If the symptoms of cerebral infarction are mild and well controlled, life expectancy is usually not affected. If the infarction develops over a large area and has serious sequelae, the survival time is usually related to the severity of the infarction, the location of the infarction, and whether the treatment is timely. If the patient is in good health and the infarction is not large, as long as the treatment is standardized in time and the risk factors are well controlled, the life expectancy will not be affected. If the area of cerebral infarction is relatively large, especially in key areas, such as brainstem infarction, it may affect the respiratory and circulatory system, leading to serious complications, then it may jeopardize the patient’s life at any time. At the same time, if the cerebral infarction is not treated in time, it may also lead to the aggravation of the disease and the expansion of the infarction, thus endangering the life. Patients with stroke with cerebral infarction should go to the hospital in time, early detection and early treatment, to avoid delaying the condition and endangering the patient’s life.
