Association of plasma pentraxin-3 levels with coronary risk factors and the lipid profile: a cross-sectional study in Japanese patients with stable angina pectoris.

Abstract

The aim of this study was to evaluate the relationships among the traditional risk factors, lipid profile, and pentraxin-3 in stable angina (SAP). Plasma pentraxin-3 and serum LDL, HDL, and high-sensitivity CRP levels were measured in 163 SAP and 28 non-coronary artery disease (CAD) patients. Their relationships with five risk factors, hypertension (HT), dyslipidemia (DL), diabetes mellitus (DM), obesity (body mass index: BMI > 25kg/m2), and high age (> 75years), were evaluated. No significant difference was observed in the pentraxin-3 level between patients in SAP and in non-CAD [2.1 (1.4-3.5) ng/ml versus off 2.6 (1.6-3.8) ng/ml, P = 0.56). In SAP patients, pentraxin-3 levels decreased with more risk factors, according to the number of 3 traditional risk factors (HT, DL, and DM) and the number of 5 expanded risk factors (HT, DL, DM, obesity, and high age) (P for trend = 0.01 and 0.05, respectively). Pentraxin-3 showed a positive association with HDL (rs = 0.229; P = 0.050) and an inverse association with LDL (rs = - 0.224; P = 0.045). On multiple logistic regression, the number of 3 traditional risk factors was a significant predictor of pentraxin-3 levels (odds ratio = 0.444; 95% confidence interval 0.205-0.963, P = 0.040) in SAP patients. In SAP patients, the cardiovascular risk factor burden remained a negative impact on pentraxin-3 levels after multivariate analysis, suggesting that they have distinct roles in atherosclerosis.Trial registration: UMIN000023837.
