ABSTRACT
BACKGROUND: According to the results of the ESSE-RF study, the frequency of obesity in the population reached 29.7%. Obesity is one of the main risk factors for the development of cardiovascular diseases. Features of the course of COVID-19 in patients with obesity is a very urgent problem. AIM: The aim of the study was a comparative investigation of clinical and laboratory-instrumental parameters in AH patients with or without obesity who had COVID-19 associated pneumonia, to identify the role of obesity as a potential predictor of post-COVID cardiovascular complications 3 months after discharge from the hospital. MATERIALS AND METHODS: Materials and methods. The study included 174 patients with COVID-19-associated pneumonia. Group 1 included 78 patients with AH without obesity, group 2 - 96 patients with AH and obesity. All patients were tested with a blood sample at the time of admission and 3 months after discharge from the hospital. We assessed parameters of general blood test, biochemistry, hemostasis, inflammation biomarkers - concentration of C-reactive protein (CRP), highly sensitive CRP (hs-CRP), homocysteine, IL-6, etc. All patients initially underwent computed tomography of the chest. In both groups, 24-hour blood pressure monitoring was performed using BPLaB device, according to the standard protocol;echocardiography using an expert class ultrasound diagnostic system Vivid S70. The study is registered with the Clinical Trials.gov database Identifier: NCT04501822. RESULT(S): Results. The biomarker that significantly distinguished the both groups of patients, as well as subgroups according to the degree of obesity was the concentration of maxCRP and hs-CRP, which was significantly higher in group 2. In addition, the registered maximum values of MPO, NT-proBNP, IL-1,6, TNA-alpha and NRL parameters in group 2 of patients with 2-3 degrees of obesity, may indicate the highest probability of developing delayed adverse cardiovascular complications in this group of patients. Mean systolic blood pressure, variability of systolic and diastolic blood pressure, and heart rate at night were significantly higher in AH patients with obesity. Numerous correlations of obesity with laboratory and instrumental parameters have been registered, which may indicate an increased likelihood of delayed unwanted cardiovascular complications in this particular group of patients. Multiple regression showed that obesity is an independent predictor of an increase in LDH, hs-CRP and right atrium. CONCLUSION(S): Dynamic control of the studied parameters in patients with AH and OB registered an increased concentration of CRP at the initial stage and 3 months after treatment, with a general trend towards a decrease in the increased initial structural parameters of ECHO CG. The logistic regression method showed that the presence of OB in patients with AH is an independent factor causing increased levels of immune inflammation (CRP), a marker of tissue destruction (LDH), and load on the right atrium.Copyright © Endocrinology Research Centre, 2022.

ABSTRACT
Aim. To investigate the relationship between echocardiographic parameters and laboratory immune inflammation signs in patients after coronavirus disease 2019 (COVID-19) pneumonia depending on the left ventricular (LV) involvement according to speckle tracking echocardiography (STE). Material and methods. The study included 216 patients (men, 51,1%, mean age, 50,1+/-11,1 years). The examination was carried out in patients 3 months after COVID-19 pneumonia. Patients were divided in 3 groups: group I (n=41) - diffuse decrease (>=4 segments the same LV level) of longitudinal strain (LS) according to STE;group II (n=67) - patients with regional decrease (LS reduction >=3 segments corresponding to systems of the anterior, circumflex or right coronary arteries);group III - patients without visual left ventricle involvement (n=108). Results. There were no significant differences in LV ejection fraction - 68,9+/-4,1% in group I, 68,5+/-4,4% in group II and 68,6+/-4,3 in group III (p=0,934). A decrease in the global longitudinal left ventricle strain was detected significantly more often in groups I and II compared with group III (-17,8+/-2,0, -18,5+/-2,0 and -20,8+/-1,8%, respectively;p<0,001). At the same time, LS depression of LV basal level (-14,9+/-1,5, -16,8+/-1,2% and -19,1+/-1,7%;p<0,001), as well as a decrease in LS of LV inferior-posterior segments in group with diffuse involvement was detected significantly more often than in groups II and III. In addition, we revealed a significant difference in interleukin-6 concentration - 3,1 [2,5;4,0], 3,1 [2,4;3,8] and 2,5 [3,8;1,7] pg/ml, (p=0,033), C-reactive protein - 4,0 [2,2;7,9], 5,7 [3,2;7,9] and 2,4 [1,1;4,7] mg/l, (p<0,001), tumor necrosis factor-alpha - 5,9+/-1,9, 6,2+/-1,9 and 5,2+/-2,0 pg/ml, (p=0,004) and ferritin - 130,7 [56,5;220,0], 92,2 [26,0;129,4] and 51,0 [23,2;158,9] microg/l, respectively (p=0,025). Conclusion. A relationship was found between diffuse and regional left ventricular involvement according to STE and signs of immune inflammation in patients 3 months after COVID-19 pneumonia.Copyright © 2023 Vserossiiskoe Obshchestvo Kardiologov.

