Systemic Inflammatory Markers Are Closely Associated with Atherogenic Lipoprotein Subfractions in Patients Undergoing Coronary Angiography

چکیده
OBJECTIVE To investigate the relationship between inflammatory markers and atherogenic lipoprotein subfractions. METHODS We studied 520 eligible subjects who were not receiving any lipid-lowering therapy. The inflammatory markers including white blood cell (WBC) count, high-sensitivity C-reactive protein (hs-CRP), fibrinogen, erythrocyte sedimentation rate (ESR), and D-dimer were measured. A multimarker inflammatory index was developed. Low-density lipoprotein (LDL) and high-density lipoprotein (HDL) separation processes were performed using Lipoprint System. RESULTS In age- and sex-adjusted analysis, several inflammatory markers (WBC count, hs-CRP, fibrinogen, and ESR) were positively related to circulating non-HDL cholesterol and remnant cholesterol (p < 0.05, all). Among lipoprotein subfractions, we observed a positive association of inflammatory markers with very low-density lipoprotein cholesterol, small LDL cholesterol, and LDL score (p < 0.05, all). Meanwhile, a negative association was detected between inflammatory markers and mean LDL particle size (p < 0.05) or large HDL cholesterol (p < 0.05). Moreover, we found that the relationships between multimarker index quartiles and small LDL cholesterol, LDL score, and mean LDL particle size were slightly stronger in patients with CAD. CONCLUSIONS Systemic inflammatory markers are positively correlated with small LDL cholesterol and LDL score while being negatively linked with mean LDL particle size and large HDL cholesterol, highlighting the potential contribution to increased cardiovascular risk.

OBJECTIVES (a) To characterise the lipid profile in psoriatic arthritis and investigate whether there are similarities to the dyslipoproteinaemia reported in rheumatoid arthritis and other inflammatory forms of joint disease; (b) to investigate whether there is an atherogenic lipid profile in psoriatic arthritis, which may have a bearing on mortality. METHODS Fasting lipids, lipoproteins, and...
متن کاملThe effects of Vitamin C on Inflammatory Markers and Atrial Fibrillation in Patients Undergoing Coronary Artery Bypass Surgery in Bushehr Heart Center: A Randomized Controlled Clinical Trial
Background: Coronary artery bypass graft surgery (CABG) with cardiopulmonary bypass pump may cause systemic inflammatory reactions by releasing cytokines which leads to multiple organ failure. Vitamin C has anti-inflammatory and antioxidant properties. The study aimed to determine the effect of vitamin C on inflammatory markers and atrial fibrillation in patients undergoing CABG. Materials and ...
متن کاملParaoxonase 1 Activity, Lipid Profile, and Atherogenic Indexes Status in Coronary Heart Disease
Background: Dyslipidemia is considered an independent risk factor for coronary heart disease (CHD). In the present study, we examined lipid profiles and paraoxonase 1 (PON1) activity and atherogenic indexes status and the relationship of PON1 activity by high-density lipoprotein (HDL) and atherogenic indexes in CHD patients and healthy people. Methods: The aim of the study was to compare PON...
متن کاملThe association between small dense low density lipoprotein,apolipoprotein B, apolipoprotein B/apolipoprotein A1 ratio and coronary artery stenosis
Abstract Background: Recently, small dense low density lipoprotein (sdLDL) has been highlighted as a new risk factor for the coronary artery disease (CAD).Small dense LDLs are believed to be atherogenic since these particles are taken up more easily by arterial wall. They are readily oxidized and have reduced affinity for low density lipoprotein (LDL) receptor and increased affinity...

The major Lipoprotein classes are heterogenous. Human serum High-Density-Lipoproteins (HDL) are separated into two major subfractions (HDL2, d=1.063-1.125 g/ml, HDL3, d=1.125-1.210 g/ml) by a simple double precipitation method. There was a strong inverse relation between HDL-Cholesterol (HDL-C) and subfractions HDL2-C and HDL3-C with atherosclerosis. This study demonstrated that HDL-C (P<0.001)...
