The mortality rate in the acute phase of cerebral infarction is about 5%-15%, and the disability rate in surviving patients is about 50%. There are many causes of death due to cerebral infarction, including severe cerebral edema and increased intracranial pressure, which are common complications of acute severe cerebral infarction and are among the leading causes of death. In addition, patients with cerebral infarction can have dysphagia, causing aspiration, aspiration pneumonia, and complications of fever and infection. In the acute phase of cerebral infarction patients can develop stress ulcers, which manifest as bleeding, erosion and acute ulcers of the gastric and duodenal mucosa. In addition, water and electrolyte disorders can occur in patients with cerebral infarction, which can cause acute myocardial ischemia, myocardial infarction, cardiac arrhythmia and heart failure, which is one of the main causes of death in acute cerebrovascular disease.
