Key result

A combined risk score predicts new-onset AF, with frequent PACs linked to ~208% higher risk.

Key Points

To review emerging diagnostic and therapeutic approaches for atrial fibrillation, emphasizing the contribution of chronic inflammation, predictive biomarkers, and advanced ablation modalities.
Synthesized clinical and preclinical evidence examining the role of systemic and localized chronic inflammation in the pathogenesis of atrial fibrillation.
Evaluated novel biomarkers, including pentraxin 3, interleukin-6, and circulating cell-free DNA, alongside artificial intelligence models for predicting arrhythmia onset.
Reviewed therapeutic interventions addressing factor Xa–protease-activated receptor-2 signaling pathways and catheter-based interventions such as pulse field ablation.
Chronic inflammation directly participates in arrhythmia pathogenesis, evidenced by increased atrial inflammatory cell infiltration and elevated circulating levels of C-reactive protein and interleukin-6.
Pentraxin 3 concentrations were significantly elevated in the left atrial appendage compared to the peripheral circulation in patients with atrial fibrillation, whereas control patients displayed no significant chamber-specific gradient.
Targeted inhibition of factor Xa–protease-activated receptor-2 signaling and novel rhythm-control modalities, including pulse field ablation, offer promising strategies to treat atrial fibrillation complicated by heart failure.

P

Population

Atrial fibrillation

Chronic inflammation and the factor Xa-PAR-2 pathway represent promising new avenues for the diagnosis and targeted treatment of atrial fibrillation.

Limitations

Novel biomarkers like PTX3 and microRNAs face clinical application challenges including high costs, technical variability, and a lack of standardized protocols.
Cell-free DNA results vary significantly depending on the extraction and quantification method, making disease specificity problematic.
Findings regarding factor Xa-PAR2 signaling and the preventive effects of rivaroxaban on atrial remodeling are based on animal studies and require rigorous clinical validation.

Abstract

Atrial fibrillation (AF) is a prevalent arrhythmia that exhibits an increased incidence with advancing age. AF has emerged as a critical public health concern due to its potential to precipitate cerebral infarction and heart failure. Therefore, it is imperative to implement preventive strategies for individuals at risk of AF, enable earlier diagnoses, and ensure reliable therapeutic interventions. Despite rapid advancements in diagnostic and therapeutic tools for AF, these remain insufficient. Recent studies have focused on developing diagnostic and therapeutic methodologies for AF, particularly regarding chronic inflammation. Clinical investigations have explored biomarkers of AF associated with various pathologies, including chronic inflammation, such as circulating pentraxin 3, microRNA, and fragmented cell-free DNA. Several studies have examined novel indicators that integrate conventional risk factors or the use of artificial intelligence to predict the onset of AF. We explore emerging therapeutic strategies for AF, focusing on the potential to inhibit its onset and progression by targeting factor Xa - protease-activated receptor-2 signaling. Additionally, we review the treatment of AF complicated by heart failure through catheter ablation, including the innovative technique of pulse field ablation. This review focuses on the advancement of innovative diagnostic and therapeutic strategies for AF through a multifaceted approach. J. Med. Invest. 73 : 1-11, February, 2026.
