BACKGROUND AND PURPOSE: Statins may be beneficial for patients with acute ischemic stroke. We tested the hypothesis that patients pretreated with statins at the onset of stroke have less severe neurological effects and a better outcome. METHODS: We prospectively included consecutive patients with ischemic stroke of <24-hour duration. We recorded demographic data, vascular risk factors, Oxfordshire Classification, National Institutes of Health Stroke Scale (NIHSS) score, admission blood glucose and body temperature, cause (Trial of Org 10172 in Acute Treatment [TOAST] criteria), neurological progression at day 3, previous statin treatment, and outcome at 3 months. We analyzed the data using univariate methods and a logistic regression with the dependent variable of good outcome (modified Rankin Scale [mRS] 0 to 1, Barthel Index [BI] 95 to 100). RESULTS: We included 167 patients (mean age 70.7+/-12 years, 94 men). Thirty patients (18%) were using statins when admitted. In the statin group, the median NIHSS score was not significantly lower and the risk of progression was not significantly reduced. Favorable outcomes at 3 months were more frequent in the statin group (80% versus 61.3%, P=0.059 with the mRS; 76.7% versus 51.8%, P=0.015 with the BI). Predictors of favorable outcome with the BI were: NIHSS score at admission (OR: 0.72; CI: 0.65 to 0.80; P<0.0001), age (OR: 0.96; CI: 0.92 to 0.99; P=0.017), and statin group (OR: 5.55; CI: 1.42 to 17.8; P=0.012). CONCLUSIONS: Statins may provide benefits for the long-term functional outcome when administered before the onset of cerebral ischemia. However, randomized controlled trials will be required to evaluate the validity of our results.
