Background:­ This study aims to evaluate the potential ofischemia-modified albumin (IMA) to predict the myocardialinfarction in on pump coronary artery bypass grafting(ONCABG) patients.Methods: Fifty elective isolated ONCABG patients (41 males,9 females; mean age 66 years; range 56 to 75 years) were includedin the study. Patients were divided into perioperative myocardialinfarction (PMI; n=8) and non-infarction (NPMI; n=42) groupsaccording to perioperative cardiac troponin I (cTnI) values andECG findings. Serum IMA levels were measured preoperatively,20 minutes after aortic cross clamping, 30 minutes, at 3, 6,12 and 24 hours after declamping.Results:­ Compared to the NPMI group, the declamping 30minutes, 3, 6 and 12 hours IMA levels were higher in the PMIgroup (p=0.002, p=0.048, p=0.023, p=0.007, respectively). Inboth NPMI and PMI groups, the 20 minutes after aortic crossclamping IMA levels were higher compared to the preoperativeIMA levels (p=0.0001, p=0.038, respectively).Conclusion:­ Our study results show that IMA may be anearly marker of myocardial infarction in the ONCABGpatients.