ABSTRACT
The aim. To study peculiarities and association of psychological and laboratory indicators in patients with cardiovascular diseases (CVD) who underwent COVID-19 to clarify the factors affecting the possibility of developing delayed psychological and cardiovascular adverse events. Methods. The study enrolled 350 patients with COVID-19. Group 1 consisted of 92 patients without CVD, Group 2 - of 258 patients with CVD. Indicators of laboratory and psychological parameters were assessed according to the data of psychological questionnaire using GAD-7 (General Anxiety Disorder-7), PHQ-9 (Patient Health Questionnaire-9), PSS (Perceived Stress Scale) screening scales and SF-36. Parameters of complete blood count and biochemical blood tests were measured during hospitalization and three months after discharge from the monohospital. Results. After three months, in the general group of patients, signs of anxiety and depression were detected in more than 30 % of the examined patients, signs of stress - in 10.4 %. In the group with CVD, psycho-emotional disorders were identified in 1/4 of the patients, and severe stress - in 8 % of those included in the study. In addition, it was registered that the indicators of erythrocyte sedimentation rate, fibrinogen, high-sensitivity C-reactive protein (CRP), homocysteine andIL-6remained at a higher level in the second group. Correlation analysis showedthatthe psychologicalcomponentofhealthis interconnectedwiththe levelofneutrophils (p= 0.044)andfibrinogen (p= 0.050);the physical component of health is correlated with the level of erythrocytes (p = 0.030), hemoglobin (p = 0.015), CRP (p = 0.002), creatine phosphokinase (p = 0.036) and glucose (p = 0.017). Regression analysis revealed that in patients with CVD three months after hospitalization, an increased glucose index contributes to deterioration, andincreasedhematocritandmean hemoglobin concentration improve the quality of life of patients. Conclusion. Laboratory markers that maintain the duration of a prolonged vascular reaction, violation of the rheological and metabolic properties of blood, determine the nature of the development of both psychological and cardiovascular complications. © 2023 Voprosy Literatury.

ABSTRACT
Background. Studying the impact of complicated course of new coronavirus infection on the cardiovascular system in the long term after patient discharge from hospital is of high significance. Purpose. To compare the clinical and echocardiographic parameters of persons with history of verified COVID-19 pneumonia one year after discharge from hospital depending on the value of left ventricular (LV) global longitudinal strain (GLS). Material and Methods. A total of 116 patients (50.4% men) aged 49.0 ± 14.4 years (from 19 to 84 years) with history of verified COVID-19 pneumonia were examined one year ± three weeks after discharge. The parameters of left ventricular global and segmental longitudinal strain were studied in 80 patients with optimal quality of echocardiographic visualization. Patients were divided into groups depending on the LV GLS value: group 1 included 35 patients with normal LV GLS (<-20%);group 2 comprised 45 patients with impaired LV GLS (≥-20%). The groups did not differ in age (p = 0.145), severity of lung injury during hospitalization (p = 0.691), duration of hospitalization (p = 0.626), and frequency of stay in the intensive care unit (p = 0.420). Results. Abnormal values of LV GLS one year after discharge were found in 57.5% of patients with optimal visualization quality while the LV ejection fraction (EF) was normal in all patients. The majority of patients in group 2 were men (71.1% vs 28.6%, p < 0.001). A combination of coronary artery disease (CAD) and hypertension (AH) was more often diagnosed in this group (22% vs 6%, p = 0.040). The values of LV EF did not differ between the groups. The values of LV GLS were significantly worse in patients of group 2 (-17.6 ± 1.9% vs -21.8 ± 1.2%, p < 0.001). Moreover, the parameters of diastolic function including the left atrial emptying volume index (1.3 ± 0.3 mL/m2 vs 1.4 ± 0.3 mL/m2, р = 0.052) and velocity of the lateral part of the mitral valve fibrous ring e' (10.8 ± 4.4 cm/s vs 12.8 ± 4.0 cm/s, p = 0.045) were also lower in this group. Conclusions. The LV GLS was impaired in 57.5% patients with normal LV EF one year after COVID-19 pneumonia. In the group with impaired LV GLS, men predominated;coronary artery disease was more often detected in combination with AH;and parameters of LV diastolic function were worse compared with the corresponding parameters in the group of patients with normal LV GLS. © 2022 Tomsk State University.

