Effect of statin treatment on clinical outcomes in cardioembolic stroke with endovascular thrombectomy

Abstract

Background While statins have been widely used in patients with large-artery atherosclerotic stroke, their effectiveness in patients with cardioembolic large vessel occlusion (CE-LVO) undergoing endovascular treatment (EVT) remains unclear. This study aimed to evaluate whether combining statin therapy with EVT could improve clinical outcomes in patients with acute ischemic stroke caused by CE-LVO in the anterior circulation.

Methods We performed a retrospective screening on patients with CE-LVO in the anterior circulation who underwent EVT in 27 hospitals across China between 2018 and 2021. The primary outcome measure was functional independence, defined as a 90-day modified Rankin Scale (mRS) score of 0 to 2. Safety outcomes included 90-day mortality and symptomatic intracranial hemorrhage (sICH).

Results A total of 510 patients with CE-LVO in the anterior circulation undergoing EVT were included in this study. Of these, 404 (79.2%) patients received statin treatment (statin group), while 106 (20.8%) did not (non-statin group). Statin treatment was significantly associated with improved functional independence (adjusted OR (aOR) 2.072, 95% CI 1.197 to 3.586, P=0.009). Moreover, statin use was associated with a lower rate of 90-day mortality (aOR 0.343, 95% CI 0.197 to 0.596, P<0.001) and a lower rate of sICH (aOR 0.153, 95% CI 0.072 to 0.325, P<0.001).

Conclusion Statin treatment was associated with improved clinical outcomes and reduced risks of mortality and sICH in patients with CE-LVO in the anterior circulation undergoing EVT.
