Mammographic breast density and cardiovascular disease in women. A literature review

The world is searching for new simple and economically available gender-specific markers to improve cardiovascular risk stratification in women. The aim of this review was to analyze the association of mammographic density (MD) with cardiovascular disease (CVD). In low MD, i.e., high relative mammary gland fat content, there is a higher incidence of the main risk factors for CVD: hypertension, hyperlipidemia, hyperglycemia, excess body weight, as well as an increase in the volume of fat depots, visceral and ectopic fat. Low MD is associated with a higher 10-year risk of adverse cardiovascular events such as coronary artery disease, stroke, peripheral arterial disease, revascularization, and heart failure, and may serve as a predictor of their development. Including MD in the Framingham Risk Score model improves its accuracy. Identification of low MD, as a marker of high cardiovascular risk, allows the use of mammography for early detection and prevention of the two most dangerous diseases among the female population — breast cancer and CVD.

Sodium and potassium excretion and its association with cardiovascular disorders in Mexican adults.

Worldwide, as well as in Mexico, the leading cause of death is cardiovascular disease (CVD). Hypertension is the main risk factor for CVD; about 50% of the adult population suffers from this condition. High sodium (Na) intake combined with low potassium (K) intake can trigger cardiovascular disorders such as high blood pressure (BP). The aim of this study was to estimate the mean excretion of Na and K in Mexican adults using a spot urine sample, and its association with cardiovascular disorders. Information on 2,778 adults, 20-59 years of age, who participated in ENSANUT-2016 was analyzed. Na and K were estimated using Tanaka formulae. Biomarkers such as glucose, total cholesterol, triglycerides, HDL cholesterol and LDL cholesterol, and anthropometry were measured. Mean Na was 3,354 mg/day (95%CI: 3,278, 3,429), 1,440 mg/day of K (95%CI: 1,412, 1,469), and the Na-K ratio was 2.4. The excretion of Na was greater in adults with high BP (3,542 mg/day) compared to those with normal BP (3,296 mg/day). In adults with hypertension, excretion of K was 10% greater (1,534 mg/day) than in adults with normal BP (1,357 mg/day). In adults with moderate reduction of renal function, Na excretion was 22% less (2,772 mg/day) than in adults with normal kidney function (3,382 mg/day). The results of this study show that the cardiovascular health of Mexican adults is at risk, as they showed high Na excretion and low K excretion.

Sex differences in the applicability of Western cardiovascular disease risk prediction equations in the Asian population.

Cardiovascular diseases (CVDs) are the most common cause of death, but they can be effectively managed through appropriate prevention and treatment. An important aspect in preventing CVDs is assessing each individual's comprehensive risk profile, for which various risk engines have been developed. The important keys to CVD risk engines are high reliability and accuracy, which show differences in predictability depending on disease status or race. Framingham risk score (FRS) and the atherosclerotic cardiovascular disease risk equations (ASCVD) were applied to the Korean population to assess their suitability. A retrospective cohort study was conducted using National Health Insurance Corporation sample cohort from 2003 to 2015. The enrolled participants over 30 years of age and without CVD followed-up for 10 years. We compared the prediction performance of FRS and ASCVD and calculated the relative importance of each covariate. The AUCs of FRS (men: 0.750; women: 0.748) were higher than those of ASCVD (men: 0.718; women: 0.727) for both sexes (Delong test P <0.01). Goodness of fits (GOF) were poor for all models (Chi-square P < 0.001), especially, underestimation of the risk was pronounced in women. When the men's coefficients were applied to women's data, AUC (0.748; Delong test P<0.01) and the GOF (chi-square P = 0.746) were notably improved in FRS. Hypertension was found to be the most influential variable for CVD, and this is one of the reasons why FRS, having the highest relative weight to blood pressure, showed better performance. When applying existing tools to Korean women, there was a noticeable underestimation. To accurately predict the risk of CVD, it was more appropriate to use FRS with men's coefficient in women. Moreover, hypertension was found to be a main risk factor for CVD.

