Abstract
Background: The populations presenting for coronary artery bypass grafting surgeries (CABG) has been increasing in age, comorbidities and complexity of coronary diseases in current history. For cases to receive reliable data as well as to assess the accomplishments of the surgeons and the insti-tution, risks predictions has become more crucial. Aim of Study: To assess whether elevated preoperative cardiac troponin level impacts the outcomes after coronary artery bypass graft (CABG) or not. Patients and Methods: This prospective study included 40 patients separated into two groupings depending on the preoperative cTnI which was measured 24 hours before the operation: Group I: 20 patients will undergo CABG with Troponin I <0.04ng/ml. Group II: 20 patients will undergo CABG with Troponin I >!0.04ng/ml. Results: There was no significant difference among both groups as per the in-hospital mortality. Patients with elevated preoperative cTnI had longer ICU and hospital stay and prolonged ventilation time. Conclusion: Elevated preoperative troponin in patients presenting with acute coronary syndrome is not an independent factor that predicts the postoperative mortality. However, elevated cTnI is associated with more postoperative compli-cations. Delaying CABG till normalization of cTnI levels seems to be better to avoid postoperative complications.
