ASSOCIATION BETWEEN INTRAOPERATIVE HEART RATE AND POSTOPERATIVE MYOCARDIAL INJURY IN PATIENTS FOLLOWING NON-CARDIAC SURGERY

Approximately 10% patients who undergo non-cardiac surgery show biochemical evidence of myocardial injury, which is associated with cardiac complications and death.[1] The aetiology and mechanisms of perioperative myocardial injury are incompletely understood. Observational studies have described associations between perioperative tachycardia and postoperative cardiac complications. However, 'tachycardia' was often poorly defined and its association with myocardial injury has not been investigated.
