B-po03-148 risk stratification for ischemic stroke and major bleeding in patients without atrial fibrillation - validity of cha2ds2-vasc and has-bled score
Atrial fibrillation (AF) is the most common arrhythmia. Recent cardiac implantable electronic devices (CIEDs) have led to an improvement in the early detection of AF episodes. ESC guidelines for the management of AF recommend the use of CHA2DS2-VASc score as class I to predict the risk of ischemic stroke in patients with AF. However, the validity of the CHA2DS2-VASc and HAS-BLED scores to predict ischemic stroke and major bleeding events in patients without AF remains unclear.

B-po02-079 performance of atrial fibrillation burden patterns detected via insertable cardiac monitor for stroke risk stratification
Atrial fibrillation (AF) is associated with increased stroke risk, yet limitations in conventional monitoring restrict our understanding of AF burden risk thresholds. Predictive algorithms incorporating continuous monitoring data may be useful for stroke prediction.

B-po02-045 utility of a smartphone connected electrocardiogram recorder for detecting atrial fibrillation in post-stroke patients
Atrial fibrillation is one of the important causes of ischemic stroke. Routine 24-hour monitoring reveals latent atrial fibrillation in up to about 5% of cases. Despite the fact that today there are many ways to record heart rate, there is no precise algorithm that allows to detect atrial fibrillation in patients who have survived ischemic stroke of unknown etiology.

B-po01-028 utilization of cardiac monitoring for atrial fibrillation in cryptogenic stroke patients
Atrial fibrillation (AF) is found in ∼1/3 of cryptogenic stroke (CS) patients after long-term monitoring with an insertable cardiac monitor (ICM), enabling the use of anticoagulants for recurrent stroke prevention. However, little is known about monitoring pathways prior to ICM in this population.

Unequal prescription of anticoagulants among females and males with atrial fibrillation and similar stroke risk – should we omit sex category from the CHA2DS2-VASc score?
The CHA2DS2-VASc stroke risk score has been recommended by the European Society of Cardiology atrial fibrillation (AF) guidelines to guide decision on oral anticoagulation (OAC) prescription in AF patients. Whereas female sex was initially considered an individual risk factor warranting antithrombotic treatment in all female AF patients independent of other risk factors, this recommendation was revised as growing evidence showed that female sex is rather a risk modifier as sex does not contribute to stroke risk in the absence of other risk factors.

Po-716-07 is cha2ds2vasc score useful for predicting the risk of stroke in patients with atrial fibrillation and cancer? : a single-center observational analysis
Patients with active cancer were historically excluded from clinical trials validating the CHA2DS2VASc score for stroke prediction in atrial fibrillation (AF). Limited data have questioned the predictive value of the score in patients with cancer and AF, underscoring the need for more personalized scores for prediction of stroke in these patients.

Ce-543-03 early rhythm control in patients with incident atrial fibrillation who had a prior history of stroke: a nationwide population-based cohort study
Early rhythm control therapy has been demonstrated to be associated with a lower risk of stroke compared to usual care in patients with atrial fibrillation (AF). However, there are limited data regarding the benefit of early rhythm control therapy for secondary prevention for stroke in patients with AF.

Po-684-05 a cha ₂ds₂-vasc score of 2 and above predicts stroke risk in atrial flutter-a retrospective study from the national inpatient sample
The CHA ₂DS₂-VASc score is widely used to determine the stroke risk in atrial fibrillation (AF) patients. Although clinicians use the CHA₂DS₂-VASc score to determine the stroke risk in atrial flutter (AFL) patients, the use of the CHA₂DS₂-VASc score in AFL has not been well studied.

Po-625-05 electrocardiographic deep terminal negative of the p wave in v1 and ischemic stroke:the atherosclerosis risk in communities (aric) study
Abnormal P-wave indices are associated with ischemic stroke independent of atrial fibrillation (AF). Deep terminal negative of the P wave in V1 (DTNPV1) is a simple ECG index that reflects underlying left atrial remodeling. However, it is unknown whether DTNPV1 is associated with ischemic stroke.

Po-05-136 in stroke patients, do baseline electrocardiogram findings correlate with diagnostic findings on long-term monitoring with implantable loop recorder?
In patients with cryptogenic stroke, long-term monitoring is standard-of-care to exclude atrial tachyarrhythmias. Prior studies have not examined interatrial block (IAB) and other ECG markers paired with long-term continuous monitoring (the current gold standard) to predict likelihood of atrial fibrillation (AF) detection in stroke patients.

Po-01-071 risk of stroke in patients with atrial fibrillation undergoing catheter ablation compared to medical therapy: a meta-analysis of randomized controlled trials
Atrial fibrillation (AF) is a major risk factor for stroke. Although catheter ablation is associated with higher chance of sinus rhythm maintenance compared to medical therapy, the extent to which successful catheter ablation reduces stroke risk remains unclear.

Po-01-219 combination of early rhythm control and healthy lifestyle on the risk of stroke in elderly patients with new-onset atrial fibrillation: a korean nationwide population-based cohort study
Early rhythm control and lifestyle modification have both been associated with a lower risk of stroke in patients with atrial fibrillation (AF). However, the impact of early rhythm control strategy in combination with lifestyle modification on the risk of stroke is less clear in elderly population.

Po-01-210 stroke risk is identified by slow blood flow and stagnant blood particles in the left atrium
Atrial fibrillation (AF) is the most common type of arrhythmia, causing irregular contraction patterns in the atrial chambers. This rhythm disorder may result in stagnant flow, leading to the formation of blood clots, especially in the left atrial appendage (LAA), and causing a thrombotic stroke. Current stroke risk assessment in AF patients is done using CHADS2 or CHA2 DS2 –VASc scores, which are based on selected clinical characteristics, without accounting for potential risk factors such as LAA thrombi formation.

Ce-454029-4 racial disparities in the use of oral anticoagulation for atrial fibrillation by sex and within high and low stroke risk populations
Atrial fibrillation (AF) is the most common arrhythmia and is associated with an increased risk of ischemic stroke. Oral anticoagulation (OAC) has been shown to reduce the risk of ischemic stroke in patients with AF. Previous studies have demonstrated that both females and Black, Hispanic, and Asian groups are less likely to be prescribed OAC.

Admittance to detect alterations in left ventricular stroke volume
Implantable cardioverter-defibrillators monitor intracardiac electrocardiograms (EGMs) to discriminate between ventricular and supraventricular tachycardias. The incidence of inappropriate shocks remains high because of misclassification of the tachycardia in an otherwise hemodynamically stable individual. Coupling EGMs with an assessment of left ventricular (LV) stroke volume (SV) could help in gauging hemodynamics during an arrhythmia and reducing inappropriate shocks.
