Risk Assessment

The American College of Cardiology/American Heart Association (ACC/AHA) Guidelines on Perioperative Cardiovascular Evaluation for Noncardiac Surgery provide an evidence-based approach to perioperative evaluation.18,19 According to these guidelines, the preferred approach to the diagnostic evaluation of the patient at risk of a cardiac event in association with a noncardiac procedure depends on the interactions of three factors: (1) patient-specific factors, (2) procedure-specific factors, and (3) exercise (functional) capacity of the patient. This approach is applicable to the perioperative evaluation of the patient with HTN requiring dental intervention.
