Kenaf Seed Cysteine Protease (KSCP) Inhibits the Intrinsic Pathway of the Blood Coagulation Cascade and Platelet Aggregation.

Thrombosis is the key event that obstructs the flow of blood throughout the circulatory system, leading to stroke, myocardial infarction and severe cardiovascular complications. Currently, available antithrombotic drugs trigger several life-threatening side effects. Antithrombotic agents from natural sources devoid of adverse effects are grabbing high attention. In our previous study, we reported the antioxidant, anticoagulant and antiplatelet properties of kenaf seed protein extract. Therefore, in the current study, purification and characterization of cysteine protease from kenaf seed protein extract responsible for potential antithrombotic activity was undertaken. Purification of KSCP (Kenaf Seed Cysteine Protease) was carried out using gel permeation and ion exchange column chromatography. The purity of the enzyme was evaluated by SDS PAGE (Sodium Dodecyl-Sulfate Polyacrylamide Gel Electrophoresis). RP-HPLC (Reverse Phase High-Performance Liquid Chromatography), MALDI-TOF (Matrix-Assisted Laser Desorption Ionization Time-Of-Flight) and CD (Circular Dichroism techniques) were employed for its characterization. Proteolytic, fibrinolytic and kinetic study was done using spectroscopy. Plasma recalcification time, Prothrombin Time (PT), Thrombin clotting time (TCT), Activated Partial Thromboplastin Time (APTT), bleeding time and platelet aggregation studies were carried out for antithrombotic activity of KSCP. A single sharp band of KSCP was observed under both reduced and non-reduced conditions, having a molecular mass of 24.1667kDa. KSCP was found to contain 30.3% helix turns and 69.7% random coils without a beta-pleated sheet. KSCP digested casein and fibrin, and its activity was inhibited by iodoacetic acid (IAA). KSCP was optimally active at pH 6.0 at the temperature of 40°C. KSCP exhibited anticoagulant properties by interfering in the intrinsic pathway of the blood coagulation cascade. Furthermore, KSCP dissolved both whole blood and plasma clots and platelet aggregation. KSCP purified from kenaf seed extract showed antithrombotic potential. Hence, it could be a better candidate for the management of thrombotic complications.

Clinical case of management of a patient with Duchenne muscular dystrophy caused by deletion of exons 50–52 of the DMD gene against the background of pathogenetic therapy with viltolarsen

Duchenne muscular dystrophy (DMD) is the most common lumbar-limb muscular dystrophy with an X-linked recessive type of inheritance. It is characterized by a debut at an early age, rapidly progressive atrophy of the striated musculature of the limbs, trunk, heart muscle, which leads to loss of motor skills, severe cardiovascular and respiratory complications.
 Currently, a number of new drugs have appeared for the pathogenic therapy of MDD, the effectiveness of which is the most during its early initiation in the ambulatory stage of the disease. One of the new methods of MDD treatment is antisense oligonucleotide therapy. The application of this type of therapy is possible for certain mutations in the DMD gene and is recommended immediately after diagnosis. At the moment, the duration of this method of treatment in the Russian Federation is only a few years.
 In our article we discuss a clinical case of the study of a patient suffering from Duchenne muscular dystrophy caused by the deletion of 50–52 exons in the DMD gene, who is on therapy with steroids and Viltolarsen.
 A special feature of the case is the late application of Viltolarsen from the age of 9 years. The results of the observation demonstrate a significant effect in stabilization of motor skills, of the functioning of the cardiovascular and respiratory systems, which gives a chance to slow down the course of the disease, improve the quality of life and increase its duration, even taking into account the late initiation of pathogenic therapy.

Association between neutrophil-to-lymphocyte ratio and outcomes in hospitalized patients with left ventricular thrombus.

