Estimation of the oxidative stress status and lipid profile in ischemic heart disease in male patients

Objective: The present study is carried out to the measurement of lipid peroxidation end product, malondialdehyde (MDA) in addition to estimate the lipid profile parameter both in control subjects and in ischemic heart diseases (IHD) patients. Methodes: Sixty eight patients with ischemic heart diseases including stable angina (SA), unstable angina (UA) and myocardial infarction (MI) (aged 40-69 years) were involved in the present study during their admission to Al- Sader Teaching Hospital / Al- Najaf Al- Ashraf. Age matched twenty two healthy men were included as control group. All blood samples were taken early morning from fasting subjects. Ischemic heart diseases patients were divided into smoker and nonsmoker groups, to observe the effect of smoking on lipid peroxidation in coronary heart disease patients. The measured parameters in serum included: total cholesterol (TC) and it's different fractions, triglycerides (TG) and malondialdehyde (MDA). Results: Malondialdehyde and lipid parameters were found significantly high (P< 0.05) with the exception of high-density lipoprotein cholesterol which was not significantly different among groups in ischemic heart diseases patients. Smokers with coronary heart disease showed significantly increased (P< 0.05) malondialdehyde levels as compared to nonsmokers with coronary heart disease. Conclusion: Malondialdehyde elevation in IHD patients indicating a possible role of oxidative stress processes in the pathophysiology of the heart diseases. Smoking has adverse effects on lipid profile and MDA.
