Article Abstract
Background And Aims: In patients with atrial fibrillation (AF), recurrent AF and sinus rhythm during follow-up are determined by interactions between cardiovascular disease processes and rhythm control therapy. Predictors of attaining sinus rhythm at follow-up are not well known.
Methods: To quantify the interaction between cardiovascular disease processes and rhythm outcomes, 14 biomarkers reflecting AF-related cardiovascular disease processes in 1586 patients in the EAST-AFNET 4 biomolecule study (71 years old, 45% women) were quantified at baseline. Mixed logistic regression models including clinical features were constructed for each biomarker. Biomarkers were interrogated for interaction with early rhythm control. Outcome was sinus rhythm at 12 months. Results were validated at 24 months and in external datasets.
Results: Higher baseline concentrations of three biomarkers were independently associated with a lower chance of sinus rhythm at 12 months: angiopoietin 2 (ANGPT2) (odds ratio [OR] .76 [95% confidence interval .65-.89], P < .001), bone morphogenetic protein 10 (BMP10) (OR .83 [.71-.97], P = .017), and N-terminal pro-B-type natriuretic peptide (NT-proBNP) (OR .73 [.60-.88], P < .001). Analysis of rhythm at 24 months confirmed the results. Early rhythm control interacted with the predictive potential of NT-proBNP (Pinteraction = .033). The predictive effect of NT-proBNP was reduced in patients randomized to early rhythm control (usual care: OR .64 [.51-.80], P < .001; early rhythm control: OR .90 [.69-1.18], P = .453). External validation confirmed that low concentrations of ANGPT2, BMP10, and NT-proBNP predict sinus rhythm during follow-up.
Conclusions: Low concentrations of ANGPT2, BMP10, and NT-proBNP identify patients with AF who are likely to attain sinus rhythm during follow-up. The predictive ability of NT-proBNP is attenuated in patients receiving rhythm control.

Baricitinib Combination Therapy Demonstrates Significant Improvement in Cardiac Conduction Defects in Rapidly Progressive Systemic Sclerosis: A Case Report.
Open Access Rheumatol
August 2025
Department of Rheumatology and Immunology, the First Affiliated Hospital, Jinan University, Guangzhou, 510632, People's Republic of China.
Objective: To evaluate the efficacy of baricitinib in combination therapy for managing refractory, rapidly progressive systemic sclerosis (SSc) with severe cardiac conduction defects and interstitial lung disease (ILD).
Methods: A 48-year-old male patient with SSc complicated by significant cardiac enlargement, third-degree atrioventricular block, heart failure, progressive ILD, and partial intestinal obstruction was included in the study. Prior treatments with mycophenolate mofetil (MMF), tacrolimus, and cyclophosphamide (CTX) had shown limited efficacy.

Division of Cardiology, Tokyo Metropolitan Ohkubo Hospital, Shinjyuku-ku, Tokyo, Japan.
Background: Various methods have been devised for catheter ablation of persistent atrial fibrillation (AF). However, it remains difficult to understand the mechanism of AF and to determine the optimal method.
Objective: This study aimed to evaluate the effectiveness of rotor modification (RM) compared to posterior wall isolation (PWI) in the treatment of persistent AF.

Heart Rhythm O2
August 2025
Department of Electrophysiology, TUM University Hospital German Heart Center, Munich, Germany.
Background: Data on atrial fibrillation (AF) ablation using high-power short-duration (HPSD) ablation in patients over 80 years are lacking.
Objective: This study aimed to compare the safety and efficacy of paroxysmal and persistent AF ablation using an HPSD (60-90 W/4-8 sec) vs conventional ablation (30-40 W/30 sec) in a propensity score-matched cohort of patients older than 80 years.
Methods: Overall, 232 consecutive patients aged over 80 years undergoing AF ablation were included.
How Often is Multifocal Atrial Tachycardia Mistaken for Atrial Fibrillation in the Emergency Department?
Am J Med Sci

The Ruth and Bruce Rappaport Faculty of Medicine, Technion, Israel Institute of Technology, Haifa, Israel; Department of Internal Medicine, Lady Davis Carmel Medical Center, Haifa, Israel.
Objective: Multifocal atrial tachycardia (MAT), characterized by an irregularly irregular rhythm, is often regarded as a clinical imitator of atrial fibrillation (AF). We aimed to evaluate the prevalence of MAT misclassification as AF in the emergency department (ED) setting.
Methods: A retrospective analysis of 1,828 ECGs from patients discharged with AF diagnoses over five years.