Left ventricular thrombus (LVT) is a severe cardiovascular complication occurring in approximately 10% of patients with acute anterior ST-segment elevation myocardial infarction. This study aimed to evaluate the association between neutrophil-to-lymphocyte ratio (NLR) and in-hospital major adverse cardiovascular and cerebrovascular events (MACCE) in patients with LVT. This multicenter retrospective study was conducted between January 2000 and June 2022 in hospitalized patients with LVT. The outcome included in-hospital MACCE. The association between NLR and in-hospital MACCE was measured by odds ratios (ORs). The restricted cubic spline model was used for dose-response analysis. A total of 197 LVT patients from four centers were included for analysis in this study. MACCE occurred in 13.7% (27/197) of the patients. After adjusting for estimated glomerular filtration rate (eGFR), D-dimer, and age, the OR for MACCE comparing first to the third tertile of NLR was 13.93 [95% confidence interval: 2.37-81.77, P = 0.004, P -trend = 0.008]. When further adjusting for etiology and heart failure with reduced ejection fraction (HFrEF), the association remained statistically significant. Spline regression models showed an increasing trend in the incidence of MACCEs with NLR both in crude and adjusted models. Subgroup analyses showed that a high NLR may be correlated with poorer outcomes for LVT patients older than 65 years, or with hypertension, dyslipidemia, low ejection fraction, liver, and renal dysfunctions. In conclusion, these findings suggested that higher NLR may be associated with an increased risk of in-hospital MACCE in patients with LVT.

New Insights into Endothelial Dysfunction in Cardiometabolic Diseases: Potential Mechanisms and Clinical Implications.

The endothelium is a monocellular layer covering the inner surface of blood vessels. It maintains vascular homeostasis regulating vascular tone and permeability and exerts anti-inflammatory, antioxidant, anti-proliferative, and anti-thrombotic functions. When the endothelium is exposed to detrimental stimuli including hyperglycemia, hyperlipidemia, and neurohormonal imbalance, different biological pathways are activated leading to oxidative stress, endothelial dysfunction, increased secretion of adipokines, cytokines, endothelin-1, and fibroblast growth factor, and reduced nitric oxide production, leading eventually to a loss of integrity. Endothelial dysfunction has emerged as a hallmark of dysmetabolic vascular impairment and contributes to detrimental effects on cardiac metabolism and diastolic dysfunction, and to the development of cardiovascular diseases including heart failure. Different biomarkers of endothelial dysfunction have been proposed to predict cardiovascular diseases in order to identify microvascular and macrovascular damage and the development of atherosclerosis, particularly in metabolic disorders. Endothelial dysfunction also plays an important role in the development of severe COVID-19 and cardiovascular complications in dysmetabolic patients after SARS-CoV-2 infection. In this review, we will discuss the biological mechanisms involved in endothelial dysregulation in the context of cardiometabolic diseases as well as the available and promising biomarkers of endothelial dysfunction in clinical practice.

Risk factors and prediction models for cardiovascular complications of hypertension in older adults with machine learning: A cross-sectional study

BackgroundHypertension has emerged as a chronic disease prevalent worldwide that may cause severe cardiovascular complications, particularly in older patients. However, there is a paucity of studies that use risk factors and prediction models for cardiovascular complications associated with hypertension in older adults. ObjectivesTo identify the risk factors and develop prediction models for cardiovascular complications among older patients with hypertension. MethodsA convenience sample of 476 older patients with hypertension was recruited from a university-affiliated hospital in China. Demographic data, clinical physiological indicators, regulatory emotional self-efficacy, medication adherence, and lifestyle information were collected from participants. Binary logistic regression analysis was performed to screen for preliminary risk factors associated with cardiovascular complications. Two machine learning methods, Back-Propagation neural network, and random forest were applied to develop prediction models for cardiovascular complications among the study cohort. The sensitivity, specificity, accuracy, receiver operating characteristic curve, and area under the curve (AUC) values were used to assess the performance of the prediction models. ResultsBinary logistic regression identified nine risk factors for cardiovascular complications among older patients with hypertension. The machine learning models displayed excellent performance in predicting cardiovascular complications, with the random forest model (AUC 0.954) outperforming the Back-Propagation neural network model (AUC 0.811), as confirmed by model comparison analysis. The sensitivity, specificity and accuracy of the Back-Propagation neural network model compared to the random forest model were 74.2% vs. 86.5%, 75.2% vs. 94.3%, and 74.7% vs. 90.4%, respectively. ConclusionThe machine learning methods employed in this study demonstrated feasibility in predicting cardiovascular complications among older patients with hypertension, with the random forest model based on nine risk factors exhibiting excellent prediction performance. These models could be used to identify high-risk populations and suggest early interventions aimed at preventing cardiovascular complications in such cohorts.

Role of vaccination in patients with human monkeypox virus and its cardiovascular manifestations.