ABSTRACT
Aim. To study the changes of morphological and functional right ventricular (RV) parameters depending on the severity of coronavirus infection 2019 (COVID-19) pneumonia over long-term follow-up. Material and methods. A total of 200 patients (men, 51,5%, mean age, 51,4+/-10,9 years) were examined at 2 control visits (3, 12 months after receiving two negative polymerase chain reaction tests). Patients were divided into following groups: group I (n=94) - lung tissue involvement >=50% according to inhospital chest computed tomography (chest CT), group II (n=106) - lung tissue involvement <50% according to chest CT. Results. The groups were comparable in key clinical and functional parameters 3 months after COVID-19 pneumonia. Speckle tracking echocardiography (STE) revealed a significant increase in following global longitudinal strain (LS) parameters: RV free wall endocardial LS (-22,7+/-3,2% and-24,3+/-3,8% in group I, p<0,001;-23,2+/-3,5% and-24,5+/-3,4% in group II, p<0,001), and RV endocardial LS (-21,0+/-3,1% and-22,5+/-3,7% in group I, p<0,001,-21,5+/-3,2% and-22,6+/-3,3% in group II, p=0,001). Significant increase of segmental endocardial LS was revealed in group I in the basal segments of RV free wall (-26,2+/-5,1% and-28,1+/-5,1%, p=0,004) and interventricular septum (IVS) (-16,2 [13,9;19,5]% and-17,5 [14,6;21,4]%, p=0,024), IVS middle segment (-20,3+/-4,1% and-21,5+/-4,8%, p=0,030), as well as in group II in the apical segments of RV free wall (-21,9+/-6,7% and-24,4+/-5,2%, p=0,001) and IVS (-23,7+/-4,7% and-24,9+/-4,8%, p=0,014). Conclusion. Recovery of RV function during a 12-month follow-up period in patients with both severe and moderate/mild lung involvement in COVID-19 was detected using the STE method.Copyright © 2023, Silicea-Poligraf.

ABSTRACT
Coronavirus disease 2019 (COVID-19) affects the function of all organs and systems. Today, studying the effect of COVID-19 on cardiovascular system, including on echocardiographic characteristics, is relevant. Aim. To study the prevalence of symptoms, cardiovascular disease and changes in echocardiographic data in persons after documented COVID-19 pneumonia 3 months after discharge from the hospital. Material and methods. The study included 106 patients after documented COVID-19 pneumonia. The patients underwent a comprehensive examination during hospitalization and 3 months+/-2 weeks after discharge from the hospital. The mean age of participants was 47+/-16 years (19-84 years);49% of subjects were women. Results. Three months after hospital discharge, the symptoms persisted in 86% of examined patients. There were significant echocardiographic changes as follows: a decrease in LV end-diastolic, end-systolic and stroke volume (113,8+/-26,8 ml vs 93,5+/-29,4 ml;37,7+/-13,0 ml vs 31,3+/-14,2 ml;77,2+/-17,8 ml vs 62,2+/-18,7 ml, respectively, p<0,001 for all). The right ventricular anteroposterior dimension and the pulmonary trunk diameter decreased over time (26,0 [24,0-29,3] mm vs 25,0 [23,0-27,0] mm, p=0,004;21,7+/-3,6 mm vs 18,7+/-2,5 mm, p<0,001), the same as the pulmonary artery systolic pressure, estimated by tricuspid regurgitation gradient (28,0 [25,0-32,25] mm Hg vs 21,5 [17,0-25,0] mm Hg). The right atrial volume (42,0 [37,0-50,0] ml vs 31,0 [22,0-36,5] ml, p<0,001) and maximum width (36,1+/-4,6 mm vs 34,5+/-6,5 mm, p=0,023) decreased, while the right atrial maximum length increased (46,7+/-6,8 mm vs 48,6+/-7,1 mm, p=0,021). Conclusion. In survivors of COVID-19 pneumonia three months after hospital discharge, complaints persisted in 86% of cases. Cardiovascular diseases were detected in 52% of participants, including hypertension in 48,1% and coronary artery disease in 15,1%. Compared with in-hospital data, the echocardiographic characteristics improved, which was expressed mainly in a decrease in right heart load. Copyright © 2021, Silicea-Poligraf. All rights reserved.
