Coronary heart patients need to pay attention to the following aspects of tooth extraction: 1, pay attention to their blood pressure. If the blood pressure is too high during tooth extraction, it is easy to cause more than bleeding after tooth extraction, and it is easy to induce more serious heart disease situation.2, need to pay attention to their electrocardiogram changes, if the electrocardiogram in the past three months there are abnormalities or more obvious angina pectoris, it is recommended that the patient should not carry out the tooth extraction for the time being.3, if the patient is congenital, at this time, but also to consider whether there is the occurrence of cardiac insufficiency or heart failure, this time are contraindications to the extraction of teeth. If the patient has coronary artery disease, some patients after stenting are taking aspirin or even clopidogrel and other “double antibiotic” drugs, which may need to be stopped before extraction, and stopping the drugs may increase the risk of coronary artery disease, so the timing of extraction and the type of drugs to be stopped before the operation, and the number of days need to be communicated with the operator. Communication. Patients are advised to wait until their condition has stabilized, and most try to avoid extractions and can take other conservative treatment options. Coronary artery disease is suffered for many years, and in general the symptoms are mild and there is no angina pectoris in the last few years, the tooth extraction can be carried out under the exercise of cardiac monitor.
