脑卒中的季节性发病及预防

Seasonal Attack and Prevention of Brain Stroke

目的 探讨季节变化对脑卒中发病的影响。方法 对２ 年内收入院的６２５ 例脑卒中（ 脑出血１６７例与脑梗塞４５８ 例） 患者进行观察，并按季节分配成４ 部分，计算各自的构成比。结果 冬季脑出血的构成比明显高于夏季，而脑梗塞则以夏季为高（ Ｐ＜ ０ ．０５） 。结论 冬季以出血性脑卒中患者居多，夏季以缺血性脑卒中多见，做好季节性预防工作十分必要。

Objective To study the influence of seasonal variation on brain stroke. Methods 625 patients (167 patients with cerebral haemorrhage and 458 patients with cerebral infarction ) were investigated and divided into four parts according to season. The composition ratio of every part was calculated .Results The composition ratio of cerebral haemorrhage in winter was higher than in summer and cerebral infarction in summer was higher(P<0.05).Conclusion There are more patients with cerebral haemorrhage in winter and much more patients with cerebral infarcton in summer.It is necessary to do preventive work well seasonally.
