Abstract

Introduction: Endothelial dysfunction (ED) is a well known initial stage of atherosclerosis and cardiovascular disease (CVD) in general population. Recently studies shown increased HbA1c is a marker for cardiovascular risk in subjects with diabetes and without diabetes. Atherogenic index of plasma (AIP) is another risk factor for cardiovascular events. Hence, the study has been designed to assess the correlation of HbA1c with AIP and ED in type-2 diabetic subjects to forecast risk of cardiovascular events.
Materials and Methods: Hundred subjects are enrolled into study with the age of 38 to 58 years, among these 50 were type 2 diabetic subjects and 50 were healthy controls. HbA1c was estimated by immuno-turbidimetric method. Nitric oxide (NO) was measured by kinetic cadmium reduction method and AIP was calculated by standard formula Log (triglyceride/HDL-c). ‘Kruskal Wallis’ test was used to perform statistical variables between the study groups. The association between the variables was executed by “Pearson correlation test”.
Result: HbA1c level was shown to be significantly higher in type-2 diabetic subjects than healthy controls. Significant lower level of NO was observed in type-2 diabetic subjects than healthy controls. AIP level was significantly higher in type-2 diabetic subjects than healthy controls. The present study also observed significant correlation of HbA1c with NO and AIP.
Conclusion: We have found that HbA1c has significant correlation with NO and AIP. Therefore, estimation of HbA1c may be a predictable marker for cardiovascular events in type-2 diabetic subjects.
