Association Between Continuously Recorded ST Changes and Perioperative Myocardial Injury: An Explorative Prospective Cohort Study.

Absolute ST-segment deviation >1 mm from individualized lead baseline was also associated with perioperative myocardial injury (RR, 2.03; 95% CI, 1.01-4.06; P = .046).

When ST-depression was added to the baseline model, including age and the American Society of Anesthesiologists (American Society of Anesthesiologists) physical status classification system, overall net risk classification improved (NRI, 0.50; 95% CI, 0.16-0.86).
