Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The objective of the study is to find out the in-hospital clinical outcomes among Chinese Acute Ischaemic Stroke (AIS) patients, who were treated with intravenous (IV) Recombinant Tissue Plasminogen Activator (rt-PA) within 4.5 hours of symptom onset in different age groups (18 to 80 years and above 80 years).
