Abstract: ObjectiveTo analyze cerebral hemorrhagic infarction (HI) and relative factors with the database of Standard Stroke Registry (SSR).Methods1 487 consecutive patients with acute ischemic stroke admitted within 3 days after onset were analyzed with SSR.ResultsHI was observed in 11% of patients, of whom 51% were diagnosed as having cardiogenic embolism. In patients with supratentorial infarction of cardiac origin, 28% had HI (mild 67%, moderate 23, hematoma 10%). On multiple logistic regression analysis, independent factors related with HI were found to be age, prosthetic cardiac valve and NIHSS scores at admission. Patients with more severe HI were associated with a poorer outcome at discharge. Clinical outcome tended to be better in patients receiving thrombolytic agents than in those without receiving agents, while the incidence of HI was slightly more frequent in the former.Conclusion It is confirmed that the SSR database is useful for understanding and analyzing the status of stroke diagnosis and management throughout the nation, and revisions are needed in some formats.
