Fifty three percent of all deaths within 30 days of stroke were due to the direct neurological sequelae of the stroke.Patients with primary intracerebral or subarachnoid haemorrhages were significantly more likely to die in this way than those with cerebral infarction(relative risk 4-1l 95%confidence interval 3-4--4-9)and 56%of such deaths occurred within 72 hours of onset.In patients with cerebral infarction,51%of deaths were due to complications of immobility(for example,pneumonia,pulmonary embolism) and these were more likely to occur after the first week.These findings have implications for clinical practice and the planning of clinical trials. |
