The cure rate of cerebral infarction is about 40%, mainly seen in patients with small cerebral infarction, radiocoronal area, and lacunar cerebral infarction, with high disability and mortality rates, which seriously affect the quality of life of patients. Patients with acute cerebral infarction have a mortality rate of approximately 5%-15%, and those who survive have a disability rate of approximately 50%. Patients with cerebral infarction should be given the right treatment early. If the patient is cured, long-term secondary prevention should be given to prevent the occurrence of reinfarction, mainly by applying aspirin against platelet aggregation. Meanwhile, statins are applied to regulate lipids and stabilize plaques. The main risk factors causing cerebral infarction include hyperlipidemia, hypertension and hyperglycemia, and hyperhomocysteinemia. If the patient has the above risk factors and is older than 50 years old, aspirin should be routinely given to anti-platelet aggregation and, at the same time, to control the risk factors. To make the patient’s blood pressure stable, long-acting agents, mainly amlodipine levulinate and amlodipine benzoate, are usually applied. For patients with diabetes mellitus, blood glucose should be actively controlled to keep it around 6 mmol/L. Metformin should be mainly applied, and subcutaneous insulin injection therapy can be given if necessary.
