Perioperative cardiac risk assessment and management.

Perioperative cardiac morbidity is the leading cause of death following the administration of general anesthesia. With the aging of the population, the number of patients at significant cardiac risk for noncardiac surgical procedures is expected approximately to double over the next 30 years. Assessing cardiac risk will assume increasing importance in surgical decisions. Historical predictors, diagnostic testing predictors, and recent data concerning preoperative cardiac physiology assessment and optimization are discussed.
