Abstract
There is only a few evidence for stroke management has been reported from Japan. It is necessary to make a data bank of acute stroke patients as infrastructure to make evidence for standardization of stroke management. We made Japan standard stroke registry study (JSSRS) supported by ministry of health and welfare from 1999 to 2002. We completed computerized registry system and accumulated about 8, 000 acute stroke cases from 45 stroke center hospitals. This system is also functioning as a stroke database for each hospital. From the analysis of the distribution of stroke subtype, the incidence of atherothrombotic infarction and cardiogenic embolism was similar to lacunar infarction as shown in Figure 1. Furthermore, the 38% of ischemic stroke patients admitted within 3 hours. Thrombolytic therapy was performed in 15% of the patients who admitted within 3 hours and their initial severity were NIHSS 6-29. The outcome of the patients treated with thrombolytic therapy was significantly better than those without it. These data indicate that the stroke data bank should be useful tool to make verification of the guideline and planning a clinical trial for EBM in near future.
