  • Descrição: Abstract Introduction Calcific aortic valve disease (CAVD) is one of the most common heart diseases worldwide, and its prevalence has increased in developed countries along with aging populations. Subclinical CAVD is characterized by aortic valve calcification (AVC) that may lead to aortic stenosis. AVC shares the same risk factors with atherosclerotic disease. Recently, nuclear magnetic resonance (NMR)-based lipoprotein particles, low-density and high-density lipoprotein particles (LDL-p, HDL-p) in particular, have emerged as novel markers of atherosclerotic disease. It has been unclear, however, whether NMR-based particles are associated with AVC. Purpose To examine cross-sectional association of NMR-based lipoprotein particles, standard lipids with AVC, and compare their strengths of association. Methods We studied a community-based random sample of Japanese men aged 40–79 years examined in 2006–08 in Japan. We excluded participants with history of myocardial infarction, stroke, aortic valve surgery, serum triglyceride concentration ≥400 mg/dl, estimated glomerular filtration rate (eGFR) <30 (ml/min/1.73m2), and use of lipid-lowering medication. We scored the degree of AVC according to Agatston's method, and defined prevalent AVC as the score >0. Lipoprotein particles were measured using NMR spectroscopy. In our main analysis, we obtained multivariable-adjusted odds ratios (ORs) and 95% confidence intervals (95% CI) of prevalent AVC in the top quartile (Q4) for each lipid index in reference to the lowest quartile (Q1). Adjusting covariates include age, smoking, drinking, systolic blood pressure, glycated hemoglobin, medications for hypertension and/or for diabetes, eGFR, C-reactive protein. For sensitivity analysis, we repeated similar analyses presenting ORs per 1 standard deviation (SD) higher NMR-lipoproteins particles or standard lipids. Results Of 874 participants we analyzed, 153 (17.5%) men had AVC. The average (SD) age was 63.3 (10.0) years. Those with AVC tended to be older, likely to have clustering of atherosclerotic risk factors. Multivariable-adjusted ORs of prevalent AVC for Q4 versus Q1 were significantly positive for LDL-p [OR, 2.21 (95% CI: 1.24, 3.95] and low-density lipoprotein cholesterol (LDL-c) [2.17 (1.24, 3.80)]. In contrast, neither HDL-p nor high-density lipoprotein cholesterol (HDL-c) was significantly associated with AVC. In sensitivity analyses, however, the corresponding ORs per 1SD higher lipids/lipoprotein particles were smaller in LDL-p [1.33 (1.09, 1.63)] than LDL-c [1.41 (1.15, 1.73)]. The association of HDL-p became significant [1.28 (1.02, 1.61)] (per 1SD decrement) in the sensitivity analysis. Conclusion The overall associations of AVC with NMR-based lipoprotein particles (i.e. LDL-p, HDL-p) are comparable to those of standard lipids. This finding is parallel to the association between atherosclerotic cardiovascular diseases with NMR-based lipoproteins.
