Cardiac Biomarker Levels Strongly Predict Outcome of Bypass Surgery

EurekAlert -- Levels of a biomarker used in the diagnosis of heart attacks are almost universally elevated in patients who have undergone coronary-artery bypass grafting (CABG) and, when markedly elevated, are powerfully prognostic, a team of researchers from the Massachusetts General Hospital (MGH) Heart Center has found. Their report implies that, while measurement of cardiac troponin T (cTnT) can help determine patient prognosis, current consensus recommendations regarding the use of cTNT to diagnosis post-CABG heart attack (myocardial infarction) probably should be reconsidered. The paper appears in the September 8 issue of Circulation and has been released online,
