RESUMO

Objective: Patients with type 2 diabetes mellitus usually have multiple cardiovascular disease risk factors. The objective of this study was to examine the severity and associated risk factors in coronary artery disease patients with type 2 diabetes mellitus. Methods: Two hundred and five coronary artery disease patients with type 2 diabetes mellitus and 205 age-, gender- and smoking-matched coronary artery disease patients without type 2 diabetes mellitus were recruited from the Department of Cardiology of our hospital. Demographic and clinical data were collected for all participants. Severity of coronary artery disease was assessed using Gensini scoring system, the number of diseased coronary arteries, and the extent of coronary stenosis. Results: Coronary artery disease patients with type 2 diabetes mellitus had higher Gensini scores (p < 0.01), more numbers of diseased coronary arteries (p < 0.001), and higher degrees of coronary stenosis (p = 0.05) than coronary artery disease patients without type 2 diabetes mellitus. The plasma levels of very low-density lipoprotein cholesterol (p < 0.001) and triglycerides (p < 0.001) were also higher in coronary artery disease patients with type 2 diabetes mellitus than in coronary artery disease patients without type 2 diabetes mellitus. In coronary artery disease patients with type 2 diabetes mellitus, very low-density lipoprotein cholesterol was positively correlated with Gensini scores (r = 0.15, p = 0.03), the number of diseased coronary arteries (r = 0.15, p = 0.04), and the extent of coronary stenosis (r = 0.14, p = 0.05) by partial correlation analysis after controlling for other lipid parameters, and independently associated with Gensini scores (beta = 0.18, p = 0.02) and the number of diseased coronary arteries (odds ratio = 2.09, p = 0.05) after adjusting for other cardiovascular risk factors in the following multiple regression analysis. Conclusion: Very low-density lipoprotein cholesterol may represent a marker for the severity of coronary artery disease and be a target for the treatment in diabetic patients. Further research is needed to determine whether very low-density lipoprotein cholesterol plays a causal role of coronary artery disease in diabetic patients.

RESUMO

BACKGROUND: Studies on the associations of the adenosine triphosphate-binding cassette transporter A1 gene (ABCA1) rs2230806, rs2230808, and rs2066714 polymorphisms with plasma lipid levels have reported apparently conflicting findings. This meta-analysis aimed to clarify the relationships between the 3 polymorphisms and fasting lipid levels. METHODS: A comprehensive search of the literature was carried out by using the databases including Medline, Google Scholar, Web of Science, Embase, Cochrane Library, CNKI, Wanfang, and VIP. The studies that presented mean lipids and standard deviations or standard errors according to the rs2230806, rs2230808, and/or rs2066714 genotypes were examined and included. The random effects model was used. Standardized mean difference and 95% confidence interval were used to assess the differences in lipid levels between the genotypes. Heterogeneity among studies was tested by Cochran's χ-based Q-statistic, and Galbraith plots were used to detect the potential sources of heterogeneity. Publication bias was assessed by Begg's rank correlation test as well as funnel plots. RESULTS: Sixty-two studies (48,452 subjects), 12 studies (9853 subjects) and 14 studies (10,727 subjects) were identified for the rs2230806, rs2230808, and rs2066714 polymorphisms, respectively. A dominant model was used for all the polymorphisms in this meta-analysis. The A allele carriers of the rs2230806 polymorphism had higher levels of high-density lipoprotein cholesterol (HDL-C) (P <.001), and lower levels of low-density lipoprotein cholesterol (LDL-C) (P =.03) and triglycerides (TG) (P <.01) than the non-carriers. The A allele carriers of the rs2230808 polymorphism had higher levels of total cholesterol (TC) (P <.001) than the non-carriers. The G allele carriers of the rs2066714 polymorphism had higher levels of TC (P <.01) and HDL-C (P = .02) than the non-carriers. CONCLUSION: The ABCA1 rs2230806, rs2230808, and rs2066714 polymorphisms are significantly associated with plasma lipid levels in the present meta-analysis.

