Association between new-onset atrial fibrillation and adverse clinical outcomes by country of origin: A matched nationwide cohort study.

ABSTRACT:

Background

Incidence and prevalence of atrial fibrillation (AF) is increasing worldwide, and the condition is associated with high risk of adverse clinical outcomes. Increasing global migration results in more diverse patient populations, and knowledge about AF-related outcomes in immigrants is warranted.

Patients with first-time AF and sex-, age- and country of origin matched non-AF population (ratio 1:5) were followed from age 45 from 1998 to 2017.
