Cerebral infarction is a chronic disease, which is a common and frequent disease in neurology, mostly occurring in middle-aged and elderly people, and is an acute ischemic cerebrovascular disease. The main causes include diabetes mellitus, hypertension, hyperlipidemia and hyperhomocysteinemia, etc. The disease has a high disability and mortality rate, which seriously affects the quality of life of patients. After aggressive and correct treatment, some patients may still have some sequelae, including limb motor function and sensory impairment. Some patients may also develop swallowing dysfunction, including difficulty swallowing and choking on water, and individual patients may also develop impaired consciousness. Patients with cerebral infarction can generally be clinically cured after active and correct treatment if the infarction is mild. Even after the clinical cure of cerebral infarction, long-term secondary prevention treatment should be given, and the main drugs include aspirin, clopidogrel for antiplatelet aggregation, and statins such as simvastatin, resulvastatin and atorvastatin for lipid regulation and plaque stabilization.
