Comparison of Biochemical Parameters with Inhibition of Oxidative Stress in Myocardial Infarction Patients: In Vitro Study

Myocardial infarction (MI) is the main cause of illness, mortality, and stress worldwide. Oxidative stress is the major cause of myocardium tissue damage associated with cell necrosis.

The current study was designed to compare biochemical parameters with in vitro antioxidant activity in MI patients.

This observational cohort study was conducted on 53 MI patients, and the samples were collected on the basis of a nonrandom sampling technique from April 2022 to November 2022. Lipid profile (i.e., total cholesterol (TC), high-density lipoprotein (HDL), low-density lipoprotein (LDL), very-low-density lipoprotein (VLDL), and triglycerides (TG)) and cardiac profile (i.e., troponin T, troponin I, creatine kinase MB (CK-MB), and creatine phosphokinase (CPK)) were measured for the confirmation of variation in biochemical parameters. Afterward, the inhibition of oxidative stress was analyzed through the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay on the serum samples of the patients.

Of 53 MI patients, 33 and 20 cases were male and female, respectively. Moreover, the correlation of the DPPH assay with TC, troponin T, and troponin I was determined by Pearson correlation. The correlation coefficients range from -1 to 1, indicating the strength and direction of the linear relationship between the markers. The concentrations of lipid profile (i.e., TC, TG, LDL, and VLDL) or cardiac profile (i.e., CK-MB, CPK, troponin T, and troponin I) were significantly elevated in all MI patients. However, the HDL level (P = 0.001) was decreased.

According to obtained results, reactive oxygen species (ROS) might be the causative agent of MI. Therefore, if an antioxidant medication is used as administrative content, it would be helpful for the treatment of MI and a lead mark for pharmaceutical companies in drug designing for MI patients.
