Is the ratio of apoB/apoA-1 the best predictor for the severity of coronary artery lesions in Chinese diabetics with stable angina pectoris? An assessment based on Gensini scores

  • Background There is a paucity of data about the best lipid ratio predicting the severity of coronary artery disease (CAD) in patients with diabetes mellitus. We determined the relationship between five conventional lipid ratios and the extent of coronary artery lesions in Chinese Type 2 diabetics with stable angina pectoris (SAP). Methods A prospective cohort study within 373 Type 2 diabetic patients diagnosed with stable CAD by coronary angiography was performed. All patients were classified into three groups according to the tertiles of Gensini scores (GS, low group n = 143; intermediate group 8–28 points, n = 109; high group > 28 points, n = 121). Association between the ratios of apolipoprotein (apo) B and apoA-1, total cholesterol and high density lipoprotein cholesterol (TC/HDL-C), triglycerides and HDL-C (TG/HDL-C), low density lipoprotein cholesterol and HDL-C (LDL-C/HDL-C), Non-HDL-C/HDL-C and GS were evaluated using the receivers operating characteristic (ROC) curves and multivariate logistic regression models. Results The ratio of apoB/apoA-1, TC/HDL-C, LDL-C/HDL-C, and Non-HDL-C/HDL-C were correlated with Gensini scores. Area under the ROC curves for predicting high Gensini scores in the ratios of apoB/apoA-1, TC/HDL-C, LDL-C/HDL-C and Non-HDL-C/HDL-C were 0.62, 0.60, 0.59 and 0.60, respectively (P Conclusion Compared with other lipid parameters, the ratio of apoB/apoA-1 appears to be more significantly correlated with the extent of coronary artery lesions in Chinese diabetics, but it was not an independent predictor in these settings.
