EACTS Expert Consensus Statement on Perioperative Myocardial Infarction After Cardiac Surgery

Defining perioperative myocardial infarction (PMI) after cardiac surgery presents challenges. A multidisciplinary group evaluated the evidence on mechanisms, diagnosis, and prognosis of PMI. The review found that postoperative troponin thresholds associated with increased mortality risk are markedly higher than those found in current PM definitions. Large increases in other biomarkers are also prognostically relevant, even if supporting evidence of ischemia is lacking. A new algorithm for PMI detection was proposed, and researchers recommended that PMI should be included in the primary composite outcome of trials of coronary interventions.
