Elevation of aspartate aminotransferase predicts mortality after coronary artery bypass grafting

Cardiac troponins are the recommended biomarkers for diagnosing myocardial infarction (MI). Since troponins have become widely available, the roles of other less specific biomarkers have been seldom studied. Aspartate aminotransferase (AST) not only correlates with MI, but also with liver injury due to ischaemia or congestion. We assessed whether post-operative AST levels were associated with adverse outcomes after contemporary coronary artery bypass grafting (CABG).