The Epidemiology of Heart Disease in Brazil Between 2021 and 2022

Introduction: Cardiovascular disease (CVD) is the leading cause of death in Brazil. CVDs are multifactorial pathologies, defined by the combination of genetic, environmental and behavioral factors, and are characterized as one of the main causes of death in Brazil and worldwide. Objectives: To discuss through a literature review the causes and consequences of the main heart diseases and to present the epidemiological results in Brazil of data collected through the DATASUS System between the years 2021 and 2022. The data observed shows the frequency of the six main causes of death from CVD in the Brazilian population. Results: Between 2021 and 2022, IHD and CVD were responsible, respectively, for 32% / 23% of deaths from CVD in the general population in 2021 and 37% / 14% in 2022, being pointed out as the main causes, with the highest prevalence among the male public and the age group between 60 and 79 years, when analyzed by regions and federative units of Brazil, the highest rates were found in the Southeast region, followed by the Northeast region. When analyzing deaths in terms of place of occurrence, it was observed that the majority occurred in the hospital environment, followed by the home environment. Final considerations: CVD is still the leading cause of death in Brazil. Thus, primary prevention of CVD should be a priority, intensifying control of the main risk factors for CVD, which would also affect incidence and improve early diagnosis.

Meta-analysis of risk factors for cardiovascular disease in patients with rheumatoid arthritis.

Cardiovascular disease (CVD) is a common complication of rheumatoid arthritis (RA). We aimed to explore the risk factors for cardiovascular disease in patients with rheumatoid arthritis and provide a scientific basis on effective prevention and treatments for CVD in RA patients. We searched for a combination of the subject words and free words involved arthritis, rheumatoid, CVD, heart disease, vascular disease, risk factors, etc. from China Knowledge Network, Wanfang, Vip, China Biomedical Literature Database, Pubmed, Embase, Web of Science, Cochrane and other databases for documents published in public in 2000-October 2022.RevMan 5.3 and Stata14.0 analysis software was used to perform a meta-analysis of case-control and cohort studies on risk factors of CVDs in patients with RA published from 2000 to 2022.The Egger method was used to determine whether there was publication bias. Seventeen pieces of literature were included in this meta-analysis. We explored the associations between CVD and different clinical characters such as DAS28 score, rheumatoid factor, triglyceride, age, sex, C-reactive protein, total cholesterol (TC), hypertension, and D dimer. High serum levels of C-reactive protein, TC, and D-dimer, as well as hypertension, are the main risk factors for CVD in patients with RA. The OR and 95% CI of C-reactive protein were 2.06 (1.91-2.23), RR and 95% CI of TC were 1.7 (1.49-1.93), RR and 95% CI of hypertension were 3.58 (2.37-5.40), as well as OR and 95% CI of D dimer were 2.83 (1.48-5.40).Our results performed by the meta-analysis were reliable, with low publication bias existed. C-reactive protein, TC, hypertension, and D dimer are the main risk factors for CVD in patients with RA. No protective factors were found.

GeogRaphic and socioecoNomic Distribution of real-world Indian data of home blood pressure monitoring (GRAND Study): Study protocol for an observational study in 18 medical centers across India.

One-fourth of death in India is attributed to cardiovascular disease (CVD) and more than 80% is related to ischemic heart disease and stroke. The main risk factor for CVD is hypertension. Every third person in India suffers from hypertension and the prevalence increased drastically in the past 20 years, especially among the youngest age group of 20 and 44 years. Regardless of being under anti-hypertension medication, the blood pressure (BP) control rate in the country is still low ranging between 6% and 28% only. Assessing the "true BP control rate" should be performed using both clinic BP measurement and out-of-office BP measurement as the latter shows better prognosis for patients' hypertension and CVD outcomes. Home blood pressure monitoring (HBPM) shows superiority over ambulatory BP measurement as multiple measurements can be collected at the patient's convenience. Only limited evidence on HBPM in India is available and it's either lacking in hypertension participants or of a small sample size. This study will investigate the real BP control status among 2000 hypertensive patients from 18 centers in 12 states across Pan-India. The outcome of this study will emphasize the value of establishing BP control management practice guidelines suitable for physicians and help policymakers in building proper strategies for hypertension management to reduce the CVD burden on the health situation in India.

Efficacy of Siwan Traditional Therapy on Erythrocyte Sedimentation Rate, Lipid Profile, and Atherogenic Index as Cardiac Risk Factors Related to Rheumatoid Arthritis.

