AF-B-STEP: a global collaboration to reduce the burden of atrial fibrillation and advance its quantification and treatment
Obergassel J, de Melis M, and Kirchhof P (2026), European Heart Journal, 47(31): pp. 4185–4187Further readingCurrently, atrial fibrillation (AF) is still largely treated as a binary diagnosis, overlooking the wide range of episode patterns and intensities. More precise, quantitative measures of AF burden are therefore needed to better understand disease progression, assess risk and enable more personalised treatment and management.

Calibration and clarification: atrial fibrillation burden estimated by ECG patch recordings
Tesfamariam M and Kirchhof P (2026), Heart (online ahead of print)Further readingAtrial fibrillation (AF) is traditionally diagnosed as a binary condition, but growing evidence suggests that AF burden - the proportion of time a person spends in AF - may provide important additional clinical information. Large-scale rhythm-monitoring data highlight substantial variation in AF burden and support its potential role in refining cardiovascular risk assessment and guiding treatment. Further research, including the AF-B-STEP project, will investigate how AF burden can better inform screening, treatment and health policy.

Interactions of blood biomolecules with early rhythm control in atrial fibrillation patients: exploratory analysis of the EAST-AFNET 4 biomolecule study
Al-Taie C et al. (2026), EP Europace, 28(7): euag149Further readingEarly rhythm control (ERC) reduces cardiovascular events in patients with atrial fibrillation (AF), but whether its benefits vary with the severity of AF-associated conditions is unclear. In the EAST-AFNET 4 biomolecule study, 14 circulating biomarkers were analysed in 1,586 patients. ERC reduced cardiovascular outcomes consistently across biomarker concentrations, with no evidence of treatment interaction for 13 of 14 biomarkers. A potentially attenuated benefit in patients with low BMP10 concentrations was observed in exploratory analyses and warrants further investigation.

Kidney disease increases the risk of cardiovascular events in patients with device-detected atrial fibrillation: NOAH-AFNET 6
Goette A et al. (2026), EP Europace, 28(4): euag083Further readingA prespecified analysis of the NOAH-AFNET 6 trial shows that impaired kidney function is associated with a higher risk of cardiovascular events in patients with device-detected atrial fibrillation. Age and estimated glomerular filtration rate (eGFR) were among the strongest predictors of cardiovascular events, particularly cardiovascular death, suggesting that eGFR may help refine risk assessment in this patient population.

Pre-procedural time spent in atrial fibrillation using intermittent ECG monitoring is associated with arrhythmia recurrence after ablation: the ISOLATION cohort study
Habibi Z et al. (2026), Europace, 28 (3): euag044Atrial fibrillation (AF) burden may provide a more precise picture of treatment response than conventional AF classification. In this study, the percentage of time patients spent in AF before ablation independently predicted arrhythmia recurrence. Notably, patients classified as having paroxysmal AF but with a high AF burden had recurrence rates similar to those with persistent AF, highlighting the potential of quantitative AF burden measures to improve risk assessment and personalise treatment.Further reading