Human monkeypox, caused by the monkeypox virus (MPXV), is an emerging infectious disease with the potential for human-to-human transmission and diverse clinical presentations. While generally considered milder than smallpox, it can lead to severe cardiovascular complications. The virus primarily spreads through contact with infected animals or through human-to-human transmission. Cardiovascular involvement in human monkeypox is rare but has been associated with myocarditis, pericarditis, arrhythmias, and even fulminant myocardial infarction. Vaccination plays a crucial role in preventing and controlling monkeypox, but the eradication of smallpox has left global populations vulnerable. This review explores the cardiovascular manifestations of human monkeypox, the role of vaccination in disease prevention, and the importance of continued research and development of effective vaccines to protect against this emerging infectious threat. The global impact of monkeypox outbreaks, particularly on vulnerable populations, further highlights the importance of understanding and addressing this disease.

Long-term air pollution exposure is associated with higher incidence of ST-elevation myocardial infarction and in-hospital cardiogenic shock

Previous studies have reported the association between myocardial infarction (MI) and air pollution (AP). However, limited information is available regarding the long-term effects of AP on the relative incidence rates of ST-elevation MI (STEMI) and Non-ST-elevation MI (NSTEMI). We investigated the association between long-term exposure to AP and the incidence of STEMI. Between January 2006 and December 2015, a total of 45,619 eligible patients with Acute Myocardial Infarction (AMI) were enrolled in the Korea Acute MI Registry (KAMIR) and KAMIR-National Institutes of Health. Mixed-effect regression models were used to examine the association between the annual average ambient AP before MI onset and the incidence of STEMI, and to evaluate the association of AP with the incidence of in-hospital cardiogenic shock. After mixed-effect regression model analysis, particulate matter (PM) 10 µm or less in diameter (PM10) was associated with increased incidence of STEMI compared with NSTEMI (odds ratio [OR] 1.009, 95% Confidence Interval [CI] 1.002–1.016; p = 0.012). For in-hospital cardiogenic shock complication, PM10 and SO2 were associated with increased risk, PM10 (OR 1.033, 95% CI 1.018–1.050; p < 0.001), SO2 (OR 1.104, 95% CI 1.006–1.212; p = 0.037), respectively. Policy-level strategies and clinical efforts to reduce AP exposure are necessary to prevent the incidence of STEMI and severe cardiovascular complications.

Association between left ventricular remodeling and lipid profiles in obese children: an observational study.

Childhood obesity has become a prominent issue in the society, which can lead to left ventricular remodeling and severe cardiovascular complications in adulthood. It is beneficial to identify the causes of left ventricular remodeling so that targeted measures can be taken to prevent the cardiovascular disease. Therefore, this study aimed to explore the relationship between left ventricular remodeling and changes in blood lipid indexes in obese children. This study was conducted on 40 healthy non-obese children and 140 obese children diagnosed in the pediatric health department of our hospital. Clinical data collected from the two groups were compared. Echocardiography was performed to examine left ventricular configuration and cardiac function. Multiple linear regression analysis was conducted to assess the independent effects of blood lipid levels on echocardiographic parameters. Blood lipid indicators among different left ventricular structural patterns which were classified according to left ventricular mass indexes and relative wall thickness were compared. Obese children exhibited significantly increased height, weight, body mass index (BMI), body fat percentage (BFP), blood pressure, triglycerides, total cholesterol, left ventricular internal diameter (LVIDd), interventricular septum (IVSd), left ventricular posterior wall diastolic thickness (LVPWd), myocardial mass (LVM) and relative wall thickness (RWT), as well as lower high-density lipoprotein cholesterol (HDL-C) and left ventricular ejection fraction (LVEF) compared to the non-obese children (P < 0.05). Multiple linear correlation analysis showed LVM had a significantly positive correlation with BMI (r = 3.21, P = 0.002) and SBP (r = 2.61, P = 0.01); LVMI had a significantly negative correlation with HDL-C (r = -2.45, P = 0.015); RWT had a significantly positive correlation with SBP (r = 2.50, P = 0.013) but a significantly negative correlation with HDL-C (r = -2.35, P = 0.02). Furthermore, there were significant differences in HDL-C values among children with different ventricular configurations (P < 0.05), with the lowest HDL-C value recorded in the concentric hypertrophy group. Obese children will develop left ventricular remodeling. The left ventricular configuration indexes are most significantly associated with serum HDL-C. Lower HDL-C level contributes to severer left ventricular hypertrophy, indicating a concentric hypertrophy pattern.

