Dyslipidemia is implicated as a risk factor for the development of atherosclerosis. Specifically triglyceride-rich lipoproteins and their lipolysis products are shown to be proinflammatory and proapoptosis in both in vivo and in vitro studies with endothelium. However, the role of triglyceride-rich lipoproteins in the progression of kidney diseases is not clear. Epidemiology studies demonstrated a correlation between renal disease and blood lipids. Recent evidence suggests that the mechanism may involve cellular uptake of lipid and de novo lipogenesis. Further studies are needed to establish the relevance of these mechanistic studies in human pathophysiology.

In health, the liver is a metabolically flexible organ that plays a key role in regulating systemic lipid and glucose concentrations. There is a constant flux of fatty acids (FAs) to the liver from multiple sources, including adipose tissue, dietary, endogenously synthesized from non-lipid precursors, intrahepatic lipid droplets and recycling of triglyceride-rich remnants. Within the liver, FAs are used for triglyceride synthesis, which can be oxidized, stored or secreted in very low-density lipoproteins into the systemic circulation.

Objective: Beyond glucose-lowering, sodium-glucose co-transporter 2 (SGLT2) inhibitors have cardioprotective effects with unclear mechanisms. We examined changes in an extensive panel of plasma lipids, lipoproteins, and apolipoproteins and whether these changes were independent of weight loss, hemoglobin A1c, and hematocrit in patients treated with empagliflozin versus placebo to better understand the observed cardioprotective effects.
Methods: Post-hoc analyses of two double-blind, placebo-controlled trials, the Empire HF trial including 190 patients with heart failure and reduced ejection fraction and the SIMPLE trial including 90 patients with type 2 diabetes randomized to, respectively, 10 mg and 25 mg empagliflozin daily or placebo for 12 weeks.

Background: Recent evidence from both randomized controlled trials and cohort studies in adults suggests that plasma remnant cholesterol (RC) levels predict cardiovascular disease. In children, studies are scarce, although high levels of RC might represent a marker of early atherosclerotic damage. Thus, the aim of this study was to explore the cardiometabolic risk associated with RC, which extends beyond low-density lipoprotein cholesterol (LDL-c) in children.

Background And Aims: Myocardial infarction is a leading cause of death in individuals with non-alcoholic fatty liver disease (NAFLD). The two diseases share elevated very low-density lipoproteins (VLDL) carrying both triglycerides and cholesterol; however, in NAFLD mainly triglycerides accumulate in liver cells while in myocardial infarction mainly cholesterol accumulates in the atherosclerotic plaque. We hypothesized that VLDL triglycerides preferentially associate with risk of NAFLD, while VLDL cholesterol preferentially associates with risk of myocardial infarction.
