  • This scientific statement offers a clinical perspective of myocardial injury after non-cardiac surgery (MINS), which discusses the definition, epidemiology, pathophysiology, prognosis, and management of MINS, and future directions for research.
  • MINS is an important clinical diagnosis defined by an elevation of cardiac troponin after non-cardiac surgery, with or without ischemic symptoms or electrocardiographic abnormalities, after the exclusion of alternate non-ischemic causes of troponin elevation.
  • MINS was first described in 2014 and is a relatively new clinical diagnosis. There are still clinically relevant questions regarding MINS pathophysiology, pre-operative risk stratification, and post-operative management. Efforts to improve recognition and understanding of MINS help improve post-operative outcomes after non-cardiac surgery.
