Aim. To study the rigidity of the vascular wall and microcirculation parameters in patients with uncontrolled (UCAH) and controlled arterial hypertension (CAH).Material and methods. 134 patients with essential hypertension were included, among them 88 (65.7%) patients with UCAH and 46 (34.3%) patients with CAH. Patients in both groups were similar by sex, age, duration of hypertension and some biochemical parameters. Patients had a study of the parameters of stiffness of the vascular wall, microcirculation parameters, as well as an evaluate of the plasma level of asymmetric dimethylarginine (ADMA).Results. Pulse wave velocity (PWV) did not differed between the UCAH and CAH, both in absolute values (1144 [1000-1290] vs 1138 [10281279] cm/sec; p=0.385) and in the frequency of exceeding the normal values (95% vs 92%; p=0.784). Microcirculation index (MI) in CAH was significantly higher than in the UCAH group: 30.55 [27.08-34.4] and 22.82 [18.62-26.05], respectively (p <0.05). ADMA plasma concentration was significantly higher 0.69 [0.62-0.81] μmol/l in UCAH, than in the CAH group 0.62 [0.58-0.70] µmol/l (p <0.05), that shows the presence of endothelial dysfunction. There were detected significant relation between MI and cognitive status.Conclusion. The results of our study indicate the presence of signs of endothelial dysfunction in patients with UCAH with changes in the stiffness of the vascular wall comparable with the CAH group. This may reflect the slower effect of antihypertensive therapy on the remodeling processes of large vessels in comparison with the microvasculature.

The main topic of the article is the assessment of the endothelial dysfunction and the rigidity of arterial wall in the small, medium and large vessels in young patients with short anamnesis of hypertension and with different variability of blood pressure (BP). In young patients even at the beginning of arterial hypertension (AH) the disturbance in rigidity of arterial walls in great and peripheral vessels occurs. The increased variability of BP in young patients with AH is an aggravating factor of the arterial rigidity disturbances. The assessment of arterial rigidity in young patients at the early stages of the disease can elicit the early signs of endothelial dysfunction

Mortality from diseases of the circulatory system is a challenge for the modern health care. Arterial hypertension (AH) mostly contributes to development of cardiovascular complications. It often proceeds against the background of metabolic disorders. Pathogenesis of hypertension is currently being considered a multifactorial disease. Pathogenesis of hypertension certainly has distinct features in presence of metabolic disorders,. Therefore, it is relevant to summarize current literature on the role of immunological disorders, endothelial dysfunction and hemostatic disorders in AH genesis during metabolic syndrome (MS). Most authors agree with existence of several mechanisms that determine relationships between AH and insulin resistance. Development of hypertension in MS patients with is a consequence of immunometabolic processes. Abdominal obesity is an important component of MS. It is associated with chronic inflammation of visceral adipose tissue, its excessive infiltration by immune cells, and increased production of adipokines and cytokines (TNFα, IL-6) with hypertension. AH is associated with a significant increase in T cells, that mediate endothelial dysfunction (ED) and provide a link between hypertension and subsequent atherosclerosis. T lymphocytes trigger a cascade of reactions. IL-17 is the end product of these events It is involved not only in increasing blood pressure, but also contributes to the development of vascular wall stiffness in АН patients. Thus, the relationship between several types of immune cells leads to inflammatory reactions, including those of vascular wall, initiating endothelial dysfunction. Chronic non-specific inflammation in MS, supported by the cytokine system, is a triggering mechanism for ED progression. Excessive production of endothelin-1 and inhibition of nitric oxide production are the classic markers of ED. Immune damage leads to imbalance in the production of vasoconstrictor and vasodilating substances, proliferative and antiproliferative factors in endothelium. It was shown that ED is an integral aspect of the insulin resistance syndrome in pathogenesis of arterial hypertension associated with metabolic disorders, and contributes to its worsening, increased vascular reactivity and further AH development. According to modern studies, it has been shown that excessive synthesis of pro-inflammatory cytokines introduces disturbances in the system of vascular hemostasis. When studying the effects of metabolic disorders upon hemostatic system, we may conclude that activation of fibrinolytic and plasma chains occurs in the same way for both men and women, with small gender characteristics of individual components. The rheological properties of the blood are also changed with developing MS. Systematization of the available literature data on the issue under study can serve as a basis for determining prognostic criteria of hypertension progression and risk of thrombotic complications.

