Long-term outcomes of time-dependent phenotypes of perioperative myocardial injury^☆.

ABSTRACT:

Background

Perioperative myocardial injury (PMI) is associated with increased short-term major adverse cardio- and cerebrovascular events (MACCE) and mortality. We evaluated how different phenotypes of PMI based on timing of injury impact long-term MACCE and mortality among patients undergoing major noncardiac surgery (NCS).

Methods

A prospective, observational study was carried out in 1290 patients aged ≥50 yr undergoing major noncardiac surgery. High-sensitivity cardiac troponin T (hs-cTnT) was measured before surgery and up to 3 days after surgery. Patients were classified into four groups: (1) no hs-cTnT elevation, (2) isolated preoperative hs-cTnT increases, (3) normal preoperative hs-cTnT with perioperative elevation, and (4) increased preoperative hs-cTnT with periope
