Patients with a second recurrence of cerebral infarction may be in a more serious condition, or the treatment may not be as effective as the first attack, which was treated well, but the patients do not necessarily die, and their prognosis depends mainly on the vessels involved in the lesion, the site of infarction, the size of the infarct foci, the type of infarction, and whether there are comorbidities related to it. In patients with cerebral infarction, the mortality rate in the acute phase is about 5%-15%, and the disability rate in surviving patients is about 50%. There are many factors affecting the prognosis of cerebral infarction, the most important being the severity of the neurological deficit, other factors including the age of the patient and the cause of the stroke. In patients with cerebral infarction, secondary prevention therapy should be given during the recovery period to actively address all stroke risk factors that can be intervened, and the use of anti-platelet aggregation drugs can reduce the risk of stroke recurrence.
