Dynamics of lipoprotein oxidation in blood plasma was studied by Cu-induced plasma oxidation in 114 patients with atherosclerosis of lower extremities of various severity with and without ischemic heart disease. Preparedness of plasma lipoproteins to oxidation in patients was higher than in healthy subjects. Degree of oxidizeability increased with increase of severity and extent of atherosclerosis and was highest in patients with atherosclerosis of lower extremities and ischemic heart disease. There were no significant differences between groups of patients with various severity and extent of atherosclerosis in levels of total cholesterol and triglycerides as well as in other parameters of lipid spectrum. Correlation analysis revealed no relationship between age of patients and degree of plasma oxidizeability.

Purpose: Epicardial adipose tissue (EAT) could contribute to the specific atherosclerosis profile observed in premature coronary artery disease (pCAD) characterized by accelerated plaque burden (calcified and non-calcified), high risk plaque features (HRP) and ischemic recurrence. Our aims were to describe EAT volume and density in pCAD compared to asymptomatic individuals matched on CV risk factors and to study their relationship with coronary plaque severity extension and vulnerability.
Materials And Methods: 208 patients who underwent coronary computed tomography angiography (CCTA) were analyzed.

Background: Early neurological deterioration (END) is a critical determinant influencing the short-term prognosis of acute ischemic stroke (AIS) patients and is associated with increased mortality rates among hospitalized individuals. AIS frequently coexists with coronary heart disease (CHD), complicating treatment and leading to more severe symptoms and worse outcomes. Shared risk factors between CHD and AIS, especially elevated low-density lipoprotein cholesterol (LDL-C), contribute to atherosclerosis and inflammation, which worsen brain tissue damage.

FoxP3 T-regulatory (Treg) lymphocytes and cytokine production by cells from the stromal vascular fraction (SVF) of epicardial (EAT) and thymus (TAT) adipose tissue of 42 patients with chronic coronary heart disease (CHD) were studied. In the SVF of TAT in patients with Gensini Score (GS)≥74 (the most severe atherosclerosis), the production of IL-1β, TNF, IL-4, and IFNγ was higher, while FoxP3 translocation into the nucleus was lower than in patients with GS<74. The GS index directly correlated with the production of IL-4, IL-1β, and TNF by cells of the SVF of TAT, and inversely - with the production of TNF, IL-17, and IL-10 by cells of the SVF of EAT.

Background: Atherosclerosis is a lipid-driven, systemic immune-inflammatory disease characterized by the accumulation of plaque within the arterial walls. Plaque regression can occur following appropriate treatment interventions. Optical coherence tomography (OCT), a high-resolution imaging modality, is frequently employed to assess plaque morphology.

Phytoestrogens are plant-derived compounds resembling human estrogen and have recently gained attention due to their potential role in improving cardiovascular health. These compounds exert their effects through various mechanisms, including interactions with estrogen receptors, growth factor receptors, inflammatory mediators, thrombogenic reactions, and apoptotic pathways. This results in cardioprotective effects like modulating endothelial function, decreasing vessel tone, reducing inflammation, altering lipid profiles, and influencing arrhythmogenesis.
