Cerebral infarction is the main fatal disease in China at present, mainly referring to patients in the acute stage, and it is related to the patient’s age, the severity of the disease and the site of infarction. Acute cerebral infarction is generally not life-threatening if the condition is stable after treatment. In mild cases of cerebral infarction, there are only symptoms such as distorted mouth and tongue, hemiplegia and unfavorable speech, which generally do not directly affect life expectancy, but if there are sequelae, the quality of life will be lower than before, and as long as the preventive treatment is adhered to without recurrence, there is no risk of life. Severe cerebral infarction, those with impaired consciousness, or those whose infarct site is related to the center of life activities, may be life-threatening. In addition, cerebral infarction itself does not necessarily lead to the patient’s death directly; complications after cerebral infarction, such as lung infection, gastrointestinal bleeding, etc., may lead to the patient’s life threatening, especially in patients who are bedridden for a long time, lung infection, bedsores and other diseases are the main factors leading to death, so comprehensive treatment and care for patients with severe cerebral infarction is very important and is the key to reducing death. Therefore, cerebral infarction is not a terminal disease, and the vast majority of mildly ill patients and most severely ill patients are able to stabilize their disease with effective treatment and adhere to prevention, and will live for a long time without affecting their life expectancy.
