In addition to their lipid-lowering effects, it has been speculated that statins may also have beneficial effects on cerebral circulation and brain parenchyma during ischaemic stroke and reperfusion. We hypothesized that patients who had taken statins prior to stroke onset may have a better survival rate at 1 month and during the follow-up period. We retrospectively studied consecutive ischaemic stroke patients admitted to an acute stroke unit and at least a month's follow-up. From these, we included those patients who, at admission, had reported the use of a statin prior to the stroke onset in the statin group (n = 205). Each patient in the statin group was matched with two patients who reported no statin use (n = 410). Using logistic regression and Cox proportional hazards models, we adjusted for variables that significantly differed between treatment groups or that independently predicted mortality. After adjusting for those variables, statin use was associated with reduced mortality at 1 month [odds ratio 0.24; 95% confidence interval (CI) 0.09-0.67] and during the follow-up period (hazard ratio 0.57; 95% CI 0.35-0.93). The use of statins prior to stroke onset is associated with improved stroke survival within this cohort study with matched controls.
除了具有降脂作用外,据推测他汀类药物在缺血性卒中和再灌注期间可能对脑循环和脑实质也有有益影响。我们假设在卒中发作前服用他汀类药物的患者在1个月及随访期间可能有更高的生存率。我们对入住急性卒中单元且至少随访1个月的连续性缺血性卒中患者进行了回顾性研究。从中,我们纳入了他汀类药物组中那些在入院时报告在卒中发作前使用过他汀类药物的患者(n = 205)。他汀类药物组的每位患者与两名报告未使用他汀类药物的患者进行匹配(n = 410)。使用逻辑回归和Cox比例风险模型,我们对治疗组之间有显著差异或独立预测死亡率的变量进行了调整。在对这些变量进行调整后,使用他汀类药物与1个月时死亡率降低相关[比值比0.24;95%置信区间(CI)0.09 - 0.67]以及随访期间(风险比0.57;95% CI 0.35 - 0.93)。在这项有匹配对照的队列研究中,卒中发作前使用他汀类药物与改善卒中生存率相关。
