Patients with cerebral infarction do not need spring and fall injections, which do not play a preventive role for patients with cerebral infarction. Prevention of cerebral infarction requires long-term oral medication, mainly including long-term application of aspirin for antiplatelet aggregation, oral simvastatin, resulvastatin, and atorvastatin for lipid regulation and plaque stabilization. During the application of statin therapy, liver function should be checked regularly. If the patient has elevated transaminases that exceed three times the normal value, statin therapy should be discontinued. In patients with hypertension, blood pressure should be actively regulated so that the patient’s blood pressure is stable and should not be high or low. High and low blood pressure can damage the intima of blood vessels and can aggravate atherosclerosis, which can lead to an increased risk of cerebral infarction. Patients with hyperglycemia should also have their blood glucose regulated, and those with hyperhomocysteinemia should be treated with homocysteine lowering therapy.
