The life expectancy of patients with cerebral infarction and heart attack is related to the area of infarction, the part of infarction and whether it is treated in time, and there is no absolute life expectancy. 1. The area of infarction: if the area of infarction is small, it will not affect the life expectancy, such as lacunar cerebral infarction and light myocardial infarction. If the infarction area is large, it may affect the blood supply of cardiovascular and cerebrovascular vessels and affect the life expectancy of patients, such as acute sudden death. 2. Related to the part of infarction: such as lacunar cerebral infarction, focal myocardial infarction, more than will not cause serious consequences, and some patients even have no obvious symptoms. If the infarction occurs in important parts, such as brainstem infarction, the general condition is more dangerous and the death rate is higher. 3. Whether timely treatment: acute cerebral infarction, heart attack acute stage, if timely and effective treatment, after active treatment, usually in accordance with the doctor’s orders for long-term medication, generally can be long-term survival. If there is no timely treatment, there is a possibility of sudden death, in addition to the stabilization of the condition, not on time to take medication, will also affect the life expectancy, may cause acute relapse of cardiovascular and cerebrovascular diseases, sudden death. There are many factors affecting the life expectancy of patients with cerebral infarction and cardiac infarction, and they should actively seek medical attention and standardized treatment under the guidance of doctors to strive for a good prognosis.
