We genotyped 45 CAD-associated SNPs in 701 stable CAD patients in whom levels of high-sensitivity C-reactive protein (hsRCP), interleukin-6, calprotectin, fibrinogen and complement component 3 levels had previously been measured.
Serum concentrations of MCP-1 and IL-6 in combination predict the presence of coronary artery disease and mortality in subjects undergoing coronary angiography.
In this Review, we describe some of these challenges in interpreting MR analyses, including those from studies using genetic variants to assess causality of multiple traits (such as branched-chain amino acids and risk of diabetes mellitus); studies describing pleiotropic variants (for example, C-reactive protein and its contribution to coronary heart disease); and those investigating variants that disrupt normal function of an exposure (for example, HDL cholesterol or IL-6 and coronary heart disease).
Inflammatory markers tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), C-reactive protein (CRP), and the soluble forms of intracellular adhesion molecule (sICAM-1) and vascular CAM-1 (sVCAM-1) are associated with increased risk of diabetes and coronary heart disease.
Previous experiments have demonstrated that several inflammatory biomarkers, including pentraxin 3 (PTX3), matrix metalloprotein 9 (MMP9), interleukin-6 (IL-6), and the neutrophil to lymphocyte ratio (NLR), are differentially elevated in coronary artery disease (CAD).
IL-6, an upstream inflammatory marker, was independently associated with the risk of major adverse cardiovascular events, cardiovascular and all-cause mortality, myocardial infarction, heart failure, and cancer mortality in patients with stable coronary heart disease.
Furthermore, changes in LDL cholesterol (β=-0.158, P=0.027) and interleukin-6 (β=-0.154, P=0.044) remained independent determinants of omentin-1 alterations in standard multiple regression analysis (R=0.122, P=0.006) after adjusting for age, sex, smoking, family history of CAD, and BMI in patients with CAD.
Expanded CD8(+)IL-6Rα(low) T cells positively correlated with the frequency of senescent, cytotoxic CD8(+)CD57(+) T cells (r = 0.6655, p < 0.0001) and plasma IL-6 level (r = 0.3995, p = 0.0432) in CAD patients.
The interleukin 6 c.-174 CC genotype is a predictor for new cardiovascular events in patients with coronary heart disease within three years follow-up.
Presence of metabolic syndrome (MS) and its components, presence of heart failure, severity of CAD symptoms, severe past ventricular arrhythmia (sustained ventricular tachycardia [sVT] or ventricular fibrillation [VF]), lower left ventricle ejection fraction, higher left ventricle mass index, higher end-diastolic volume and higher number of smoking pack-years were significantly associated with higher WBC, CRP and IL-6.
Our study suggests that the IL-6-174G/C (rs1800795) and IL-10 -1082A/G (rs1800896) polymorphisms might be involved in the pathogenesis of CAD, and likely contribute to the genetic susceptibility for CAD.
CC genotype and C allele in rs614230 (CX3CL1) were significantly related with decreased risk of CAD (OR=0.38, 95% CI=0.17-0.86; OR=0.66, 95% CI=0.45-0.97).For IL-6rs2066992 polymorphism.
The aim of this study was to investigate the association between NFKB1 and NFKBIA polymorphisms and the susceptibility to CAD and their impact on plasma levels of IL-6 in a Chinese Uygur population.
