Abstract/OtherAbstract:
Although statin therapy has been shown to be effective in the prevention of ischemic stroke, its effect on stroke severity and early outcome is still controversial. We aimed to evaluate the association between statin use before onset and both initial severity and functional outcome in ischemic stroke patients. All cases of first-ever ischemic stroke that occurred in Dijon, France (151,000 inhabitants) between 2006 and 2011 were prospectively identified from the Dijon Stroke Registry. Vascular risk factors, clinical severity at onset assessed by the NIHSS score, stroke subtypes, prestroke statin use, and lipid profile were collected. Functional outcome was defined by a six-level categorical outcome using the modified Rankin scale. Analyses were performed using ordinal logistic regression models. Among the 953 patients with first-ever ischemic stroke, 127 (13.3 %) had previously been treated with statins. Initial stroke severity did not differ between statin users and non-users [median NIHSS score (interquartile range) 4.0 (7.0) versus 4.0 (9.0) p = 0.104]. In unadjusted analysis, statin use was associated with a lower risk of an unfavorable functional outcome at discharge (OR 0.69; 95 % CI 0.49-0.96; p = 0.026) that was no longer significant in multivariate analyses (OR 0.76; 95 % CI 0.53-1.09; p = 0.134). After adjustment for admission plasma LDL cholesterol levels, the non-significant association was still observed (OR 0.76; 95 % CI 0.49-1.18; p = 0.221). This population-based study showed that prestroke statin therapy did not affect initial clinical severity but was associated with a non-significant better early functional outcome after ischemic stroke.
