Myocardial injury in non-cardiac surgery: complexities and challenges.

The term MINS (myocardial injury after non-cardiac surgery) was coined to broadly describe perioperative troponin elevation that is deemed to be due to a cardiac cause. However, this term is commonly used in literature to represent cases that do not fulfil the criteria for the diagnosis of myocardial infarction. Asymptomatic troponin elevation that does not fulfil the criteria for acute coronary syndrome in the perioperative setting has been shown to be associated with increased mortality. The discovery of MINS presents new opportunities to improve outcomes for surgical patients. Unfortunately, awareness of MINS among practitioners remains low and implementation of perioperative troponin monitoring is poor. Given its significance, the detection, management and prevention of MINS should not be overlooked. Copyright: © Singapore Medical Association.
