The present study is to be conducted based on the AIS patient data collected from CNSR I, II, and III. The primary objectives are: * To investigate the temporal changes in the proportion of intravenous recombinant plasminogen activator (IV rtPA) treatment from 2007 to 2017 among Intravenous Thrombolytics (IVT) eligible patients (patient groups B and B') and overall AIS patients (patient group A) in China; * To investigate the temporal changes in IV rtPA treatment time intervals from 2007 to 2017 among IV rtPA treated patients (patient groups C and C') in China. The secondary objectives are: \- To describe the demographic and clinical characteristics of the IV rtPA treated patients (patient groups C and C'), IVT eligible patients (patient groups B and B') and the overall AIS patients (patient group A) from 2007 to 2017 from the CNSR I to III.
