Studies have reported that statin usage before stroke can increase the incidence of intracerebral hemorrhage after thrombolytic treatment. However, whether the administration of statin at an early stage of ischemic stroke increases hemorrhage occurrence is unknown. The aim of this study was to assess the effect of statin on neurological imaging and functional outcomes after intravenous alteplase treatment, within 24 h of acute ischemic stroke attack. A total of 119 consecutive acute ischemic stroke patients treated by intravenous alteplase were recruited, of which 71 patients (59.7 %) were given statin therapy within 24 h of stroke onset. The physiological parameters, including demography, vascular risk factors, and clinical characteristics were recorded. The occurrence of intracerebral hemorrhage (ICH), symptomatic intracerebral hemorrhage (sICH), 90-day functional outcomes, and mortality in the patients were further analyzed. There were 24 occurrences of ICH after alteplase treatment (20.2 %) and there was no difference when patients were treated with statin (p = 0.280). Multivariate logistic regression analysis showed no significant correlation between the administration of statin and the occurrence of ICH (p = 0.230) or sICH (p = 0.949). There was a trend toward better neurological function with higher statin dose. The use of statin in the early stage of ischemic stroke is safe and does not increase the risk of intracerebral hemorrhage after alteplase treatment, suggesting that a clinical trial of early statin treatment on a large scale following thrombolysis is needed for further evaluation.
