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.
