The aim of the study is to correlate Atherogenic Index of Plasma {AIP = log (TGL/HDL)} and with Lipoprotein(a) concentrations in diabetic patients compared to healthy subjects. Materials and Methods: The study included 30 non-diabetic subjects and 30 diabetic patients. Lipoprotein(a) [Lp (a)] was estimated by Immunoturbidimetry and the parameters Triglyceride and High Density Lipoprotein (HDL) by their respective methods in Biochemistry Auto-analyzer. Results: It was found that, there is a

... ive correlation of Lp(a) with the AIP. Conclusion: It is summarized that, the lipoprotein ratio like AIP shall be accepted as a better indicator of cardio-vascular risk other than taking into account one of the lipoproteins as such. Estimating Lipoprotein(a) is costlier compared to the other lipoproteins, which makes it an objectionable parameter by the patients themselves. In the future, we would thereby, insist the rationale behind estimating the lipoprotein ratios as better markers of assessing cardio-vascular risks.
