Interleukin-6 serum levels and genotypes influence the risk for myocardial infarction

Bennet, A·2003·Atherosclerosis

Abstract

Objective Several studies show that the inflammatory component in atherosclerosis may contribute to increased risk for cardiovascular disease (CVD). Interleukin-6 (IL-6) is a key pro-inflammatory and immune-stimulatory cytokine of presumed importance for CVD and the metabolic syndrome.Methods and results In this case-control study, 1179 surviving myocardial infarction (MI) cases and 1528 healthy controls were genotyped for three IL-6 promoter SNPs, and serum concentrations of IL-6 and C-reactive protein (CRP) were measured. In men, MI risk assessed as odds ratios (OR) was higher with increasing IL-6 levels, with the highest compared to the lowest IL-6 quartiles giving an OR of 2.7 [95% CI 1.7-4.4]. The ORs were independent from the effects of elevated CRP which were associated with modest MI risks (OR = 1.6 [95% CI 1.0-2.5]). Also, synergistic interactions between high IL-6 levels and hypercholesterolaemia further increased MI risk estimates. The -174C allele was associated with lower serum-insulin levels among male controls but did not significantly influence MI risk or IL-6 levels.Conclusions Elevated IL-6 levels are important risk markers for MI in men, the risk being further enhanced through synergistic interaction with hypercholesterolaemia. The data provide no clear evidence that polymorphisms in the IL-6 promotor region play a significant role in the pathogenesis of MI, and it remains to be further evaluated whether or not the -174C allele is of relevance for insulin resistance.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
