Abstract

Aims: The strength of the relationship of triglyceride-rich lipoproteins (TRL) with risk of coronary heart disease (CHD) compared with low-density lipoprotein (LDL) is yet to be resolved. Methods and results: Single-nucleotide polymorphisms (SNPs) associated with TRL/remnant cholesterol (TRL/remnant-C) and LDL cholesterol (LDL-C) were identified in the UK Biobank population. In a multivariable Mendelian randomization analysis, TRL/remnant-C was strongly and independently associated with CHD in a model adjusted for apolipoprotein B (apoB). Likewise, in a multivariable model, TRL/remnant-C and LDL-C also exhibited independent associations with CHD with odds ratios per 1 mmol/L higher cholesterol of 2.59 [95% confidence interval (CI): 1.99–3.36] and 1.37 [95% CI: 1.27–1.48], respectively. To examine the per-particle atherogenicity of TRL/remnants and LDL, SNPs were categorized into two clusters with differing effects on TRL/remnant-C and LDL-C. Cluster 1 contained SNPs in genes related to receptor-mediated lipoprotein removal that affected LDL-C more than TRL/remnant-C, whereas cluster 2 contained SNPs in genes related to lipolysis that had a much greater effect on TRL/remnant-C. The CHD odds ratio per standard deviation (Sd) higher apoB for cluster 2 (with the higher TRL/remnant to LDL ratio) was 1.76 (95% CI: 1.58–1.96), which was significantly greater than the CHD odds ratio per Sd higher apoB in cluster 1 [1.33 (95% CI: 1.26–1.40)]. A concordant result was obtained by using polygenic scores for each cluster to relate apoB to CHD risk. Conclusion: Distinct SNP clusters appear to impact differentially on remnant particles and LDL. Our findings are consistent with TRL/remnants having a substantially greater atherogenicity per particle than LDL.

  • Moderate elevations in triglyceride levels are associated with an increased risk of atherosclerotic cardiovascular disease.

    “Moderate elevations in triglyceride levels are associated with an increased risk of atherosclerotic cardiovascular disease, 1,2,19,20”

    From Targeting <i>APOC3</i> with Olezarsen in Moderate Hypertriglyceridemia (2025) · cites this paper as [19]

    The Results (page not specified) report that triglycerides were a significant predictor of ASCVD in Mendelian-randomisation models, supporting the general association. The paper does not establish the claim specifically for moderate elevations; its observational triglyceride-to-LDL-C association also became non-significant after adjustment for HDL-C. (LLM, conf=0.84)

  • When lipid metabolism is imbalanced, elevated levels of RC can lead to its infiltration into the arterial wall, causing cholesterol deposition beneath the endothelium and accelerating the formation of foam cells and lipid plaques, while provoking a low-grade inflammatory response, significantly increasing the risk of AS.

    “In summary, when lipid metabolism is imbalanced, elevated levels of RC can lead to its infiltration into the arterial wall, causing cholesterol deposition beneath the endothelium and accelerating the formation of foam cells and lipid plaques, while provoking a low-grade inflammatory response. These processes significantly increase the risk of AS.”

  • Mendelian randomization analyses confirm a causal relationship between lifelong TRL elevation and ASCVD.

    “Observational cohorts demonstrate that higher TG and remnant cholesterol predict cardiovascular events independently of LDL-C, while Mendelian randomization analyses confirm a causal relationship between lifelong TRL elevation and ASCVD.”

    From Targeting triglycerides for cardiovascular risk reduction (2026) · cites this paper as [56]

    The Results report that genetically defined increases in TRL/remnant cholesterol predict ASCVD outcomes in multivariable Mendelian randomisation models. However, the Introduction describes the association as “likely causal,” not confirmed, and the cited passages do not establish that TRL elevation was lifelong. Page numbers are unavailable in our copy. (LLM, conf=0.85)

  • RC may have a stronger atherogenic effect than LDL-C.

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.
