Background: High triglycerides (TG) and low High density Lipoproteins (HDL) are established coronary risk predctors (ratio of 3:1 being associated with definite increase in coronary risk). The TG/HDL ratio has also been established as a predictor of major cardio vascular events, insulin resistance and metabolic syndrome. However, the utility of the same in predicting worsening of peripheral vascular disease remains under-researched. Aims and Objectives: We aim at establishing TG/HDL ratio as a predictor of peripheral arterial disease in diabetic patients and to also explore the role of triglycerides and lipid lowering agents, in general, in modifying this risk. Materials and Methods: We carried out a cross sectional study enrolling Diabetes Mellitus patients with symptoms suggestive of peripheral vascular disease. We included 304 patients and analyzed their TG levels and TG/HDL ratios stratified as per age, gender and medical history. Relevant statistical analysis was carried out. Results: There was a difference in TG levels in men and women who developed serious peripheral vascular events with women having significantly elevated TG levels in comparison to men. The TG/HDL ratio was also found to be 8.06 in women and 7.88 in men. This was statistically significant in comparison to the control group. Conclusion: TG/HDL-C ratio, also known as atherogenic index, which is easily obtained by routine biochemical evaluation can be used to prognosticate incidence of peripheral arterial disease in addition to cardiovascular risk. This would serve as an easy Outpatient prognosticating and predictive factor for further assessment and patient education.
