Myocardial injury after non-cardiac surgery (MINS) is a common and serious complication that significantly affects perioperative survival. Despite rare intraoperative anesthesia-related deaths, about 1% of non-cardiac surgery patients die within 30 days after surgery. With a large number of surgeries performed annually, postoperative death is the second leading cause of death in the United States. MINS is defined as an elevation in troponin concentrations within 30 days postoperatively. Preventive measures, systematic surveillance approaches, and treatment standards for MINS are still lacking, but there are modifiable factors that can be considered in clinical practice, such as hemodynamic control, adequate oxygen supply, metabolic homeostasis, perioperative medication use, and anesthesia choices.
Myocardial injury is a frequent complication of surgical patients after having non-cardiac surgery that is strongly associated with perioperative mortality. While intraoperative anesthesia-related deaths are exceedingly rare, about 1% of patients undergoing non-cardiac surgery die within the first 30 postoperative days. Given the number of surgeries performed annually, death following surgery is the second leading cause of death in the United States. Myocardial injury after non-cardiac surgery (MINS) is defined as an elevation in troponin concentrations within 30 days postoperatively. Although typically asymptomatic, patients with MINS suffer myocardial damage and have a 10% risk of death within 30 days after surgery and excess risks of mortality that persist during the first postoperative year. Many factors for the development of MINS are non-modifiable, such as preexistent coronary artery disease. Preventive measures, systematic approaches to surveillance and treatment standards are still lacking, however many factors are modifiable and should be considered in clinical practice: the importance of hemodynamic control, adequate oxygen supply, metabolic homeostasis, the use of perioperative medications such as statins, anti-thrombotic agents, beta-blockers, or anti-inflammatory agents, as well as some evidence regarding the choice of sedative and analgesic for anesthesia are discussed. Also, as age and complexity