A Narrative Review of Pheochromocytoma in VHL.

This systematic review aims to investigate the clinical presentation, diagnostic methods, and management strategies for pheochromocytoma in patients with von Hippel-Lindau (VHL) disease, an autosomal dominant disorder that predisposes individuals to the development of various tumors, including pheochromocytomas. Pheochromocytoma is a rare neuroendocrine tumor of the adrenal medulla that occurs sporadically or as part of an inherited syndrome. The incidence of pheochromocytoma in VHL patients is estimated to be between 10-20%, making it the second most common tumor associated with VHL. Early detection and management of pheochromocytoma in VHL patients are critical for patient outcomes, as these tumors can cause severe hypertension, cardiovascular complications, and death. This review highlights the importance of screening for pheochromocytoma in VHL patients and discusses the current diagnostic and management strategies to optimize patient care.

Long QT syndrome induced by elevated dose of Fluoxetine Cloridrate: case report

Introduction: Long QT syndrome is a clinical condition that affects cardiac repolarization with an increased risk for the development of severe ventricular arrhythmias. The acquired form can be induced by drugs, such as selective serotonin reuptake inhibitors. Case report: E.A.C.G., female, 83 years-old, previously diagnosed with major depressive disorder in use of Fluoxetine the 80mg/day, was admitted in the emergency department after a syncopal event. An important widening of the QT interval was noted on the occasion, with a corrected value of 580ms. A 24-hour Holter monitoring showed increased ectopic ventricular activity (18% of beats), prolonged QT interval (up to 630 ms), and high-complexity ectopic ventricular beats. Non-sustained ventricular tachycardia was also observed (1030 episodes). The prolonged QT interval was associated to an elevated dose of Fluoxetine. Discussion: We believe that the coexistence between a high dose of Fluoxetine and other risk factor such as female sex and increased age contributed to the development of the case presentation. Conclusion: The rising prevalence of depression in the geriatric population and the indiscriminate use of antidepressive agents such as selective serotonin reuptake inhibitors may contribute to an increase in potentially severe cardiovascular complications.

The Potential Mechanisms of Arrhythmia in Coronavirus disease-2019.

Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) leads to coronavirus disease-2019 (COVID-19) which can cause severe cardiovascular complications including myocardial injury, arrhythmias, acute coronary syndrome and others. Among these complications, arrhythmias are considered serious and life-threatening. Although arrhythmias have been associated with factors such as direct virus invasion leading to myocardial injury, myocarditis, immune response disorder, cytokine storms, myocardial ischemia/hypoxia, electrolyte abnormalities, intravascular volume imbalances, drug interactions, side effects of COVID-19 vaccines and autonomic nervous system dysfunction, the exact mechanisms of arrhythmic complications in patients with COVID-19 are complex and not well understood. In the present review, the literature was extensively searched to investigate the potential mechanisms of arrhythmias in patients with COVID-19. The aim of the current review is to provide clinicians with a comprehensive foundation for the prevention and treatment of arrhythmias associated with long COVID-19.

Monoclonal Gammopathy of Undetermined Cardiovascular Significance; Current Evidence and Novel Insights.

Monoclonal gammopathy of undetermined significance (MGUS) is a premalignant condition characterized by the presence of low levels of a monoclonal protein in the serum and a low percentage of clonal plasma cells in the bone marrow. MGUS may progress to multiple myeloma or other plasma cell disorders at a rate of 1% annually. However, MGUS may also have adverse effects on the cardiovascular system independent of its malignant potential. Emerging data have shown that MGUS is associated with cardiovascular disease. The mechanisms underlying this association are not fully understood but may involve genetic abnormalities, vascular calcification, cryoglobulinemia, cold agglutinin disease, autoantibodies and the direct or indirect effects of the monoclonal protein on the vascular endothelium. Herein, we review current evidence in this field and we suggest that patients with MGUS may benefit from regular cardiovascular risk assessment to prevent severe cardiovascular complications, in parallel with close hematological follow-up to monitor potential disease progression.

