Clinical Report: The Impact of Aspirin on Clinical Outcomes in Sepsis Patients with Atrial Fibrillation
Overview
This study evaluates the association between early aspirin exposure and mortality in sepsis patients with atrial fibrillation (AF).
Background
Sepsis is a critical condition characterized by a dysregulated inflammatory response to infection, leading to significant morbidity and mortality. Atrial fibrillation (AF) is a common complication in sepsis, which can exacerbate hemodynamic instability and worsen clinical outcomes. The role of aspirin in improving outcomes for sepsis patients with AF is not well established.

Key Findings
Early aspirin exposure was associated with lower 30-day all-cause mortality in sepsis patients with AF.
The hazard ratio for 30-day mortality in the fully adjusted model was 0.624 (95% CI: 0.547–0.712; P < 0.001).
In overlap-weighted analysis, the association remained significant with an HR of 0.738 (95% CI: 0.647–0.842; P < 0.001).
Newly initiated aspirin within 48 hours after ICU admission showed a significant inverse association with mortality.
In eICU-CRD, early aspirin exposure was linked to lower in-hospital mortality (HR: 0.732, 95% CI: 0.559–0.959; P = 0.024).
Clinical Implications
The findings suggest that early aspirin administration may be beneficial for sepsis patients with AF, particularly for those newly started on aspirin in the ICU setting. Clinicians should consider the timing of aspirin exposure when evaluating treatment strategies for this patient population.
Conclusion
Further research is warranted to clarify the role of aspirin in this clinical scenario.
Invited narrative review supports early, interprofessional rehabilitation across the ICU recovery continuum while emphasizing heterogeneous evidence and inconsistent implementation worldwide.
