The age is one of the main non-modified factors which reduces the elasticity of vessels and increases the appearance of atherosclerotic plaques. A number of studies have revealed that in some people, vascular changes occur at a younger age, while the presence of only classical risk factors does not explain the development of cardiovascular events in young people. This phenomenon is described as a syndrome of early, or accelerated, vascular aging (EVA). Aspects of this premature process include endothelial dysfunction, increased arterial stiffness, thickening of the intima-media complex and impaired dilatation of the central arteries, an increase of the reflected wave, hypertrophy of small vessels with a decrease in their lumen. Accelerated aging of the vascular wall increases the frequency of complications, therefore, recently "vascular age” is considered as an important predictor of individual risk of cardiovascular events. The review describes factors and mechanisms that trigger the process of EVA, genetic aspects of vascular damage and the biology of telomeres. Changes in hemodynamics and structural and functional properties of arteries during physiological and accelerated aging are presented. Currently, several indicators have been proposed that indicate arterial wall damaging and progression of vascular aging. The carotid-femoral pulse wave velocity is included in the list of indicators of subclinical target organs damage in ESH-ESC Guidelines for the management of arterial hypertension. The results of studies on the developing the new diagnostic markers for identifying individuals with "normal" or "early" ("accelerated") vascular aging are presented. Therapeutic strategies are aimed at decreasing the influence of factors that provoke EVA and include a non-pharmacological approach and medical intervention. The paper describes methods of therapeutic correction of the EVA syndrome.

The speckle tracking method allows one to quantify the temporal and spatial characteristics of myocardial contraction. Importantly, it does not depend on a scanning angle and allows one to record the movement of speckles in 2D mode in any direction, unlike tissue Doppler imaging. This examination is non-invasive, safe for patients, and economically more beneficial in comparison with other modern methods of assessing heart contractility: MRI and scintigraphy. Diagnostic thresholds are suggested for obtaining peak values of all types of global strains and strain rates by sampling a healthy group, which can reveal early signs of left ventricle contractility failure. Correlation relationships of deformation parameters between themselves and with left ventricular hemodynamic indices, as well as anthropometric parameters in healthy subjects highlight the features of heart contraction biomechanics. However, currently this method is scarcely studied because no generally accepted normal range of strain values exists. •It is necessary to have sufficient qualification and skills in dealing with the XStrain™ Esaote software to obtain optimal values ​​of myocardial deformation.•The study results expand the database of this software for users and determine the normal range of the left ventricular contractility parameters.•The revealed interrelationships of strain values ​​in healthy individuals are relevant for understanding how the contractility mechanisms are altered in patients, and open up the prospect of studying the heart's compensatory possibilities.

Aim. To assess the safety and efficacy of a single intravenous bolus of non-immunogenic staphylokinase compared with alteplase in patients with massive pulmonary embolism and hemodynamic instability. Non-immunogenic staphylokinase is a modified recombinant staphylokinase with low immunogenicity, high thrombolytic activity and fibrin selectivity.Material and methods. This multicenter, open-label, randomized, comparative clinical trial FORPE in two parallel groups was conducted in 23 clinical centers in Russia. A total of 310 patients aged 18 years and older with hemodynamic instability and computed tomography pulmonary angiography verified massive pulmonary embolism and right ventricular dysfunction were included. The patients were randomly assigned in either non-immunogenic staphylokinase (15 mg) or alteplase (100 mg) group. Both medicines were administered intravenously. An independent biostatistician created a randomization sequence using computer-generated random numbers. Randomization was performed using the envelopes. The study was open-label, and emergency unit staff, investigators, and patients were informed about the assigned drug. The primary efficacy endpoint was 7-day all-cause death after randomization. The non-inferiority margin was set at 10% for the difference in 7-day all-cause mortality after randomization between the compared groups. Non-inferiority was tested using the Welch t-test for the primary efficacy endpoint. Secondary efficacy endpoints were analyzed in both the intention-to-treat and per-protocol populations.Results. Of 348 patients screened between December 25, 2020, and July 31, 2023, 310 (89%) were included in the study. Of the total number, 155 (50%) patients were randomized to the non-immunogenic staphylokinase group and 155 (50%) to the alteplase group. In the non-immunogenic staphylokinase group, the primary efficacy endpoint, 7-day all-cause death, was 2% in the intent-to-treat population and 2% in the per-protocol population, whereas in the alteplase group it was 3% (odds ratio (OR) 0,75, 95% confidence interval (CI) 0,11-4,49; p=1,00) and 3% (OR 0,75, 95% CI 0,11-4,52; p=1,00), respectively. The difference in the primary efficacy endpoint was 0,6% (95% CI -2,8 to -4,0) in the intent-to-treat population and 0,6% (95% CI -2,9 to -4,2) in the per-protocol population. Thus, the lower limit of the 95% CI did not cross the non-inferiority margin (p<0,001). There were no cases of hemorrhagic stroke in the non-immunogenic staphylokinase group, whereas there were three cases (2%) of hemorrhagic stroke in the alteplase group (p=0,25). Serious adverse events were experienced by 11 patients (7%) in the non-immunogenic staphylokinase group compared with 12 patients (8%) in the alteplase group (p=1,00).Conclusion. Non-immunogenic staphylokinase is at least as effective as alteplase in the treatment of patients with massive pulmonary embolism with hemodynamic instability and has a higher safety profile. Future observational studies of non-immunogenic staphylokinase are needed to continue assessing its safety and efficacy. Given the high safety and efficacy of non-immunogenic staphylokinase, its use should be studied in patients with moderate-to-high risk pulmonary embolism.

