Abstract Background Coronary Artery Disease (CAD) is caused by the blockage of the coronary arteries. it is argued that there has an association between the Interleukin-6 gene and the occurrence of atherosclerosis, coronary artery disease, Due to the short half-life and high variability of Interleukin-6 (IL-6), limited studies have been performed on the association of serum levels of interleukin-6 with coronary artery disease. The aim of this study is to investigate the relationship between IL-6 gene polymorphisms and coronary artery disease. Methods This study was conducted as a meta-analysis of selected articles with no lower time limit and upto March 2020. Articles related to the subject were obtained by searching several data sources,such as the SID, IranDoc, Scopus, Embase, Web of Science (ISI), PubMed, Science Direct, and Google Scholar databases. The heterogeneity of the studies was assessed using the I2 index in the Comprehensive Meta-Analysis software. Results The GG genotype of the IL-6174 G> C polymorphism with a 0.8 odds ratio tended to reduce the risk of CAD by 20%. The odds ratio of CAD in CG and GG genotypes were found to be 1.16 and 1.48 times respectively, indicating the increasing effect of these two genotypes. In the IL-6-572 C>G polymorphism, CG and GG genotypes increased the risk of CAD by 1.21 and 1.27 times respectively, and the CC genotype tended to reduce the risk of CAD by 15%, considering the odds ratio of 0.85. Conclusion This study showed a relationship between IL-6174G> C and Interleukin-6 (IL-6) 572 C>G genes and coronary artery disease. Moreover, the protective effects of GG genotype in IL-6 gene 174 G> C and CC genotype in IL-6 gene 572 C>G gene were reported. The study also confirmed that the CG and CC genotypes of the G>C IL-6174 gene have an increasing effect on coronary artery disease. Moreover, CG and GG genotypes in the IL-6 gene 572 C>G increased the risk of developing CAD. It should be noted that the increased risk of developing CAD was limited to meta-analytic studies in reported literatures.

Aim: The aim of this study was to assess the association between PEAR1 polymorphisms and ischemic clinical outcomes. Materials & methods: We searched the electronic database for articles on the relationship of PEAR1 SNPs and ischemic events in patients with coronary artery disease (CAD) up to October 2020. Results: A total of 9914 patients with CAD from six studies focusing on 12 SNPs of PEAR1 were included in this study. The A allele of rs12041331 were associated with ischemic events (odds ratio: 1.40; 95% CI: 1.04–1.88; p = 0.03). The AA homozygotes of rs2768759 was related to a higher risk of ischemic events than carriers of the C allele (odds ratio: 2.08; 95% CI: 1.09–3.97; p = 0.03). Conclusion: PEAR1 rs12041331 and rs2768759 are significantly associated with ischemic events in patients with CAD.

Introduction: Smoking is a well known risk factor for coronary artery disease (CAD). Moreover, controversial data suggest that the -174 G/C polymorphism on Interleukin-6 (IL-6) gene promoter (rs1800795) may represent an early marker of inflammatory activation, closely related to the initiation and evolution of atherosclerosis. However, no data exist concerning a combined effect of smoking and this IL-6 genetic variant on several aspects of inflammation and thrombosis, endothelial function and the presence of CAD. Methods: 646 subjects (361 non smokers) were subjected to appropriate genotyping. Endothelial function was assessed by the flow mediated dilatation (FMD) of brachial artery. IL-6 (pg/ml), Tumor Necrosis Factor-a (TNF-a) (pg/ml), high sensitivity CRP (hsCRP) (mg/l) and D-dimers (μg/l) were measured with appropriate methods. Results: An increased incidence of CAD was found among the carriers of the allele C, compared to GG homozygotes, (OR:1.59, CI:1.26-2.93, p=0.032) in smokers, while a decreased incidence was observed in non smokers (OR:0.42, CI:0.26-0.68, p<0.001), after adjustment for all risk factors for CAD. The C allele carriers, compared to GG homozygotes, were associated with significantly higher serum levels of IL-6 (3.09±1.4 vs 1.3±0.7), TNF-a (5.3±2.4 vs 2.57±1.8), hsCRP (2.09±0.9 vs 1.05±0.69) in smokers as well as in non smokers (IL-6: 2.62±1.2 vs 1.64±0.89, TNF-a: 3.57±1.67 vs 4.43±2.1, hsCRP: 1.84±0.82 vs 1.62±0.77), p<0.01 for all. Importantly, the C allele, compared to GG homozygotes, enhanced the expression of fibrinogen (488.3±115.1 vs 318.5±61.1 p<0.001) and D-dimers (513±313.4 vs 355.1±218.4, p=0.025) in smokers, while it down-regulated the expression of fibrinogen in non-smokers (351.9±84.5 vs 479.4±126.4, p<0.001). Impressively, the C allele carriers were correlated with significantly impaired endothelial function in the smoking group (3.9±2.7 vs 5.2±3.3, p=0.003), while no effect was observed among non-smokers (4.8±2.9 vs 5.04±2.6, p=0.64). Conclusions: The C allele of rs1800795 exerts a synergistic effect on smoking resulting to a significantly increased risk for CAD. This action is mediated by inflammatory and thrombotic mechanisms as well as by the impairment of endothelial function.

