The observation that premenopausal women have a relatively low incidence of heart disease led in the nineteen eighties to the hypothesis that iron deficiency protects against heart diseases. These early observations were followed-up by conflicting epidemiological data. To confer causal relationships from epidemiological data is challenging as results can be influenced by residual confounding or reverse causation. For bias reduction, an alternative analysis strategy utilizing single-nucleotide polymorphisms (SNPs) as instrumental variables (Mendelian Randomization) has been developed...

Characterizing the relationship between genetic, epigenetic (e.g., deoxyribonucleic acid [DNA] methylation), and transcript variation could provide insights into mechanisms regulating hemostasis and potentially identify new drug targets. Several hemostatic factors are synthesized in the liver, yet high-resolution DNA methylation data from human liver tissue is currently lacking for these genes. Single-nucleotide polymorphisms (SNPs) can influence DNA methylation in cis which can affect gene expression. This can be analyzed through allele-specific methylation (ASM) experiments...

BACKGROUND: Previous genome-wide association studies have found two single nucleotide polymorphisms (SNP) rs7692387 and rs1842896 located on or near the GUCY1A3 gene were associated with coronary artery disease (CAD). GUCY1A3 was considered to be involved in the process of atherosclerosis, but there was little information about the association between genotypic polymorphisms of the GUCY1A3 and large artery atherosclerotic (LAA) stroke. This study aimed to investigate the associations between the GUCY1A3 rs7692387, rs1842896 polymorphisms and LAA stroke susceptibility...

BACKGROUND: Although many observational studies have shown an association between plasma homocysteine levels and cardiovascular diseases, controversy remains. In this study, we estimated the role of increased plasma homocysteine levels on the etiology of coronary heart disease and acute myocardial infarction. METHODS: A two-sample Mendelian randomization study on disease was conducted, i.e. "coronary heart disease" ( n  = 184,305) and "acute myocardial infarction" ( n  = 181,875)...

Whether circulating fatty acids (FAs) play a causal role in the development of cardiovascular disease (CVD) remains unclear. We conducted a Mendelian randomisation study to explore the associations between plasma phospholipid FA levels and 15 CVDs. Summary-level data from the CARDIoGRAMplusC4D, MEGASTROKE, and Atrial Fibrillation consortia and UK Biobank were used. Sixteen single-nucleotide polymorphisms (SNPs) associated with ten plasma FAs were used as instrumental variables. SNPs in or close to the FADS1 gene were associated with most FAs...

Background: Acute myocardial infarction (AMI) which is a specific type of coronary artery disease (CAD), is caused by the combination of genetic factors and acquired environment. Although some common genetic variations have been recorded to contribute to the development of CAD and AMI, more genetic factors and potential molecular mechanisms remain largely unknown. The GATA6 gene is expressed in the heart during embryogenesis and is also detected in vascular smooth muscle cells (VSMCs), different human primary endothelial cells (ECs), and vascular ECs in mice...

OBJECTIVE: Coronary artery disease contributes to noncommunicable disease deaths worldwide. In order to make preventive methods more accurate, we need to know more about the development and progress of this pathology, including the genetic aspects. Humanin is a small peptide known for its cytoprotective and anti-apoptotic properties. Our study looked for genomic associations between humanin-like nuclear isoform genes and coronary artery disease using CARDIoGRAMplusC4D Consortium data...

Background Sudden cardiac death (SCD) accounts for ≈300 000 deaths annually in the United States. Men have a higher risk of SCD and are more likely to have underlying coronary artery disease, while women are more likely to have arrhythmic events in the setting of inherited or acquired QT prolongation. Moreover, there is evidence of sex differences in the genetics of QT interval duration. Using sex- and coronary artery disease-stratified analyses, we assess differences in genetic association between longer QT interval and SCD risk...

BACKGROUND: Coronary artery disease (CAD) including acute myocardial infarction (AMI) is a common complex disease caused by atherosclerosis. Vascular epithelial growth factor receptor-1 (VEGFR-1) stimulates angiogenesis and vascular permeability, and functions as a decoy to sequester VEGF and prevent initiation of intracellular signaling. VEGFR-1 knockout mice exhibit significantly higher mortality due to heart failure, cardiac hypertrophy, and cardiac dysfunction. An evident increase in macrophage infiltration and cardiac fibrosis are also observed after transverse aortic constriction...