RESUMO

BACKGROUND: Dyslipidaemia is a major risk factor for coronary heart disease (CHD). Danhong and Huangqi injections, two traditional Chinese medicine prescriptions, have been widely studied regarding their lipid-lowering properties. However, the results were inconsistent and inconclusive. Thus, we conducted this meta-analysis of clinical controlled trials to clarify the lipid-lowering effects of Danhong and Huangqi injections. METHODS: The databases including PubMed, Google Scholar, Web of Science, Cochrane Library, Wanfang Database, CNKI and VIP were searched. The following information was obtained from each study: first author, age, gender, ethnicity, health condition, treatment dose, treatment duration, sample size, mean and standard deviation or standard error of lipid variables before and after treatment. The changes in lipid levels from pre- to post-treatment were calculated and compared between the control groups and the treatment groups in this meta-analysis. RESULTS: Forty-four studies (5021 subjects) and 7 studies (542 subjects) were respectively identified for Danhong and Huangqi injections. Compared with the control groups, Danhong injection yielded a significant reduction in triglycerides (TG) [standardized mean difference (SMD) = - 0.76, 95% confidence interval (CI) = (- 0.91, - 0.61), P <  0.001], total cholesterol (TC) [SMD = - 1.29, 95% CI = (- 1.56, - 1.03), P <  0.001] and low-density lipoprotein cholesterol (LDL-C) [SMD = - 0.76, 95% CI = (- 0.93, - 0.59), P <  0.001], and a significant elevation in high-density lipoprotein cholesterol (HDL-C) [SMD = 0.70, 95% CI = (0.41, 0.98), P <  0.001]. Regarding Huangqi injection, it yielded a significant reduction in TC [SMD = - 1.13, 95% CI = (- 2.09, - 0.16), P = 0.02] and marginally in TG [SMD = - 1.27, 95% CI = (- 2.53, 0.00), P = 0.05] comparing with the control groups. CONCLUSIONS: Danhong injection can effectively decrease the plasma levels of TG, TC and LDL-C, and increase HDL-C levels. Huangqi injection also has significant effects on TG and TC reduction, but not as powerful as Danhong injection.

RESUMO

BACKGROUND: The associations of the apolipoprotein B gene (APOB) rs693 and rs17240441 polymorphisms with plasma levels of APOB and lipids have been widely explored, but the results were inconclusive. This meta-analysis aimed to clarify the associations of the rs693 and rs17240441 polymorphisms with fasting APOB and lipid levels. METHODS: Sixty-one studies (50,018 subjects) and 23 studies (8425 subjects) were respectively identified for the rs693 and rs17240441 polymorphisms by searching in PubMed, Google Scholar, Web of Science, Cochrane Library, Wanfang, VIP and CNKI databases. The following information was collected for each study: first author, age, gender, ethnicity, health condition, sample size, genotyping, lipid assay method, mean and standard deviation or standard error of APOB and lipid variables by genotypes. A dominant model was used for this meta-analysis. RESULTS: The carriers of the rs693 variant allele (T) had higher levels of APOB [standardized mean difference (SMD) = 0.26, 95% confidence interval (CI) = 0.16-0.36, P < 0.01], triglycerides (TG) (SMD = 0.12, 95% CI = 0.05-0.20, P < 0.01), total cholesterol (TC) (SMD = 0.24, 95% CI = 0.17-0.30, P < 0.01) and low-density lipoprotein cholesterol (LDL-C) (SMD = 0.22, 95% CI = 0.14-0.30, P < 0.01), and lower levels of high-density lipoprotein cholesterol (HDL-C) (SMD = -0.06, 95% CI = -0.11-0.01, P = 0.01) than the non-carriers. The carriers of the rs17240441 deletion allele had higher levels of APOB (SMD = 0.13, 95% CI = 0.06-0.20, P < 0.01), TC (SMD = 0.17, 95% CI = 0.07-0.26, P < 0.01) and LDL-C (SMD = 0.15, 95% CI = 0.07-0.23, P < 0.01) than the non-carriers. CONCLUSIONS: The rs693 polymorphism is significantly associated with higher levels of APOB, TG, TC and LDL-C, and lower levels of HDL-C. The rs17240441 polymorphism is significantly associated with higher levels of APOB, TC and LDL-C. Further studies are needed to elucidate the underlying mechanisms.