Abstract Introduction An association between a diagonal ear lobe crease (DELC) and cardiovascular disease, was first suggested by Sanders T. Frank in 1973(1). Since then, there have been numerous further studies that have investigated the association of ‘Frank’s Sign’ with carotid disease, cerebral vascular disease, and diabetic retinopathy. This review looks to see if there is a significant association between the presence of a DELC and coronary artery disease (CAD). Method Meta-analysis of selected studies, published between 1974 and 2017, using the PRISMA checklist(2). Results We included 12 studies in the pooled analysis, which included 2415 cases and 2545 controls. Our study found that patients with DELC, have an increased likelihood of having CAD (OR 4.61). Also, despite some previous studies suggesting that DELC was simply a result of age, all ten of the included studies that looked at this found that the relationship between DELC and CAD was independent of both age and other known cardiovascular risk factors. Conclusions We found that DELC is associated with CAD independently of other known cardiovascular risk factors, including age. Patients with DELC appear to have a substantially increased risk of CAD, and this may be higher for patients with bilateral DELC.

Introduction: End-stage renal disease requiring renal transplantation comprises a growing patient population at risk for cardiovascular disease (CVD) morbidity and mortality in large part due to accelerated atherosclerosis. Consequently, these patients are at even higher risk of major surgical CVD mortality. A paucity of research has addressed the posttransplantation CVD outcomes related to different treatment strategies in this patient population and therefore, there are no specific preoperative guidelines regarding management of coronary artery disease in this high-risk population undergoing renal transplantation. Objective: Through meta-analysis we compare coronary revascularization to medical management prior to renal transplantation in patients who are found to have significant obstructive coronary artery disease. Results: A total of 6 studies were deemed suitable out of 777 articles reviewed. This included 260 patients who received medical management and 338 who received coronary revascularization. There were 36 events in the revascularization and 57 events in the medical management group. One study only reported hazard ratios but no CVD outcomes. Comprehensive Meta-Analysis software was used to calculate pooled odds ratio with 95% confidence intervals (CI) for the fixed effects. The data is presented as forest plots. The pooled odds ratio with 95% CI for the fixed effects was 1.415 (95% CI 0.885–2.263), p = 0.147, indicating that there is no difference in CVD outcomes between pretransplant treatment strategy. This observation suggests that the CVD outcomes posttransplantation are not affected when optimal medical therapy is used instead of coronary revascularization.

Introduction: Pacemaker and ICD lead failure or vascular occlusion can require lead extraction. Predictors of a need for lead extraction due to venous occlusion are not well characterized. Hypothesis: Coronary artery disease (CAD) is an independent predictor of lead extraction due to venous occlusion. Methods: We performed a retrospective study of consecutive patients in a prospectively collected registry at a single center undergoing lead extraction due to either venous occlusion or lead failure from 10/2011 to 02/2020. Patients requiring lead extraction due to infection were excluded. Continuous variables are reported as mean ± standard deviation or total number reported as a percentage (%). Chi square test and logistic regression were used to estimate difference in rates and Odds Ratio. Statistically significant findings were identified with a p valve < 0.05. Results: Of 384 procedures included in the database, 131 patients met inclusion criteria for venous occlusion (17%) or lead failure (83%) (Table 1). Average age of the cohort was 55.1 ± 16.4 years and 51% were female. Baseline ejection fraction was 44.6 ± 15.5% and 19.7% of patients had NYHA class III or IV symptoms. 29.7% had a history of CAD. Average number of leads extracted was 1.3 ± 0.57 compared to 2.1 ± 0.82 leads in situ. Patients with CAD had a statistically significant increased risk for extraction as a result of venous occlusion Odds Ratio of 6.80, 95% CI 2.47-18.6, p = 0.0001. Conclusions: Identification of predictors of venous occlusion and risk stratification of these patients is an important component of procedural planning and shared decision making. CAD is a predictor of venous occlusion in patients undergoing lead extraction and should be assessed as a risk factor for complex lead management decisions. Further study is warranted to identify mechanisms by which this relationship can be used to predict need for extraction due to vascular occlusion.