Vascular endothelial growth factor C (VEGF-C) promotes angiogenesis, a prominent feature in rheumatoid synovitis, contributing to the perpetuation of the global burden of rheumatoid arthritis (RA). VEGF-C gene polymorphisms predict the risk of developing various human diseases, such as urothelial cell carcinoma, oral cancer and coronary artery disease. We sought to determine whether single nucleotide polymorphisms (SNPs) of the VEGF-C gene can predict the risk of RA. Our study recruited 210 patients with RA and 373 healthy controls between 2007 and 2015, and performed comparative genotyping for SNPs rs7664413, rs11947611, rs1485766, rs2046463 and rs3775194...

Coronary artery disease (CAD), a common cardiovascular disease, has become a vital cause of mortality worldwide. Genetic microRNA ( miR ) polymorphisms might contribute to CAD susceptibility. In this study, we selected miR-146a , miR-196a2 , and miR-499 single nucleotide polymorphisms and conducted a case-control study. In total, 505 CAD cases and 1109 controls were recruited. We used SNPscan™ genotyping assay to obtain genotyping of miR rs2910164, rs11614913, and rs3746444 variants. We found that miR-196a2 rs11614913 T > C decreased the susceptibility of myocardial infarction (MI) (TC vs...

Lead is pervasive, although lead exposure has fallen in response to public health efforts. Observationally, lead is positively associated with cardiovascular disease and hypertension. We used separate-sample instrumental variable analysis with genetic instruments (Mendelian randomization) based on 13 single nucleotide polymorphisms (SNP), from a genome wide association study, strongly (p-value < 5 × 10-6 ) and independently associated with blood lead. These SNPs were applied to a large extensively genotyped coronary artery disease (CAD) study (cases = <76014, controls = <264785) largely based on CARDIoGRAPMplusC4D 1000 Genomes and the UK Biobank SOFT CAD, to the UK Biobank (n = 361,194) for blood pressure and to the DIAGRAM 1000 genomes diabetes case (n = 26,676)-control (n = 132,532) study...

Coronary artery disease (CAD) and ischemic stroke (IS) are commonly considered distinct disease phenotypes. However, there is some evidence in favor of a degree of overlap between genetic susceptibility to CAD and genetic risk factors for IS. In the present study, we aimed to examine the role of two single-nucleotide polymorphisms (SNPs), rs3825807 and rs11556924, located in the ADAMTS7 and ZC3HC1 genes, respectively, associated with CAD in published GWASs in European populations and their possible contribution to the development of coronary atherosclerosis and cerebral LA atherosclerosis in a case-control study of an the Iranian population...

BACKGROUND: Previous studies have established that coronary artery disease is associated with excess inflammation. These studies have shown an elevation of both pro and anti-inflammatory cytokines in sufferers of coronary artery disease. There is increasing interest in the role played by the inflammasome Nod Like Receptor family pyrin domain containing 3 (NLRP3) in the aetiology of coronary artery disease. Increased severity of coronary artery disease correlates with higher levels of expression of NLRP3...

AIMS: Genetic contribution to coronary artery disease (CAD) remains largely unillustrated. Although transcriptomic profiles have identified dozens of genes that are differentially expressed in normal and atherosclerotic vessels, whether those genes are genetically associated with CAD remains to be determined. Here, we combined genetic association studies, transcriptome profiles and in vitro and in vivo functional experiments to identify novel susceptibility genes for CAD. METHODS AND RESULTS: Through an integrative analysis of transcriptome profiles with genome-wide association studies for CAD, we obtained 18 candidate genes and selected one representative SNP for each gene for multi-centered validations...

Although a large body of literature reported that high intake of vitamin E played a possible role in reducing risk of cardiometabolic diseases, conflicting results were also found in some observational studies due to confounding factors. Hence, we used a Mendelian randomization study as an alternative way to examine the causality between circulating vitamin E and cardiometabolic diseases. Summary-level data were extracted from consortia and three single nucleotide polymorphisms were used as instrumental variables...

Polymorphic variants of the CYP7A1 gene can increase the risk of atherosclerosis-based coronary artery disease (CAD) and modify serum lipid markers. Method: We studied haplotype-tagging single nucleotide polymorphisms of CYP7A1 in the Caucasian population and if they are associated with CAD, its symptoms, and any of its risk factors. Results: We did not find the genetic variants of CYP7A1 to be associated with an increased risk of CAD. However, we did find that the common rs3808607 variant is associated with modified concentrations of serum total cholesterol and LDL...