Background and Objectives: The most frequent cause of mortality in rheumatoid arthritis (RA) patients is cardiovascular disease (CVD). Inflammation, dyslipidemia, and decreased physical activity are some of the main risk factors for CVD. Siwan sand therapy is a type of traditional therapy used in Egypt to treat RA. The approach of this therapy depends on the experience of the healers. The aim of the current study was to compare the effects of three sessions of Siwan traditional therapy to five sessions on common CVD risk factors and physical function in rheumatoid arthritis patients. Materials and Methods: Thirty patients (9 male and 21 female) were assigned into two groups of equal size: group (A) received three sessions of Siwan traditional therapy in the form of a sand bath. Group (B) received the same form of therapy for five days. Erythrocyte sedimentation rate (ESR), lipid profile, atherogenic index of plasma (AIP), and a health assessment questionnaire (HAQ) were measured before and after treatment. Results: There was a significant increase above normal within group (A) for ESR (p = 0.001), triglycerides (TG; p = 0.015), total cholesterol (Tot-Chol; p = 0.0001), and low-density lipoprotein (LDL; p = 0.0001). However, there were no considerable differences in high-density lipoprotein (HDL; p = 0.106), very low-density lipoprotein (VLDL; p = 0.213), AIP (p = 0.648), and HAQ (p = 0.875). For the second group, there were significant changes within group B only in Tot-Chol (p = 0.0001), HDL (p = 0.0001), VLDL (p = 0.0001), AIP (p = 0.008), and HAQ (p = 0.014). There was a significant difference between both groups regarding HDL (p = 0.027), LDL (p = 0.005), AIP (p = 0.029), ESR (p = 0.016), and HAQ (p = 0.036). Conclusions: For RA patients, five days of Siwan traditional therapy caused significant changes regarding inflammation, Tot-Chol, LDL, HDL, AIP, and functional activity when compared to three days of Siwan hot sand therapy.

Probiotic lactic acid bacteria isolated from traditional cameroonian palm wine and corn beer exhibiting cholesterol lowering activity

High serum cholesterol is a risk factor for cardiovascular disease (CVD), leading to many fatalities. Traditional palm wine (Elaeis guineensis) and corn beer are noted as potential sources of probiotic bacteria with cholesterol lowering activity. In this study, we isolated and characterised lactic acid bacteria (LAB) with probiotic and cholesterol lowering properties from these sources. The isolates were identified using API 50 CHL kit and sequencing of 16 S rRNA gene. A hypercholesterolemia model involving three groups of eighteen diet-induced Wistar albino rats was established, and the serum lipid profile was analysed using biochemical kits. The genotypic identification of two best cholesterol lowering LAB revealed that they were strains of Levilactobacillus brevis and Enterococcus faeccium. Their 16 S r RNA gene sequences were deposited in NCBI genbank with the accension numbers ON454506 and ON908682 respectively. These isolates effectively lowered LDL-c and increased HDL-c in rat sera, which are the main risk factors for CVD. These probiotics are potential candidates for functional foods formulation against hypercholesterolemia.

Effect of ACE I/D polymorphism in cardiovascular disease patients

Cardiovascular diseases (CVD) are the cause of the highest mortality rate among noncommunicable diseases, Some of the main risk factors for CVD include smoking, hypertension, high body mass index, lipid metabolism disorders, and diabetes mellitus, according to emerging evidence, Genetics and polymorphisms are thought to play an important role in the occurrence and progression of CVD. A number of 100 subjects were involved in this investigation, 70 of them with CVDs and the other 30 healthy individuals were used as control. The study was conducted to find out the importance of ACE gene polymorphism and biochemical variables in CVDs patients. In addition, the study aimed to investigate the effect of gene polymorphism on CVDs. The comparisons between genotypic frequency of ACE gene polymorphism in control and CVDs patients showed a significant increase (p≤0.005) in DD, ID genotype in CVDs patients compared to control , where II genotype significant decreased in CVDs patients compared to control. Our results show insertion mutation at 550bp only in CVDs patients, this mutation not show in other research.

The role of cholesterol in the regulation of adenosine A2A receptor: A basic and clinical approach

