Noncontrast Computed Tomography Hypodensities Predict Poor Outcome in Intracerebral Hemorrhage Patients Clinical Sciences
Conclusions— The presence of noncontract CT hypodensities at baseline independently predicts poor outcome and comes as a useful and widely available addition to our ability to predict ICH patients’ clinical evolution.

The Sex, Age, Medical History, Treatment, Tobacco Use, Race Risk (SAMe TT2R2) Score Predicts Warfarin Control in a Singaporean Population
Warfarin reduces stroke risk in atrial fibrillation (AF) patients but requires ongoing monitoring. Time in therapeutic range (TTR) is used as a measure of warfarin control, with a TTR less than 60% associated with adverse patient outcomes. The Sex, Age, Medical history, Treatment, Tobacco use, Race (SAMe-TT2R2) score has been identified as a model able to predict warfarin control, but this has been tested in mainly Caucasian populations. Therefore, the aim of this study was to determine the ability of the SAMe-TT2R2 score to predict warfarin control in a Singaporean population consisting of Chinese, Malay, and Indian race.

Patients' Characteristics Affect the Survival Benefit of Warfarin Treatment for Hemodialysis Patients with Atrial Fibrillation. A Historical Cohort Study
Background: Stroke prevention in dialysis-dependent patients with atrial fibrillation (AF) is an unresolved clinical dilemma. Indeed, no randomized controlled trial evaluating the efficacy and safety of oral anticoagulants in this population, has been conducted so far. Observational research on the use of warfarin in patients on dialysis has shown conflicting results. This uncertainty is mirrored by the wide variations in warfarin prescription patterns across centers. We sought to evaluate the association between the use of vitamin K antagonists (VKAs) and mortality among hemodialysis patient with AF and to assess potentia...

Novel oral anticoagulants for the secondary prevention of cerebral ischemia: a network meta-analysis
Conclusions: The three NOACs showed differences in terms of safety and efficacy for secondary stroke prevention in NVAF. Our findings can serve only as hypothesis generation and require independent confirmation in head-to-head RCTs, owing to the sparse available evidence and increased uncertainty in both indirect effect estimates and ranking of treatments.

Risk Profile of Symptomatic Lacunar Stroke Versus Nonlobar Intracerebral Hemorrhage Brief Reports
Conclusions— The risk factor profile of dICH differs from that associated with LS. This might be used for disease risk stratification at individual level.

Warfarin-Resistant Deep Vein Thrombosis during the Treatment of Acute Ischemic Stroke in Lung Adenocarcinoma
A 66-year-old man with acute ischemic stroke in the setting of lung adenocarcinoma developed acute-onset deep vein thrombosis (DVT) of the lower limbs after changing to warfarin from a heparin combination. The diagnosis of warfarin-resistant DVT was established based on the laboratory data and clinical evaluation. Heparin administration resulted in good control of thrombin regulation. Cancer patients are at high risk of venous thromboembolism, and the combination of these 2 conditions is known as Trousseau's syndrome.

Risk of Ischemic Stroke in High Risk Atrial Fibrillation Patients during Periods of Warfarin Discontinuation for Surgical Procedures
Importance: The risk of ischemic stroke during periods of warfarin discontinuation for surgical procedures is recognized but not well characterized. Objective: The study aimed to quantitate the risk of ischemic stroke associated with high risk atrial fibrillation during periods of warfarin discontinuation. Design, Setting and Participants: A cohort of 4,060 patients (mean follow-up period of 3.5 ± 1.3 years) were randomized into the Atrial Fibrillation Follow-Up Investigation of Rhythm Management study. Patients enrolled in the study had atrial fibrillation plus at least one other risk factor for stroke or death: age ≥6...

Effects of Pretreatment with Warfarin or Rivaroxaban on Neurovascular Unit Dissociation after Tissue Plasminogen Activator Thrombolysis in Ischemic Rat Brain
In this study, we assessed the risks and benefits of pre-treatment with warfarin or rivaroxaban after tissue-type plasminogen activator (tPA) thrombolysis in ischemic rat brain.

Cost-Effectiveness of Oral Anticoagulants for Ischemic Stroke Prophylaxis Among Nonvalvular Atrial Fibrillation Patients Clinical Sciences
Conclusions— All the newer oral anticoagulants compared were more effective than adjusted dosed warfarin. Our model showed that apixaban was the most effective anticoagulant in a general atrial fibrillation population and has an incremental cost-effectiveness ratio <$50 000/QALY. For those with higher stroke risk (CHADS2≥3), dabigatran was the most cost-effective treatment option.

Carotid Atherosclerosis and Stroke in Atrial Fibrillation: The Atherosclerosis Risk in Communities Study Brief Reports
Conclusions— Increased cIMT and presence of carotid plaque are associated with increased risk of ischemic stroke in individuals with AF. Furthermore, they may improve risk prediction of stroke, over and above the CHA2DS2-VASc score.

Causes of Ischemic Stroke in Patients with Non-Valvular Atrial Fibrillation
Background: Oral anticoagulants (OACs) reduce the incidence of embolic events associated with non-valvular atrial fibrillation (NVAF); however, ischemic stroke can still occur in such patients. Although there are various causes of ischemic stroke in patients with NVAF, their medication status at onset has scarcely been studied. This retrospective study aimed to determine the underlying causes of ischemic stroke in patients with NVAF in relation to pre-stroke anticoagulation. Methods: Among Japanese patients with acute ischemic stroke enrolled in the Fukuoka Stroke Registry from June 2007 to May 2013, 1,302 patients with NV...

Ischemic Stroke Risk in Patients With Atrial Fibrillation and CHA2DS2-VASc Score of 1: Systematic Review and Meta-Analysis Brief Reports
Conclusions— Our meta-analysis of ischemic stroke risk in atrial fibrillation patients suggests that those with CHA2DS2-VASc score of 1 may be considered for a novel oral anticoagulant, but because of high heterogeneity, the decision should be based on individual patient characteristics.

D-Dimer versus International Normalized Ratio of Prothrombin Time in Ischemic Stroke Patients Treated with Sufficient Warfarin
In patients receiving chronic warfarin therapy, the international normalized ratio of prothrombin time (PT-INR) reportedly correlates with the incidence, size, severity, and outcome of ischemic stroke, and thus there are guidelines for the optimal PT-INR range that is to be maintained during secondary or primary prevention of ischemic stroke. However, the details of ischemic stroke in patients in whom an optimal PT-INR is maintained by warfarin therapy have not been thoroughly investigated. We conducted a retrospective study to determine the predictors of the size, severity, and outcome of ischemic stroke occurring in pati...
