Coronary artery disease is a prevalent and growing problem in the United States leading to significant morbidity and mortality including myocardial ischemia and infarction. Diagnosis and treatment of myocardial ischemia under general anesthesia can present unique challenges for the anesthesiologist including interpretation of diagnostic monitoring data and options for therapeutic interventions. There are many complex factors that determine myocardial oxygen supply and demand; when these become imbalanced, myocardial ischemia occurs that can progress to infarction. Maintaining a high-degree of suspicion for myocardial events in the perioperative period is paramount to good patient outcomes. In fact, perioperative myocardial injury within 30 days of surgery, if considered as a disease entity, would be the third leading cause of death in the United States. This chapters reviews the diagnosis and treatment of such events.
