Abstract Introduction Features of changes in the vascular wall in women of the menopausal period are not sufficiently illuminated. Most of the studies evaluating the effect of menopausal hormonal therapy (MHT) on the structural and functional state of the vascular wall were limited to the time frame from several months to 1–3 years, which distinguishes them from our study. Purpose To evaluate structural and functional changes in the vascular wall in women of early postmenopausal period with prolonged use of low doses of MHT 1 mg of 17β-estradiol (E2) and 2 mg drospirenone (DRSP). Methods The study included 162 women in the early postmenopausal period with climacteric syndrome were divided into 2 groups: the main group of 84 women assigned MHT 1 mg E2 /2 mg DRSP, control group of 78 women who did not receive MHT. Duration of follow-up 5,2 (4,8; 5,7) years. Explored pulse wave velocity (PWV). Bbrachial blood pressure was measured non-invasively over the 24 h with an electronic, oscillometric, automated device (BPLab) with the assessment of 24-h central arterial pressure (CAP), aortic augmentation index (AIx), arterial stiffness index (ASI); ambulatory arterial stiffness index (AASI). Endothelium-dependent vasodilation (EDV) of the brachial artery was evaluated. Results In women of the main group PWV made up 7.19±1.7 m/s initial and 7.53±1.3 m/s to the end of the study (p>0.05); in the control group - 7,21±1.8 m/s and 7.95±1.9 m/s (p<0.001). In the women of the main group by the end of the study a decrease in the CAP was noted from 38.4±6.2 to 35.3±4.1 mm Hg. (p<0.001), in the women of the control group there were no changes of 41.4±9.6 and 40.9±9.8 mm Hg. (p<0.001 between women of both groups at the end of the study). In women of the control group, a significant increase in AIx was found from 31.0 (20.0; 35.0)% initially to 33.0 (29.0; 37.0)% by the end of the study (p<0.05) and no changes in women of the main group – 27.0 (20.0; 35.0)% and 28.0 (20.0; 33.0)%. Multidirectional changes ASI were revealed: a decrease in women of the main group from 132.0 (121.0; 142.0) to 127.0 (115.5; 137.0) cu and an increase from 133.0 (111.0; 155.0) to 148.0 (134.2; 171.0) cu in women of the control group (p<0.01 between women of both groups at the end of the study). By the end of the study, there was a decrease in AASI in women of the main group from 0.379 (0.320; 0.463) to 0.264 (0.203; 0.329) cu (p<0.001) and the absence of changes AASI value in women of the control group – 0.360 (0.283; 0.471) and 0.370 (0.310; 0.476) cu. In women of the main group, an increase in the brachial artery EDV was found from 8.6±7.4% initially to 11.1±6.8% by the end of the study (p<0.05) and no change in women in the control group −7.3±5.6% and 6.2±5.0%. Conclusion In women in early postmenopause with prolonged MHT of 1 mg E2/2 mg DRSP positive changes in the structural and functional state of the vascular wall were established.

Cardiovascular disease is one of the major causes of death throughout the world. Early detection of target organ damage is important for more successful prevention of cardiovascular diseases and improvement of patient outcomes. One of these target organs is the vascular wall, and its damage consists in loss of elastic properties and increase in stiffness. Many studies have shown that the increasing stiffness of the vascular wall is an independent predictor of cardiovascular risk. Objective: To evaluate parameters of the ambulatory arterial stiffness monitoring in patients with bronchial asthma. Materials and methods. The study enrolled 119 patients with asthma. The group of control included 30 practically healthy volunteers comparable by gender and age with the patients of the main group. Each patient underwent ambulatory blood pressure and arterial stiffness monitoring using BPLab MnSDP-2 device (Petr Telegin, Russia). Results: In patients with asthma higher values of augmentation index, arterial stiffness index and pulse wave velocity in the aorta in comparison with patients of the control group, as well as violation of the 24-hour profile of arterial stiffness were noted. Conclusion. Patients with asthma demonstrated significantly increased arterial stiffness in comparison with control group.

