BackgroundPerioperative myocardial injury (PMI) remains a major cause of perioperative morbidity and mortality but clinical strategies to prevent PMI are still uncertain.Methods And ResultsWe comprehensively searched PubMed for major research articles concerning clinical strategies to prevent PMI. The key findings are as follows: (1) the American College of Cardiology/American Heart Association guideline update for perioperative cardiovascular evaluation for noncardiac surgery is very useful to stratify cardiac risk preoperatively; (2) cardiac troponin has emerged as a biomarker to diagnose postoperative PMI and to predict clinical outcomes; (3) coronary revascularization before noncardiac surgery probably would provide cardiac protection in select patients, especially in patients with high-risk coronary artery disease; (4) elective noncardiac surgery should be postponed in patients who received coronary stenting recently because of high incidence of serious cardiac complications (minimum 6-8 weeks for bare metal stents and 6-12 months for drug-eluting stents); and (5) beta-blockers and statins are very promising drugs and probably would prevent PMI in a select patient population, especially in patients with intermediate risk and stable coronary artery disease.ConclusionsFurther studies, especially randomized clinical trials and mechanistic investigation are needed to find the best and effective clinical strategies to prevent/reduce PMI.