Permanent pacemaker implantations among patients with spinal cord injury in the United States

Abstract Background Acute spinal cord injury (SCI) is associated with severe cardiovascular complications. Information regarding the need for permanent cardiac pacing in SCI patients is scarce and based on case reports and small case series. We aimed to investigate the extent of permanent pacemaker (PPM) implantation procedures as well as to identify predictors for PPM insertion among SCI patients in a U.S contemporary, nationwide, all-comer registry. Methods Using the National Inpatient Sample (NIS) database, patients hospitalized with a primary diagnosis of SCI in the US between 2016-2019 and underwent PPM implantation were identified. Patients with cardiac implantable electronic device in-situ were excluded. Baseline demographics, clinical characteristics, injury type, in-hospital procedures and outcomes including time to PPM implantation, length of stay and mortality were collected. Outcome analysis performed after propensity score matching (PSM). Predictors of PPM implantation were identified via a multivariable logistic regression model. Results A total of 35880 patients, were hospitalized with a primary diagnosis of SCI during the study period, and 240 (0.7%) received a PPM. Median age of patients receiving PPM was 69 years, 75% were males, and 67% had high level SCI injury (level C1-5). Time to PPM implantation was 9 days (IQR 4-19). PPM implantation was associated with higher rates of cervical spine injuries, traumatic brain injury (TBI), chest and upper limbs injuries, respiratory failure and other signs of severe illness. Longer hospital stay and higher in-hospital mortality rate was observed in patients receiving a PPM. Multivariate analysis identified the following independent risk factors for PPM implantation: cervical SCI [OR 77.07 (11.13-553.42), p&amp;lt;0.001], TBI [OR 3.84(1.59-9.28), p=0.003] and tracheostomy/respiratory ventilation&amp;gt; 96 h [OR 31.766(7.91-127.54), p=&amp;lt;0.001]. Conclusion Cervical SCI, need for tracheostomy and prolonged mechanical ventilation were the strongest predictors for PPM implantation in patients hospitalized for SCI in a nationwide registry.

LONG-TERM CARDIOVASCULAR EFFECTS OF COVID-19: A COMPARATIVE STUDY

The COVID-19 pandemic has left a lasting impact on global health, with increasing evidence of long-term cardiovascular consequences in affected individuals. This study aims to comprehensively investigate and compare the persistent cardiovascular effects of COVID-19 across a diverse population, shedding light on the implications for long-term public health management. The primary objective of this comparative study is to assess and compare the long-term cardiovascular sequelae in COVID-19 survivors across various demographics and disease severities. We seek to understand the extent of cardiovascular involvement, associated risk factors, and outcome variations to inform clinical strategies and public health interventions. We conducted a multi-center retrospective analysis of electronic health records and patient data from diverse geographical regions and demographic groups. Our study involved a large cohort of COVID-19 survivors, categorizing them based on age, sex, comorbidities, and disease severity. We utilized comprehensive cardiovascular assessments, including echocardiography, electrocardiography, and biomarker analysis, to evaluate the cardiovascular status of participants. Our findings revealed long-term cardiovascular effects in COVID-19 survivors, including myocardial injury, arrhythmias, vascular abnormalities, and thrombotic events. These effects varied significantly among different demographic groups and were strongly associated with disease severity and pre-existing comorbidities. Older individuals and those with pre-existing cardiovascular conditions exhibited a higher risk of developing severe cardiovascular complications post-COVID-19. This comparative study underscores the substantial burden of long-term cardiovascular effects in COVID-19 survivors and the need for tailored healthcare interventions. The results emphasize the importance of continuous monitoring and risk assessment, particularly among older adults and individuals with pre-existing cardiovascular conditions. These findings have critical implications for long-term public health management strategies, including vaccination campaigns, prevention programs, and post-COVID-19 care pathways.

Progress in studying the impact of hyperlipidemia and statins on rotator cuff injury and repair.

This review delves into the intersection of two prevalent conditions, hyperlipidemia and rotator cuff injuries, both of which bear substantial healthcare burdens. Our investigation begins with an exploration of rotator cuff injuries, common musculoskeletal disorders that severely impair shoulder functionality and quality of life. These injuries are notably pervasive among sports enthusiasts and the older adult, with an incidence rate estimated at 5-10% in the general population. Despite their widespread occurrence and the diverse, multifactorial etiological factors, effective treatment strategies remain elusive. We then examine hyperlipidemia, a metabolic disorder affecting approximately 40% of the global adult population. Characterized by elevated levels of cholesterol and triglycerides, hyperlipidemia can precipitate severe cardiovascular complications and presents a significant socioeconomic burden. Although current management strategies encompass lifestyle modifications and pharmacological interventions, the condition remains a formidable health challenge. Central to this review is the exploration of a potential association between hyperlipidemia and rotator cuff injuries. We aim to synthesize the current understanding of hyperlipidemia's role in the pathophysiology of rotator cuff injuries, thereby offering fresh insights into their common etiological underpinnings, potential therapeutic targets, and drugs, such as Statins. The influence of other lipid-lowering therapeutics on tendon health is also considered, and further research into the molecular pathways and potential therapeutic benefits of these drugs is required. This pursuit aligns with broader efforts to enhance patient outcomes, minimize healthcare burdens, and contribute to the global understanding of these prevalent conditions.

