Aim: To evaluate serum Interleukin-6, and lipids as predictors of cardiovascular diseases (CVD) in obese and non obese male patients of coronary artery disease (CAD).

Methodology: It was cross-sectional comparative study. Serum Interleukin-6 and lipid profile was determined in non diabetic, non smoker and non hypertensive age matched obese and non obese male patients of CAD and healthy subjects. Sixty male subjects were divided equally into groups. Group 1, healthy controls (n=20), group 2, non obese male patients with CAD (n=20) and group 3 included Obese male patients with CAD (n=20). The serum was assayed for lipid profile and interleukin-6 .

Results: Age matched healthy and patients were non diabetics, non hypertensive and non smoker with altered lipid profile in obese and non obese male patients with coronary artery disease. Patients have high serum cholesterol, low density cholesterol(LDL-C), Triglyceride(TG,) very low density lipoprotein(VLDL) and interleukin-6. The High density lipoprotein was lowered in both obese and non obese male patients with CAD. Significant positive correlation was observed in CAD group of IL-6 with TC (rho= 0.405, p= 0.009*) , with TG (rho= 0.639, p= 0.000*) ,with LDL (rho= 0.398, p= 0.002*), with VLDL (rho= 0.315, p= 0.014*). Significant negative correlation was observed in CAD group of IL-6 with HDL (rho= -0.565, p= 0.000*) Significant positive correlation was observed in CAD group of IL-6 .Significant positive correlation of IL-6 was observed with AI (rho= 0.602, p= 0.000*).

Conclusion: Dyslipidemia, Raised interleukin-6 and strong positive correlation of Atherogenic index with IL-6 are independent risk factors for CVD; using Atherogenic risk ratios as a screening tool for the estimation of CVD risk is useful in patients with CAD.
