As patients with cerebral infarction are often accompanied by hypertension, lipid metabolism disorders, etc., attention should be paid to a reasonable dietary structure in the diet, while choosing the appropriate drug therapy and relapse prevention according to different etiologies, specifically including: Diet: the diet of patients with cerebral infarction should pay attention to reducing salt intake, reducing alcohol intake, reasonable diet, to consume low-fat, rich in high-quality protein, carbohydrates, vitamins, trace elements of food as the principle. Patients with cerebral infarction should pay attention to nutritional diversity, and the diet should include cereals, fresh vegetables, fruits, meat, poultry, eggs, fish, beans and soy products, milk, etc. If the patient is bedridden and has weak digestive function after cerebral infarction, the food should be made into soft food, which is easy to digest. Anti-thrombotic: The most important drugs for cerebral infarction are anti-platelet aggregation drugs, mainly including aspirin, clopidogrel, cilostazol, etc. These drugs stop the local thrombus from progressing and expanding by inhibiting platelet aggregation and release. For cerebral infarction caused by consideration of atrial fibrillation, anticoagulant drugs are often applied to prevent re-embolism, and the commonly used oral anticoagulant drug is warfarin, which needs to be monitored to control the international normalized ratio (INR) at 2.0~3.0. There are also some new oral anticoagulant drugs such as dabigatran, which do not need to monitor INR. Lipid-lowering: statin use is also very important for non-cardiogenic atherosclerotic cerebral infarction. Commonly used are atorvastatin and rasulvastatin. Those with hypertension should control their blood pressure and take oral antihypertensive drugs. Antiplatelet agents, statins, and antihypertensive drugs are the three cornerstones of cerebral infarction treatment. Control of risk factors: As patients with cerebral infarction are often accompanied by diabetes, they should apply corresponding hypoglycemic drugs under the guidance of doctors, and if combined with homocysteinemia, choose the combination of folic acid, vitamin B6, and vitamin B12. In addition, some traditional Chinese medicines, such as circulation improvement and neurotropic drugs, can also play an auxiliary therapeutic role. In conclusion, patients with cerebral infarction should develop individualized health education programs for different risk factors, establish a reasonable lifestyle, such as quitting smoking, reducing alcohol intake, eating reasonably, exercising appropriately, and regular medical checkups and adherence to medication for high-risk patients.
