Abstract

<h4>Background and purpose</h4>The impact of bridging thrombolysis prior to endovascular thrombectomy (EVT) compared to EVT alone on intracerebral haemorrhage (ICH), subarachnoid haemorrhage (SAH), and death in anticoagulated atrial fibrillation (AF) patients with acute ischaemic stroke (AIS) is not well defined.<h4>Methods</h4>A retrospective study was conducted using data from a federated research network (TriNetX) including 114 health care organisations in the United States. Anticoagulated AF patients with AIS who received either bridging thrombolysis (BT) or EVT alone from September 2018 to November 2023 were included. Following propensity score matching, Cox regression analyses examined the risk of ICH, SAH, and death within 30 and 90 days, comparing anticoagulated AF patients receiving BT versus EVT only.<h4>Results</h4>A total of 3156 patients with AIS were treated with BT or EVT alone. Following 1:1 propensity score matching, the cohort included 766 patients in each group. ICH occurred within 30 and 90 days in 6.9% and 8.0% in the BT group compared with 7.4% and 7.7% in the EVT-only group (hazard ratios [HR] = 0.92, 95% confidence interval [CI] = 0.63-1.33 and HR = 1.01, 95% CI = 0.71-1.45, respectively). SAH occurred within 30 and 90 days in 4.2% and 4.4% of patients in the BT compared to 3.0% and 3.4% in the EVT-only group (HR = 1.38, 95% CI = 0.81-2.38 and HR = 1.29, 95% CI = 0.77-2.14, respectively). Death occurred within 30 and 90 days in 17.8% and 19.8% of patients in the BT compared to 22.2% and 27.3% in the EVT-only group (HR = 0.77, 95% CI = 0.62-0.97 and HR = 0.65, 95% CI = 0.56-0.86, respectively).<h4>Conclusions</h4>In anticoagulated AF patients with AIS, BT was associated with a significantly lower risk of death, with no difference in ICH or SAH risk within 30 and 90 days compared to EVT only.
