Abstract

Background:  New-onset atrial fibrillation (AF) often develops in critically ill patients, yet data from Emergency Department (ED) populations remain scarce. We aimed to measure the frequency of new-onset AF in critically ill ED patients and examine its association with short-term outcomes.

Methods:  We carried out a cross-sectional study of 137 critically ill patients presenting to a tertiary care ED. For each patient, we recorded demographic details, AF status, need for hospital admission, stroke, and ED mortality. We compared outcomes between patients with and without AF using chi-square tests, with p<0.05 indicating statistical significance.

Results:  New-onset AF occurred in 26 patients (19%). Most AF cases were in patients aged 46–70 years (72.7%). AF showed no significant association with sex (p=0.31) or stroke (p=0.84). Patients with AF were more likely to be admitted than those without AF (57.7% vs. 43.2%, p=0.18), though this was not significant. Mortality in the ED was markedly higher among AF patients (46.2%) compared with those without AF (12.6%, p=0.01).

Conclusion:  New-onset AF was frequent in critically ill ED patients and carried a substantially higher risk of early death. Stroke rates were similar between AF and non-AF groups. Clinicians should identify AF promptly and monitor these patients closely.
