Key result
ECG and echo abnormalities are linked to AF development in a large Brazilian cohort.
Why the study?
Atrial fibrillation presents significant variability in epidemiology, clinical presentation, risk factors, access to treatment, and prognosis, making the understanding of regional, social, and ethnic variations of paramount importance.
Informs regional AF burden estimates; hypothesis-generating for ECG/echo associations, needing prospective validation before practice implications.

Issa et al. (2025) conducted an editorial in Atrial Fibrillation (n=15,105). Electrocardiographic and echocardiographic parameters was evaluated on Occurrence of atrial fibrillation. In the ELSA-Brasil cohort of 15,105 civil servants, the prevalence of atrial fibrillation was 4.2%, and several electrocardiographic and echocardiographic parameters were associated with its development.
