Low Superoxide Dismutase and Catalase Is Associated Malondialdehyde and Ischemia Modified Albumin in Patients With Non-St Elevated Myocardial Infarction (Nstemi)

Abstract

Non-ST elevated myocardial infarction (NSTEMI) diagnosis is difficult when the electrocardiography (ECG) normal and troponin parameters are slightly higher than the normal reference range. This study aimed to assess the IMA (ischemia modified albumin), MDA (malondialdehyde), SOD (superoxide dismutase), and catalase in patients with NSTEMI. The present study included 55 patients with NSTEMI and 55 healthy subjects prospectively. IMA, MDA, SOD, and catalase levels were measured from venous blood obtained from each patient within twelve hours after the onset of symptoms. Differences between the two groups were evaluated with Student's unpaired t-test for parameters with a normal distribution. IMA (3.14 ± 0.06 vs. 1.49 ± 0.03) and MDA (3.14 ± 0.06 vs. 1.49 ± 0.03) were higher, and SOD (1.10 ± 0.03 vs. 2.31 ± 0.02) and catalase (0.54 ± 0.02) vs. 0.22 ± 0.02) were lower in NSTEMI patients than control subjects. There was a significant correlation among IMA, MDA, SOD and catalase. Our data reveal that levels of MDA and IMA were increased, and SOD and catalase levels were decreased significantly in patients with NSTEMI. Blood concentrations of oxidant and antioxidant parameters could assess the oxidative state in patients with NSTEMI. © 2021, Yuzuncu Yil Universitesi Tip Fakultesi. All rights reserved.
