Oxidized LDL cholesterol promotes atherosclerosis in many ways.36 Free radicals are generated during the metabolism of substance like fatty acids. Antioxidants of clinical importance in cardiovascular diseases, which are scavengers37 of free radicals estimated at different time points in both arms, remained statistically comparable. The normal values of these enzymes are not well established in this particular population but we compared baseline level with enzymes levels at different time intervals to assess the status of redox potential.
