222 Prognostic value of high-sensitivity cardiac troponin I early after coronary artery bypass graft surgery

Abstract Aims The diagnosis of periprocedural myocardial infarction (PMI) after coronary artery bypass graft (CABG) is based on biochemical markers along with clinical and/or instrumental findings. However, there not a clear cut-off value high-sensitivity cardiac troponin (hs-cTn) to identify PMI. We hypothesized that isolated hs-cTn concentrations in the first 24 h following CABG could predict adverse events (in-hospital death and PMI) left ventricular ejection fraction (LVEF) decrease. Methods results retrospectively enrolled all consecutive adult patients undergoing at our Institution over 1 year. Hs-cTnI (Access assay, Beckman-Coulter) were serially measured post-operative period correlated outcomes. 300 enrolled; 71.3% them underwent alone, mainly on-pump (96.7%), 33.7% setting an acute syndrome. Most showed hs-cTnI values superior limit required by latest guidelines for Five (1.7%) died, 8% developed PMI, 10.6% LVEF decrease ≥10%. did correlate or PMI whereas they ≥ 10% (P-value < 0.05 any time interval).