Aim      To identify early predictors for progression of chronic heart failure (CHF) in patients with ST-segment elevation myocardial infarction (STEMI). Material and methods  The study included 113 patients with STEMI aged 52 (95 % confidence interval, 36 to 65) years. 24-h ECG monitoring was performed with assessment of ventricular late potentials, QT dispersion, heart rhythm turbulence (HRT), and heart rhythm variability (HRV); XStrain 2D echocardiograpy with determination of volumetric parameters, myocardial strain characteristics and velocities; and measurement of brain natriuretic peptide (BNP) concentrations. The endpoint was CHF progression during 48 weeks of follow-up, which was observed in 26 (23 %) patients. Based on the outcome, two groups were isolated, with CHF progression (Prg) (26(23%)) and with a relatively stable CHF postinfarction course (Stb) (87 (77 %)). Results At 12 weeks following MI, the Prg group showed increases in left ventricular (LV) end-diastolic dimension (EDD) (р<0.05) and end-diastolic and end-systolic volumes (EDV, ESV), (р<0.01), and EDV and ESV indexes (EDVi and ESVi, р<0.01). In this group, global longitudinal strain (GLS) was decreased at 24 weeks (р<0.05) and global radial strain (GRS) was decreased at 48 weeks (р=0.0003). In the Prg group, values of strain parameters (GLS, global circular strain (GCS), and GRS) were lower at all times. At 7-9 days, 24 weeks, and 48 weeks, the proportion of patients with pathological HRT was higher in the Prg group (38, 27, and 19 % for the Prg group vs 14 % (р=0.006); 3,4 % (р=0.001), and 2.3 % (р=0.002) for the Stb group, respectively). Only in the Stb group, increases in HRV were observed (SDNNi by 13 % (р=0.001), rMSSD by 24 % (р=0.0002), TotP by 49 % (р=0.00002), VLfP by 23 % (р=0.003), LfP by 22 % (р=0.008), and HfP by 77 % (р=0.002). At 7-9 days of MI, the Stb group had greater values of SDANN (р=0.013) and HfP (р=0.01). CHF progression correlated with abnormal values of turbulence onset (TO), disturbed HRT, increased BNP levels and LV ESD, and low values of GLS, GCS, and GRS. Combined assessment of HRT, LV ESD, and GLS at 7–9 days after STEMI allows identifying patients with high risk for CHF progression in the next 48 weeks. Conclusion      The markers for CHF progression after STEMI include abnormal TO values, disturbed HRT, increased BNP levels and LV ESD, and low values of GLS, GCS, and GRS. The multifactor logistic regression analysis revealed early predictors of CHF in the postinfarction period, including abnormal TO, increased LV ESD, and reduced GLS.

Introduction. Among the priorities of the strategic development of the health care system there is the telemedicine technologies implementation. Material and methods. The project was developed in the Penza State University. For the economic justification of the remote BP monitoring, the project technological scheme has been prepared, the market capacity has been assessed and competition has been analyzed, the business model and financial model of the project have been developed, and risks have been evaluated. Results. The project is deployed at the base and with the participation of the budget medical institution. The patient is provided with a tonometer with built-in GSM or blutooth module. After the patient’s BP has been measured, the data in an encrypted format is transmitted to the remote monitoring center and stored in the cloud base. For each patient, the doctor sets target and individual thresholds for blood pressure. Intermediate monitoring of BP is carried out by paramedical personnel who, in case of deviations from reference values, notify the attending physician. The patient receives feedback in the form of SMS-messages to his mobile phone: time for BP measuring, taking drugs and recommendations for the therapy correction. Payment is carried out according to the approved Mandatory Medical Insurance Fund tariff. Conclusion. The introduction of remote blood pressure monitoring will reduce the cost of providing medical care by reducing the number of hypertension complications, open up prospects for research and development of medical professionals. Fundamentally new conditions will arise for the study of chronopharmacology of antihypertensive drugs in patients with hypertension.
