Introduction: Apolipoprotein B (Apo B) and apolipoprotein A-I (Apo-I) are cholesterol transporters playing an important role in lipid metabolism. Apo B and A-I represent the total atherogenic and non-atherogenic particles respectively. Hence, their ratio – Apo B/A-I has been strongly associated with various cardiovascular events. Aim: To compare the diagnostic efficacy of apolipoproteins with conventional lipids for coronary heart disease. Materials and Methods: There were 295 individuals with or without coronary heart disease were enrolled in the study. The demographic details along with clinical investigations of serum lipid parameters, Apo B and Apo A-I levels were obtained and recorded. Study Design: It was a single centre, prospective observational study of 295 individuals of both the genders (235 males and 60 females) with or without coronary artery disease. Statistical Analysis: A comparison of parametric values between two groups was performed using student’s t-test. Non-parametric analysis of the continuous data was performed using Mann-Whitney U test. Significance was taken as two tailed p<0.05. Results: In study population, 221(74.92%) had coronary heart disease (CHD) and 74(25.08%) were normal. Statistically significant differences were found in the levels of apo B/apo A-I ratio (p=0.009), and Apo A-I (p=0.001) between two groups. The other lipid parameters and ratios such as cholesterol, triglyceride, HDL-C, LDL-C, nonHDL-C cholesterol, VLDL, Total lipid, Apo-B, LDL-C/HDL-C and TC/HDL-C were not found to be significant. Conclusion: The present study shows that Apo B/A-I possesses superior diagnostic efficacy for coronary heart disease as compared to conventional lipid parameters and could be effectively used in clinical practice. |
