Background And Objective: Treating recurrent atrial arrhythmias after persistent atrial fibrillation (PeAF) ablation is often challenging. This single-center, prospective study aimed to observe the effectiveness of different combinations of oral antiarrhythmic drugs (AADs) in reverting to sinus rhythm (SR) in patients with recurrent atrial arrhythmias after PeAF ablation.
Methods: Forty-five patients who experienced recurrent atrial arrhythmias after PeAF ablation were included. Based on their medication regimens, patients were divided into two groups, with the study group being a triple-drug group (digoxin combined with amiodarone/ propafenone and β-blocker), and the control group being a non-triple-drug group.
Results: The rate of reversion to SR was significantly higher in the study group (n = 29) than in the control group (n = 16) at 3 weeks (34.48% vs. 0%, p < 0.01) and 1 month (44.84% vs. 6.25%, p = 0.02) after initiating AADs. No patients with asymptomatic bradycardia were observed in either group.
Conclusions: For patients with recurrent atrial arrhythmias after PeAF ablation, a regimen of low-dose digoxin combined with amiodarone/propafenone and β-blocker may effectively improve short-term reversion rates.

AF-FLOW Global Registry Confirms Validity of Electrographic Flow Mapping as a Phenotyping Tool for Atrial Fibrillation.

Background: Electrographic flow (EGF) mapping allows for the visualization of global atrial wavefront propagations. One mechanism of initiation and maintenance of atrial fibrillation (AF) is stimulation from EGF-identified focal sources that serve as driver sites of fibrillatory conduction. Electrographic flow consistency (EGFC) further quantifies the concordance of observed wavefront patterns, indicating that a healthier substrate shows more organized wavefront propagation and higher EGFC.

The impact of the number of stroke episodes on the natural history of patients with AF is still unclear.
Methods And Results: Using data from the international, multicenter, and prospective GLORIA-AF (Global Registry on Long-Term Oral Antithrombotic Treatment in Patients With Atrial Fibrillation) Registry Phase III, we categorized patients with a recent diagnosis of non-valvular AF according to the number of previous strokes (either 0, 1, or ≥2 episodes).
Associations of Social, Behavioral, and Clinical Factors With Sex Differences in Stroke Recurrence and Poststroke Mortality.

Background: Few population-based studies have assessed sex differences in stroke recurrence. In addition, contributors to sex differences in recurrence and poststroke mortality, including social factors, are unclear. We investigated sex differences in these outcomes and the contribution of social, clinical, and behavioral factors to the sex differences.

However, the impact of malnutrition on the clinical outcomes for patients undergoing catheter ablation for AF is still debated. Our study aimed to examine this relationship using all existing available data.
