Myocardial injury after noncardiac surgery – an update

Purpose of review After successfully reducing mortality in the operating room, the time has come for anesthesiologists to conquer postoperative complications. This review aims to raise awareness about myocardial injury after noncardiac surgery (MINS), its definition, diagnosis, clinical importance, and treatment. Recent findings MINS, defined as an elevated postoperative troponin judged to be due to myocardial ischemia (with or without ischemic features), occurs in up to one in five patients having noncardiac surgery and is responsible for 16% of all postoperative deaths within 30 days of surgery. New evidence on risk factors, etiology, potential prevention strategies, treatment options, and the economic impact of MINS highlights the actionability of perioperative clinicians in caring for adult patients who are considered to be at risk of cardiovascular complications. Summary Millions of patients safely going through surgery suffer MINS and die shortly after the procedure every year. Without a structured approach to predicting, preventing, diagnosing, and treating MINS, we lose the opportunity to provide our patients with the best chance of deriving benefit from noncardiac surgery. The perioperative community needs to come together, appreciate the clinical relevance of MINS, and step up with high-quality research in the future.
