Cerebral infarction is considered a major disease, which has a high incidence, disability and mortality rate. A portion of the patients may have certain sequelae after actively pursuing treatment. If the patient has sequelae, it will usually affect the quality of life of the patient, and he/she will need to undergo rehabilitation or require care for the rest of his/her life. A portion of patients may be clinically cured after active and correct treatment. Even after cure, long-term oral medication is needed for secondary prevention to prevent reinfarction. Treatment mainly includes long-term oral aspirin to fight platelet aggregation, oral statins such as simvastatin, atorvastatin or resuvastatin to regulate lipids and stabilize plaque. At the same time, we should actively control the cause of the patient’s disease, the main causes of cerebral infarction include diabetes mellitus, hyperlipidemia and hypertension. Patients with hypertension usually take long-term oral blood pressure-lowering drugs, including levamlodipine, amlodipine benzenesulfonate, valsartan or irbesartan. Patients with diabetes mellitus are usually treated with long-term hypoglycemic therapy, preferring metformin orally, with the addition of glycopyrrolate or repaglinide if necessary, or subcutaneous insulin in severe cases.
