Methods A total of 172 elderly patients who underwent coronary angiography were divided into CAD group （n = 128） and non-CAD group （n = 44） according to the results of coronary angiography. Serum FFAs and lipid levels were measured and the Gensini score were calculated. Results No matter the differences between age, gender and the usage of stat- ins or not, there was no statistical significance in FFAs levels （P 〉 0.05）. In terms of the Gensini score, it was higher in patients aged 70-79 years than in patients 60-69 years old [15.00 （5.00, 34.00） vs. 10.00 （2.00, 24.00）, P 〈 0.05], higher in men than women [14.00 （4.00, 34.00） vs. 7.00 （2.50, 19.75）, P 〈 0.05], and higher in patients on statins [13.50 （4.25, 33.50）vs. 6.50 （2.00, 18.00）, P 〈 0.05]. The serum FFAs lev- els [449.50 （299.00, 624.75） mEq/L vs. 388.00 （258.50, 495.25） mEq/L, P 〈 0.05J and Gensini score [17.50 （8.00, 41.75） vs. 1.00 （0, 5.00）, P 〈 0.05] were higher in the CAD group than in the non-CAD group. In the CAD group, there was no statistical significance in FFAs levels among patients with different numbers of diseased coronary vessels （P 〉 0.05）. Furthermore, the FFAs levels were positively correlated with the Gensini score （r = 0.394, P = 0.005）. Regression analysis showed that the FFAs levels were related to the Gensini score independently after adjusting for the other risk factors. Conclusions The serum FFAs levels were associated with the Gensini score in elderly patients with CAD. It might indicate FFAs as a biomarker predicting the severity of coronary artery lesions.展开更多

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 diag- nosed 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 〈 8 points 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, respec- tively （P 〈 0.005 for all）. According to multivariate logistic regression analysis after adjusted with demographic characteristic and other lipid parameters, the ratio of apoB/apoA-1 is qualified as an independent discriminator for the severity of CAD. However, after fiu-ther adjusting different baseline variables, such as left ventricular ejective fraction, hemoglobin Alc, leukocytes count and serum creatinine, none of the above lipid ratios remained. Conclusions 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.展开更多

Methods A total of 4206 euthyroid patients were consecutively enrolled and di- vided into CAD group （n = 3306） and non-CAD group （n = 900）. All patients underwent coronary angiography （CAG）. Gensini score （GS） was used to determine the severity of coronary artery stenosis. Severe CAD was defined as GS 〉 32 and mild CAD was defined as GS 〈 32. Logistic regression analysis and linear regression analysis were conducted to determine the association of FT3 with CAD in patients with different gender and ages. Results Concentration of FT3 was lower in patients with CAD than that in angiography-normal control group （P 〈 0.05）. In addition, concentration of FT3 was lower in severe CAD than that in mild CAD. After adjusting for traditional cardiovascular risk factors and potential confounders, FT3 was negatively correlated with the presence of CAD, but not in the old patients （〉 65 years old）. Mul- tivariable linear regression analysis showed that FT3 was negatively associated with GS in male and young patients with stable CAD, but not in the old patients. Conclusions Low FT3 within normal range was negatively associated with the presence and severity of CAD in young patients, but not in the old ones. Further studies are needed to confirm our findings.展开更多