Objective. Arterial hypertension (AH) is one of the most common and socially significant diseases worldwide. Despite years of experience gained in studying hypertension, the problems concerning selection of antihypertensive therapy with pleiotropic organ-protecting effects are still of current importance. Purpose - to assess therapeutic efficacy and pleiotropic organ-protective capability of third-generation calcium antagonist lercanidipine in patients with stage 2-3 hypertension. Materials and methods. Our study enrolled a total of ninety-two 31-to-84-year-old patients. Of these, 72 patients diagnosed as having stage 2 or 3 AH composed the Study Group and 20 apparently healthy subjects were included into the Control Group. At baseline and after 6 months, all patients of the Study Group underwent examinations consisting in measuring biochemical parameters [total cholesterol (TCH), triglycerides, low-density lipoprotein cholesterol (LDL CH), uric acid, urea, creatinine, glucose], 24-hour ambulatory BP monitoring, echocardiography in order to assess the dimensions and volume of the cardiac chambers, thickness of the left ventricular posterior wall (LVPW) and left-ventricular myocardium mass index (LVMMI), studying microalbuminuria (MAU), a known marker of endothelial dysfunction and early renal lesion; assessing the state of the vascular wall by the ankle-brachial index (ABI) and pulse pressure (PP). Antihypertensive therapy consisted in lercanidipine alone taken at a dose of 10-20 mg/day, failure to thereby achieve the target BP level was followed by additionally prescribing an angiotensin converting enzyme (ACE) inhibitor, enalapril, given at a dose of 5-20 mg twice daily. Results. All patients by the end of the study achieved the target level of AP (p≤0.05), also demonstrating significantly improved (p≤0.01) parameters of endothelial dysfunction and an early marker of renal damage (MAU), indices of elastic properties of the vascular wall ABI (p≤0.05) and PP (p=0.01). Significantly positive dynamics was observed for the following parameters: decreased creatinine concentration (p≤0.001), increased GFR (p≤0.001), decreased levels of TCH (p≤0.01) and LDL CH (p≤0.001). Conclusion. Lercanidipine therapy of patients with stage 2-3 AH proved highly efficient, well tolerated, metabolically neutral with pleiotropic organprotecting properties in the form of improved condition of the vascular wall, correction of endothelial dysfunction, nephroprotective action

Aim. To study the effect of multiagent chemotherapy on structural and functional vascular, electrophysiological parameters and cardiac hemodynamics in patients with stomach cancer.Material and methods. The study included 3 groups of 25 people: healthy volunteers, those with established cardiac disease (hypertension + coronary artery disease), gastric adenocarcinoma (fluoropyrimidine/platinum-based chemotherapy). Cancer patients before and after chemotherapy courses underwent non-invasive assessment of vascular wall and endothelial dysfunction (videocapillaroscopy, digital photoplethysmography), as well as electrocardiography and echocardiography. Healthy volunteers and cardiac patients were examined once.Results. In cancer patients, even before chemotherapy courses, endothelial dysfunction (ED) (occlusal index, 1,7 (1,4; 1,9), normal values >1,8) and structural vascular disorders (stiffness index, 8,9 m/s (7,7; 9,7), normal values <8 m/s; refractive index, 32,4% (27,5; 37,7), normal values <30%). All above-mentioned parameters significantly worsened after multiagent chemotherapy (progression of ED and vascular wall remodeling: occlusal index, 1,3 (1,2; 1,5) (p<0,0002); stiffness index, 10,3 m/s (9,5; 11,2) (p<0,0001); reflection index, 40,2% (35,5; 43,6) (p<0,001) Decrease in left ventricular ejection fraction and diastolic function was detected. The number of supraventricular and ventricular premature beats during chemotherapy increased 9 and 10 times, respectively (p<0,05).Conclusion. The study for the first time assessed the effect of multiagent chemotherapy on ED, vascular stiffness and cardiac hemodynamics in patients with gastric cancer. A significant aggravation of all endothelial function parameters after treatment has been proven, which requires further study in order to develop criteria for early cardiovascular toxicity.

Pulmonary arterial hypertension (PAH) is a rare multifactorial disease characterized by abnormal high blood pressure in the pulmonary artery, or increased pulmonary vascular resistance (PVR), caused by obstruction in the small arteries of the lung. Increased PVR is also thought to be caused by abnormal vascular remodeling, due to thickening of the pulmonary vascular wall resulting from significant hypertrophy of pulmonary arterial smooth-muscle cells (PASMCs) and increased proliferation/impaired apoptosis of pulmonary arterial endothelial cells (PAECs). Herein, we investigated the mechanisms and explored molecular pathways mediating the lung pathogenesis in two PAH rat models: Monocrotaline (MCT) and Sugen5416/Hypoxia (SuHx). We analyzed these disease models to determine where the vasculature shows the most severe PAH pathology and which model best recapitulates the human disease. We investigated the role vascular remodeling, hypoxia, cell proliferation, apoptosis, DNA damage and inflammation play in the pathogenesis of PAH. Neither model recapitulated all features of the human disease, however each model presented with some of the pathology seen in PAH patients.