Cardiovascular disease (CVD) is the leading cause of mortality and morbidity worldwide and hypercholesterolemia is one of the main CVD risk factors. During inflammation, adenosine blood concentration increases and activates A2A adenosine receptors (expressed by endothelial cells and lymphocytes), thus producing a protective effect via its vasodilatory and immunosuppressive functions. Conversely, alterations of A2A receptor expression and properties have been found in CVD patients. Cholesterol seems to directly regulate the functional characteristics of this receptor and studies suggest that A2A receptor alterations are also associated with dyslipidemia. In order to study the role of cholesterol in A2A receptor regulation, two approaches are used: 1) basic, via the analysis in cellular models of the effect of cholesterol modulation on A2AR localization and signaling, and 2) clinical, by characterizing A2AR expression and functions in patients with familial hypercholesterolemia (FH) and by studying a possible correlation between A2AR, blood cholesterol levels and patient's clinical status. T cells (CEM) and endothelial cells (HMEC-1) are depleted (Methyl-β-Cyclodextrin) or supplemented with cholesterol (Water Soluble Cholesterol) and stimulated with a selective A2A receptor agonist, Adonis. Ligand interaction and A2A receptor activation are analyzed by western blot, flow cytometry and ELISA, A2AR localization by immunofluorescence and microscopy. 2) FH patients and healthy subjects are selected by age, gender and clinical status. After isolation of peripheral blood mononuclear cells (PBMCs), A2AR expression is analyzed by western blot. 1) Cholesterol depletion in CEM does not affect receptor affinity (KD) for its agonist, but increases its binding capacity (Bmax). 2) Our pilot study on a small cohort of patients shows a decrease in A2A receptor expression compared with healthy subjects and an inverse correlation between A2AR expression and total and LDL cholesterol blood levels. Our results demonstrate that cholesterol modulates A2A receptor and that alterations of A2A properties are associated with hypercholesterolemia, which might help to better understand the high cardiovascular risk in hypercholesterolemia patients.

Estimating the Future Burden of Myocardial Infarction in France Until 2035: An Illness-Death Model-Based Approach.

PurposeIn France, myocardial infarction (MI) was the second leading cause of years of life lost in 2019. Estimating the burden of MI in future years could help policymakers and other actors anticipate care and prevention needs and guide them in public health decision-making.Materials and MethodsUsing data from the French hospital discharge database from 2007 to 2015 (n = 519,400), demographic data, and an illness-death model, we projected incidence, prevalence, number of prevalent cases and mean age of incident MI cases in France. The methodology took into account the age-cohort effect on MI incidence, mortality of healthy and diseased subjects, and the time since disease onset.ResultsProjections highlighted an increase in MI prevalence in men between 2015 and 2035 from 2.52% (95% uncertainty interval (UI): [2.48–2.56]) in 2015 to 4.02% ([3.92–4.12]) in 2035, and from 0.85% ([0.83–0.87]) to 1.44% ([1.38–1.50]) in women. This corresponds to an increase of 365,000 cases between 2015 and 2035 (+81.1%) for men and 146,000 cases for women (+88.0%). The difference in the mean age of incident cases between men and women decreased from 9.52 in 2015 to 5.49 years in 2035.ConclusionOur projections forecast an increase in MI prevalence between 2015 and 2035 in men and women, especially in relatively younger women. Using statistical models such as ours can help assess the impact of prevention campaigns for the main cardiovascular disease risk factors on the future MI prevalence.

Abstract P042: Impact Of Mild Sleep Restriction On Lipid Profile: Influence Of Inflammatory Markers

Introduction: Short sleep duration is associated with an increased risk of cardiovascular disease (CVD). Dyslipidemia is one of the main risk factors for CVD but the influence of sleep duration on this risk factor is, for the moment, inconclusive. Objective: The goal of this study is to test the impact of mild sleep restriction (SR), sustained for 6 wk, on the lipid profile of participants at risk of CVD. Methods: A randomized crossover study was carried out in 64 adults (68% women) aged 20-73 y with a BMI between 19.2-29.9 kg/m 2 . Participants habitually slept ≥7 h/night, verified by 2 wk of wrist actigraphy during screening. Participants underwent 2 sleep conditions of 6 wk each: AS and SR (a reduction of 1.5 h/night relative to AS). Lipid profile was determined from fasted blood samples collected at baseline, wk 3, wk 4 and wk 6 of each phase. In a subset of 34 women, we analyzed inflammatory markers: interleukin- 6 (IL-6), C-reactive protein (CRP) and tumor necrosis factor α (TNF-α). Linear mixed models were used to test the influence of sleep condition on change in lipid profile over time. We further performed Pearson correlations between change in inflammatory markers over each of the the 6-wk phases with lipids measures assessed at endpoint of the respective condition. Results: No effect of sleep condition on change in total cholesterol and triglyceride concentrations (β=0.40±1.80; p=0.83; β=0.43±2.38; p=0.86, respectively) was observed. LDL-C decreased over time, and this was more pronounced in SR compared to AS (β=-3.75±1.59; p=0.019). Similarly, HDL-C decreased over time, and this was less pronounced in SR compared to AS (β=1.78±0.64; p=0.006). Findings were similar in sub-group analyses by sex and menopausal status. Correlation analyses revealed trends for inverse correlations between IL-6 and total cholesterol (r=-0.299; p= 0.096), and LDL-C (r=-0.344; p=0.054) during SR. Also, a decrease in CRP during SR was correlated with higher HDL-C levels at endpoint (r=-0.545; p= 0.002). Conversely, in AS, we only detected a positive correlation between change in CRP and LDL-C at endpoint (r=0.354; p= 0.037). Conclusions: Six weeks of mild sleep restriction does not adversely impact lipid profile. However, this may be a maladaptive response to increases in inflammatory markers after a period of mild sleep restriction. Further studies are needed to confirm these findings.

