Discusses the challenges and importance of accurately diagnosing perioperative myocardial infarction and injury after cardiac surgery using high-sensitivity troponin.
Perioperative myocardial infarction is an important complication after cardiac surgery that leads to excess perioperative mortality. Perioperative myocardial infarction may be caused by inadequately treated preoperative ischemia, insufficient interoperative myocardial protection, or untoward surgical events (e.g., incomplete revascularization, graft failure, or embolization). Accurate early diagnosis of perioperative myocardial infarction may allow intervention in a timely manner to mitigate infarct size. In addition, valid criteria for perioperative myocardial infarction are needed so that clinical trials aimed at improving cardiac surgical outcomes can be designed and interpreted. Distinct from perioperative myocardial infarction, “significant” perioperative myocardial injury is a more nebulous term used . . .
