Metabolic Blood Hormones in Young People With Electrocardiographic Signs of Ischemic Myocardial Changes.

Aim    To study changes in blood concentrations of metabolic hormones and adipocytokines in people aged 25-44 years with electrocardiographic (ECG) signs of ischemic changes in the myocardium.Material and methods This study was a part of a cross-sectional survey of a random sample of Novosibirsk population aged 25-44 years. The study included 1363 people divided into two groups: group 1, subjects with ECG signs of ischemic changes in the myocardium and group 2, subjects without ECG changes.

Associations of adipokines and metabolic hormones with low-density lipoprotein hypercholesterolemia in men and women under 45 years of age.

Aim    To study the adipokine profile in young people with hypercholesterolemia and low-density lipoproteins (LDL) and to evaluate the relationship between concentrations of LDL cholesterol (LDL-C) and metabolic hormones in men and women younger than 45 years. Material and methods    This study included 304 subjects (group 1, 56 men with LDL-C concentration <2.1 mmol/l; group 2, 87 men with LDL-C concentration ≥4.

The Search for Associations of Serum Proteins with the Presence of Unstable Atherosclerotic Plaque in Coronary Atherosclerosis.

To study the associations of blood proteins with the presence of unstable atherosclerotic plaques in the arteries of patients with coronary atherosclerosis using quantitative proteomics. The studies involved two groups of men with coronary atherosclerosis (group 1 (St) had only stable atherosclerotic plaques; group 2 (Ns) had only unstable atherosclerotic plaques, according to histological analysis of tissue samples); the average age of patients was 57.95 ± 7.

The Influence of Calcification Factors and Endothelial-Dysfunction Factors on the Development of Unstable Atherosclerotic Plaques.

Background: This study aimed to evaluate changes in markers of calcification and of endothelial dysfunction during the development of calcification and instability of atherosclerotic plaques and to identify associations of calcification factors with the formation of unstable plaques.

Methods: We analyzed 44 male patients with coronary atherosclerosis who underwent endarterectomy in coronary arteries during coronary bypass surgery. The endarterectomy material (intima/media) was examined using histological and biochemical methods, and the stability and calcification degree of atherosclerotic plaques were assessed.

[The Study of Biochemical Factors of Calcification of Stable and Unstable Plaques in the Coronary Arteries of Man].

Objective: The aim of the study was to study biochemical factors of calcification in stable and unstable plaques of coronary arteries and in the blood of patients with severe coronary atherosclerosis, to find associations of biochemical factors of calcification with the development of unstable atherosclerotic plaque.

Materials And Methods: The study included 25 men aged 60,4±6,8 years who received coronary bypass surgery. In the course of the operation intraoperative indications in men were from coronary endarteriectomy (s) artery (a - d) and histological and biochemical analyses of the samples of the intima / media.
