Background: Oxidized low-density lipoprotein (OxLDL) and remnant lipoprotein play a crucial role in the development of atherosclerosis. Recently, a novel method for measuring remnant cholesterol levels (remnant lipoproteins cholesterol homogenous assay: RemL-C) has been established. However, the correlation between OxLDL and remnant lipoprotein, including RemL-C, has not been fully investigated.
Methods: We enrolled 25 consecutive patients with documented coronary artery disease (CAD) and 20 controls. Remnant-like particle cholesterol (RLP-C) and RemL-C were used to determine the levels of remnant lipoprotein cholesterol. Serum levels of malondialdehyde-modified LDL (MDA-LDL) and OxLDL using a monoclonal antibody DLH3 (OxPC) were used to measure the concentration of circulating OxLDL.
Results: The CAD group had high levels of fasting glucose and glycosylated hemoglobin (HbA1c), and low levels of high-density lipoprotein cholesterol compared with the control group. Serum levels of total cholesterol or LDL cholesterol were not significantly different between the two groups. The levels of RemL-C (p = 0.035), MDA-LDL (p = 0.018), and MDA-LDL/LDL-C (p = 0.036) in the CAD group were significantly higher than those in the control group. The levels of RLP-C tended to be higher in the CAD group than those in the control group (p = 0.096). Positive correlations were demonstrated between remnant lipoprotein cholesterol and OxLDL (RLP-C and MDA-LDL/LDL-C, r = 0.45, p = 0.0024, RLP-C and OxPC, r = 0.51, p = 0.0005, RemL-C and MDA-LDL/LDL-C, r = 0.42, p = 0.0044, RemL-C and OxPC, r = 0.43, p = 0.0043). Similar trends were observed in non-diabetic subjects and in subjects without metabolic syndrome. Positive correlations were also observed between RLP-C and RemL-C (r = 0.94, p < 0.0001) and between MDA-LDL/LDL-C and OxPC (r = 0.40, p = 0.0074).
Conclusions: These results suggest that the association between high levels of remnant lipoprotein cholesterol and high OxLDL levels might be linked to atherogenesis in patients with CAD.

The effectiveness of bariatric surgery in reducing remnant cholesterol (RC) levels, particularly when obesity is accompanied by elevated glycated hemoglobin (HbA1c), is insufficiently investigated. In this study, we aimed to examine the impacts of two common bariatric procedures, Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG), as regards their effects on RC and HbA1c levels. Adult morbidly obese subjects were included and assigned to receive either RYGB or SG.

Background: Remnant cholesterol (remnant-C) contributes to atherosclerotic cardiovascular disease (ASCVD), particularly in individuals with impaired glucose metabolism. Patients with impaired glucose metabolism and ASCVD remain at significant residual risk after coronary artery bypass grafting (CABG). However, the role of remnant-C in this population has not yet been investigated.

Background/objectives: Hypertriglyceridaemia and systemic inflammation are prevalent in patients with schizophrenia and contribute to an increased risk of cardiovascular disease. Although elevated triglycerides (TGs) and remnant cholesterol are linked to inflammation in the general population and individuals with metabolic syndrome, whether they are associated in patients with schizophrenia remains unclear.
Methods: Fasting levels of TG, cholesterol (total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C) and remnant cholesterol)), and markers of systemic inflammation including high-sensitivity C-reactive protein (hsCRP), leukocyte counts and their differentials (neutrophils, monocytes and lymphocytes) were determined in 147 patients diagnosed with schizophrenia on long-term antipsychotic regimens and compared with 56 age- and sex-matched healthy controls.

Objective: There is no evidence to suggest that an association exists between the remnant cholesterol (RC) to high-density lipoprotein cholesterol (HDL-C) ratio and gestational diabetes mellitus (GDM). In this study, the RC/HDL-C ratio during the first trimester was examined as a potential indicator of the onset of GDM during the second trimester.
Methods: This was a secondary analysis of data from a Korea-based prospective cohort study.