Cardiovascular Circulatory System and Left Carotid Model: A Fractional Approach to Disease Modeling

Cardiovascular diseases (CVDs) remain the leading cause of death worldwide, according to recent reports from the World Health Organization (WHO). This fact encourages research into the cardiovascular system (CVS) from multiple and different points of view than those given by the medical perspective, highlighting among them the computational and mathematical models that involve experiments much simpler and less expensive to be performed in comparison with in vivo or in vitro heart experiments. However, the CVS is a complex system that needs multidisciplinary knowledge to describe its dynamic models, which help to predict cardiovascular events in patients with heart failure, myocardial or valvular heart disease, so it remains an active area of research. Firstly, this paper presents a novel electrical model of the CVS that extends the classic Windkessel models to the left common carotid artery motivated by the need to have a more complete model from a medical point of view for validation purposes, as well as to describe other cardiovascular phenomena in this area, such as atherosclerosis, one of the main risk factors for CVDs. The model is validated by clinical indices and experimental data obtained from clinical trials performed on a pig. Secondly, as a first step, the goodness of a fractional-order behavior of this model is discussed to characterize different heart diseases through pressure–volume (PV) loops. Unlike other models, it allows us to modify not only the topology, parameters or number of model elements, but also the dynamic by tuning a single parameter, the characteristic differentiation order; consequently, it is expected to provide a valuable insight into this complex system and to support the development of clinical decision systems for CVDs.

Association of Joint Body Weight Profile and Physical Activity with Cardiovascular Disease Risk in Montana Adults

Background: There is much debate surrounding the fat but fit paradox, namely, questioning the extent to which physical fitness protects obese/overweight populations from premature mortality. The purpose of this study was to examine the link between joint body weight (BW) profile and physical activity (PA) (BW.PA) and cardiovascular disease (CVD) risk in adults. Methods: Data for this study came from the 2019 Montana Behavioral Risk Factor Surveillance System (BRFSS). Participants were firstly assigned to one of three BW groups (normal weight, overweight, obese) using CDC BMI criteria, secondly assigned to one of three PA groups (active, insufficiently active, inactive) using self-reported moderate-to-vigorous PA (MVPA), and finally assigned to one of the resulting nine joint BW.PA groups. Three main CVD risk factors (hypertension, hypercholesterolemia, diabetes) were used as separate and then combined outcomes. Logistic regression was employed to estimate the odds of having a CVD risk factor for each BW.PA group, relative to “normal weight and active”. Results: A direct linear trend in odds ratios (ORs) was observed across BW.PA groups for each CVD risk factor, from “normal weight and active” to “obese and inactive”. Fully adjusted regression models showed increased odds of having any of the three CVD risk factors (versus having none) for adults “overweight and active” (OR = 2.22, 95% CI: 1.73 – 2.85) and adults “obese and active” (OR = 4.03, 95% CI: 3.08 – 5.27), compared to those “normal weight and active”. Odds were also significantly (p Conclusion: This study found that BW profile was a strong and consistent predictor of three primary CVD risk factors. Obese adults were much more likely to have CVD risk, regardless of PA participation. Hence, fat but fit may not be a paradox among adults in Montana.

Problems Of Metabolic Syndrome

At the beginning of the third millennium, for mankind, which overcame the epidemic of life-threatening infections during its centuries-old history, the problem of cardiovascular diseases (CVD) came to the fore in relevance among all causes of morbidity and mortality. A significant role in this was played by lifestyle modification associated with limiting physical activity, increasing the calorie content of food, and a steady increase in emotional stress. All of this potentiates the main risk factors for CVD, which are a “negative asset of progress,” namely increased blood pressure (BP), dyslipidemia, diabetes mellitus (DM) and obesity. Since 1988, after G. Reaven's Banting lecture, it is customary to designate the interconnected combination of these pathologies by the single term "metabolic syndrome X".