Objective: The objective of this study was to investigate the association between proinflammatory cytokines in special, the interleukin-6 (IL-6), and insulin-like growth factor (IGF-1) levels in coronary artery disease (CAD) and type 2 diabetes mellitus (T2DM).Methods: This study was conducted from November 2017 to March 2018 in Anbar, Iraq. We studied a total of 90 individuals (46 men and 44 women) aged between 20 and 87 years. The samples were divided into four groups: CAD patients (n=23), T2DM patients (n=23), coronary artery disease and type 2 diabetes together in the same patient (n=23), and control group (n=21). The concentrations of IL-6 and IGF-1 were determined using a commercially available enzyme-linked immune sorbent assay.Results: The results of the present study showed that there were elevated serum levels of IL-6 and low levels of IGF-1 in all the tested groups, compared with the control. The difference was statistically significant at p<0.05. The results showed a positively correlated between IL-6 and IGF-1 in the CAD group and T2DM group, while it was a negative correlation between serum levels of IL-6 and IGF-1 in the T2DM+CAD group.Conclusion: Elevated levels serum of IL-6 predicts the development of CAD and T2DM. These data support a possible role for inflammation in diabetogenesis and complication of the cardiovascular disease. There is an inverse relationship between the levels serum of IGF-1 and increased risk of CAD and development of T2DM.

Background and Aim. Obesity is associated with an increased risk of cardiovascular disease and may be associated with more severe coronary artery disease (CAD); however, the relationship between body mass index [BMI (kg/m2)] and CAD severity is uncertain and debatable. The aim of this study was to examine the relationship between BMI and angiographic severity of CAD. Methods. Duke Jeopardy Score (DJS), a prognostic tool predictive of 1-year mortality in CAD, was assigned to angiographic data of patients ≥18 years of age (N=8,079). Patients were grouped into 3 BMI categories: normal (18.5–24.9 kg/m2), overweight (25.0–29.9 kg/m2), and obese (≥30 kg/m2); and multivariable adjusted hazard ratios for 1-year all-cause and cardiac-specific mortality were calculated. Results. Cardiac risk factor prevalence (e.g., diabetes, hypertension, and hyperlipidemia) significantly increased with increasing BMI. Unadjusted all-cause and cardiac-specific 1-year mortality tended to rise with incremental increases in DJS, with the exception of DJS 6 (p<0.001). After adjusting for potential confounders, no significant association of BMI and all-cause (HR 0.70, 95% CI .48–1.02) or cardiac-specific (HR 1.11, 95% CI .64–1.92) mortality was found. Conclusions. This study failed to detect an association of BMI with 1-year all-cause or cardiac-specific mortality after adjustment for potential confounding variables.

Lp(a) has been well known as an independent risk factor for coronary artery disease (CAD). TheLPAgene, as it encodes apo(a) of the Lp(a) lipoprotein particle, was associated with increased risk of CAD. The purpose of this study was to analyze the relationship between the polymorphisms ofLPAgene and CAD in Chinese Han population. Five SNPs (rs1367211, rs3127596, rs6415085, rs9347438, and rs9364559) in theLPAgene were genotyped using Sequenom MassARRAY time-of-flight mass spectrometer (TOF) in 560 CAD patients as case group and 531 non-CAD subjects as control group. The numbers of these two groups were from Chinese Han ancestry. The results showed that allele (P=0.046) and genotype (P=0.026) of rs9364559 in theLPAgene was associated with CAD. The frequency of rs9364559 minor allele (G) in case group was obviously higher than that in control group. Results of haplotype analysis showed that 4 haplotypes which contained rs9364559-G were associated with increased risk of CAD in this population. This study explored rs9364559 in theLPAgene may be associated with the pathogenesis of CAD; and the risk of CAD might be higher in the population carrying 4 haplotypes of different blocks in theLPAgene.

Objectives. To evaluate whether serum interleukin-6 (IL-6) is associated with increased risk of mortality in coronary artery disease (CAD) patients.Methods. We performed a prospective cohort study of 718 CAD patients from the Guangzhou Cardiovascular Disease Cohort (GCDC) study. Multivariable-adjusted Cox proportional hazards regression analyses were used to examine the association between serum IL-6 with all-cause and cardiovascular mortality.Results. During the 1663 person-years of followup, the cumulative all-cause mortality and cardiovascular mortality were 6.5% (n=47) and 3.3% (n=24), respectively. The mean length of followup was2.32±0.81years. In the multivariable analyses, a one-SD increment in log-transformed serum IL-6 was positively associated with an increased risk of all-cause and cardiovascular mortality, with hazard ratios (HR) of 2.93 (95% CI, 2.11–4.08) and 2.04 (95% CI, 1.34–3.68) within the patients combined and 2.98 (95% CI, 2.12–4.18) and 3.10 (95% CI, 1.98–4.85) within males, respectively. Patients in the highest serum IL-6 tertile versus the lowest tertile were at higher risk of all-cause and cardiovascular mortality, with HR of 17.12 (95% CI 3.11–71.76) and 8.68 (95% CI, 1.88–37.51), respectively.Conclusions. In hospitalized patients with CAD, serum IL-6 is significantly associated with all-cause and cardiovascular mortality.
