利用圆形分布法分析脑血管病发病时间

ANALYSIS OF TIME OF STROKE ONSET

调查了1989年9月1日至1990年2月28日在泰安市四家医院住院的197例脑血管病病人。其中脑梗塞(脑血栓形成和脑栓塞)113例,脑出血84例。用圆形分布法分析脑梗塞与脑出血的发病时间,脑梗塞发病的平均时间为9:06Am,以4:00Am～10:00Am发病人数最多(占56％)。脑出血发病的平均时间为3:45pm,以2:00pm—8:00pm发病人数最多(占15％)。脑梗塞与脑出血的发病平均时间有高度显著性差别(P<0.01).

We investigated 197 patients with stroke Sep. 1, 1989to Feb. 28, 1990. Of them. 113 suffered from ischemic stroke and 84 from intraparenchymal hemorrhage. We analysed the onset time of ischemic stroke and intraparenchymal hemorrhage by circular distribution method. The average time of ischemic stroke onset is 9:06Am, most ischemic strokes occurred from 4: 00Am to 10: 00Am. the incidence of ischemic stroke onset declined during the other time. The average time of intraparemchymal hemorrhage is 3: 45pm. time central onset tendency is from 2:00pm to 8:00pm. The overage time of ischemic stroke and intraparenchymal hemorrhage onset have significant differences (P<0. 01).
