RESUMEN
Objective: To evaluate and compare the serum levels of visfatin, interleukin-6 and lipid profile in non-obese and obese male patients with coronary artery disease
Study Design: Observational, comparative study
Place and Duration of Study: Punjab Institute of Cardiology and Lahore General Hospital, Lahore, from July to December 2013
Methodology: The participants included 20 non-obese group I with coronary artery disease [CAD] and 20 obese males group II with coronary artery disease [angiographically confirmed]. All the participants were in the age group of 35 - 55 years being non-smokers and non-diabetic. Serum visfatin and interleukin-6 levels were analysed by Enzyme Linked Immunosorbent Assay [ELISA]. Lipid profile was also evaluated. Results were compared with T-test and Mann Whitney U test. The values were considered significant at 0.05 level of significance
Results: Serum visfatin 9.05 versus 3.9 ng/ml and interleukin-6 12.80 versus 0.60 pg/ml levels were significantly [p-value < 0.001 of both] raised in the obese CAD group as compared to non-obese with CAD. Lipid profile also showed raised levels of total serum cholesterol, low density lipoproteins, triglycerides, very low density lipoproteins and low levels of high density lipoproteins in obese group
Conclusion: Significantly raised levels of serum visfatin and interleukin-6 indicate adipose tissue as an imperative source of these adipocytokines involved in inflammation in CAD. Altered lipid profile also seen in obese patients with CAD
