  • We investigated the relationship of apoB/apoA1 ratio and coronary heart disease (CHD) in persons who were overweight or obese. The subjects were divided by the body mass indexes (BMI) into the normal weight group (n=397, BMI<24 kg/m2) and the overweight group (n=400, BMI>24 kg/m2). Our results showed that the over-weight group had higher blood pressure [(130.15±19.01) mmHg vs (123.66±18.70) mmHg] and higher levels of blood sugar [(7.09±2.89) mmol/L vs (6.21±2.59) mmol/L], triglyceride [(1.93±1.19) mmol/L vs (1.44±0.85) mmol/L], total cholesterol [(4.26±1.06) mmol/L vs (4.09±0.99) mmol/L], low-density lipoprotein cholesterol (LDL-C) [(2.56±0.75) mmol/L vs (2.39±0.72) mmol/L], and apoB [(0.83±0.27) mg/L vs (0.78±0.23) mg/L], and a higher apoB/apoA1 ratio (0.83±0.27 vs 0.75±0.25) and lower levels high-density lipoprotein cholesterol [(1.10±0.26) mmol/L vs (1.21±0.31) mmol/L] and apoA1 [(1.04±0.20) mg/L vs (1.08±0.22) mg/L] than those of the normal weight group (all P < 0.05). The prevalence of CHD in the over-weight group in the lowest LDL quar-tile was almost twice greater than that of the highest apoB/apoA1 quartile, compared with the subjects in the low-est apoB/apoA1 quartile. The higher apoB/apoA1 quartile was in agreement with the higher prevalence of CHD. In the overweight and obesity group, the area under ROC curve (AUC) was the highest for apoB/apoA1 (0.655). The cut-off point of apoB/apoA1 for optimal sensitivity and specificity was at 0.80, with a sensitivity of 57.19% and a specificity of 71.72%. In conclusion, apoB and apoA1 were simple clinical indicators, and the apoB/apoA1 ratio was closely related with CHD in overweight and obese patients. The apoB/apoA1 ratio may provide some useful information in the differential diagnosis.
