It is not known whether patients with atrial fibrillation (AF) ischemic stroke despite oral anticoagulant therapy are at increased risk for further recurrent strokes or how ongoing secondary prevention should be managed.
Background and Purpose— Blood pressure (BP) lowering is often conducted as part of general acute management in patients with intracerebral hemorrhage. However, the relationship between BP after antihypertensive therapy clinical outcomes not fully known. Methods— Hyperacute (<3 hours from onset) hemorrhage initial systolic (SBP) >180 mm Hg were included. All received intravenous treatment, based on predefined protocol to lower maintain SBP 120 160 Hg. BPs measured every 15 minutes...
Large clinical trials are lack of data on non-vitamin K antagonist oral anticoagulants for acute stroke patients.To evaluate the choice at hospital discharge in patients with nonvalvular atrial fibrillation and clarify underlying characteristics potentially affecting that using multicenter Stroke Acute Management Urgent Risk-factor Assessment Improvement-NVAF registry (ClinicalTrials.gov NCT01581502).The study included 1192 ischemic stroke/transient attack (527 women, 77·7 ± 9·9 years old)...
We compared outcomes after treatment with direct oral anticoagulants (DOACs) and vitamin K antagonists (VKAs) in patients atrial fibrillation (AF) a recent cerebral ischemia.We conducted an individual patient data analysis of seven prospective cohort studies. included AF ischemia (<3 months before starting anticoagulation) minimum follow-up 3 months. analyzed the association between type anticoagulation (DOAC versus VKA) composite primary endpoint (recurrent ischemic stroke [AIS],...
The "1-3-6-12-day rule" for starting direct oral anticoagulants (DOACs) in patients with nonvalvular atrial fibrillation after acute ischemic stroke or transient attack recommends timings that may be later than used clinical practice. We investigated more practical optimal timing of DOAC initiation according to severity. combined data prospective registries Japan, Stroke Acute Management Urgent Risk-factor Assessment and Improvement-nonvalvular (September 2011 March 2014) RELAXED (February...
Aims This study was performed to determine the short-term risk-benefit profiles of patients treated with oral anticoagulation for acute ischemic stroke or transient attack using a multicenter, prospective registry. Methods A total 1137 (645 men, 77 ± 10 years old) stroke/transient taking warfarin (662 patients) non-vitamin K antagonist anticoagulants (dabigatran in 205, rivaroxaban 245, apixaban 25 nonvalvular atrial fibrillation who completed three-month follow-up survey were studied....
Background and Purpose— The associations between early blood pressure (BP) variability clinical outcomes in patients with intracerebral hemorrhage after antihypertensive therapy, recently clarified by a post hoc analysis of Intensive Blood Pressure Reduction Acute Cerebral Hemorrhage Trial 2 (INTERACT2), were confirmed using the Stroke Management Urgent Risk-factor Assessment Improvement (SAMURAI)-intracerebral study cohort. Methods— Patients hyperacute (<3 hours from onset) initial...
The role of early hospital arrival in improving poststroke clinical outcomes patients without reperfusion treatment remains unclear. This study aimed to determine whether was associated with favorable or minor stroke.This multicenter, hospital-based included 6780 consecutive (aged, 69.9±12.2 years; 63.9% men) ischemic stroke who were prospectively registered Fukuoka, Japan, between July 2007 and December 2014. Onset-to-door time categorized as T0-1, ≤1 hour; T1-2, >1 ≤2 hours; T2-3, >2 ≤3...
Background Among patients with ischemic stroke and atrial fibrillation, which ones are at high risk of recurrent is unclear. This study aimed to determine whether left size was associated long‐term recurrence in nonvalvular fibrillation. Methods Results In this multicenter prospective cohort study, fibrillation hospitalized for acute were enrolled followed up after discharge. Indexed‐left diameter obtained by dividing body surface area. Cause‐specific subdistribution hazard ratios estimated...