LONGITUDINAL ASSOCIATION BETWEEN DEPRESSION AND INCIDENT HYPERTENSION-AN UPDATED SYSTEMATIC REVIEW AND META-ANALYSIS

Objective: Background: The association between depression and cardiovascular disease (CVD) is well documented. However, depression has also been proposed to be involved in the pathological pathways linking the main risk factors of CVDs. Several studies including one meta-analysis have suggested that depression may be an independent risk factor for hypertension. Objective:To evaluate the relationship between depression and incident hypertension Design and method: Bibliographic databases Medline, EMBASE, Web of Science and PsycINFO without language restrictions were searched from 2005 up to 2019. We included prospective cohort studies, involving normotensive subjects at baseline with diagnosis of depression measured using clinical evaluation or a standardised psychometric tool and recorded as a dichotomous variable. Outcome was new-onset hypertension. We excluded studies that enrolled participants with a history of antihypertensive medication at the time of study initiation. Methodological quality was assessed using the Newcastle-Ottawa Scale. Pooled hazard ratios (HR) were calculated using inverse variance method in random effects models. Results: We identified five studies with a total of 201,886 participants and an average follow-up of 7.52 years. Out of the five studies, only two reported a positive association between depression and incident hypertension. The pooled effect of three studies included in the meta-analysis showed that depression was associated with 20% increased risk of hypertension (HR = 1.20, 95%CI 1.01–1.43) but with a substantial heterogeneity (I2 = 70%). One study reported a null result for a dose-response relationship between depressive symptoms and incident hypertension. Quality analysis showed increased risk of bias notably in the ascertainment of the outcome as most studies relied on self-report and/or prescription of antihypertensive medication as a proxy for hypertension. Conclusions: Our findings indicate a possible increased risk of hypertension with depressive symptoms, but this result is limited by heterogeneity and ascertainment bias in the studies included.

Current situation and trend of cardiovascular disease burden in China from a global perspective

&lt;p&gt;&lt;strong&gt;Objective&lt;/strong&gt;: Based on the global burden of disease (GBD) 2019 study, to analyze the epidemic trend and risk factors of cardiovascular disease (CVD) in China by comparing the world, the United States, Japan and India. Methods data were obtained from the global health data exchange (ghdx) database. The prevalence, morbidity, mortality, disability adjusted life year (DALY) and other disease burden status and main risk factors of CVD in China were analyzed by sex and age; the age standardized rate was used to compare the change trend of CVD disease burden in China, the United States, Japan and India from 1990 to 2019. &lt;strong&gt;Results&lt;/strong&gt;: In 2019, the number of CVD patients in China was 12 billion, with 123.41 million new cases and 458.43 million deaths; the prevalence, incidence rate, mortality and Daly rates increased from 423,543/100,000, 44,781/100,000, 20,475/100,000 and 509,103/100,000 in 1990 to 84,608/100,000, 86,765/100,000, 32,230/100,000 and 646,347/100,000 in 2019 respectively. The prevalence, incidence rate, mortality and Daly rate increased with age, and the burden of CVD in men was higher than that in women. In addition, the top 4 risk factors for CVD in China in 2019 are hypertension, diet, air pollution and tobacco, which lead to higher CVD disease burden than the global average. &lt;strong&gt;Conclusion&lt;/strong&gt;: due to hypertension, dietary factors, air pollution, tobacco and other reasons, coupled with the rapid aging of the population, the disease burden of CVD in China is still very serious, which needs to be paid attention to by relevant departments.&lt;/p&gt;