Objective. To assess the relationship between arterial stiffness parameters in hypertensive patients with and without atherosclerotic lesions.Design and methods. We included 127 subjects who were divided into 3 groups: patients with hypertension (HTN) without atherosclerosis (n = 42); patients with HTN and subclinical atherosclerosis (SА) (n = 52) and control group which consisted of individuals without HTN, SA, or coronary artery disease (n = 33). All groups matched by age and gender. All subjects underwent following examinations: ultrasonography of extracranial segments of carotid arteries, 24-hour blood pressure monitoring with the assessment of arterial stiffness parameters.Results. In subjects with HTN compared to controls, pulse wave velocity in aorta (PWVao) was significantly higher (11,3 ± 1,5; 12,3 ± 1,8 vs 10,4 ± 1,3 m/s; p < 0,05), as well as pulse pressure (PP) (46,4 ± 9,8; 45,6 ± 10,6 vs 39,9 ± 6,5 mmHg; p < 0,05), central pulse pressure (PPао) (35,5 ± 8,5; 34,9 ± 8,5 vs 30,9 ± 5,4 mmHg; p < 0,05), and arterial stiffness index (ASI) (141 (127, 159); 139 (128,5, 160,5) vs 126 (118, 138) mmHg; p < 0,05). In subjects with HTN and SA, PWVao was significantly higher compared to other groups (p < 0,05). No significant difference in augmentation index was found (–32,5 (–45, –12); –22 (–36, –12); –37 (–50, –17); p = 0,25). Аmbulatory arterial stiffness index was higher in controls (0,5 ± 0,2) compared to HTN group (0,4 ± 0,2; p = 0,05), while HTN and SA group did not differ significantly (0,5 ± 0,2; p = 0,3). PWVao above 11,15 m/s is associated with 4,3 (2,3–8,2) times higher rate of atherosclerosis plaque detection.Conclusions. In HTN patients, arterial stiffness is changed compared to healthy individuals. PWVao above 11,15 m/s is associated with 4,3 (2,3–8,2) times higher rate of atherosclerosis plaque detection. In patients with HTN and SA arterial stiffness is higher, which might have additional predictive value in risk stratification.

Abstract Background Arterial stiffness index (ASI) is closely related to coronary atherosclerosis. This study aims to explore whether ASI can predict coronary heart disease (CHD) and its severity. Methods In this study, a total of 726 patients with suspected CHD were recruited. Based on coronary angiography results, the subjects were assigned into three groups: the control group (without obvious coronary artery disease), single-vessel disease group, and multi-vessel disease group (the number of vessels diseased ≥ 2). At the same time, according to the results of angiography, myocardial enzyme spectrum, electrocardiogram, color Doppler echocardiography and clinical manifestations, these patients were divided into four groups: the control group, stable angina (SA) Group, unstable angina (UA) group, and acute myocardial infarction (AMI) group. We have compared whether there were differences in ASI and related baseline data between groups. Receiver operating curve (ROC) analysis was conducted to determine whether ASI could predict CHD and evaluate the severity. Results ASI was positively correlated with the number of diseased branches of coronary artery. The value of ASI was increased as the number of the diseased branches increased. The ASI value in the SA group was significantly higher compared with the control group. Furthermore, the ASI value in the UA and AMI groups was remarkably increased compared with the control and SA groups. The results of ROC analysis indicated that the sensitivity and specificity of ASI was 71.0% and 85.4% in diagnosing CHD, respectively. While ASI was used in predicting the severity of CHD, the sensitivity was 72.1% and specificity 57.9%. Conclusion ASI is of great value in the diagnosis of coronary heart disease and the prediction of its severity.

