If a patient develops a cerebral infarction at the age of 45, the exact length of time he or she can live is affected by a variety of factors and cannot be generalized. Under normal circumstances, if the infarction is mild, the infarct is small and does not involve important areas such as the brainstem or basal ganglia, the patient’s life expectancy is generally not affected if the condition does not worsen further after treatment. If the infarct site is located in the brainstem and other important parts or the infarct area is large, the prognosis is worse and may lead to functional impairment, and in severe cases, coma and respiratory distress may occur, and then death may occur at any time. And those with severe cerebral infarction leading to long-term bed rest often end up with life-threatening complications such as aspiration pneumonia and pressure sore infection. Therefore, patients with cerebral infarction should actively improve their living habits, quit smoking and limit alcohol, control risk factors, rehabilitate and exercise, and take medication on time to prevent secondary recurrence of cerebral infarction.
