Safety of dental treatment in patients with previously diagnosed acute myocardial infarction or unstable angina pectoris.
OBJECTIVE
The purpose of this study was to assess the safety of invasive dental treatments, such as tooth extraction and pulpectomy under local anesthesia, in patients with unstable angina pectoris and within 6 months after onset in patients who had experienced acute myocardial infarction.


METHODS
Cardiovascular complications during and after dental treatment and preoperative risk factors were explored in 63 patients who had experienced unstable angina pectoris or acute myocardial infarction.


RESULTS
A total of 79 dental treatments were performed with no intraoperative complications. Chest pain occurred in 8 patients within 1 week after dental treatment. Risk factors for postoperative complications were identified as a history of chest pain within 2 weeks before the dental treatment and failure to clear the Master Test Single stress test.


CONCLUSIONS
Many patients who had experienced unstable angina pectoris or acute myocardial infarction tolerated dental treatment when appropriate stress control measures were used. However, approximately 10% of the patients experienced postoperative problems. Acceptability of dental treatment should be determined on the basis of the comprehensive assessment of each patient.
