People who have had a cerebral infarction should try not to drink alcohol. Drinking alcohol can damage the intima of blood vessels, which can cause tangible components of blood to accumulate in the walls of blood vessels, leading to narrowing of the lumen and easily causing insufficient blood supply to the brain, which can cause cerebral infarction in severe cases. Alcohol consumption is an independent risk factor for cerebral infarction, and other risk factors include hyperlipidemia, hyperglycemia, hypertension, hyperhomocysteinemia, as well as age, gender, seasonality and smoking and weight. For patients with cerebral infarction, smoking and alcohol should be stopped and secondary prevention treatment should be given, which mainly includes long-term application of aspirin for antiplatelet aggregation and oral statins for lipid regulation and plaque stabilization, commonly used drugs include simvastatin, atorvastatin, and rasulvastatin. Other risk factors, such as hyperglycemia, hypertension and hyperhomocysteinemia, should be controlled accordingly; if patients are obese, they should exercise and control their body weight appropriately.