ABSTRACT
Funding Acknowledgements Type of funding sources: None. Background COVID-19 affects firstly the respiratory system, however the cardiovascular system is also damaged. To study the long-term effect of COVID-19 pneumonia on cardiovascular system, in particular on echocardiography (EchoCG) parameters of right heart is important for patients rehabilitation. Purpose To compare EchoCG parameters of right heart in patients with proven COVID-19 pneumonia 3 months and one year after discharge. Methods A total of 116 patients with confirmed COVID-19 pneumonia were included from April 2020 to July 2021. All patients underwent clinical examination including transthoracic EchoCG 3 months ±2 weeks and one year ±3 weeks after discharge. Mean age of patients was 49.0 ± 14.4 years (19-84 years), females were 49.6%. During hospitalization, chest computed tomography (CT) detected mild lesions in 31.3%, moderate lesions in 33.3%, severe lesions in 29.3% and critical lesions in 6.1%. Results The rate of resolution of lung abnormalities according to CT was 55.9%. Mean body mass index was 28.7 ± 5.8 kg/m2 3 months after discharge, and it significantly increased to one year after discharge – 29.4 ± 6.1 kg/m2 (p < 0,001). The mean anteroposterior right ventricular (RV) diameter index decreased over the observation period (13.5 ± 1.9 vs 13.0 ± 1.5 mm/m2, p <0.001), as well as the indices of end-diastolic and end-systolic RV area (8.0 ± 1.8 vs 7.5 ± 1.5 cm2/m2 and 3.8 ± 1.1 vs 3.3 ± 0.8 cm2/m2, respectively, both p < 0.001). The basal RV diameter increased (30.4 ± 5.4 versus 31.1 ± 4.1 mm, p = 0.045), the mid-cavitary RV diameter did not change (25.8 ± 5.4 and 25.8 ± 4.2 mm, p = 0.852), and the base to apex RV length decreased (69.5 ± 8.8 vs 63.9 ± 8.3 mm, p < 0.001). Basal and mid RV sphericity indices (RVSI) increased (0.44 ± 0.07 vs 0.49 ± 0.07 and 0.37 ± 0.07 vs 0.41 ± 0.07, respectively, both p < 0.001). The systolic excursion of the fibrous ring of the tricuspid valve (TAPSE) (22.7 ± 3.2 and 22.8 ± 2.3 mm, p = 0.637) and the tricuspid annular peak systolic velocity S" did not change significantly (10.4 ± 2.6 and 10,1 ± 3.0 cm/s, p = 0.289). The fraction of change in the RV area (FAC RV) increased (52.6 ± 8.2 vs 55.0 ± 8.9%, p = 0.019). The right ventricular outflow tract velocity time integral (RVOT VTI) decreased (18.1 ± 4.0 vs 16.4 ± 3.7 cm, p < 0.001). There were tendencies to increase in the systolic pulmonary artery pressure (PAPs) (22.5 ± 7.1 and 23.3 ± 6.3 mm Hg, p = 0.076) and to increase of the right atrium (RA) long axis dimension (48.7 ± 6.5 vs 49.5 ± 6.3 mm, p = 0.074). Conclusions Compared to three months after discharge, in patients one year after COVID-19 pneumonia EchoCG showed the anteroposterior RV diameter and the end-diastolic RV area decreased, the FAC RV increased. However, increase of the basal and mid RVSI, decrease in the RVOT VTI and tendencies to increase of the PAPs and the RA long axis dimension was observed. A subgroup analysis is planned depending on the severity of lung damage during hospitalization.
