High Detection Rate of Atrial Fibrillation With Insertable Cardiac Monitor Implantation in Patients With Cryptogenic Stroke Diagnosed by Magnetic Resonance Imaging
Background: Detection and treatment of atrial fibrillation (AF) is a major goal in preventing secondary stroke. Insertable cardiac monitors (ICMs) are available for diagnosis of arrhythmia monitoring in patients with cryptogenic stroke. Magnetic resonance imaging (MRI)-based diagnostic evaluation for acute ischemic stroke subtype classification is common in Japan and can be useful for specific diagnosis of cryptogenic stroke. Purpose: We aimed to investigate the detection rate of AF with an ICM in patients with cryptogenic stroke who were diagnosed by MRI.

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.

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.

Risk Factors and Consequences of Atrial Fibrillation with Rapid Ventricular Response in Patients with Ischemic Stroke Treated with Intravenous Thrombolysis
Atrial fibrillation (AF) is associated with rapid ventricular response (RVR) that increases myocardial demand and blood pressure instability. We investigated the incidence, risk factors, and outcomes of RVR among patients with ischemic stroke receiving treatment with intravenous (IV) recombinant tissue plasminogen activator (rtPA). Consecutive patients with AF who received IV rtPA within 3 hours of symptom onset were included. Vascular risk factors, stroke characteristics, and outcome measures were compared between patients who developed RVR and those who did not. Eighty patients with AF (mean age, 79 years; 46% men) who u...

Higher On-admission Serum Triglycerides Predict Less Severe Disability and Lower All-cause Mortality after Acute Ischemic Stroke
Conclusions: These data suggest that higher fasting TGs on-admission predict less severe disability, reduced disability progression, and all-cause mortality in patients with acute ischemic stroke.

Atrial Fibrillation Detected after Acute Ischemic Stroke: Evidence Supporting the Neurogenic Hypothesis
Background: It is unknown whether atrial fibrillation (AF) detected after acute ischemic stroke is caused by neurogenic or cardiogenic mechanisms. Based on the potential damage to the autonomic nervous system, neurogenic mechanisms could be implicated in the pathophysiology of newly diagnosed AF. To test this hypothesis, we developed a mechanistic approach by comparing a prespecified set of indicators in acute ischemic stroke patients with newly diagnosed AF, known AF, and sinus rhythm.Methods: We prospectively assessed every acute ischemic stroke patient undergoing continuous electrocardiographic monitoring from 2008 thro...

Dilemma of Indication for Thrombolysis in a Patient with Acute Ischemic Stroke Treated with a Novel Oral Anticoagulant
We report the case of a patient treated with dabigatran who developed acute ischemic stroke and was considered for thrombolysis. Because of the prolonged thrombin time (TT), thrombolysis was not performed. Repeated coagulation tests 5 days after stroke, with unchanged anticoagulant (dabigatran) treatment, found 2-fold higher TT and activated partial thromboplastin time (APTT) compared with the values found in the acute stage. Routine coagulation tests (TT and APTT) do not reliably reflect the coagulation features of a patient; therefore, there is an urgent need to develop reliable biomarkers and an adequate guideline to ...

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.

Impaired Renal Function in Stroke Patients with Atrial Fibrillation
In this study, we analyzed frequency and predictors for impaired renal function and its impact on functional outcome in stroke patients with underlying AF.Methods: We analyzed 272 patients with acute ischemic stroke and AF of our prospective, observational stroke database. Estimated glomerular filtration rate (eGFR) was calculated on admission and during hospitalization from the equation of the Modification Diet for Renal Disease. Outcome measures included mortality and functional outcome at 90 days, assessed as modified Rankin Scale (mRS) score.Results: On admission, impaired renal function was found in 41.5% (n = 113)...

Prevalence of Intracranial Stenosis in a Norwegian Ischemic Stroke Population
Conclusions: IS occurs in approximately 10% and is symptomatic in about 7% of a Norwegian ischemic stroke/TIA population. Diabetes mellitus appears to be the major risk factor for IS.

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...

Predictors of Stroke in Atrial Fibrillation
We have greatly enjoyed reading the recently published article by Broughton et al.1 The authors analyzed the data of 4572 participants from the Cardiovascular Health Study and found that the echocardiographic left atrial enlargement detected by echocardiography does not influence the stroke risk observed with atrial fibrillation. We want to remind the predictive role of biomarkers in atrial fibrillation and acute ischemic stroke. Brain natriuretic peptide (BNP) is frequently elevated after an acute stroke and has been shown to be an independent predictor of mortality and a biological marker to distinguish cardioembolic fr...

Association between Atrial Fibrillation and Three-Year Mortality in Nondiabetic Patients with Acute First-Ever Ischemic Stroke
Diabetes mellitus (DM) is a risk factor for atrial fibrillation (AF) and is known to be an important risk factor for death from stroke. The influence of AF on long-term outcomes in patients with ischemic stroke remains controversial. To clarify the exact influence of AF on stroke outcome and exclude the effect from DM, we investigated the influence of AF on the 3-year outcomes of nondiabetic patients with acute first-ever ischemic stroke.

Association of Paroxysmal Supraventricular Tachycardia with Ischemic Stroke: A National Case-Control Study
Cardioembolic stroke accounts for approximately 15%-20% of all ischemic strokes. Atrial fibrillation constitutes one-half to two-thirds of all cardioembolic stroke events. The association of paroxysmal supraventricular tachycardia (PSVT) with ischemic stroke remains unclear. A national case –control study was conducted to identify the risk factors, including PSVT, for ischemic stroke in Taiwan.