Assessment of cardiovascular risk in Kyrgyz Republic

Objective: An analysis of the current situation in the Kyrgyz Republic demonstrates that the areas of concern in care system for patients with cardiovascular diseases (CVD) are the insufficient and untimely identification of cardiovascular risk factors, as well as their ineffective management due to the incomplete implementation of existing risk stratification guidelines and decision-making. This study assesses distribution of total cardiovascular risk among the population of the Kyrgyz Republic using the WHO/ISH risk scale. In addition, the distribution of the main risk factors separately is calculated, as well as the frequency of some additional CVD risk factors that are not included into the WHO/ISH evaluation scale is estimated. Methods: This research was carried out within the framework of the international project "STEPS". The survey used a questionnaire developed by WHO and adapted to the Kyrgyz Republic. Overall, 2417 people were selected at the age of 25 to 65 years, of which 59.0% are women and 41.0% are men. The mean age in general was 43.9 (11.5) years. Of these, mean age for men was 44.0 (11.2) years and for women - 43.8 (11.7) years (p˃0.05). Results: According to the WHO / ISH chart, the proportion of low, medium, high and very high risk for age group of 40-65 years was 73.9%, 4.6% and 21.4%, respectively. According to the results of the study, among respondents aged 40 to 65 years, a high prevalence of the main risk factors for CVD was revealed (arterial hypertension - 61.5%, hypercholesterolemia - 31.6%, smoking - 19.0%, diabetes mellitus 11.1%) and other additional risk factors for CVD (insufficient intake of fruits and vegetables - 75.4%, obesity - 36.5%, physical inactivity - 29.3% and excessive salt intake - 14.0%). Conclusion: Thus, very high-risk of CVD in our population was presented in 21.4% of individuals, while low risk prevailed – 73.9%. The most frequent risk factors were arterial hypertension, hypercholesterolemia, obesity and physical inactivity, insufficient consumption of fruit and vegetables followed by smokin, diabetes and excessive salt consumption.

Alfa2-adrenoblockers attenuate the elevated plasma cholesterol, anxiety levels and restore impaired spatial memory of rats under the chronic noise exposure

Noise is considered one of the environmental hazards that negatively affect health. It can cause damage to the auditory, neurological, hormonal and cardiovascular systems, in addition to impairing psychological and cognitive functions. Considering the significance of vascular disturbances and oxidative stress in the development of the aforementioned negative effects, the purpose of our investigation was to study the level of high density lipoprotein-cholesterol (HDL-Cl), low density lipoprotein-cholesterol (LDL-Cl), and total cholesterol (TCl) in plasma, in addition to the behavioral characteristics of white rats, and the effects of the α2-adrenoblockers beditin and mesedin to reveal their antiatherogenic effect during noise exposure. The “Open field” and “Y-maze” tests were used in order to evaluate the behavioral states of the rats. Investigations were carried out on albino rats divided into 4 groups. The 1st group of rats served as a control. The 2nd, 3rd and 4th groups were exposed to 91 dBA of noise; the duration of exposure was 8 h per day for 60 days. The 3rd group was injected with beditin and the 4th group with mesedin, both intraperitoneally and repeatedly. According to our results, the chronic exposure to high-volume noise leads to the increase of plasma TCl and LDL-Cl concentrations and the decrease of HDL-Cl levels, resulting in increase of the atherogenic coefficient, which is estimated to be one of the main cardiovascular disease risk factors. The “Open field” and “Y-maze” tests revealed that chronic noise exposure caused disturbances in the behavioral activity, a noise duration-dependent delay in movement and orientation, increased anxiety and deficit in the animals’ spatial memory. The administration of α2-adrenoblockers to the noise-exposed animals had a regulatoryeffects of varying intensities, depending on the medication used and the studied parameters under the conditions of chronic acoustic stress.

Cardiovascular Disease Risk Factors among Copper Industry Workers of the Sverdlovsk Region

Introduction. Cardiovascular diseases (CVD) are the leading cause of death in the working-age population including occupational deaths. Materials and methods. We conducted general clinical and biochemical studies among copper industry workers including a complete cholesterol test, blood lead and copper tests, volumetric sphygmography with determination of the cardio-ankle vascular index (CAVI), and ultrasound examination of the carotid arteries with intima-media thickness measurements (IMT). Results. We established that the main cardiovascular disease risk factors among our subjects were smoking (72.2%), different types of obesity (33.3%), total cholesterol levels higher than 4.9 mmol/L (57.9%), fasting hyperglycemia (73.9%), and hypertension stages 1 and 2 (40.7%). We also observed increased arterial stiffness by CAVI in 28.7% of the subjects that became more prevalent with the rise in the total CVD risk by SCORE (p=0.00105). Conclusions. We found correlations between CAVI and blood copper levels (r=0.33), years of exposure to occupational risk factors (r=0.187), and IMT (r=0.41). This finding enabled us to recommend the use of CAVI for identification and follow-up of workers at risk of cardiovascular diseases with a simultaneous decrease in exposures to occupational risk factors.
