Values are given as percentage (number) of patients.
*
Current recommendations given by Auerbach and Goldman 1 with intermediate-risk patients having 1 major or 2 minor risk factors and high-risk patients having 3 or more major risk factors for perioperative ischemia.
†
Percentage (number) of patients administered preoperative B-blocker among patients who were not taking B-blocker as an outpatient.
‡
