Patients with cerebral infarction have no sequelae, probably because the blockage is relatively small or because the patient’s cerebral blood flow is well restored due to timely treatment, so the patient’s neurological deficit symptoms are completely restored. However, in this case the patient should also actively look for the cause and then intervene to prevent the patient from having another cerebral infarction. If the patient has atrial fibrillation or heart valve disease, the patient should be given oral warfarin or rivaroxaban anticoagulation therapy to prevent cardiogenic emboli from dislodging and forming cerebral embolism problems. If the patient is caused by cerebral arteriosclerosis, cerebral vascular stenosis and other reasons, the patient should take oral aspirin or clopidogrel hydrogen sulfate anti-platelet aggregation, which can effectively prevent the formation of thrombus in the patient. At the same time, patients should strictly control blood pressure, blood lipids, blood sugar, blood homocysteine and other risk factors, and have a low salt and low fat diet, quit smoking and limit alcohol in their lifestyle.
