Trend analyses in the incidence of acute intracerebral hemorrhage events and acute cerebral infarction events in urban areas in Beijing / 中华流行病学杂志

ABSTRACT

<p><b>OBJECTIVE</b>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.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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.</p><p><b>CONCLUSION</b>Cerebral infarction was the most important risk causing stroke, so prevention of cerebral infarction should be strengthened in the area.</p>
