    Abstract

    Background. Atherosclerosis-associated cardiovascular diseases exhibit significant ethnic and regional variability in risk factors. Kazakhstan’s high cardiovascular disease mortality rates necessitate population-specific profiling, particularly given urban-rural disparities and lifestyle differences unique to Central Asia.

    Methods. This cross-sectional study (2023–2024) analyzed 368 Kazakhstani adults stratified by European Atherosclerosis Society risk tiers: low (n=67), high (n=127), and very high risk (very high-risk group, n=174). Assessments included lipid profiles (low density lipoprotein, high density lipoprotein, and apolipoprotein B to apolipoprotein A ratio), lifestyle factors (smoking, diet, physical activity), and residence (urban/rural). Statistical analyses employed multiclass logistic regression (MNLogit) with FDR-adjusted p-values.

    Results. Age (OR=8.01, 95% CI:4.40–14.58, p<0.001), male sex (OR=3.27, CI:1.82–5.88), and smoking (OR=7.19, CI:1.52–34.15) were strongly associated with very high-risk group. Rural residents faced 2.6-fold higher very high-risk group odds (CI:1.52–5.68, p=0.002) versus urban counterparts. Protective effects emerged for physical activity (OR=0.03, CI:0.004–0.32) and female sex (High-Density Lipoprotein: +8.1 mg/dL vs. males, p<0.001). No alcohol association was observed (p=0.836).

    Conclusion. A thorough study of the gender aspect of the development of atherosclerotic pathology is required. Physical activity has a strong protective effect. It is interesting that, according to the comparative analysis of binary variables, rural residents have a higher risk of developing atherosclerosis.

    Abstract

    Background. The aim of this study was to investigate the relationship between the Apolipoprotein B/Apolipoprotein A1 ratio and the risk of metabolically associated fatty liver disease, considering lipid profile variations and determine whether the Apolipoprotein B/Apolipoprotein A1 ratio can serve as an independent predictor of metabolically associated fatty liver disease and its associated cardiovascular risks.

    Methods. A total of 377 patients diagnosed with cardiovascular disease and coexisting metabolically associated fatty liver disease were stratified into high-risk and very high-risk groups based on established clinical and imaging criteria. Lipid profiles, Apolipoprotein B, and Apolipoprotein A1 levels were measured, and their associations with cardiovascular and metabolic parameters were analyzed using correlation and regression models.

    Results. The findings reveal a strong positive correlation between Apolipoprotein B levels and atherogenic lipid markers such as low-density lipoproteins cholesterol and total cholesterol, as well as a moderate correlation with triglycerides. In contrast, Apolipoprotein A1 demonstrated a strong positive association with high-density lipoproteins cholesterol and an inverse correlation with metabolic indicators such as Hemoglobin A1c and glucose, suggesting a potential protective role. The Apolipoprotein B/Apolipoprotein A1 ratio emerged as a more accurate predictor of cardiovascular and metabolic risk than traditional lipid ratios. Furthermore, the Apolipoprotein B/Apolipoprotein A1 ratio was significantly associated with the presence and severity of metabolically associated fatty liver disease, reinforcing its potential utility as a biomarker for metabolic liver disease.

    Conclusion. This study highlights the clinical relevance of incorporating apolipoprotein measurements into the routine assessment of individuals at risk for metabolic and cardiovascular disease.

    Abstract

    Background. Non-alcoholic fatty liver disease and type 2 diabetes mellitus or impaired glucose tolerance are common diseases with a high risk of developing cardiovascular diseases, the leading cause of disability and death. Our aim is to develop new methods for screening, prevention, and treatment of cardiovascular diseases in patients with non-alcoholic fatty liver disease, type 2 diabetes mellitus, and impaired glucose tolerance.

    Methods and methods. This study is single-center, open-label, uncontrolled, diagnostic study. Between 2023 and February 2024, 216 patients with cardiovascular diseases and concomitant non-alcoholic fatty liver disease, type 2 diabetes, and impaired glucose tolerance were selected at Heart Center “University Medical Center” Corporate Fund.

    Results. All examined patients with cardiovascular diseases and concomitant non-alcoholic fatty liver disease showed increased liver enzyme activity. Blood lipid profile indicators were significantly higher than optimal levels for patients with cardiovascular diseases. There was also a significant increase in liver enzymes, C-reactive protein, triglycerides, and lipoproteins in patients with cardiovascular diseases and non-alcoholic fatty liver disease combined with type 2 diabetes and impaired glucose tolerance.

    Conclusion. Liver enzyme activity, C-reactive protein, glucose, and lipid profile analysis showed significant increases in these indicators in patients with cardiovascular diseases and non-alcoholic fatty liver disease, especially in the presence of type 2 diabetes and impaired glucose tolerance. All examined patients showed increased liver enzyme activity and lipid levels, indicating the impact of these diseases on the liver and metabolism.

    Abstract

    Background. Bilirubin is a byproduct of the breakdown of erythrocytes. Bilirubin levels can potentially serve as a biomarker for cardiovascular risk assessment. In this study, we would be investigating most recent manuscripts, published in the last 5 years, that studied association of serum bilirubin level to atherosclerosis progression to elicit how strongly low level of total bilirubin can prognose the disease progression.

    Methods. Using Pubmed search engine, all articles that included
