Myocardial revascularization, either percutaneous or surgical, is the cornerstone of chronic and acute ischemic coronary artery disease therapy. Periprocedural myocardial injury and infarction are possible complications of these procedures. Several pathogenetic mechanisms have been proposed in the setting of percutaneous (distal embolism, vasospasm, obstruction of a minor vessel) or surgical revascularization (prolonged ischemic time, early graft failure, arrhythmia or severe hypotension during the procedure). High-sensitivity cardiac troponins have emerged as the recommended biomarkers due to their important prognostic implications. However, data regarding diagnostic criteria, management and prognostic implications of these complications are lacking. The present review aims to provide an overview regarding the possible diagnostic criteria, management and prognostic role of periprocedural myocardial injury and infarction.
