The risk of death one year after a stroke

Source: Studies and Results No. 939, October 2015 Author: Christine de Peretti In 2008 and 2009, nearly 200,000 people were hospitalised for stroke in France, including 125,500 adults under the general sickness insurance scheme. Of these, 29 % were between the ages of 18 and 64, half were between 65 and 84 years old and 21 % were at least 85 years old. 62 % of patients had brain infarction, 26 % had haemorrhagic stroke, and in 12 % of cases, the type of stroke was not specified. Stroke is a major cause of death and disability. The proportion of patients who died was 14.5 % at initial hospitalisation, 16 % in the month following stroke and 28 % in the year. The lethality of cerebral haemorrhage is significant, with a standardised mortality rate at one month almost five times higher than that of brain infarction, and almost three times as much at one year. For all types of stroke, chronic pathologies significantly increase mortality at one year, and their weight as an initial cause of death increases over time. Multivariate analysis shows better survival for patients who have received intensive care bed passage.来源：2015年10月第939号研究与成果报告 作者：克里斯汀·德·佩雷蒂（Christine de Peretti） 2008年至2009年间，法国共有近20万人因脑卒中住院治疗，其中纳入普通疾病保险计划的成年患者达125500例。在这些患者中，29%的年龄介于18至64岁之间，50%的年龄处于65至84岁区间，另有21%的患者年满85周岁。其中62%为脑梗死患者，26%为出血性脑卒中患者，剩余12%的病例未明确脑卒中分型。 脑卒中是引发死亡与残疾的主要病因。初次住院期间的患者病死率为14.5%，脑卒中后1个月内的病死率为16%，1年内的病死率达28%。 脑出血的致死性显著：其标准化1个月病死率几乎为脑梗死的5倍，1年病死率则接近脑梗死的3倍。 针对所有类型的脑卒中，慢性基础疾病会显著升高患者1年内的病死率，且这类疾病作为首要致死病因的占比随时间推移逐步上升。多变量分析结果显示，接受过重症监护病房收治的患者生存率更高。
