Low-Dose Rivaroxaban Fails to Halt Cognitive Decline in Low-Risk Atrial Fibrillation: Results from the BRAIN-AF Trial

Low-Dose Rivaroxaban Fails to Halt Cognitive Decline in Low-Risk Atrial Fibrillation: Results from the BRAIN-AF Trial

The multicenter BRAIN-AF trial found that rivaroxaban did not prevent cognitive decline or stroke in patients with atrial fibrillation and low CHA2DS2-VASc scores. Despite significant cognitive deterioration observed across both groups, the trial was halted early for futility, highlighting the complexity of AF-related neurocognitive impairment.
Genetic Risk Profile Predicts Stroke Prevention Benefit From Continuous Atrial Fibrillation Screening: A Secondary Analysis of the LOOP Study

Genetic Risk Profile Predicts Stroke Prevention Benefit From Continuous Atrial Fibrillation Screening: A Secondary Analysis of the LOOP Study

A secondary analysis of the LOOP study demonstrates that continuous ECG screening with implantable loop recorders significantly reduces stroke and systemic embolism in individuals with high genetic risk for atrial fibrillation, while potentially increasing bleeding risk in lower-risk cohorts.
Proteomic Signatures in Atrial Fibrillation: Deciphering the Risk of Heart Failure Hospitalization and Ejection Fraction Phenotypes

Proteomic Signatures in Atrial Fibrillation: Deciphering the Risk of Heart Failure Hospitalization and Ejection Fraction Phenotypes

This study identifies key plasma biomarkers—including NT-proBNP, FGF-23, and GDF-15—that predict heart failure hospitalization in patients with atrial fibrillation. Findings also reveal distinct pathophysiological pathways for HFrEF and HFpEF, highlighting the roles of inflammation and adipose metabolism.
Rethinking Rhythm Management: Catheter Ablation Outperforms Medical Therapy in Atrial Fibrillation Patients with High Comorbidity Burden

Rethinking Rhythm Management: Catheter Ablation Outperforms Medical Therapy in Atrial Fibrillation Patients with High Comorbidity Burden

A post hoc analysis of the CABANA trial reveals that catheter ablation significantly reduces major cardiovascular events and improves quality of life in AF patients with high comorbidity burden (≥4 conditions), suggesting that multimorbidity should not be a barrier to invasive rhythm control strategies.
Predicting Stroke Recurrence: MRI Markers Outperform Location in Risk-Stratifying Patients with ICH and Atrial Fibrillation

Predicting Stroke Recurrence: MRI Markers Outperform Location in Risk-Stratifying Patients with ICH and Atrial Fibrillation

A secondary analysis of the PRESTIGE-AF trial reveals that specific MRI markers, including cortical superficial siderosis and macrohemorrhages, are more potent predictors of recurrent intracerebral hemorrhage than hematoma location alone, offering a path toward individualized anticoagulation strategies.
Precision Medicine in Atrial Fibrillation: Biomarker-Based ABC-AF Risk Scores Fail to Outperform Standard Care

Precision Medicine in Atrial Fibrillation: Biomarker-Based ABC-AF Risk Scores Fail to Outperform Standard Care

A large-scale registry-based RCT reveals that tailoring atrial fibrillation treatment using the biomarker-driven ABC-AF risk score does not significantly reduce stroke or death compared to current standard guideline-based care, highlighting the complexities of implementing precision medicine in clinical practice.
