Statin Use

Background: Statin therapy has been shown to be effective in the prevention of ischemic stroke. In addition, recent studies have suggested that prior statin therapy could lower the initial stroke severity and improve stroke functional outcomes in the event of stroke. It was speculated that prestroke statin use may enhance collateral circulation and result in favorable functional outcomes. Objective: The aim of the study was to investigate the association of prestroke statin use with leptomeningeal collaterals and to determine the association of prestroke statin use with stroke severity and functional outcome in acute ischemic stroke patients. Methods: We prospectively and consecutively enrolled 239 acute ischemic stroke patients with acute infarction due to occlusion of the middle cerebral artery within 24 h in the neurology department of West China Hospital from May 2011 to April 2017. Computed tomographic angiography (CTA) imaging was performed for all patients to detect middle cerebral artery thrombus; regional leptomeningeal collateral score (rLMCS) was used to assess the degree of collateral circulation; the National Institutes of Health Stroke Scale (NIHSS) was used to measure stroke severity at admission; the modified Rankin scale (mRS) was used to measure outcome at 90 days; and premorbid medications were recorded. Univariate and multivariate analyses were performed. Results: Overall, 239 patients met the inclusion criteria. Fifty-four patients used statins, and 185 did not use statins before stroke onset. Prestroke statin use was independently associated with good collateral circulation (rLMCS > 10) (odds ratio [OR], 4.786; 95% confidence interval [CI], 1.195–19.171; P = 0.027). Prestroke statin use was not independently associated with lower stroke severity (NIHSS score≤14) (OR, 1.955; 95% CI, 0.657–5.816; p = 0.228), but prestroke statin use was independently associated with favorable outcome (mRS score≤2) (OR, 3.868; 95% CI, 1.325–11.289; P = 0.013). Conclusions: Our findings suggest that prestroke statin use was associated with good leptomeningeal collaterals and clinical outcomes in acute ischemic stroke (AIS) patients presenting with occlusion of the middle cerebral artery. However, clinical studies should be conducted to verify this claim.
