Objective: Diabetes is a major worldwide health problem, leading to markedly increased mortality and serious morbidity. It is characterised by chronic hyperglycemia resulting from a diversity of aetiologies and environmental and genetic factors acting together. Type 2 diabetes mellitus itself leads to dyslipidemia like elevated triglyceride levels and low HDL levels, which are known risk factors for coronary artery disease (CAD). Increased lipoprotein (a)[Lp(a)] concentrations are predictive of CAD. The__ampersandsignnbsp;study was designed to estimate serum lipoprotein (a) and glycosylated hemoglobin (HbA1c) in south Indian patients with type 2 diabetes mellitus and compare them with healthy controls. Material and Methods: The study included 50 patients of type 2 diabete mellitus and 50 age and sex matched controls. Fasting venous blood sample was analysed for fasting blood glucose(FBS), glycated hemoglobin (HbA1c), lipid profile and serum Lp(a). Statistical analysis was done using student t test. Results: The serum Lp(a) and HbA1c levels were significantly elevated in type 2 diabetics compared to healthy controls (p__ampersandsignlt;0.001). There was significant elevation in the levels of FBG ,total cholesterol, total triglyceride, LDL cholesterol and TC/HDLcholesterol ratio in type2 diabetics compared to the control group(p__ampersandsignlt;0.05). Conclusion: Diabetic patients have higher levels of serum Lp(a) and HbA1c compared to healthy controls. Serum Lp(a) associated with lipid abnormalities - high total cholesterol, high triglyceride ,high LDL and low HDL makes diabetics prone for CAD.__ampersandsignnbsp;
