Abstract

BACKGROUND: Nuclear magnetic resonance (NMR) spectroscopy measures the number and size of lipoprotein particles instead of their cholesterol or triglyceride content, but its clinical utility is uncertain. METHODS AND RESULTS: Baseline lipoproteins were measured by NMR in 27 673 initially healthy women followed up for incident cardiovascular disease (n=1015) over an 11-year period. After adjustment for nonlipid risk factors, hazard ratios and 95% confidence intervals for the top versus the bottom quintile of NMR-measured lipoprotein particle concentration (measured in particles per liter) were 2.51 (1.91 to 3.30) for low-density lipoprotein (LDL(NMR)), 0.91 (0.75 to 1.12) for high-density lipoprotein (HDL(NMR)), 1.71 (1.38 to 2.12) for very low-density lipoprotein (VLDL(NMR)), and 2.25 (1.80 to 2.81) for the LDL(NMR)/HDL(NMR) ratio. Similarly adjusted results for NMR-measured lipoprotein particle size (measured in nanometers) were 0.64 (0.52 to 0.79) for LDL(NMR) size, 0.65 (0.51 to 0.81) for HDL(NMR) size, and 1.37 (1.10 to 1.70) for VLDL(NMR) size. Hazard ratios for NMR measures were comparable but not superior to standard lipids (total cholesterol 2.08 [1.63 to 2.67], LDL cholesterol 1.74 [1.40 to 2.16], HDL cholesterol 0.52 [0.42 to 0.64], triglycerides 2.58 [1.95 to 3.41], non-HDL cholesterol 2.52 [1.95 to 3.25], total/HDL cholesterol ratio 2.82 [2.23 to 3.58]) and apolipoproteins (B(100) 2.57 [1.98 to 3.33], A-1 0.63 [0.52 to 0.77], and B(100)/A-1 ratio 2.79 [2.21 to 3.54]). Essentially no reclassification improvement was found with the addition of the LDL(NMR) particle concentration or apolipoprotein B(100) to a model that already included the total/HDL cholesterol ratio and nonlipid risk factors (net reclassification index 0% and 1.9%, respectively), nor did the addition of either variable result in a statistically significant improvement in the c-index. CONCLUSIONS: In this prospective study of healthy women, cardiovascular disease risk prediction associated with lipoprotein profiles evaluated by NMR was comparable but not superior to that of standard lipids or apolipoproteins.

  • 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).”

    From Evaluation and Treatment of Hypertriglyceridemia: An Endocrine Society Clinical Practice Guideline (2012) · cites this paper as [38]

    The Results (Association of NMR Lipoproteins, Lipids, and Apolipoproteins with CVD; page unavailable) report that large LDL particles were significantly associated with incident cardiovascular disease in women when all nine particle subclasses were included in the model. They were not associated with cardiovascular disease in the separate adjusted model. The paper does not establish that large LDL specifically predicts atherosclerosis or coronary heart disease. (LLM, conf=0.87)

    Experimental — accuracy not yet measured
  • Prior studies have shown that nuclear magnetic resonance spectroscopy is not superior to conventional lipid profiles.

    “While such an approach can specifically measure the number and particle size of lipoprotein particles, prior studies have shown that they are not superior to conventional lipid profiles.22”

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.
