Identifying a High Stroke Risk Subgroup in Individuals with Heart Failure
Conclusions: The combination of previous stroke/TIA and DM increases the incidence of stroke in participants with HF without AF. No analyzed subgroup had a stroke rate high enough to make it likely that the benefits of warfarin would outweigh the risks.

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...

Metformin-inclusive Therapy Reduces the Risk of Stroke in Patients with Diabetes: A 4-Year Follow-up Study
Metformin is a kind of oral hypoglycemic agents commonly prescribed to patients with diabetes mellitus. Although past studies had proven its protective effect on cardiovascular risk and related mortality, the evidence of metformin on stroke prevention was still insufficient and conflicting. Our study randomly selected 14,856 patients with diabetes from the database provided by the Taiwan National Health Research Institute, and 2 cohorts were formulated according to whether metformin was in the prescription record. All cases were followed up for 4 years to track their stroke incidence. As a result, 701 (17.5%) of 3999 diabe...

Tissue Plasminogen Activator Thrombolytic Therapy for Acute Ischemic Stroke in 4 Hospital Groups in Japan
In October 2005 in Japan, the recombinant tissue plasminogen activator (tPA) alteplase was approved for patients with acute ischemic stroke within 3 hours of onset at a dose of 0.6 mg/kg. The present study was undertaken to assess the safety and efficacy of alteplase in Japan. Between October 2005 and December 2009, a total of 114 consecutive patients admitted to 4 hospitals received intravenous tPA within 3 hours of stroke onset. Clinical backgrounds and outcomes were investigated. The patients were divided into 2 chronological groups: an early group, comprising 45 patients treated between October 2005 and December 2007,...

Another possible determinant for ischemic stroke with nonvalvular atrial fibrillation other than conventional oral anticoagulant treatment: The relationship between whole blood viscosity and stroke ☆
Prevention of ischemic stroke complication of atrial fibrillation (AF) is the crucial target in the disease. Stroke is largely prevented by warfarin and the introduction of new oral anticoagulants. While warfarin reduces stroke by 60 –70%, new oral anticoagulants provide at least equal success to this reduction with appropriate dose and treatment compliance.1,2 Nonetheless, we still encounter thromboembolic ischemic stroke in clinical practice in AF patients taking oral anticoagulants (OAC) and once experienced, stroke can hav e devastating consequences for the patients.

Antiphospholipid Syndrome of Late Onset: A Difficult Diagnosis of a Recurrent Embolic Stroke
A 77-year-old woman with atrial fibrillation (AF) treated with warfarin had a cortical left middle cerebral artery (MCA) stroke (October 2009, international normalized ratio [INR], 1.6) and a cortical left frontal stroke (October 2011, INR, 1.9). Anticoagulation was adjusted. In October 2011, she had a right frontal stroke (INR, 2.3). Acetylsalicylic acid (ASA) was temporally added to the treatment. In June 2013, she had a left occipital stroke (INR, 2.3). Warfarin was changed to rivaroxaban. In August 2013, she had a right occipital stroke.

Comparison of primary and secondary stroke prevention in patients with nonvalvular atrial fibrillation: Results from the RAFFINE registry
Atrial fibrillation (AF) is a predictor of severe stroke and early death in acute ischemic stroke patients.1 The prevalence of AF has increased as the Japanese population has aged.2 AF has been more common among patients with ischemic stroke than previously reported.3 In particular, AF patients with a history of stroke or TIA have had higher risks for stroke, hemorrhagic events, and death compared to those without.4,5 In these previous studies, most patients received warfarin for anticoagulation therapy.

Warfarin versus Aspirin for Prevention of Stroke in Heart Failure: A Meta-analysis of Randomized Controlled Clinical Trials
Conclusions: Compared with aspirin, warfarin reduced the risk of stroke while conferring an increased risk of major hemorrhage. Warfarin does not increase mortality or confer an increased risk of ICH compared with aspirin.

Factors Associated with Proximal Carotid Axis Occlusion in Patients with Acute Stroke and Atrial Fibrillation
Conclusions: Female sex, advanced age, history of systemic embolism, and higher BNP level were independently associated with more proximal carotid axis occlusion. Patients with AF having these factors may be prone to have relatively large thrombi in the heart.

Reduced Smoke-like Echo and Resolved Thrombus in the Left Atrium with Rivaroxaban Therapy in an Acute Cardioembolic Stroke Patient
We report a case of a nonvalvular atrial fibrillation (NVAF) patient with acute cardioembolic stroke in whom rivaroxaban, an oral direct factor Xa inhibitor, reduced a smoke-like echo in the left atrium and resolved a thrombus in the left atrial appendage. A 71-year-old man was admitted because of the sudden onset of right hemiplegia and aphasia and was diagnosed with acute cardioembolic stroke associated with NVAF. The patient had not been treated with warfarin before admission, and rivaroxaban therapy (15 mg once daily) was initiated. Transesophageal echocardiography was performed on day 8 and a mobile thrombus was foun...

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...

Risk of Stroke Outcomes in Atrial Fibrillation Patients Treated with Rivaroxaban and Warfarin
In a previous real-world study, rivaroxaban reduced the risk of stroke overall and severe stroke compared with warfarin in patients with nonvalvular atrial fibrillation (NVAF). The aim of this study was to assess the reproducibility in a different database of our previously observed results (Alberts M, et al. Stroke. 2020;51:549-555) on the risk of severe stroke among NVAF patients in a different population treated with rivaroxaban or warfarin.

Rate of Antithrombotic Drug use and Clinical Outcomes According to CHADS2 Scores in Patients With an Initial Cardioembolic Stroke who had Nonvalvular Atrial Fibrillation
This study investigated the relationship between CHADS2 scores and the rate of antithrombotic drug use and clinical outcomes in patients with an initial cardioembolic stroke who had nonvalvular atrial fibrillation (NVAF).Methods: In 234 patients (135 men and 99 women; mean age [±SD] 76 ± 11 years) with initial cardiogenic cerebral embolism with NVAF who were admitted to our hospital between April 2007 and March 2011, the CHADS2 score, use of warfarin, and clinical outcomes were retrospectively investigated.Results: CHADS2 scores were as follows: 0 points, n = 21 (9%); 1 point, n = 72 (31%); 2 points, n = 92 (39%); 3 poin...

Repeated Episodes of Ischemic Stroke over a Short Period in a Patient with Essential Thrombocythemia on Anticoagulant Therapy
A 69-year-old man who had essential thrombocythemia, for which he was taking no medications, suddenly developed aphasia and right hemiplegia and was admitted to the hospital. He was thought to have had an embolic stroke and was initially treated with warfarin. Although the international normalized ratio was in the therapeutic range, he had 3 additional ischemic stroke episodes with the same symptoms after the index stroke. Magnetic resonance angiographic examinations revealed serial changes in middle cerebral artery stenosis. After administration of an antiplatelet agent and hydroxyurea, he had no additional strokes.
