Abstract :
Introduction: A myocardial infarction (MI), often known as a heart attack, occurs when blood supply to a region of the heart is reduced or stopped, resulting in heart muscle damage. One of the elemental mechanisms responsible for the development of myocardial infarction is oxidative stress. The study aims to assess the Oxidative stress and Troponin I levels in patients with myocardial infarction (MI) and compare them with the level of these parameters in healthy controls. An attempt has been made to find if there is any correlation between oxidative stress and Troponin I levels in patients with myocardial infarction.
Materials and Methods: The Cardiac marker Troponin I and the marker of oxidative stress malondialdehyde were estimated in 30 patients with myocardial infarction and 30 healthy individuals who acted as controls.
Results: A statistically significant difference was observed between Troponin I and MDA in patients with MI as compared with controls. A significant positive correlation was also observed between MDA and Troponin I levels.
Conclusion: In our study there wasa significant positive correlation between oxidative stress and Troponin I. Further studies with a larger number of subjects will be needed to find if oxidative stress plays a role in the pathogenesis of myocardial infarction.
