Outcomes in patients with ischaemic stroke undergoing endovascular thrombectomy: impact of atrial fibrillation

Abstract Background/Introduction Endovascular thrombectomy (EVT) has become the standard of care for management acute ischaemic stroke, but risk intracerebral haemorrhage and mortality still remains common following stroke. The effect concomitant atrial fibrillation (AF) on clinical outcomes in patients with stroke after receiving EVT unclear. Purpose To investigate associations between AF (ICH) all-cause at 90 days undergoing EVT. Methods A retrospective cohort was conducted using TriNetX, a global health research network. network searched people aged ≥18 years recorded electronic medical records 01/09/2018 01/09/2021. These were compared to controls no AF. Propensity score matching age, sex, race, comorbidities, National Institutes Health Stroke Scale (NIHSS) scores, prior use anticoagulation used balance cohorts without Results In total 1,388 identified history treated by After propensity-score matching, 832 (mean age 68±13; 47% female) AF, 67±12; 11.5% (n=96) experienced ICH within EVT, 12.3% (n=103 patients) (Odds Ratio (OR) 0.92, 95% confidence interval (CI) 0.68–1.24; p=0.59). 18.7% (n=156), 22.5% (n=187) (OR 0.79, CI 0.63–1.01; p=0.06). Conclusion not significantly associated or 90-day follow-up. Funding Acknowledgement Type funding sources: Private grant(s) and/or Sponsorship.
