OBJECTIVE: To examine whether serum cholesterol levels have any prognostic value in the first month following acute ischemic stroke. BACKGROUND: Although the association between serum cholesterol levels and cerebrovascular disorders has been extensively studied, the relationship between cholesterol levels and outcome following ischemic stroke has not been investigated. METHODS: Using data from 3,273 consecutive patients with first-ever ischemic stroke, the authors compared poor functional outcome (severe disability or death) at 1 month in patients with high cholesterol (total serum cholesterol greater than 6.5 mmol/L or 250 mg/dL) and normal cholesterol (level equal to or less than 6.5 mmol/L or 250 mg/dL). Data were analyzed by univariate and multivariate analysis. RESULTS: In comparison with patients with normal cholesterol levels, patients with high cholesterol levels had a 2.2-fold lower risk of death (p = 0.002) and a 2.1-fold lower risk of poor functional outcome at 1 month (p < 0.001). After adjustment for known confounding variables, multivariate analysis showed that higher cholesterol levels remained an independent predictor of better functional outcome (OR 0.48, CI 0. 34 to 0.69, p < 0.001). CONCLUSIONS: The authors' findings suggest that higher levels of cholesterol are associated with a better outcome in the early phase after ischemic stroke.
