Rivaroxaban and Apixaban Reduce Hemorrhagic Transformation After Thrombolysis by Protection of Neurovascular Unit in Rat Basic Sciences
Conclusions— This study shows a lower risk of intracerebral hemorrhage after tissue-type plasminogen activator treatment in rats with ischemic stroke that are pretreated with rivaroxaban and apixaban compared with pretreatment with warfarin. Reducing neurovascular dissociation by rivaroxaban and apixaban compared with warfarin could partly explain a reduction in hemorrhagic complications reported in clinical studies.

Rivaroxaban for Stroke Prevention in East Asian Patients From the ROCKET AF Trial Clinical Sciences
Conclusions— Observed relative efficacy and safety of rivaroxaban versus warfarin were similar among patients within and outside East Asia. Rivaroxaban, 20 mg once daily, is an alternative to warfarin for stroke prevention in East Asians with nonvalvular atrial fibrillation.

Risk Factors for Computed Tomography Angiography Spot Sign in Deep and Lobar Intracerebral Hemorrhage Are Shared Brief Reports
Conclusions— The most potent associations with spot sign are shared between deep and lobar ICH, suggesting that the acute bleeding process that arises in the setting of different chronic small vessel diseases shares commonalities.

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.

Warfarin Versus Aspirin for Prevention of Cognitive Decline in Atrial Fibrillation: Randomized Controlled Trial (Birmingham Atrial Fibrillation Treatment of the Aged Study) Clinical Sciences
Conclusions— We found no evidence that anticoagulation confers clinically important protection over aspirin against cognitive decline as measured by the Mini-Mental State Examination in atrial fibrillation in the first 33 months of treatment other than that provided by preventing clinical stroke.

Atrial Fibrillation, Stroke Risk, and Warfarin Therapy Revisited: A Population-Based Study Clinical Sciences
Conclusions— AF is more common than present guidelines suggest. The attributable risk of AF for ischemic stroke increases with age and is close to that of hypertension in individuals aged ≥80 years. Because a majority of patients with AF with increased risk for stroke had not received anticoagulation therapy, there is a large potential for improvement.

Cilostazol Ameliorates Warfarin-Induced Hemorrhagic Transformation After Cerebral Ischemia in Mice Basic Sciences
Conclusions— Cilostazol reduced the warfarin-related risk of HT after ischemia by protecting the vascular endothelial cells. This result suggested that cilostazol administration in patients with acute ischemic stroke might reduce HT.

Imaging of Contrast Medium Extravasation in Anticoagulation-Associated Intracerebral Hemorrhage With Dual-Energy Computed Tomography Basic Sciences
Conclusions— Dual-energy computed tomography allows quantifying CE, as a marker of ongoing bleeding, in a model of anticoagulation-associated ICH. Dabigatran induces less CE in ICH than warfarin and consequently reduces risks of hematoma expansion. This constitutes a potential safety advantage of dabigatran over warfarin. Nevertheless, in case of warfarin anticoagulation, prothrombin complex concentrates reduce this side effect.

Dabigatran Versus Warfarin: Effects on Ischemic and Hemorrhagic Strokes and Bleeding in Asians and Non-Asians With Atrial Fibrillation Clinical Sciences
Conclusions— Hemorrhagic stroke rates were higher on warfarin in Asians versus non-Asians, despite similar blood pressure, younger age, and lower international normalized ratio values. Hemorrhagic strokes were significantly reduced by DE in both Asians and non-Asians. DE benefits were consistent across Asian and non-Asian subgroups.
