Effectiveness and Safety of Apixaban, Dabigatran, and Rivaroxaban Versus Warfarin in Patients With Nonvalvular Atrial Fibrillation and Previous Stroke or Transient Ischemic Attack Clinical Sciences
Conclusions—Results from our study of the 3 NOACs versus warfarin in nonvalvular atrial fibrillation patients with a previous history of stroke/transient ischemic attack are relatively consistent with their respective phase III trials and previous stroke/transient ischemic attack subgroup analyses. All NOACs seemed no worse than warfarin in respect to ischemic stroke, ICH, or major bleeding risk.

Continuation or Discontinuation of Anticoagulation in the Early Phase After Acute Ischemic Stroke Brief Report
Background and Purpose—There is no consensus on whether anticoagulation should be continued or temporarily stopped in patients suffering acute ischemic stroke while using anticoagulation. We assessed treatment variations and outcomes in these patients.Methods—Post hoc analysis of PASS (Preventive Antibiotics in Stroke Study). We included patients with acute ischemic stroke who used anticoagulation at admission. We compared clinical outcomes, thrombotic, and major bleeding events at 3 months.Results—Nine percent (192/2101) of the patients with acute ischemic stroke used anticoagulation at admission (186 vitamin K anta...

Real-World Setting Comparison of Nonvitamin-K Antagonist Oral Anticoagulants Versus Vitamin-K Antagonists for Stroke Prevention in Atrial Fibrillation Clinical Sciences
Conclusions—This meta-analysis confirms the main findings of the randomized controlled trials of dabigatran, rivaroxaban, and apixaban in the real-world setting and, hence, strengthens their validity.

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...

Intake of Dietary Phylloquinone and Menaquinones and Risk of Stroke Stroke
Conclusion In our study, neither dietary phylloquinone nor dietary menaquinones intake were associated with stroke risk.

Vitamin K antagonist-experienced patients with a history of stroke/transient ischaemic attack who switched from warfarin to dabigatran increased their rate of recurrent stroke/transient ischaemic attack compared with those on warfarin
Commentary on: Larsen TB, Rasmussen LH, Gorst-Rasmussen A, et al. Dabigatran and warfarin for secondary prevention of stroke in atrial fibrillation patients: a nationwide cohort study. Am J Med 2014;127:1172–8 . Context Randomised trials have shown that patients with atrial fibrillation (AF) who are treated with a non-vitamin K antagonist oral anticoagulant (NOAC), compared with warfarin, have similar or lower rates of stroke and major bleeding, markedly reduced rates of intracranial bleeding and a consistent pattern of reduced mortality.1 Dabigatran 150 mg two times a day is the only NOAC that can significantly...

Potential new uses of non-vitamin K antagonist oral anticoagulants to treat and prevent stroke
Conclusion: There may be a role for NOACs in stroke prevention and treatment beyond atrial fibrillation. Randomized controlled trials are needed to compare NOACs to current stroke prevention and treatment strategies in certain subgroups of patients with cerebrovascular disease.

A Narrative Review of Nonvitamin K Antagonist Oral Anticoagulant Use in Secondary Stroke Prevention
The prevalence of atrial fibrillation (AF), the most common cardiac arrhythmia, increases with age, predisposing elderly patients to an increased risk of embolic stroke. With an increasingly aged population the number of people who experience a stroke every year, overall global burden of stroke, and numbers of stroke survivors and related deaths continue to increase. Anticoagulation with vitamin K antagonists (VKAs) reduces the risk of ischemic stroke in patients with AF; however, increased bleeding risk is well documented, particularly in the elderly.

Non-Vitamin K Antagonist Oral Anticoagulants for Stroke Prevention in Asian Patients With Nonvalvular Atrial Fibrillation: Meta-Analysis Clinical Sciences
Conclusions— Our findings suggest that standard-dose NOACs were more effective and safer in Asians than in non-Asians, whereas low-dose NOACs performed similarly in both populations.

Temporal Trends in Pharmacological Stroke Prevention in Patients with Acute Ischemic Stroke and Known Atrial Fibrillation
Oral anticoagulation (OAC) substantially reduces stroke risk in patients with atrial fibrillation (AF) at risk for stroke. Whether non-vitamin K-dependent oral anticoagulants (NOACs) improve OAC use in stroke prevention requires investigation.

Intracranial Hemorrhage Among Patients With Atrial Fibrillation Anticoagulated With Warfarin or Rivaroxaban: The Rivaroxaban Once Daily, Oral, Direct Factor Xa Inhibition Compared With Vitamin K Antagonism for Prevention of Stroke and Embolism Trial in Atrial Fibrillation Clinical Sciences
Conclusions— Among patients with atrial fibrillation treated with anticoagulation, the risk of ICH was higher among Asians, blacks, the elderly, and in those with previous stroke or transient ischemic attack, increased diastolic blood pressure, and reduced platelet count or serum albumin at baseline. The risk of ICH was significantly lower in patients with heart failure and in those who were randomized to rivaroxaban instead of warfarin. The external validity of these findings requires testing in other atrial fibrillation populations.

Safety of Endovascular Thrombectomy in Patients Receiving Non-Vitamin K Antagonist Oral Anticoagulants Brief Reports
Conclusions— Thrombectomy in non–vitamin K antagonist oral anticoagulant patients seems safe although a comparatively high rate of asymptomatic hemorrhagic transformation was noted. Confirmation in larger prospective controlled cohorts is necessary. Clinical Trial Registration— URL: http://www.clinicaltrials.gov. Unique identifier: NCT01850797.
