Stroke, also called cerebrovascular disease, is always the third most common cause of death in the recent year in Taiwan. Giving thrombolytic therapy within three hours of the first sign of stroke is efficient to help stroke patient limit stroke damage and disability. Therefore, the studies for the correlation of the arrival time and acute stroke and the correlation of the arrival way and acute stroke are important for thrombolytic therapy. In this thesis, we use the data from the stroke registry provided by the HsinChu General Hospital from 2006 to 2008. The relationship between NIHSS score and arrival ways, and the relationship between arrival time and arrival ways are investigated. In addition, we also explore the relationship between risk factors, Barthel index etc and the arrival time.
