Left Atrial Appendage Morphology and Embolic Stroke of Undetermined Source: A Cross-Sectional Multicenter Pilot Study
The left atrial appendage (LAA) is the main source of thrombus in atrial fibrillation, and there is an association between non-chicken wing (NCW) LAA morphology and stroke. We hypothesized that the prevalence of NCW LAA morphology would be higher among patients with cardioembolic (CE) stroke and embolic stroke of undetermined source (ESUS) than among those with noncardioembolic stroke (NCS).

Burden of Premature Atrial Complexes and Risk of Recurrent Stroke and Death in Patients with Mild to Moderate Ischemic Stroke
Premature atrial complexes (PACs) meet increased attention as a potential intermediary between sinus rhythm and atrial fibrillation (AF). Patients with even high numbers of PACs do not fulfill current guidelines for oral anticoagulation treatment though an associated stroke risk is suspected. Objective: We aimed to determine whether a high number of PACs or runs of AF less than 30 seconds in 2-day continuous electrocardiogram (ECG) recording was associated with risk of recurrent ischemic stroke/transient ischemic attack (TIA) or death in a large cohort of patients with acute ischemic stroke or TIA and no prior AF.

Risk of Ischemic Stroke and Major Bleeding in Patients With Atrial Fibrillation and Cancer
Background: Atrial fibrillation (AF) is an important risk factor for ischemic stroke. Cancer may increase the risk both of ischemic stroke and of bleeding. Less is known about risk of ischemic stroke and bleeding among cancer patients with AF, complicating the prevention of ischemic stroke in these patients. Methods: Register based cohort study comprising all Swedish patients hospitalized with a primary diagnosis of AF from July 1, 2005 until December 31, 2014. Patients with cancer diagnosis were compared to the rest of the cohort.

Automated Continuous Electrocardiogram Monitoring Accelerates the Detection of Atrial Fibrillation after Ischemic Stroke or Transient Ischemic Attack on a Hyper Acute Stroke Unit
Background and Aim: Rapid and sensitive detection of atrial fibrillation (AF) is of paramount importance for initiation of adequate preventive therapy after stroke. Stroke Unit care includes continuous electrocardiogram monitoring (CEM) but the optimal exploitation of the recorded ECG traces is controversial. In this retrospective single-center study, we investigated whether an automated analysis of continuous electrocardiogram monitoring (ACEM), based on a software algorithm, accelerates the detection of AF in patients admitted to our Stroke Unit compared to the routine CEM.

Transient atrial mechanical dysfunction assessed in acute phase of embolic stroke of undetermined source
Background and Purpose: Paroxysmal atrial fibrillation (PAF) has been suggested as a major cause of embolic stroke of undetermined source (ESUS). Transient atrial mechanical dysfunction (stunning) frequently occurs after conversion of atrial fibrillation to sinus rhythm. The study aim was to determine if reversible atrial mechanical dysfunction in ESUS could help elucidate the mechanism of stroke. Methods: Eighty-five consecutive patients with acute ischemic stroke were enrolled according to the following inclusion criteria: [1] ≥55 years old; [2] normal sinus rhythm upon admission; [3] no apparent embolic source; and [4...

Prehospital continuous ECG is valuable for very early detection of atrial fibrillation in patients with acute stroke
Atrial fibrillation (AF) is a major risk factor for recurrent stroke and death in ischemic stroke patients.1,2 Due to its elusive nature AF often goes undetected.3 The use of continuous ECG (cECG) improves detection rates.4,5 Early detection, and therefore timely initiation of oral anticoagulant treatment may improve the prognosis after stroke.6 –8 In acute ischemic stroke patients guidelines recommend an admission in-hospital 12-lead ECG followed by at least 24 or 72 hours of continuous monitoring (American and European guidelines respectively).

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.

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.

Cost-Effectiveness Analysis of Percutaneous Patent Foramen Ovale Closure Preventing Secondary Ischemic Stroke in Japan
Cryptogenic ischemic stroke is a type of ischemic stroke for which the mechanism of onset and etiology cannot be explained or specified by any known mechanisms/factors. The possible involvement of patent foramen ovale (PFO) in the etiology of cryptogenic ischemic stroke has been reported.1 It was previously reported that occult atrial fibrillation and PFO were embolic sources that caused cryptogenic ischemic stroke.2 PFO is an opening formed during the course of fetal atrial septum development. Usually, it closes spontaneously after birth; however, PFO remains patent after maturation to adulthood.

Association Between Oral Anticoagulants and Stroke Severity at Onset in Elderly Patients with Cardioembolic Stroke Due to Non-Valvular Atrial Fibrillation
The prevention of cardioembolic stroke is an important public health priority in Japan due to its high prevalence in elderly individuals. Compared to their younger counterparts, elderly patients with cardioembolic stroke are more likely to have multiple comorbidities, a higher risk of serious complications, such as pneumonia and heart failure, and cognitive impairments (e.g., dementia or delirium), which may adversely affect their ability to participate in active rehabilitation. These factors negatively affect clinical outcomes, and many elderly stroke survivors require long-term care despite the early implementation of intensive therapy.

Neurogenic cardiac outcome in patients after acute ischemic stroke: The brain and heart connection
This study aims to identify the association between cardiac outcomes and middle cerebral artery (MCA) ischemic stroke, with or without insular cortex involvement, as well as the impact of new-onset atrial fibrillation (AF) after AIS on recurrent stroke.

Outcomes in patients with ischaemic stroke undergoing endovascular thrombectomy: Impact of atrial fibrillation
Endovascular thrombectomy (EVT) is associated with good clinical outcomes in ischaemic stroke, but the risk of intracerebral haemorrhage (ICH) and mortality remains common following ischaemic stroke. The effect of concomitant atrial fibrillation (AF) on clinical outcomes following acute ischaemic stroke in patients receiving EVT remains unclear. The aim is to investigate associations between AF and intracerebral haemorrhage and all-cause mortality at 90 days in patients with ischaemic stroke undergoing EVT.

Higher Frequency of Atrial Fibrillation Linked to Colder Seasons and Air Temperature on the Day of Ischemic Stroke Onset
Background: Whether a seasonal variation of atrial fibrillation among acute ischemic stroke (AIS) patients occurs is unknown. We studied the distribution of atrial fibrillation across seasons and air temperatures in a cohort of AIS patients.Methods: We selected 899 AIS patients from the Argentinean Stroke Registry (ReNACer), who were admitted to 43 centers in the Province of Buenos Aires. We recorded the minimum and maximum temperatures at local weather centers on the day and the city where each stroke occurred. We used the goodness-of-fit χ2 test to assess the distribution of atrial fibrillation across seasons and air te...
