The homozygous deletion allele of the angiotensin-converting enzyme gene (ACE/DD), homozygous threonine allele of the angiotensinogen gene (AGN/TT), and the epsilon4 allele of the apolipoprotein E gene (apoE/epsilon4) are reported to be associated with ischemic heart disease.
Genotypes for the M235T and T174Mangiotensinogen mutations were compared between controls and Copenhagen City Heart Study participants with ischemic heart disease, myocardial infarction, and cerebrovascular disease (studies 1a, 1b, and 1c) and patients from Copenhagen University Hospital with the same conditions (studies 2a, 2b, and 2c).
The possible role of functional polymorphisms in the promoter regions of the IL-6, IL-10 and TGF-beta1 genes in the susceptibility to ischaemic heart disease (IHD) was investigated in a well-defined Irish population using two recently described family-based tests of association.
When available studies were pooled into the meta-analysis, there was no significant association between IL-6 polymorphisms (-174G/C, -572G/C) and IHD/IS in any comparison model (CC vs GG, GC vs GG, dominant, and recessive models).
No significant associations between clinical IHD manifestations and polymorphisms for SERCA, Kir6.1, and Kv1.5 were observed (p > 0.05), whereas specific polymorphisms detected in eNOS, as well as in Kir6.2 and Nav1.5 were found to be correlated with IHD and microvascular dysfunction.
Several groups have investigated the role of the G894T polymorphism of the eNOS gene in IHD by using case-control association studies; however, its role is unclear because of contradictory results from these studies.
The principal prior hypothesis was that homozygosity for eNOS Asp298, the -786C allele in the promoter, or the intron-4 (a allele) would be associated with an increased risk of IHD.
The results indicated that female sex, diabetes, and mutation in -786T/CeNOS gene correlate with ACh-provoked myocardial ischemia in patients with coronary spasm.
We analysed the association of the Glu298Asp polymorphism of the endothelial nitric oxide synthase (eNOS) gene with ischemic heart disease (IHD) and albuminuria in 337 Japanese diabetes patients.
JAK2V617F somatic mutation positives versus negatives had higher erythrocyte (P = 2 × 10(-5) ), thrombocyte (P = 2 × 10(-16) ), and leucocyte (P = 4 × 10(-9) ) counts, and had 2·7-/2·5-fold risk of cancer (prevalent/incident), 44-/28-fold risk of haematological cancer, 221-/97-fold risk of myeloproliferative cancer, 2·2-/1·2-fold risk of ischaemic heart disease, and 3·1-/1·0-fold risk of venous thromboembolism.
Tissue factor +5466A>G polymorphism determines thrombin formation following vascular injury and thrombin-lowering effects of simvastatin in patients with ischemic heart disease.
The aim of this study was to evaluate the CXCL10, CCL20 and CCL22 levels and the single nucleotide polymorphisms (SNPs) rs4508917, rs6749704 and rs4359426 in chemokine genes in patients with IHD to clarify any association.
The impact of OGG1, MTH1 and MnSOD gene polymorphisms on 8-hydroxy-2'-deoxyguanosine and cellular superoxide dismutase activity in myocardial ischemia-reperfusion.
For example, an increment in the two-day average (lag1-2) level of PM<sub>2.5</sub> by one IQR (34.4 µg/m<sup>3</sup>) was associated with a 6.3% (95%CI: 3.0%-9.8%) increase in the daily count of admissions for ischemic heart disease in Hanoi and with 23.2% (95%CI: 11.1%-36.5%) for cardiac failure in Quang Ninh.
We genotyped participants from the Copenhagen City Heart Study (n=10 352), the Copenhagen General Population Study (n=26 042), the Copenhagen Carotid Stroke Study (n=398 cases+796 control subjects), and the Copenhagen Ischemic Heart Disease Study (n=4901 cases+9798 control subjects) for the R103C, R287Q, and Arg(402-403ins) variants in the EPHX2 gene and recorded hospital admissions due to ischemic stroke, myocardial infarction, and ischemic heart disease.
The presence of -588T allele in GCLM and -129T allele in GCLC gene genotypes was associated with an increased risk of IHD (GCLM -588T: OR = 3.92, <i>p</i> = 0.003; GCLC -129T: OR = 3.22, <i>p</i> = 0.03) for general ethnically mixed group.