ABSTRACT
Funding Acknowledgements Type of funding sources: None. Background The long-term effect of a complicated course of COVID-19 on echocardiography (EchoCG) parameters, in particular on left heart, has not been sufficiently studied. Purpose To compare EchoCG parameters of left heart in patients with proven COVID-19 pneumonia 3 months and one year after discharge. Methods The patients were identified according to the data of the medical information system of the monohospital from April 2020 to July 2021 within the framework of "One-year Cardiac Follow-up of COVID-19 Pneumonia". A total of 116 men and women were included, mean age 49 ± 14.4 years, females 49.6%. During hospitalization, chest computed tomography detected mild lesions in 31.3%, moderate lesions in 33.3%, severe lesions in 29.3% and critical lesions in 6.1%. All patients underwent clinical examination including transthoracic EchoCG with 3 months ± 2 weeks and one year ± 3 weeks after discharge. All images were digitally stored and analyzed using off-line post processing with TomTec (Philips). The LV global and segmental longitudinal strain (LS) were studied in 100 individuals with satisfactory visualization quality 3 month after discharge and in 81 individuals one year after discharge. Results During the observation, the average body mass index of the subjects increased (28.7 ± 5.8 kg/m2 3 months after discharge vs 29.4 ± 6.1% one year after discharge, p < 0.001), as well as the rate of cardiovascular diseases (67% 3 months after discharge versus 79% one year after discharge, p = 0.008). Significant dynamics of mean left heart EchoCG parameters were observed. The mean index of left atrium (LA) maximal volume decreased (26.0 ± 7.2 vs 25.3 ± 7.4, p = 0.015), index of LA minimal volume increased (9.9 ± 5.4 vs 10.8 ± 5.6 ml/m2, p = 0.011). Left ventricular (LV) end-diastolic, end-systolic and stroke volume indexes decreased (49.3 ± 11.3 vs 46.9 ± 9.9 ml/m2, p = 0.008;16.0 ± 5.6 vs 14.4 ± 4.1 ml/m2, p = 0.001;36.7 ± 12.8 vs 30.8 ± 8.1 ml/m2, p < 0,001, respectively). The LV myocardial mass index increased (70.0 [60.8–84.0] vs 75.4 [68.2–84.9] g/m², p = 0.024). LV ejection fraction increased (68.1 ± 5.3 vs 69.7 ± 4.6%, p = 0.013). The LV global LS (-20.3 ± 2.2 vs -19.4 ± 2.7%, p = 0.001) and the LV segmental LS worsened: in mid segments (antero-septal -21.1 ± 3.3 vs -20.4 ± 4.1%, p = 0.039;inferior -21.0 ± 2.7 vs -20.0 ± 2.9%, p = 0.039;lateral -18.4 ± 3.7 vs -17.6 ± 4.4%, p = 0.021), and in apical segments (anterior -22.3 ± 5.0 vs -20.8 ± 5.2%, p = 0.006;inferior -24.6 ± 4.9 vs -22.7 ± 4.6, p = 0.003;lateral -22.7 ± 4.5 vs -20.4 ± 4.8%, p < 0.001;septal -25.3 ± 4.2 vs -23.1 ± 4,4%, p < 0.001;apical -23.7 ± 4.1 vs -21.8 ± 4.1%, p < 0.001). Conclusions Compared to 3 month after discharge, in patients one year after COVID-19 pneumonia the LA maximal volume, LV end-diastolic, end-systolic and stroke volumes decrease, and the LV ejection fraction increased. However, the LA minimal volume increased, and the LV global and segmental LS of the apical and mid LV segments worsened.