Abstract Aims Arterial hypertension, especially if not well-controlled, is one of the main risk factors predisposing to fatal cardiovascular diseases (CVDs). Moreover, the diagnosis of essential hypertension are increasing, therefore oxidative stress and chronic inflammation have also been identified as potential responsible for the development of endothelial damage. Among all the molecules, melatonin (MT) was chosen for its role as a powerful antioxidant and anti-inflammatory endogenous molecule. This trial aims to evaluate the early intervention at the base of the inflammatory and oxidative cascade (that results in the development of hypertension), to restore an oxidative balance leading to positive results even at the endothelial and vascular level using MT in addition to anti-hypertensive therapy. Methods The trial is randomized, prospective and monocentric control. We enrolled 23 patients with hypertension in absence of other cardiovascular or autoimmune diseases that could alter the oxidative background, from March 2018 to April 2019 (recruitment period). Patients were randomly assigned to two groups: ‘melatonin group’ (in which 16 patients add 1 mg/day of melatonin for a year, to their already settled therapy), and a ‘control’ group (consisting of 7 patients with no changes in their therapy). The average follow-up was 1 year from randomisation. Patients were evaluated before and after a period of 1 year through MT plasma concentration and serum antioxidant capacity (TAC) by specific quantitative ELISA method. Therefore endothelial dysfunction and arterial stiffness were evaluated too (using the non-invasive methods of EndoPAT and SphygmoCor). Results In ‘melatonin group’ arterial stiffness index statistically decreased (P 0.022), according to a significant increase in plasma melatonin values (P 0.003) and significant decrease in TAC levels (P 0.041) despite the ‘control’ group. The improvement of endothelial function was not significant (P 0.688). Blood pressure had not a significative improvement too (P 0.401). Conclusions Data obtained could confirm the hypothesis of activation of plasma antioxidant system against a situation of altered oxidative balance. In fact, it is possible to hypothesize a correlation between TAC and arterial stiffness that confirm the antioxidant role of MT. The combination between antihypertensive therapy and antioxidant supplementation is able to improve the vascular stiffness. Data obtained are still preliminary and present some limitations but we can think of proposing this trial as a future basis for other extensive and prolonged studies.

Background: Endothelial dysfunction is the first but reversible stage of atherosclerosis. A change in the functional state of the vascular endothelium, especially of a growing organism, can be the basis for the development of many diseases in adulthood. The study of the structural and functional state of peripheral vessels of adolescents with hypothalamic syndrome is extremely important for understanding of the mechanisms of formation of cardiometabolic risks.Aims: to compare the structural and functional state of the vascular wall of young men with hypothalamic syndrome and constitutionally exogenous obesity.Methods: During the study 360 males were examined (average age 21.27±2.44 years) and divided into 3 groups: group 1 -with hypothalamic syndrome (n=242); group 2 - with constitutionally exogenous obesity (n=98); control group - practically healthy individuals (n=20). Hypothalamic syndrome was verified in the presence of a symptom complex, including obesity and pink striae. Cross-group comparative analysis of results of clinical, laboratory and instrumental examination was carried out.Results: In the group of patients with hypothalamic syndrome, endothelium-dependent vasodilatation (9.44±1.26 versus 10.37±1.21%; p=0.001) and endothelium-independent vasodilatation (10.29±1.28 versus 11.29±1.14%; p=0.001) is worse than in the group of patients with constitutionally exogenous obesity, and the rate of endothelium-dependent vasodilatation is lower than the generally accepted norm. In addition, among patients with hypothalamic syndrome, the stiffness of the vascular wall is higher than among patients with constitutionally exogenous obesity (15.47±2.58 versus 13.24±3.84%; p=0.001). Statistically significant correlations were revealed between the structural and functional state of peripheral arteries and hemodynamic, hormonal, metabolic changes, and the level of C-reactive protein (p<0.05).Conclusions: The obtained data indicate a deterioration of endothelial function and an increase in vascular wall stiffness in obese patients, regardless of its etiology. The patients with hypothalamic syndrome have more pronounced structural and functional changes in the vascular wall are observed than patients with constitutionally exogenous obesity.
