Bleeding, stroke, and mortality risk of patients with septic shock receiving anticoagulation for atrial fibrillation.
Background: There are limited data on the effects of therapeutic anticoagulation (AC) on stroke and bleeding risk in patients with sepsis-induced atrial fibrillation (AF).
Objective: This study aimed to determine the effect of therapeutic AC on the development of inpatient strokes and significant bleeding in hospitalized patients with septic shock and AF.
Methods: This single-center, retrospective study examined 604 patients with septic shock and AF. The total AF population was further subdivided into new-onset AF. Propensity score matching was used to match patients with similar comorbidities who received and did not receive AC. The risks of bleeding, in-hospital stroke, increased length of stay, and mortality were compared between propensity score-matched cohorts.
Results: Bleeding Academic Research Consortium 2 and 3a bleeding events were the most common. After propensity score matching, the relative risk of bleeding on AC was not significantly higher in either group (AF, 1.33 [95% confidence interval, 0.81-2.17]; new-onset AF, 1.60 [95% confidence interval, 0.72-3.54]). AC also did not decrease the number of ischemic strokes (AF, 1.34% with AC vs 1.34% without AC [P = 1]; new-onset AF, 0.89% with AC vs 1.79% without AC [P = .56]). There was significantly reduced mortality of patients who received AC (AF, 52.35% with AC vs 66.44% without AC [P = .01]; new-onset AF, 46.43% with AC vs 66.07% without AC [P = .04]).
Conclusion: In patients with septic shock and AF, AC was not associated with a higher incidence of bleeding or lowering of in-hospital strokes but was associated with decreased mortality, potentially protecting against disseminated intravascular coagulopathy or other embolic phenomena.