ABSTRACT
Funding Acknowledgements Type of funding sources: None. Background Coronavirus disease 2019 (COVID-19) is caused by the novel severe acute respiratory syndrome coronavirus 2. Pulmonary vascular resistance (PVR) is an important hemodynamic variable used in the management of patients with cardiovascular and pulmonary pathology. Doppler echocardiography has significantly impacted clinical medicine by its ability to assess intracardiac hemodynamics noninvasively. It seems actual to reveal the relationship between right heart function and lungs involvement in COVID-19. Purpose To assess the relationship right ventricular (RV) echocardiographic structural and functional parameters with indicators of increased pulmonary vascular resistance (PVR) in patients 3 months after COVID-19 pneumonia. Methods 96 patients (mean age 47.6 ± 15.2 years) were examined during hospitalization and at control visit (3 months follow-up). The equation tricuspid regurgitation velocity / time-velocity integral of the RV outflow tract X 10 + 0.16 has been used to determine PVR. Patients were divided into 2 groups: I group (n = 31) – patients with increase of PVR ≥1.5 Wood unit (WU) and II group (n = 65) – with decrease of PVR <1.5 WU. Results At baseline groups did not differ in main clinical characteristics, including severity of lung involvement in COVID-19 by computed tomography (32.7 ± 22.1% vs 36.5 ± 20.4%, р=0.418). Linear, planimetric and volumetric parameters did not differ significantly between groups. At the control visit RV free wall (FW) global endocardial longitudinal strain (LS) (-19.3 [-17.9;-25.8] % in group I vs -23.4 [-19.8;-27.8] % in group II, p = 0.048), tricuspid annular plane systolic excursion (21.7 ± 3.8 mm vs 23.3 ± 3.4 mm, p = 0.040) and RV maximum systolic velocity assessed by tissue Doppler imaging (12.3 ± 2.4 cm/s vs 13.4 ± 2.0 cm/s, p = 0.024) were significantly reduced in group I, systolic pulmonary artery pressure (sPAP) according to Otto C. (32.0 [26,0;35.0] mm Hg vs 23.0 [20.0;28.0] mm Hg, p <0.001) was significantly increased in group I. According to logistic regression only endocardial RV FW LS (OR 0.859;95% CI 0.746 - 0.989;p = 0.034) and sPAP (OR 1.248;95% CI 1.108 - 1405;p <0.001) had an independent relationship with increase of PVR. According to Spearman correlation analysis the moderate relationship was found between PVR and mean pulmonary artery pressure according to Mahan G. (r = 0.516, p = 0.003), PVR and RV–pulmonary artery coupling (r=-0.509, p = 0.007) in group I at the control visit. Conclusion Hidden RV systolic dysfunction defined as decreased endocardial RV FW LS to -19.3% is associated with increased PVR ≥1.5 WU in patients 3 months after COVID-19 pneumonia. Figure.

ABSTRACT
Aim To study the relationship of echocardiographic right ventricular (RV) structural and functional parameters and indexes of pulmonary vascular resistance (PVR) in patients 3 months after COVID-19 pneumonia.Material and methods This cross-sectional, observational study included 96 patients aged 46.7±15.2 years. The inclusion criteria were documented diagnosis of COVID-19-associated pneumonia and patient's willing to participate in the observation. Patients were examined upon hospitalization and during the control visit (at 3 months after discharge from the hospital). Images and video loops were processed, including the assessment of myocardial longitudinal strain (LS) by speckle tracking, according to the effective guidelines. The equation [tricuspid regurgitation velocity/ time-velocity integral of the RV outflow tract × 10 + 0.16] was used to determine PRV. Patients were divided into group 1 (n=31) with increased PRV ≥1.5 Wood units and group 2 (n=65) with PRV <1.5 Wood units.Results At baseline, groups did not differ in main clinical functional characteristics, including severity of lung damage by computed tomography (32.7±22.1 and 36.5±20.4â%, respectively. Ñ=0.418). Echocardiographic linear, planimetric and volumetric parameters did not significantly differ between the groups. In group 1 at the control visit, endocardial LS of the RV free wall (FW) (-19.3 [-17.9; -25.8] %) was significantly lower (Ñ=0.048) than in group 2 (-23.4 [-19.8; -27.8] %), and systolic pulmonary artery pressure (sPAP) according to C. Otto (32.0 [26.0; 35.0] mm Hg and 23.0 [20.0; 28.0]âmm Hg) was significantly higher than in group 2 (Ñ<0.001). According to the logistic regression, only endocardial RV FW LS (odds ratio, OR, 0.859; 95â% confidence interval, CI, 0.746-0.989; Ñ=0.034) and sPAP (OR, 1.248; 95â% CI, 1.108-1405; Ñ<0.001) were independently related with the increase in PVR. Spearman correlation analysis detected a moderate relationship between PVR and mean PAP according to G. Mahan (r=0.516; p=0.003) and between PVR and the index of right heart chamber functional coupling with the PA system (r=-0.509; p=0.007) in group 1 at the control visit.Conclusion In patients 3 months after COVID-19 pneumonia, hidden RV systolic dysfunction defined as depressed endocardial RV FW LS to -19.3% is associated with increased PVR ≥1.5 Wood units.

