anticoagulation.

Do Women With Atrial Fibrillation Experience More Severe Strokes? Brief Report
Background and Purpose—Ischemic strokes associated with atrial fibrillation (AF) are more severe than those of other cause. We aim to study potential sex effects in this context.Methods—In this cross-sectional study, 74 425 adults with acute ischemic stroke from the Austrian Stroke Unit Registry were included between March 2003 and January 2016. In 63 563 patients, data on the National Institutes of Health Stroke Scale on admission to the stroke unit, presence of AF, vascular risk factors, and comorbidities were complete. Analysis was done by a multivariate regression model.Results—Stroke severity in general incr...

Effects of increasing IV tPA-treated stroke mimic rates at CT-based centers on clinical outcomes
Conclusions: Thrombolysis of stroke mimics is increasing at our CT-based spoke hospitals and not at our MRI-based hub hospitals. Caution should be used in interpreting clinical outcomes based on large stroke databases when stroke diagnosis at discharge is unclear. Inadvertent reporting of treated stroke mimics as strokes will artificially elevate overall favorable clinical outcomes with additional downstream costs to patients and the health care system.

CYP2C19 Loss-of-Function Associated with First-Time Ischemic Stroke in Non-surgical Asymptomatic Carotid Artery Stenosis During Clopidogrel Therapy
This study measures effect ofCYP2C19 genotype on ischemic stroke risk during clopidogrel therapy for asymptomatic, extracranial carotid stenosis patients. Using deidentified electronic health records, patients were selected for retrospective cohort using administrative code for carotid stenosis, availability ofCYP2C19 genotype result, clopidogrel exposure, and established patient care. Patients with intracranial atherosclerosis, aneurysm, arteriovenous malformation, prior ischemic stroke, or observation time<1 month were excluded. Dual antiplatelet therapy patients were included. Patients with carotid endarterectomy or ...

Determinants of Emergency Medical Services Use in a Brazilian Population with Acute Ischemic Stroke
This study evaluates the determinants of EMS use in a Brazilian population with acute ischemic stroke. We performed a post hoc analysis of prospectively collected data of consecutive patients admitted to a Brazilian tertiary hospital with acute ischemic stroke. Groups were compared according to their mode of arrival to the hospital: those brought by EMS and those arriving at the hospital by their own means. Among 165 patients evaluated between January and December 2009, 17.6% arrived by EMS and 82.4% arrived by their own means. After multivariate adjustment, individuals with higher National Institutes of Health Stroke Scal...

The search for paroxysmal atrial fibrillation in cryptogenic stroke: Leave no stone unturned
Atrial fibrillation (AF), a well-established cause of ischemic stroke, is found in up to 25% of first strokes.1,2 Most patients with stroke from AF will benefit from anticoagulation for secondary stroke prevention, so finding AF as a cause of ischemic stroke is critical. Many patients with AF have paroxysmal AF (PAF), in which periods of normal sinus rhythm alternate with sometimes brief episodes of AF. Conventional monitoring for AF in the hospital or for a small number of days as an outpatient may therefore miss the diagnosis of PAF. Although most of the data to support anticoagulation for stroke patients with AF come fr...

Bleeding Complications Associated with Warfarin Treatment in Ischemic Stroke Patients with Atrial Fibrillation: A Population-Based Cohort Study
Background: Bleeding events are the major obstacle to the widespread use of warfarin for secondary stroke prevention. Previous studies have not examined the use of risk stratification scores to estimate lifetime bleeding risk associated with warfarin treatment in a population-based setting. The purpose of this study is to determine the lifetime risk of bleeding events in ischemic stroke patients with atrial fibrillation (AF) undergoing warfarin treatment in a population-based cohort and to evaluate the use of bleeding risk scores to identify patients at high risk for lifetime bleeding events.Methods: The resources of the R...

Paradoxical Association of Smoking With In-Hospital Mortality Among Patients Admitted With Acute Ischemic Stroke Stroke
Conclusions Similar to myocardial ischemia, smoking was independently associated with lower inpatient mortality in acute ischemic stroke. This effect may be due to tobacco-induced changes in cerebrovascular vasoreactivity, or may be due in part to residual confounding. Larger, multicenter studies are needed to confirm the finding and the effect on 30-day and 1-year mortality.

Gender Difference in Stroke Case Fatality: An Integrated Study of Hospitalization and Mortality
Conclusions: Among persons hospitalized with a stroke in Nebraska between 2005 and 2009, the crude case fatality rate was 50% higher in women. However, after accounting for age and other variables, adjusted mortality rates were essentially the same for men and women.

Troponin Elevation Predicts Atrial Fibrillation in Patients with Stroke or Transient Ischemic Attack
Conclusions: cTnI elevation predicts new-onset AF on 24-hour Holter measurement in patients with acute ischemic stroke or TIA and may indicate a poorer prognosis and a higher risk of stroke, MI, and death at 3 months.

Brain Natriuretic Peptide: A Relevant Marker to Rule Out Delayed Atrial Fibrillation in Stroke Patient
Detection of new atrial fibrillation (AF) after ischemic stroke is challenging. The aim of the TARGET-AF study was to identify relevant markers for ruling out delayed AF in stroke patients. Early and prolonged Holter electrocardiography (ECG) monitoring during hospitalization was performed systematically in consecutive acute stroke patients naive to AF (no history of AF or no AF on baseline ECG). All clinical and paraclinical data for routine etiologic assessment were collected. The diagnostic value of all parameters significantly associated with AF was assessed by comparison of area under the receiver operating characteri...

The CHA(2)DS(2)-VASc Score Reflects Clinical Outcomes in Nonvalvular Atrial Fibrillation Patients with an Initial Cardioembolic Stroke
Conclusions: The severity of NVAF-induced initial cardioembolic stroke increased with higher CHA(2)DS(2)-VASc scores, and the outcomes were poor. The present study suggests that the CHA(2)DS(2)-VASc score may be useful not only for the evaluation of stroke risk but also for the prediction of clinical outcomes after stroke.
