Abstract

Background and aims Triglyceride-rich lipoproteins are causally associated with high risk of ischemic heart disease (IHD), and apolipoprotein E (apoE) has a central role in their plasma clearance. While both quantitative and qualitative changes of apoE are established causes of rare dyslipidemia syndromes, it remains unclear whether plasma levels of apoE are associated with risk of IHD in the general population. Methods We tested whether plasma levels of apoE at enrollment were associated with future risk of IHD and myocardial infarction (MI) in 91,695 individuals from the general population. Results Multifactorially adjusted hazard ratios (HRs) for highest versus lowest apoE tertile were 1.15 (1.04-1.27) for IHD and 1.16 (1.00-1.36) for MI in men, and 0.94 (0.84-1.05) and 1.04 (0.85-1.26) in women. These associations were attenuated by adjustments for triglyceride levels. Corresponding HRs for highest versus lowest apoE tertile in ε33 carriers were 1.18 (1.03-1.36) for IHD and 1.21 (0.98-1.49) for MI in men, and 0.91 (0.78-1.06) and 0.93 (0.71-1.21) in women. Thus, the present associations were independent of APOE genotype. Conclusion These findings suggest that high plasma levels of apoE are associated with IHD in men but not in women. Triglyceride-rich lipoproteins may partly explain these associations.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • In analyses stratified by APOE genotype and gender, LDL cholesterol, HDL cholesterol, triglycerides, apoA1 and apoB vary with plasma levels of apoE.

    “Furthermore, it has been shown, in analyses stratified by APOE genotype and gender, that LDL cholesterol, HDL cholesterol, triglycerides, apoA1 and apoB vary with plasma levels of apoE [116].”
  • In the cohort of about 91,000 participants, the association between high plasma apoE and risk of ischemic heart disease was not attenuated after adjustment for APOE genotype or stratification by ε33 genotype.

    “In this study, the epidemiological association between high plasma levels of apoE and risk of ischemic heart disease was not attenuated after adjustment for APOE genotype or after stratification by ε33 genotype, emphasizing a quantitative importance of apoE [116].”
  • High plasma levels of apoE seem to be associated with increased risk of ischemic heart disease, an association possibly mediated by triglyceride-rich lipoproteins.

    “Taken together, high plasma levels of apoE seems to be associated with increased risk of ischemic heart disease, an association possibly mediated by triglyceride-rich lipoproteins [116].”
  • Triglycerides most likely mediate the association between high plasma apoE and risk of ischemic heart disease.

    “reflecting that triglycerides most likely mediate these observations [116].”
  • In the cohort of about 91,000 participants, the associations between high plasma apoE and risk of ischemic heart disease were attenuated after adjustment for levels of triglycerides.

    “However, the associations were attenuated after adjustment for levels of triglycerides, reflecting that triglycerides most likely mediate these observations [116].”

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.
