Abstract

Background: There is preliminary evidence that early statin use may improve the outcomes of acute ischemic stroke patients following endovascular treatment.Methods: We analyzed data from subjects treated with intravenous (IV) recombinant tissue plasminogen activator (rt-PA) alone or in combination with endovascular treatment the Interventional Management of Stroke III trial. We compared the rates of functional independence (defined by modified Rankin scale of 0-2) and minimal impairment of activities of daily living (Barthel index at 90 days 95-100)at 3 and 12 months among subjects with ultra-early institution of statin treatment (on Day 0) with those in whom statin treatment was not initiated and in those in whom statins were initiated between Day 1-discharge (delayed institution)after adjusting for age and baseline National Institutes of Health Stroke Scale score strata, history of hyperlipidemia; and statin use at baselineResults: Of the 656 subjects who were recruited in the trial, ultra-early institution of statin treatment and delayed institution occurred in 51 and 387 subjects, respectively. At 3 months post randomization, the adjusted rates of independent functional outcome (odds ratio [OR] 2.3; 95 % confidence interval [CI] 1.2-4.5; P = 0.015) and minimal impairment of activities of daily living (OR 2.2; 95 % CI 1.1-4.3; P = 0.022) were higher among subjects with ultra-early institution of statin treatment compared with those without any statin treatment. The adjusted rates of functional independence (OR 2.7; 95 % CI 1.4-5.2; P = 0.004) continued to higher among subjects with ultra-early institution of statin treatment at 12 months post randomization. The adjusted rates of functional independence and minimal impairment of activities of daily living were higher among subjects with ultra-early institution of statin treatment compared with those without any statin treatment in subjects randomized to endovascular treatment.Conclusions: Ultra-early institution of statin treatment in acute ischemic stroke patients treated with IV rt-PA with or without endovascular treatment was associated with improved outcome at both 3 and 12 months
