title: Oxidative stress and antioxidant status in normolipidemic AMI patients.
abstract: The objective of the study was to observe the correlation between oxidative stress and antioxidants in myocardial infarct patients with normal lipid profile. In the present study investigation of lipid peroxidation and antioxidants were done in patients. This study was carried out on 165 AMI patients, (123 males and 42 females). The control group consisted on 165 normal healthy age-sex matched subjects (123 males and 42 females). Levels of Superoxide dismutase, Glutathione Peroxidase, Catalase, Malondialdehyde and Conjugated dienes were measured. The study found Superoxide dismutase, Glutathione Peroxidase, Catalase were significantly lower in activities (p<0.001) in AMI patients compared to controls. The markers of lipid peroxidation namely Malondialdehyde and Conjugated dienes were higher in AMI patients as compared to controls (p<0.001). The present study is clearly suggestive of increased oxidative stress in AMI patients. Oxidative stress appears as an etiological factor for myocardial infraction as a consequence the free radical scavengers levels are lowered in AMI patient.