Background and Purpose— The discrimination between paroxysmal sustained (persistent or permanent) atrial fibrillation (AF) has not been considered in the approach to secondary stroke prevention. We aimed assess differences clinical outcomes mostly anticoagulated patients with AF who had previous ischemic transient attack. Methods— Using data from 1192 nonvalvular acute attack were registered SAMURAI-NVAF study (Stroke Management With Urgent Risk-Factor Assessment Improvement-Nonvalvular AF;...
The purpose of this study was to examine the relationships between glucose parameters obtained by continuous monitoring and clinical outcomes in acute stroke patients.
Background:We determined the 2-year long-term risk-benefit profile in patients with stroke or transient ischemic attack (TIA) receiving warfarin direct oral anticoagulants (DOACs) for nonvalvular atrial fibrillation (NVAF) using a prospective, multicenter, observational registry Japan.
Magnetic resonance imaging (MRI), including perfusion MRI with arterial spin labeling (ASL) and diffusion-weighted (DWI), are applied in the periictal detection of circulatory metabolic consequences associated epilepsy. Although previous report revealed that prolonged ictal hyperperfusion on ASL can be firstly detected cortical hyperintensity cytotoxic edema DWI secondarily obtained from an epileptically activated cortex, hemodynamic state has not been fully demonstrated. We retrospectively...
Magnetic resonance imaging (MRI), including perfusion MRI with three-dimensional pseudocontinuous arterial spin labeling (ASL) and diffusion-weighted (DWI), are applied in the periictal (including ictal postictal) detection of circulatory metabolic consequences associated epilepsy. Our previous report revealed that hyperperfusion can firstly be detected on ASL, cortical hyperintensity cytotoxic edema secondarily obtained DWI from an epileptically activated cortex. Although magnetic...
Importance Patients with atrial fibrillation (AF) who have ischemic stroke despite taking oral anticoagulation therapy (OAT) a very high risk of recurrence. Left appendage occlusion (LAAO) is mechanical prevention strategy that may provide additional protection in patients thromboembolic events under OAT. Objective To compare percutaneous LAAO continuing OAT alone regarding AF had event Design, Setting, and Participants This cohort study was propensity score–matched comparison the STR-OAC...
It remains unclear how chronic kidney disease and its underlying pathological conditions, dysfunction, damage, are associated with cardiovascular outcomes. This study aimed to determine whether dysfunction (ie, decreased estimated glomerular filtration rate), damage proteinuria), or both the long-term outcomes after ischemic stroke.A total of 12 576 patients (mean age, 73.0±12.6 years; 41.3% women) stroke who were registered in a hospital-based multicenter registry, Fukuoka Stroke Registry,...
We report a 60-year-old right-handed Japanese man who showed an isolated persistent typing impairment without aphasia, agraphia, apraxia or any other neuropsychological deficit. coined the term ‘dystypia’ for this peculiar manifestation. The symptom was caused by infarction in left frontal lobe involving foot of second convolution and operculum. patient’s not attributable to disturbance linguistic process, since he had no aphasia agraphia. motor execution process either, apraxia. Thus, his...
Conjugate eye deviation (CED) occurs frequently in patients with acute stroke. The purpose of this study was to elucidate the factors that correlate CED as well relationship between and outcomes intracerebral hemorrhage.A total 211 supratentorial hemorrhage were recruited a multicenter, prospective study. assessed National Institutes Health Stroke Scale "best gaze" subscore ≥1. Hematoma location volume on CT.Forty-five percent had CED. On multivariable analysis, right-sided lesion (OR, 2.36;...
Although intravenous recombinant tissue-type plasminogen activator (rt-PA) therapy can be effective for ischemic stroke, a considerable percentage of patients do not receive any benefit as result early recanalization failure. We aimed to investigate the factors associated with failure following rt-PA therapy.Patients acute stroke and internal carotid artery (ICA) or middle cerebral occlusion on initial magnetic resonance angiography (MRA) who received within 3 h onset underwent follow-up MRA...
