急性脑血管病发病与死亡的年节律等变化分析

本文对５年间２７４７例住院病人中的１９４１例脑血管病患者进行了统计。发现缺血性脑血管病全年发病机会大致相等，仅在某些月份有小的波动，但Ｐ＜０．０５；出血性脑血管病则男性３～５月份、９～１０月份、１２月份为发病高峰（Ｐ＜０．０５），而２、７月份最少；女性５、１２月份发病较多（Ｐ＜０．０５），１、７、１０月份最少。死亡人数在５月份最多（Ｐ＜０．１）；在一日２４小时中，死亡最容易发生的时间为下午５～６时及夜间１１时～２时；入院１２小时内、尤其８小时内死亡最多；另一死亡高峰时间为入院后１～４天时（Ｐ≤０．０５）。

AN ANALYSIS OF YEAR-RHYTHM IN THE ONSET AND THE DEATH OF ACTUAL CEREBROVASCULAR DISEASE

In this paper a statistical investigation was made in 1941 patients with cere-brovascular disease of 2747 in-patients during a 5 year period. The results showed that onsetprobability of ischemic cerebrovascular disease in one year was roughly same and appeared asamller fluctuation(but P>0. 05) in some months,however,the onset of hemorrhagic cere-brovascular disease presented the peaks for males from March to May or from September toOctober or in December(P<0.05),the periods of the less onset were in February or July,butfor females the peaks were in May or December(P<0.05),and the periods of the less onsetwere in Janury,July or October. Most of the patients died in May(P<0.1).In a day the timeof the easiest death was from 5 PM to 6 PM or from 11 PM to 2 AM. In these patients thepeak of death occurred in 12 h, especially in 8 h after their hospitalization,another peak ofdeath was from 1 d to 8 d after hospitalization(P≤0. 05)。
