Underweight predicts poststroke cardiovascular events in patients without atrial fibrillation
The purpose of this study was to determine whether underweight is associated with poststroke cardiovascular events and whether such association is different according to the presence of atrial fibrillation (AF).

A Review of the Current Literature and Updates on Embolic Stroke of Undetermined Source (ESUS)
AbstractPurpose of ReviewThe initial ESUS construct presumed that atrial fibrillation (AF) would be detected in a substantial percentage of patients, but subsequent studies have determined that the rate of AF detection is much lower than anticipated, thereby highlighting other potential causes of ESUS. To date, there is no clear consensus supporting PFO closure or anticoagulation in ESUS patients. In this review, we discuss the recent studies on potential causes of ESUS and related work-up as well as report the recent trials on the treatment of ESUS.Recent FindingsSome of the potential causes of ESUS are undetected AF, pat...

How do cardiovascular risk factors correlate with post-stroke cognitive function: Directly or indirectly through stroke severity?
ConclusionThis is the first Chinese study exploring the moderated and mediating associations between cardiovascular risk factors, stroke severity, and cognitive function after stroke. Age, female sex, and atrial fibrillation were directly associated with lower cognition after stroke. The combination of hypertension might have a positive effect on cognition.

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.

Bridging intravenous thrombolysis in patients with atrial fibrillation
ConclusionBridging IVT appears to be a reasonable clinical option in selected patients with AF. Given the increased sICH risk in patients with VKA, subgroup analysis of the randomized controlled trials should analyze whether patients with VKA might benefit from withholding bridging IVT.Registrationclinicaltrials.gov; Unique identifier: NCT03496064.

Detection of hidden atrial fibrillation in primary care using a long-term band-based ECG registration system: The DESCUUBRE-FA study
To assess whether the use of a band-based electrocardiographic (ECG) monitoring system improves the diagnostic accuracy of traditional diagnostic methods for the detection of atrial fibrillation (AF).

Risk of New-Diagnosed Atrial Fibrillation After Transient Ischemic Attack
ConclusionThe risk of NDAF after TIA is clinically relevant. We identified clinical and neuroimaging factors of NDAF. In addition, NT-proBNP was related to NDAF. Our results can be used to evaluate the benefit of long-term cardiac monitoring in selected patients.

Stroke: What's Sleep Got to Do With It?
Summary: Ischemic strokes most often occur between 6 am and 12 am after awakening from sleep but up to 30% occur during sleep. Wake-up strokes (WUS) are new focal neurological deficit(s) persisting for ≥ 24 hours attributable to an ischemic event present on patient awakening. Obstructive sleep apnea (OSA) is a major risk factor for WUS because it compounds the instability of the morning environment and increases the likelihood of cardiovascular events, including hypertension, atrial fibrillation, right-to-left shunts, and stroke. Circadian-driven alterations in structural, homeostatic, and serological factors also pr...

Hypersensitive C ‐reactive protein‐albumin ratio is associated with stroke‐associated pneumonia and early clinical outcomes in patients with acute ischemic stroke
ConclusionsPatients with AIS with a high CAR at admission are more likely to develop SAP during hospitalization and have poor short-term clinical outcomes. These findings might help to timely identify patients at high risk of SAP and provide a basis for further research on prophylactic antibiotic therapy.

Increased Blood Residence Time as Markers of High-Risk Patent Foramen Ovale
AbstractPrevious investigations have suggested that patients with patent foramen ovale (PFO) often have an atrial dysfunction, like to that observed in patients with atrial fibrillation (AF) which may concur to an increased risk of cryptogenic stroke. The aim of the study is to compare the atrial resident time (Rt) of PFO patients to those with sinus rhythm (SR) and AF using patient-specific 3D computational fluid dynamics (CFD) analysis. Models of left atrium (LA) hemodynamics were obtained from time-resolved CT scans and transthoracic echocardiography (TTE). Enrolled patients were divided into three groups: 30 healthy su...

Migraine with aura associates with a higher artificial intelligence: ECG atrial fibrillation prediction model output compared to migraine without aura in both women and men
CONCLUSIONS: Utilizing a novel AI-ECG algorithm on a large group of patients, we demonstrated that patients with MwA have a significantly higher AF prediction model output, implying a higher probability of concurrent paroxysmal or impending AF, compared to MwoA in both women and men. Our results suggest that MwA is an independent risk factor for AF, especially in patients <55 years old, and that AF-mediated cardioembolism may play a role in the migraine-stroke association for some patients.PMID:35676887 | DOI:10.1111/head.14339
