Patients with cerebral thrombosis can take fish oil, but this does not bring obvious benefit to the patient, so patients with cerebral thrombosis can not give up the regular drug treatment, and rely on fish oil for treatment. After cerebral thrombosis, the problem is secondary prevention, which is divided into two aspects, one is non-pharmacological treatment, and the other is pharmacological treatment. 1, non-pharmacological treatment includes low-salt, low-fat diet, diabetic diet when blood glucose is high, eating more fresh vegetables, diligent exercise, regular rest and relaxation, and maintaining emotional stability. 2, pharmacological treatment includes antithrombotic, lipid-lowering, blood pressure-lowering, sugar-lowering, anticoagulant treatment is needed for patients with atrial fibrillation, and antitussive therapy is needed for patients with atrial fibrillation. Patients with atrial fibrillation need anticoagulant therapy; antithrombotic drugs are usually aspirin or clopidogrel; lipid-lowering drugs are Rosuvastatin or atorvastatin; antihypertensive drugs are usually amlodipine, temsirolimus, valsartan and other long-acting antihypertensive drugs; and antihyperglycemic drugs such as glimepiride, metformin, or insulin can be used to control blood glucose.3. In addition, lipids need to be detected 1-2 times a year, and blood glucose needs to be detected frequently. Tests.