Prognostic value and predictors of the alteration of the diffusing capacity of the lungs for carbon monoxide in systemic lupus erythematosus.

Systemic lupus erythematosus (SLE) is a systemic autoimmune disease characterized by heterogeneous manifestations and severity, with frequent lung involvement. Among pulmonary function tests (PFT), the measure of the diffusing capacity of the lungs for carbon monoxide (DLCO) is a noninvasive and sensitive tool assessing pulmonary microcirculation. Asymptomatic and isolated DLCO alteration has been frequently reported in SLE, but its clinical relevance has not been established. This retrospective study focused on 232 SLE patients fulfilling the 2019 EULAR/ACR classification criteria for SLE. Data were collected from the patient's medical record, including demographic, clinical, and immunological characteristics while DLCO was measured when performing PFT as part of routine patient follow-up. At the end of follow-up, DLCO alteration (<70% of predicted value) was measured at least once in 154 patients (66.4%), and was associated with a history of smoking as well as interstitial lung disease (ILD), but was also associated with renal and neurological involvement. History of smoking, detection of anti-nucleosome autoantibodies and clinical lymphadenopathy at diagnosis were independent predictors of DLCO alteration, while early cutaneous involvement with photosensitivity was a protective factor. DLCO alteration, at baseline or anytime during follow-up was predictive of admission in intensive care unit and/or of all-cause death, both mainly due to severe disease flares and premature cardiovascular complications. This study suggests a link between DLCO alteration and disease damage, potentially related to SLE vasculopathy, and prognostic value of DLCO on death or ICU admission in SLE.

Characteristics of arterial hypertension in patients after being in a combat zone in the Kharkiv region of Ukraine

Objective — to study the characteristics of arterial hypertension (AH) in patients (representatives of the civilian population) after their stay in the combat zone in the Kharkiv region of Ukraine.&#x0D; Materials and methods. The study involved 62 patients with 2—3 degree AH (29 men and 33 women), who were examined in the Department of Arterial Hypertension and Kidney Disease at L. T. Mala NIT NAMSU before the war and 4—5 months after its start. The interval between the baseline and re‑examination was 8—9 months. All examined patients during the war were in the combat zone in Kharkiv region of Ukraine. The mean patients’ age was 52.4±4.3 years. All patients underwent general clinical, laboratory and instrumental examinations. The degree, stage of hypertension and the presence of risk factors for cardiovascular disease (CVD), established CVD and kidney disease were assessed in accordance with recent recommendations. At baseline, before the war start, all patients were administered two‑ or three‑component antihypertensive and (in the presence of elevated levels of low‑density lipoprotein cholesterol (LDL‑C) lipid‑lowering therapy in accordance with the latest guidelines. All 62 patients (100%) during their dynamic observation before the war, reached target levels of «office» blood pressure (BP). The frequency of achieving target levels of LDL‑C was significantly lower and amounted to 57%.&#x0D; Results. In patients with hypertension (representatives of the civilian population), who were in the combat zone in the Kharkiv region of Ukraine and experienced chronic wartime stress, a significant increase in the frequency of severe and uncontrolled hypertension, its crisis course and resistant form was found. Prognostically unfavorable consequences of staying in the combat zone in patients with hypertension is a significant increase in the incidence of such risk factors for CVD as increased LDL‑C blood levels, prediabetes and insulin resistance, smoking and regular alcohol consumption. Staying in the combat zone leads to a significant increase in the incidence of coronary heart disease, heart rhythm disturbances and heart failure in patients with hypertension and contributes to the accelerated development of type 2 diabetes mellitus, as well as such severe cardiovascular and cerebrovascular complications as atrial fibrillation, acute myocardial infarction, transient ischemic attack and ischemic stroke&#x0D; Conclusions. The stay of patients with hypertension in the combat zone and the related chronic stress of wartime leads to a significant worsening of hypertension course and to the development of adverse metabolic disorders and cardiovascular and cerebrovascular complications. This justifies the need to establish dynamic monitoring for this category of patients and conduct long‑term combined therapy, taking into account the characteristics of the clinical course and the presence and severity of the disease complications.&#x0D;

Prognostic Significance of Carotid and Lower Extremity Artery Stenosis in Patients With High and Very High Cardiovascular Risk.

