AbstractPerioperative myocardial infarction represents the most common cardiovascular complication following non-cardiac surgery, but frequently presents without the usual clinical signs and symptoms consistent with acute coronary syndrome. Given the silent nature of this event, a clinician's reliance on risk stratification tools and cardiac specific biomarkers to assist in the identification of at-risk individuals is heightened in the perioperative setting. Although cardiac troponin elevations following non-cardiac surgery have been consistently linked to increased mortality, uncertainty remains over how to clinically intervene to prevent harm. This decision is further complicated by the increasing sensitivity of the newest generation of cardiac biomarker immunoassays. In this narrative review, the growing body of evidence surrounding cardiac troponin elevations in the perioperative setting, how the evidence has been integrated into recent clinical practice guidelines, and its implications for the detection of perioperative myocardial infarction are discussed.
