Ischemic heart disease (IHD) remains a leading cause of morbidity and mortality worldwide. Metabolic syndrome (MetS), a cluster of interrelated metabolic abnormalities including central obesity, insulin resistance, hypertension, dyslipidemia, and impaired glucose metabolism, has emerged as a major contributor to the development and progression of IHD. The presence of MetS significantly increases cardiovascular risk and worsens clinical outcomes in patients with established coronary artery disease.
We summarize current evidence on the role of metabolic syndrome in ischemic heart disease, with a focus on underlying pathophysiological mechanisms and clinical implications. Key mechanisms linking MetS to IHD include insulin resistance, endothelial dysfunction, chronic low-grade inflammation, oxidative stress, atherogenic dyslipidemia, and pro-thrombotic states, all of which promote atherosclerosis and plaque instability. In addition, emerging biomarkers such as high-sensitivity C-reactive protein (hs-CRP), lipoprotein-associated phospholipase A₂ (Lp-PLA₂), adipokines, and inflammatory cytokines provide further insight into the complex interaction between metabolic disturbances and ischemic heart disease.
Understanding the role of metabolic syndrome in IHD is essential for early risk stratification and targeted prevention strategies. Comprehensive management of metabolic syndrome components may reduce the incidence, severity, and recurrence of ischemic heart disease. This review highlights the importance of an integrated metabolic and cardiovascular approach in the prevention and management of IHD.

Background: Lower respiratory tract infections, specifically pneumonia, are a leading cause of morbidity in children and are predominantly caused by viral and bacterial pathogens. Researchers worldwide have reported that the etiology of pneumonia varies significantly with age, noting an increasing incidence of Mycoplasma pneumoniae pneumonia (MPP) among children over five years of age. In the context of Mongolia, investigating the incidence, clinical presentation, and laboratory and diagnostic imaging characteristics of MPP is essential. Understanding these specific features will facilitate early detection and optimal treatment, preventing potential complications. Furthermore, this research aims to reduce the unnecessary use of antibiotics by ensuring accurate diagnosis, which serves as the primary rationale for this study. Aim: To investigate the clinical characteristics of Mycoplasma pneumoniae pneumonia (MPP) in relation to laboratory findings and diagnostic imaging changes. Materials and Methods: A retrospective study was conducted at the Pediatric Ward of the National Center for Maternal and Child Health-2 (NCMCH-2). Data were collected using quantitative methods. Information from patient questionnaires, physical examinations, and laboratory test results were coded for analysis. Statistical analysis was performed using Microsoft Excel and SPSS version 30.0. Results: Analysis of the pathogens causing pneumonia across different age groups revealed that mixed viral and bacterial co-infections predominated in younger children. Conversely, bacterial infections became the primary cause as age increased, indicating a significant age-dependent variation in pathogen distribution (p=0.00054). Based on PCR testing, Mycoplasma pneumoniae (MP) was the most frequently detected pathogen, identified in 51.8% (55) of cases. The mean age of children positive for MP was 9.4 ± 4.4 years. Among these cases, only 25% (14) presented as MP monoinfection, while 75% (51) involved co-infections with other bacterial and viral pathogens. Conclusions 1. Mycoplasma pneumoniae was identified as the most prevalent bacterial pathogen (51.8%) among children hospitalized with pneumonia, indicating a high incidence of pneumonia caused by this bacterium during the late months of 2024. 2. Mycoplasma pneumoniae infection primarily affects school-aged children (mean age 9.2 years). Despite presenting with abnormal breath sounds upon auscultation requiring hospitalization, children positive for MP exhibited normal oxygen saturation and normal inflammatory markers in the blood compared to the MP-negative group. This highlight the classic «atypical» nature of the pathogen. Furthermore, clinical manifestations vary across age groups; specifically, upper respiratory symptoms such as rhinorrhea predominate in younger children (likely due to viral co-infection), whereas these symptoms significantly decrease in older children, in whom lower respiratory tract symptoms become dominant.

Background: Cardiovascular disease (CVD) remains the leading cause of death worldwide, accounting for approximately 19.8 million deaths in 2022, or 32% of all deaths. Insulin resistance is an important pathophysiological mechanism not only in the development of type 2 diabetes mellitus (T2DM) but also in the development and progression of cardiovascular disease. Evidence remains limited regarding the simultaneous assessment of associations between selected anthropometric measures and insulin resistance in patients with ischemic heart disease (IHD). Aim: To investigate the association between waist-to-height ratio (WHtR) and insulin resistance indices (TG/HDL and HOMA-IR) in patients with chronic ischemic heart disease. Materials and Methods: This hospital-based cross-sectional study included 274 patients aged 40–75 years. Written informed consent was obtained from all participants. Data were collected using a structured questionnaire, anthropometric measurements were performed, and peripheral blood samples were collected. Laboratory measurements included fasting lipid profile, fasting glucose, and fasting insulin levels. WHtR was calculated as waist circumference (cm) divided by height (cm). Insulin resistance was assessed using the TG/HDL ratio, calculated as TG (mmol/L) divided by HDL (mmol/L), and the HOMA-IR index. Metabolic syndrome was defined according to the Joint Interim Statement (JIS-2009) criteria. Results: Among the 274 participants, 209 (76.3%) were male and 65 (23.7%) were female, with a mean age of 61.1±7.9 years. WHtR was significantly and positively correlated with HOMA-IR, with a weak-to-moderate correlation (Spearman’s ρ=0.303, p<0.001). A weak but statistically significant positive correlation was also observed between WHtR and the TG/HDL ratio (ρ=0.136, p=0.039). The discriminative ability of WHtR for insulin resistance was moderate (AUC=0.645, 95% CI: 0.562–0.729; p=0.001). The optimal cutoff value determined using the Youden index was 0.60, with a sensitivity of 63.2% and specificity of 64.2%. Multivariable logistic regression analysis showed that WHtR ≥0.60 was independently associated with insulin resistance. Conclusion WHtR was significantly and positively associated with HOMA-IR and the TG/HDL ratio, and WHtR ≥0.60 was independently associated with insulin resistance.

Cardiovascular diseases related death rates have been declining over, but during the two decades, mortality and morbidity attributable by cardiovascular diseases are continuously taking the first place among the leading causes of morbidity and deaths among the population. Statistics show that >4 million people die each year from cardiovascular disease (CVD) causes in Europe. The World Health Organization reports that in less developed and developing countries, obesity and mortality are expected to continue to increase, depending on the age of the population and the characteristics of lifestyle.
Dyslipidaemia is characterized by elevated low-density lipoprotein cholesterol (LDL-C) and decreased high-density lipoprotein cholesterol (HDL-C) and is a known risk factor for development and progression of atherosclerosis in CAD.
Dyslipidemia and hypertension are major risk factors for cardiovascular disease (CVD) and account for more than 80% of deaths and disability in low- and middle-income countries. Increased serum levels of total cholesterol (TC), triglycerides (TG), high-density lipid (HDL)-cholesterol and decreased low-density lipid (LDL)-cholesterol are known to be associated with major risk factors for CVD. The Framingham study and others that followed could show that HDL-C is an independent cardiovascular risk factor and that the increase of HDL-C of only 10 mg·L(-1) leads to a risk reduction of 2-3%. A recent meta-analysis, including 302.430 subjects from 68 long-term prospective studies, supported the importance of HDL-C measurement in the risk assessment for CAD.
However, data about the relationship between cardiovascular disease and lipid profile among Mongolian adult are rare in the literature. In recent years, rapid urbanization, unhealthy diet, increased life expectancy and lifestyle changes have led to an increased rate of CVD around the world.
