Abstract

IMPORTANCE: Lipid management typically focuses on levels of low-density lipoprotein cholesterol (LDL-C) and, to a lesser extent, triglycerides (TG). However, animal models and genetic studies suggest that the atherogenic particle subpopulations (LDL and very-low-density lipoprotein [VLDL]) are both important and that the number of particles is more predictive of cardiac events than their lipid content. OBJECTIVE: To determine whether common measures of cholesterol concentration, TG concentration, or their ratio are associated with cardiovascular risk beyond the number of apolipoprotein B (apoB)-containing lipoproteins. DESIGN, SETTING, AND PARTICIPANTS: This prospective cohort analysis included individuals from the population-based UK Biobank and from 2 large international clinical trials, FOURIER and IMPROVE-IT. The median (IQR) follow-up was 11.1 (10.4-11.8) years in UK Biobank and 2.5 (2.0-4.7) years in the clinical trials. Two populations were studied in this analysis: 389 529 individuals in the primary prevention group who were not taking lipid-lowering therapy and 40 430 patients with established atherosclerosis who were receiving statin treatment. EXPOSURES: ApoB, non-high-density lipoprotein cholesterol (HDL-C), LDL-C, and TG. MAIN OUTCOME AND MEASURES: The primary study outcome was incident myocardial infarction (MI). RESULTS: Of the 389 529 individuals in the primary prevention group, 224 097 (58%) were female, and the median (IQR) age was 56.0 (49.5-62.5) years. Of the 40 430 patients with established atherosclerosis, 9647 (24%) were female, and the median (IQR) age was 63 (56.2-69.0) years. In the primary prevention cohort, apoB, non-HDL-C, and TG each individually were associated with incident MI. However, when assessed together, only apoB was associated (adjusted hazard ratio [aHR] per 1 SD, 1.27; 95% CI, 1.15-1.40; P < .001). Similarly, only apoB was associated with MI in the secondary prevention cohort. Adjusting for apoB, there was no association between the ratio of TG to LDL-C (a surrogate for the ratio of TG-rich lipoproteins to LDL) and risk of MI, implying that for a given concentration of apoB-containing lipoproteins, the relative proportions of particle subpopulations may no longer be a predictor of risk. CONCLUSIONS AND RELEVANCE: In this cohort study, risk of MI was best captured by the number of apoB-containing lipoproteins, independent from lipid content (cholesterol or TG) or type of lipoprotein (LDL or TG-rich). This suggests that apoB may be the primary driver of atherosclerosis and that lowering the concentration of all apoB-containing lipoproteins should be the focus of therapeutic strategies.

TL;DR

In a large primary-prevention cohort and two secondary-prevention trial cohorts, apolipoprotein B (apoB) was the only lipid parameter independently associated with myocardial infarction after full adjustment. Neither lipid content nor lipoprotein type added risk beyond the number of apoB-containing particles.

Key findings

In 389,529 primary-prevention individuals not on lipid-lowering therapy, apoB, non–HDL-C, and TG were each individually associated with incident MI, but after full adjustment only apoB remained associated (aHR per 1 SD, 1.27; 95% CI, 1.15-1.40; P < .001).

  • In the same cohort, TG was associated with MI in clinically adjusted models (aHR per 1 SD, 1.16; 95% CI, 1.13-1.19; P < .001), but not after full clinical and lipid adjustment (aHR per 1 SD, 1.00; 95% CI, 0.96-1.04; P = .71).
  • In 40,430 patients with established atherosclerosis receiving statin treatment, only apoB was associated with MI; TG was not associated in clinically adjusted (aHR per 1 SD, 1.03; 95% CI, 0.99-1.07) or clinically and lipid-adjusted models (aHR per 1 SD, 0.94; 95% CI, 0.89-1.00).
  • Adjusting for apoB, the TG/LDL-C ratio was not associated with MI (aHR per 1 SD, 1.04; 95% CI, 0.99-1.09; P = .12), suggesting that for a given concentration of apoB-containing lipoproteins, particle type did not confer additional risk.

Methods

Prospective cohort analysis using UK Biobank primary-prevention individuals without lipid-lowering therapy (n = 389,529) and pooled secondary-prevention patients with established atherosclerosis from FOURIER and IMPROVE-IT receiving lipid-lowering therapy (n = 40,430). Median follow-up was 11.1 years in UK Biobank and 2.5 years in the clinical trials.

  • Exposures were apoB, non–HDL-C, LDL-C, and TG; the primary outcome was fatal or nonfatal MI.
  • Cox proportional hazards models estimated adjusted hazard ratios per 1 SD higher lipid parameter, with clinical adjustment and further adjustment for HDL-C, TG, non–HDL-C, and apoB; the TG/LDL-C ratio was evaluated with adjustment for apoB.

Limitations

The paper states that lipid values were measured using conventional lipid profiles rather than nuclear magnetic resonance spectroscopy, which would more accurately determine the VLDL-to-LDL ratio than the TG/LDL-C surrogate used.

  • The paper states that UK Biobank lipid values and lipid-lowering therapy data were collected at baseline and may have changed during follow-up; because individuals with higher lipid values would be most likely to start lipid-lowering therapy, this may have attenuated associations. The study was also not enriched for severe hypertriglyceridemia.
  • Evident from the text: the analysis is observational, limiting causal inference; the trial cohorts excluded patients with TG ≥400 mg/dL in FOURIER and ≥350 mg/dL in IMPROVE-IT, so severe hypertriglyceridemia is not represented.

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.
