摘要：Aneurysmal subarachnoid hemorrhage (aSAH)-induced cerebral vasospasm and delayed ischemic neurological deficit (DIND) are the major causes of morbidity and mortality in patients with aSAH. The effects of statins-use for patients with aSAH remain controversial. Here,a total of 249 patients from six randomized controlled trials(RCTs) were subjected to meta-analysis. No significant decrease was found in the incidence of vasospasm(RR, 0.80; 95% CI, 0.54–1.17), with substantial heterogeneity (I2 = 49%, P = 0.08), which was verified by the further sensitivity analysis and subgroup meta-analysis. Furthermore, no significant difference was presented in the incidence of poor neurological outcome(RR, 0.94; 95% CI, 0.77–1.16), and potential side effects(RR, 2.49; 95% CI, 0.75–8.33). Nevertheless, significant difference was reported in the occurrence of DIND(RR, 0.58; 95% CI, 0.37–0.92) and mortality(RR, 0.30; 95% CI, 0.14–0.64). At present, although statins-use in the patients with aSAH should not be considered standard care at present, statins-use may have the potential effects in the prevention of mortality in patients with aSAH.
