Atrial fibrillation is associated with poor long-term outcome after mechanical thrombectomy for anterior large vessel occlusion stroke

Atrial fibrillation (AF) is one of the leading causes of acute ischemic stroke (AIS). The aim of our study was to determine the influence of AF on the long-term outcome of patients with AIS due to anterior circulation large vessel occlusion (LVO) treated with mechanical thrombectomy (MT). Our study included 127 consecutive patients with AIS due to anterior LVO who underwent MT between January 2018 and March 2020. Demographics, clinical, radiological and treatment characteristics were prospectively collected. Modified Rankin scale (mRS) score ≤2 was defined as a good functional outcome. AF was detected in 62 (48.8%) patients. Patients with AF were elder (73.1 ± 8.7 vs. 58.5 ± 14.2 years, p
