Analysis of polymorphisms Leiden Factor V G1691A and prothrombin G20210A as risk factors for acute myocardial infarction.

2011

Thrombotic risk increases in elderly, therefore, the understanding of the genetic predisposition of hypercoagulability could make the difference in the prevention of venous and/or arterial thrombotic events. Laboratory evaluation of hyperfibrinogenemia, increased Factor VII levels, antiphospholipid antibodies presence and hyperhomocysteinemia are considered to have a consistent high predictivity for arterial thrombophilic diseases. Anyway, a large debate exists on the validity of testing Leiden Factor V (FV) G1691A and/or prothrombin (FII) G20210A polymorphisms in patients affected by arterial thrombotic diseases, despite of the several observations described. Here we report data strongly s…

Association between HFE mutations and acute myocardial infarction: a study in patients from Northern and Southern Italy.

2003

There is interest in the role of iron in age-related diseases such as atherosclerosis. Tissue iron deposition could be harmful, because Fe(2+) can react with H(2)O(2) to form OH(-) radicals and Fe(2+) can react with O(2) to form reactive oxygen species. Free radicals react with cell membranes and cell organelles and could lead to the development of atherosclerosis by initiating lipid peroxidation. Hereditary hemochromatosis provides an opportunity for studying the effects of iron on cardiovascular disease. Some studies have shown that individuals who carried HFE mutations may be at greater risk of developing coronary heart disease than those without the mutations. In contrast, a large numbe…

Opposite effects of interleukin 10 common gene polymorphisms in cardiovascular diseases and in successful ageing: genetic background of male centenar…

2004

Many aspects of ageing involve inflammatory processes. We evaluated the association with longevity of alleles of IL10 and TNFa, known to have opposite functions in inflammatory reactions, IL-10 acting predominantly as an anti-inflammatory and TNF-a as a proinflammatory factor. The number of male centenarians homozygous for the –1082G genotype, suggested to be associated with high IL-10 production, was significantly increased in comparison with younger control subjects. No significant differences were observed between women and controls. The genotypic frequencies of the TNFa promoter SNPs 308G and 308A, suggested to be associated with low and high TNF-a production respectively, were not sign…

Interleukin-6 gene polymorphism is an age-dependent risk factor for myocardial infarction in men.

2005

Summary Several studies show that inflammatory components may contribute to atherosclerosis and increase the risk for myocardial infarction (MI). Interleukin-6 (IL-6) is a key pro-inflammatory and immune-modulatory cytokine of relevance for cardiovascular diseases. In this case-control study, 200 patients with MI and 257 healthy controls were genotyped for the polymorphism present in −174 promoter region of the IL-6 gene. Plasma concentrations of IL-6 and C-reactive protein (CRP) in a group of patients and controls were measured. The −174 C allele was associated with an increased risk of developing MI (OR = 2.886, c.i. = 1.801–4.624, P = 0.0001) in older patients, while no association was f…
