Patients with cerebral infarction should pay attention to the following aspects when extracting teeth: 1, antiplatelet or anticoagulant drugs should be discontinued 1 week before tooth extraction because antiplatelet drugs such as aspirin, hydroclopidogrel and anticoagulant drugs such as warfarin will lead to prolongation of coagulation time, and if they are not discontinued, they will easily lead to more than just bleeding during tooth extraction, which will bring about difficulties in the operation.2, for patients with cardioembolic strokes, the extraction of teeth can induce arrhythmias due to pain For patients with cardiogenic stroke, pain after tooth extraction can induce arrhythmia such as atrial fibrillation, thus increasing the risk of recurrence of cerebral infarction. For elderly patients with cerebral infarction, it is better to do electrocardiogram before tooth extraction to rule out cardiac disease.3. After the patient’s bleeding stops 1-2 days after tooth extraction, the treatment of antiplatelet agents and anticoagulants should be restarted to prevent recurrence of cerebral infarction.
