Background: The present study was design to assess the level of altered lipid profile, lipoprotein sub fractions, oxidative stress and antioxidants in coronary artery disease with type-2 diabetes mellitus’s patients and non diabetic patients.
Methods: This case–control study included 300 subjects; out of which, 100 subjects were with normal blood glucose level and with normal ECG (Normal, N), 100 subjects were with normal blood glucose level and AMI (non-diabetic and AMI, N-AMI) and 100 subjects were with diabetes and AMI (Diabetic and AMI, D-AMI)
Results: D-AMI individuals had high level of total cholesterol (TC), triglycerides (TG), low density lipoprotein (LDL), and low level of high density lipoprotein (HDL) in comparison to N-AMI individuals. The cardiac markers such as Troponin I, creatine phosphokinase (CPK), creatine kinase-MB (CK-MB), aspartate aminotransferase (AST), lactate dehydrogenase (LDH), and C-reactive protein (CRP) levels were significantly increased in patients suffering from myocardial infarction with diabetes mellitus (DM) compared to patients of myocardial infarction without DM. The antioxidant superoxide dismutase (SOD) and glutathione (GSH) were lower in D-AMI patients than in N-AMI. However, levels of malondialdehyde (MDA) and catalase (CAT) were higher in D-AMI than in N-AMI controls.
Conclusion: Our study suggested that patients with D-AMI have elevated cardiac markers and reduced antioxidants levels as compared to N-AMI patient.