Aim To study prognostic significance of the degree of stenosis of carotid and lower-extremity arteries (LEA) in patients at high and very high risk of cardiovascular complications (CVC).Material and methods The study included men and women aged 40-67 years at high and very high risk of CVC. Duplex ultrasound scanning of carotid arteries and LEA was performed for all patients. Laboratory tests included measurements of glucose, glycated hemoglobin, total cholesterol, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglycerides, uric acid, creatinine with estimation of glomerular filtration rate (GFR) using the CKD-EPI Creatinine Equation formula, and high-sensitivity C-reactive protein (hsCRP). Composite endpoint was death from CVC, nonfatal myocardial infarction, nonfatal stroke, and coronary revascularization.Results The study included 214 patients from groups of high and very high risk of CVC. Median age of patients was 59.0 [53.2; 64.0] years. A very high risk was identified in 141 (65.8 %) patients and a high risk of CVC in 73 (34.1 %). Atherosclerotic plaques in at least one vascular bed were found in 191 (89.3 %) patients. Duration of the follow-up period was 32.0 [13.7; 49.1] months. Outcomes comprising the composite endpoint were observed in 36 (16.8 %) patients. Presence of carotid stenosis ≥35 % was not statistically significantly associated with the occurrence of outcomes comprising the composite endpoint (relative risk, RR: 1.22; 95 % confidence interval, CI: 0.56-2.66; p=0.607). In contrast, the presence of LEA stenosis ≥35 % was associated with a 2.51 times increased RR of CVC (95 % CI: 1.02-6.23; p=0.044).Conclusion In patients from the groups of high risk and very high risk of CVC, the presence of LEA stenosis ≥35 % predicted the development of severe CVC with a 69.4% sensitivity and a 61.8% specificity. The presence of LEA stenosis ≥35 %, but not of carotid arteries, was an independent predictor of severe CVC (RR, 2.51; 95 % CI: 1.02-6.23; p=0.044) after adjustments for sex, age, presence of arterial hypertension, diabetes mellitus, ischemic heart disease, obesity, smoking, LDL-C, GFR, and drug therapy.

Ocular, cardiovascular, and genetic characteristics and their associations in children with Marfan syndrome and related fibrillinopathies.

Congenital ectopia lentis (CEL) and heart abnormalities are common clinical symptoms in patients with Marfan syndrome (MFS) and related fibrillinopathies, which is caused by mutations in fibrillin-1 (FBN1) gene. This study aims to explore the ocular and cardiovascular characteristics and their association with genotype in children with MFS and related fibrillinopathies. Seventy-nine children diagnosed with CEL and with FBN1 mutations confirmed via whole-exome sequencing were included for genotypes and phenotypes analysis. The axial length (AL), corneal curvature, and refractive status were included for ocular phenotypes analysis. The cardiovascular examination was performed by echocardiography, and aortic root Z score was calculated to evaluate the severity of aortic dilatation. The heart disorders were classified as aortic root dilatation, valvular disorders, and others. Both the ocular and cardiac manifestations were collected for comprehensive analysis and compared among patients with different genotypes, including the mutation involving cysteine substitution or mutation in different regions. In CEL children with FBN1 mutations, 77.2% patients could be diagnosed as MFS. It was observed that children with mutations in exons 22-42 had significant higher aortic root Z score (P = 0.003) and higher incidence of cardiovascular disorders (P = 0.004). Additionally, children with cysteine substitution mutations had significant higher aortic root Z score (P = 0.011), and the aortic root Z score was positively associated with axial length (AL) in children under 6years old (P = 0.035). Those with long AL (≥ 26mm) had significant higher incidence of valve disorders (P = 0.023). In addition, nearly half the children with CEL (46.8%) were diagnosed with cardiovascular disease for the first time. CEL children with FBN1 mutations involving cysteine substitution or mutations in exons 22-42 or with long AL had higher risks of severe cardiovascular complications. Knowing the phenotype may help in anticipating severe cardiovascular disease in CEL patients.