The study of the characteristics and dynamics of laboratory biomarkers in patients with cardiovascular diseases (CVD) undergoing COVID-19-associated pneumonia may be of great clinical importance. The study included 116 patients who underwent COVID-19-associated pneumonia. The patients were divided into 2 groups. The first group included 49 patients without CVD, the second group - 67 patients with CVD. A blood sample was performed in all patients at the time of hospitalization and 3 months after discharge from the hospital. The parameters of general blood count, biochemistry, hemostasis, and biomarkers of inflammation were assessed - concentration of C-reactive protein (CRP), highly sensitive CRP (hs-CRP), homocysteine and IL-6. All patients initially underwent computed tomography of the chest organs. We found that ESR, WBC (leukocytes), NLR (neutrophils/lymphocytes ratio), fibrinogen, LDH (lactate dehydrogenase), LYM/CRP ratio (lymphocytes/CRP) were parameters that significantly distinguished patients in the 1st and 2nd groups. Three months after discharge from the hospital in patients of both groups the increased indicators approached the reference values, however, some parameters such as CRP, ESR, WBC, fibrinogen remained at a higher level in group 2 compared to group 1. Correlation analysis revealed the relationship between parameters of inflammation and hemostasis in the 2nd group of patients, which confirms the presence of latent vascular inflammatory potential in this group. It was revealed that such indicators as lymphocytes, neutrophils, APTT and LDH were associated with the initial volume of lung lesion more than 50%. Increase of these parameters by 1 unit contributes to increase in the volume of lung tissue damage by 6.5%, 6.4%, 11%, and 0.6%, respectively. Thus, dynamic control of laboratory parameters has prognostic value in assessing the nature of the course of COVID-19 associated pneumonia in patients with CVD and developing an algorithm for personalized monitoring of patients in the post-COVID period with the aim of timely correction of therapy to prevent unwanted vascular complications.

Aim To study changes in clinical and echocardiographic parameters in patients after documented COVID-19 pneumonia at 3 months and one year following discharge from the hospital. Material and methods The study included 116 patients who have had documented COVID-19 pneumonia. Patients underwent a comprehensive clinical evaluation at 3 months ± 2 weeks (visit 1) and at one year ± 3 weeks after discharge from the hospital (visit 2). Mean age of the patients was 49.0±14.4 years (from 19 to 84 years); 49.6â% were women. Parameters of global and segmentary longitudinal left ventricular (LV) myocardial strain were studied with the optimal quality of visualization during visit 1 in 99 patients and during visit 2 in 80 patients.Results During the follow-up period, the incidence rate of cardiovascular diseases (CVD) increased primarily due to development of arterial hypertension (AH) (58.6 vs. 64.7â%, Ñ=0.039) and chronic heart failure (CHF) (35.3% vs. 40.5â%, Ñ=0.031). Echocardiography (EchoCG) showed decreases in values of end-diastolic dimension and volume, LV end-systolic and stroke volumes (25.1±2.6 vs. 24.5±2.2âmmâ/m2, p<0.001; 49.3±11.3 vs. 46.9±9.9âmlâ/m2, p=0.008; 16.0±5.6 vs. 14.4±4.1âmlâ/m2, p=0.001; 36.7±12.8 vs. 30.8±8.1âmlâ/m2, p<0.001, respectively). LV external short-axis area (37.1 [36.6-42.0] vs. 38.7 [35.2-43.1]âcm2, Ñ=0.001) and LV myocardial mass index calculated with the area-length formula (70.0 [60.8-84.0] vs. 75.4 [68.2-84.9]âgâ/m², Ñ=0.024) increased. LV early diastolic filling velocity (76.7±17.9 vs. 72.3±16.0âcmâ/sec, Ñ=0.001) and