title: [Trend analyses in the incidence of acute intracerebral hemorrhage events and acute cerebral infarction events in urban areas in Beijing].
abstract: OBJECTIVE
  To study the trends of incidence on acute intracerebral hemorrhage events and acute cerebral infarction events in the population aged 25 - 74 in urban areas of Beijing from 1984 to 1999.
  
  
  METHODS
  In monitoring the trends and determinants in the cardiovascular disease (MONICA) project and subsequent study, acute intracerebral hemorrhage events and acute cerebral infarction events were registered in a standardized way in men and women aged 25 to 74 years from 1984 - 1999.
  
  
  RESULTS
  Both intracerebral hemorrhage attack rates decreased but cerebral infarction attack rates increased significantly; The proportion of intracerebral hemorrhage events in stroke events decreased from 42.0% to 16.0% while the proportion of cerebral infarction events in stroke events increased from 55.8% to 81.6%, the changes in incidences of acute intracerebral hemorrhage events and acute cerebral infarction events in various age groups were different.
  
  
  CONCLUSIONS
  Cerebral infarction was the most important risk causing stroke, so prevention of cerebral infarction should be strengthened in the area.
