Low-Density Lipoprotein Size and Cardiovascular Disease: A Reappraisal

Sacks, Frank M., Campos, Hannia·2003·The Journal of Clinical Endocrinology & Metabolism

Abstract

The major lipoprotein types, very low-density lipoprotein (VLDL), low-density lipoprotein (LDL), and high-density lipoprotein (HDL), are composed of many subgroups (1–3). Classifications are based on size (1), density, or apolipoprotein (apo) content (2), or a combination of these (3), and the subfractions that are isolated have distinct metabolic and other functional properties. Thus, it is entirely reasonable to think that subfractions of the major lipoproteins have diverse relationships to coronary heart disease (CHD). Because the classical lipid risk factors by no means perfectly predict CHD in patients, lipoprotein subfractionation has the potential to improve risk prediction. Among the various lipoprotein subfractionation systems, LDL size and density by far have attracted the most basic, clinical, and population research. Several companies offer LDL size measurements to physicians as a diagnostic test for CHD risk. Several lines of evidence implicate small, dense LDL in the etiology of CHD. Small, dense LDL is often increased in relative proportion or concentration in patients with CHD. Small, dense LDL has several characteristics that are linked to atherogenesis: long residence time in plasma, and enhanced oxidizability, arterial proteoglycan binding, and permeability through the endothelial barrier (4). Together, these findings have led to the hypothesis that small, dense LDL is a potent atherogenic lipoprotein that can be used to improve risk prediction, and evaluate response to lipid therapy (5–7). Furthermore, small, dense LDL is often part of a group of high-risk characteristics including high triglycerides, low HDL, diabetes, insulin resistance, obesity, and the metabolic syndrome (8–10). This has led logically to the concept that it contributes to the high rate of CHD in these groups. Yet, the very association between small, dense LDL and these other high-risk conditions challenges proponents of the hypothesis to show a direct, independent relationship between small, dense LDL and CHD. In this article, we evaluate evidence on LDL subclasses in risk assessment and therapy, reaching the conclusion that LDL subclass measurement does not add independent information to that conferred generically by the LDL concentration along with the other standard risk factors.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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

  • Neither LDL size nor the concentration of small, dense LDL particles adds to CVD prediction in multiple variable analysis beyond standard lipid risk factors, although small LDL particles predict cardiovascular risk in univariate analysis.

    “Neither LDL size nor the concentration of small, dense LDL particles adds to CVD prediction in multiple variable analysis beyond the standard lipid risk factors, although small LDL particles predict cardiovascular risk in univariate analysis (35)(36)(37).”
  • Prospective multivariate studies demonstrate that large LDL predicts atherosclerosis and coronary heart disease.

    “Prospective multivariate studies demonstrate that large LDL predicts atherosclerosis and coronary heart disease (35,38,39).”

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.
