Microbleed Status and 3-Month Outcome After Intravenous Thrombolysis in 717 Patients With Acute Ischemic Stroke Clinical Sciences
Conclusions— Poor outcome or sICH was not associated with CMB presence or burden on pre–intravenous thrombolysis magnetic resonance imaging after adjustment for confounding factors. An individual patient data meta-analysis is needed to determine whether a subgroup of patients with CMBs carries an independent risk of poor outcome that might outweigh the expected benefit of intravenous thrombolysis.

Endovascular Treatment for Acute Ischemic Stroke in the Setting of Anticoagulation Brief Reports
Conclusions— Intra-arterial therapy seems to be safe in patients taking OACs; however, our study showed a nonsignificant increase in hemorrhage and mortality with a nonsignificant decrease in good outcomes in comparison with non-OAC patients. Although these nominal differences may have been related to older age and more comorbidities in the OAC group, larger studies are needed to confirm our findings given our limited sample size.

Fibrin Clot Permeability as a Predictor of Stroke and Bleeding in Anticoagulated Patients With Atrial Fibrillation Clinical Sciences
Background and Purpose—Formation of denser fiber networks has been reported in atrial fibrillation and ischemic stroke. In this longitudinal cohort study, we evaluated whether fibrin clot density may predict thromboembolic and bleeding risk in patients with atrial fibrillation on vitamin K antagonists.Methods—In 236 patients with atrial fibrillation receiving vitamin K antagonists treatment, we measured ex vivo plasma clot permeability (Ks), a measure of the pore size in fibrin networks.Results—During a median follow-up of 4.3 (interquartile range, 3.7–4.8) years, annual rates of ischemic stroke or transient ischem...

Multilocus Genetic Risk Score Associates With Ischemic Stroke in Case-Control and Prospective Cohort Studies Clinical Sciences
Conclusions— A multilocus GRS based on common variants for established cardiovascular risk factors was significantly associated with IS both in clinic-based samples and in the general population. However, the improvement in clinical risk prediction was found to be small.

Survivor gives us a lens into regional systems of care for acute ischemic stroke in North Dakota
I just got back from the North Dakota Mission: Lifeline STEMI and Acute Stroke Conference in Bismark, ND. I had a great time and I learned a lot. I often get asked to speak in various venues about acute STEMI and 12-lead ECG interpretation, but for this conference they wanted me to talk mostly about stroke. That turned out to be a good thing because it forced me to read the 2013 AHA / ASA Guildelines for the Early Management of Patients With Acute Ischemic Stroke to make sure I was asking intelligent questions during the panel discussion (which I moderated) and also giving accurate information for the class I taught about ...

Self-Report of Stroke, Transient Ischemic Attack, or Stroke Symptoms and Risk of Future Stroke in the Reasons for Geographic And Racial Differences in Stroke (REGARDS) Study Original Contributions
Conclusions— Results suggest a spectrum of risk from stroke symptoms to TIA, DS, and RS, and imply a need for establishing these categories in health screenings to manage risk for future stroke, reinforcing the clinical importance of stroke history including the presence of stroke symptoms.

Frequency and Predictors of Stroke After Acute Myocardial Infarction: Specific Aspects of In-Hospital and Postdischarge Events Clinical Sciences
Conclusions— The present study describes specific predictors of in-hospital and postdischarge stroke in patients with AMI. It showed a marked increase in the risk of death, both during hospitalization and in the year after AMI. After hospital discharge, stroke remains a rare event and is mostly associated with high cardiovascular risk.

Predictors of Acute Stroke Mimics in 8187 Patients Referred to a Stroke Service
Conclusions: One third of the patients seen by a stroke team over 10 years had a stroke mimic. Factors associated with a stroke mimic may be ascertained by an emergency physician before calling the stroke team.

Acute infection contributes to racial disparities in stroke mortality
Conclusions: Acute infection disproportionately increases the risk of stroke death for non-Hispanic blacks, independently of atrial fibrillation. Stroke incidence did not explain this finding. Acute infection appears to be one factor that contributes to the black–white disparity in stroke mortality.

Stroke in the Young: Etiologies and Risk Factors (P7.124)
CONCLUSIONS: Stroke in the young shares many of the same common modifiable risk factors as stroke in the elderly including hypertension, hyperlipidemia, diabetes, and tobacco abuse. Other unique disease processes also contribute to stroke in this age group, often less modifiable. Given the devastating morbidity and mortality of stroke in this age group, a larger public health effort for primary and secondary prevention of stroke in the young should be aggressively pursued.Disclosure: Dr. Govind has nothing to disclose.

Risk factors for ischemic stroke and its subtypes in Chinese vs. Caucasians: Systematic review and meta‐analysis
ConclusionOur study showed a lower prevalence of atrial fibrillation, ischemic heart disease and hypercholesterolemia in Chinese, and mostly similar risk factor associations in Chinese and Caucasian ischemic stroke patients. Further analyses of individual patient data to allow adjustment for confounders are needed to confirm and extend these findings.

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...
