ABSTRACT
The aim of this study was to evaluate the level of auto antibody against oxidized LDL in myocardial infracted (MI) patients and normal healthy subjects of West Bengal (India) and to establish it to be also a cofactor for MI. Patients and Methodology : This study was carried out on 285 patients with MI as well as 75 healthy volunteers of comparable age and gender as control group. Blood was collected immediately after admission of the patients. Auto antibody against oxidized LDL, Nitric Oxide and malondialdehyde (MDA) were measured in all groups. Results : Mean serum level of auto antibody against oxidized LDL, MDA, total Cholesterol and LDL Cholesterol levels (118 ± 9.0, 7.4 ± 1.3, 233 ± 30, and 145 ± 38) were significantly (p<0.05) higher in MI patients when compared with control subject. The mean serum levels of nitric oxide (NO) and HDL, cholesterol were significantly (p<0.05) lower as compared to control group. Conclusion : Significantly high level of auto antibody against oxidized LDL associated with high level of MDA, total cholesterol and decreased level of NO and HDL cholesterol appear to be the factors responsible for the increase risk of coronary artery disease i.e., myocardial infarction in the population of West Bengal, India.
