Abstract :Aims: Recent studies have demonstrated an association between uric acid (UA) albumin ratio (UAR), and newly developing atrial fibrillation (AF) and also AF recurrence. We conducted a study to examine the prognostic value of UAR in critically ill patients with AF. Methods: A retrospective examination was conducted on patients diagnosed with AF based on electrocardiography, who admitted to the intensive care unit (ICU) from the emergency department during the period from January 1st to May 1st, 2024. UAR levels were calculated by dividing the amount of UA by the amount of albumin. Based on the cut-off value, UAR levels were categorized into two groups: low UAR and high UAR. A comprehensive comparison was conducted on all the data between these two groups. Results: The high UAR (UAR>0.231) group exhibited significantly higher UA, vasopressor requirement, mechanical ventilation support, length of stay in ICU, and in-hospital mortality rate compared to the low UAR (UAR≤0.231) group. Conversely, albumin levels were significantly lower (p<0.001 for all). The UAR cut-off value was 0.231, with a sensitivity of 97.3% and a specificity of 96.7% (The area under the curve (AUC):0.995, p<0.001). The mortality prediction ability of UAR was superior to that of albumin and UA alone (AUC: 0.995, 0.956, 0.981, respectively). Conclusion: UAR is a cost-effective, easily accessible, useful marker for assessing the prognosis of critically ill patients with AF in ICU.
