BACKGROUND:Diabetes mellitus (DM) is associated with coronary artery disease (CAD) progression. Although previous studies have demonstrated the association of lipid and lipoprotein ratios with CAD, no data are currently available concerning the relationship between lipid and lipoprotein ratios and the severity of new on-set CAD in diabetics. Therefore, the aim of the present study was to investigate the usefulness of lipid and lipoprotein ratios in predicting the severity of CAD in patients with type 2 DM (T2DM).METHODS:A total of 380 consecutive T2DM patients with new on-set CAD were enrolled in the present study. Then, they were classified into the three groups according to Gensini score (GS) tertiles. The relationship between lipid and lipoprotein ratios currently used and the GS was investigated.RESULTS:Positive correlations of natural log-transformed GS (lnGS) with apolipoprotein B to apoA-I ratio (apoB/apoA-I), non-high-density lipoprotein cholesterol to apoA-I ratio (non-HDL-C/apoA-I), and low-density lipoprotein cholesterol to apoA-I ratio (LDL-C/apoA-I) were found (r = 0.18, 0.13, 0.12, respectively, all P < 0.05). Multivariate logistic analysis indicated apoB/apoA-I as the strongest predictor for high GS (OR = 5.67, 95% CI: 1.45-23.92, P = 0.003). Area under receivers operating characteristic curve of apoB/apoA-I was 0.63 (95% CI: 0.60-0.66, P = 0.001) for predicting high GS. The optimal cutoff value of apoB/apoA-I to predict high GS was 0.72 with the sensitivity of 61.2% and the specificity of 62.1%.CONCLUSIONS:Lipid and lipoprotein ratios might be useful for predicting the severity of new on-set CAD in T2DM patients, and the apoB/apoA-I appeared as the most significant predictor in this population.

AIM:To investigate the usefulness of the plasma big endothelin-1 (big ET-1) level in predicting the severity of new-onset stable angiography-proven coronary artery disease (CAD).METHODS:A total of 963 consecutive stable CAD patients with more than 50% stenosis in at least one main vessel were enrolled. The patients were classified into the three groups according to the tertile of the Gensini score (GS, low GS ＜20, n=300; intermediate GS 20-40, n=356 and high GS ＞40, n=307), and the relationship between the big ET-1 level and GS was evaluated.RESULTS:The plasma levels of big ET-1 increased significantly in association with increases in the GS tertile (p=0.007). A multivariate analysis suggested that the plasma big ET-1 level was an independent predictor for a high GS (OR=2.26, 95%CI: 1.23-4.15, p=0.009), and there was a positive correlation between the big ET-1 level and the GS (r=0.20, p=0.000). The area under the receiver operating characteristic curve (AUC) for the big ET-1 level in predicting a high GS was 0.64 (95% CI 0.60-0.68, p=0.000), and the optimal cutoff value for the plasma big ET-1 level for predicting a high GS was 0.34 fmol/mL, with a sensitivity of 62.6% and specificity of 60.3%. In the high-big ET-1 level group (≥0.34 fmol/mL), there were significantly increased rates of three-vessel disease (43.6% vs. 35.4%, p=0.017) and a high GS [31 (17-54) vs. 24 (16-44), p=0.001] compared with that observed in the low-big ET-1 level group.CONCLUSIONS:The present findings indicate that the plasma big ET-1 level is a useful predictor of the severity of new-onset stable CAD associated with significant stenosis.

The objective of the study was to investigate the usefulness of serum lipoprotein(a) level in predicting the severity of new on-set coronary artery disease in type 2 diabetics. A total of 1254 new on-set, consecutive coronary artery disease patients were classified into two groups: diabetes group (n = 380) and non-diabetes group (n = 874). The relationship between serum lipoprotein(a) levels and the severity of coronary artery disease assessed by Gensini score was analysed. Data showed that the diabetes group had higher serum triglyceride and high sensitivity C-reactive protein levels but lower high-density lipoprotein cholesterol levels (all p < 0.05). The multivariate logistic regression analysis suggested that lipoprotein(a) was an independent predictor for high Gensini score (odds ratio = 1.82, 95% confidence interval: 1.10-3.12, p = 0.029) after adjusting for traditional cardiovascular risk factors. Additionally, lipoprotein(a) levels were positively correlated with Gensini score (rho = 0.15, p = 0.014) and significantly elevated according to the tertiles of Gensini score (p = 0.008) in diabetics. However, no such results were observed in non-diabetics. Our data indicate that lipoprotein(a) is an independent predictor for the severity of new on-set coronary artery disease patients accompanied by type 2 diabetes, suggesting that these patients may benefit from lipoprotein(a) management in clinical assessment.

AIM:The usefulness of the white blood cell (WBC) count and neutrophil-to-lymphocyte ratio (NLR) in predicting the severity of stable coronary artery disease (CAD) has not been sufficiently evaluated, particularly based on strict coronary assessments. The aim of the present study was to investigate the WBC count and NLR in predicting the severity of angiographically proven CAD.METHODS:A total of 2,976 CAD patients and 571 non-CAD patients were consecutively enrolled, and the CAD patients were classified into the three groups according to the tertile of the Gensini score (GS, low GS<18, n=989; intermediate GS 18-41, n=995 and high GS>41, n=992). The efficacy of the WBC count and NLR in predicting the risk and severity of CAD as well as the correlations between these markers and the GS were analyzed. A receiver operating characteristic (ROC) curve analysis was also performed.RESULTS:The NLR was found to be an independent predictor of both the presence of CAD (OR=1.18, 95%CI: 1.09-1.27, p=0.009) and a high GS (OR=1.10, 95%CI: 1.01-1.16, p=0.032). In addition, there were mild positive correlations between the GS and the NLR, WBC and proportions of neutrophils and monocytes. In the ROC curves analysis, the NLR was found to have the largest area under the curve (AUC=0.63, 95%CI: 0.59-0.67, p=0.000), with an optimal cut-off value of 2.04 (sensitivity: 62.1%, specificity: 54.8%) for predicting a high GS.CONCLUSIONS:The NLR is a valuable independent predictor of the severity of CAD assessed according to the GS. In particular, an NLR of >2.04 indicates a higher risk of CAD and greater severity of CAD lesions.

OBJECTIVE:Although the study on the relationship between ABO blood groups and coronary atherosclerosis has a long history, few data is available regarding ABO to severity of coronary atherosclerosis in a large cohort study. Therefore, the present study aimed to investigate the relation of the ABO blood groups to the severity of coronary atherosclerosis assessed by Gensini score (GS) in a large Chinese cohort undergoing coronary angiography.METHODS:A total of 2919 consecutive patients undergoing coronary angiography were enrolled, and their baseline characteristics and ABO blood groups were collected. The GS was calculated as 1st tertile (0-10), 2nd tertile (11-36), 3rd tertile (>36) according to angiographic results. The relation of the ABO blood groups to GS was investigated.RESULTS:The frequency of blood group A was significantly higher in the upper GS tertiles (24.4% vs. 28.2% vs. 29.5%, p = 0.032). Multivariable linear regression analysis revealed that blood group A was independently associated with GS (β = 0.043, p = 0.017). Likewise, multivariable logistic regression analysis showed that group A remained significantly associated with mid-high GS (OR = 1.44, 95% CI 1.16-1.80, p = 0.001), and the group O was showed as a protective factor (OR = 0.77, 95% CI = 0.65-0.92, p = 0.004).CONCLUSION:In this large Chinese cohort study, the data indicated that there was an association between ABO blood groups and the severity of coronary atherosclerosis. Moreover, the blood group A was an independent risk factor for serious coronary atherosclerosis.