lateral and septal early diastolic mitral annular velocities decreased (12,10±3,9 vs. 11.5±4.1âcmâ/sec, Ñ=0.004 and 9.9±3.3 vs. 8.6±3.0âcmâ/sec, Ñ<0.001, respectively). The following parameters of LV global longitudinal (-20.3±2.2 vs. -19.4±2.7â%, Ñ=0.001) and segmental strain were impaired: apical segments (anterior, from -22.3±5.0 to -20.8±5.2â%, Ñ=0.006; inferior, from -24.6±4.9 to -22.7±4.6, Ñ=0.003; lateral, from -22.7±4.5 to -20.4±4.8â%, Ñ<0.001; septal, from -25.3±4.2 to -23.1±4.4â%, Ñ<0.001; apical, from -23.7±4.1 to -21.8±4.1â%, Ñ<0.001), mid-cavity (anteroseptal, from -21.1±3.3 to -20.4±4.1â%, Ñ=0.039; inferior, from -21.0±2.7 to -20.0±2.9â%, Ñ=0.039; lateral, from -18.4±3.7 to -17.6±4.4â%, Ñ=0.021). RV basal and mid-cavity sphericity indexes increased (0.44±0.07 vs. 0.49±0.07 and 0.37±0.07 vs. 0.41±0.07, respectively, Ñ<0.001 for both). A tendency for increased calculated pulmonary arterial systolic pressure (22.5±7.1 and 23.3±6.3âmm Hg, Ñ=0.076) was observed. Right ventricular outflow tract velocity integral decreased (18.1±4.0 vs. 16.4±3.7âcm, Ñ<0.001).Conclusion Patients after COVID-19 pneumonia one year after discharge from the hospital, compared to the follow-up data 3 months after the discharge, had an increased incidence of CVD, primarily due to the development of AH and CHF. EchoCG revealed changes in ventricular geometry associated with impairment of LV diastolic and systolic function evident as decreases in LV global longitudinal strain and LV myocardial apical and partially mid-cavity strain.

The study of the features and dynamics of the erythrocyte parameters of general blood analysis in patients with cardiovascular diseases who underwent SARS-CoV-2 associated pneumonia is of great practical importance. That was a prospective study. The study included 106 patients with SARS-CoV-2-associated pneumonia. All patients were divided into 2 groups. The first group included 51 patients without CVD, the second group included 55 patients with CVD .Patients in both groups underwent laboratory examination of blood samples at the time of hospitalization and 3 months after discharge from the hospital. Parameters of the erythroid series of the general blood test were assessed. Among inflammatory biomarkers, we examined the concentration of C-reactive protein (CRP), high-sensitivity CRP (hs-CRP) and homocysteine. Initially all patients underwent computed tomography of the chest organs. Revealed what indicators of the erythroid series in the groups of patients with and without CVD had significant differences in a number of parameters: ESR; RDW-SD and RDW-CV with significant excess of parameters in group 2. Three months after discharge from the hospital, patients in both groups had a significant increase in HCT, MCV, MCH. There was detected decrease in both groups in MCHC, RDW-CV (p<0.001 for all parameters), ESR level in group 2.At baseline, CRP exceeded reference values in both groups of patients, reaching maximum values in group 2. After 3 months CRP decreased significantly only in group 1. Increased CRP was associated with elevated hs-CRP in 3 months after discharge and elevated homocysteine levels in both groups, indicating the persistence of prolonged inflammatory vascular reaction in patients after SARS-CoV-2 associated pneumonia, more pronounced in group 2 patients. RDW-CV over 13.6 and lymphocytes / CRP less than 0.6 increase the likelihood of having lung tissue damage over 50% by 9.3 and 5.9 times, respectively. Thus, the data obtained confirm that RDW-CV, the coefficient of variation of erythrocyte distribution width, associated with the parameters of inflammatory response and the lymphocytes / CRP is lung volume marker and of COVID-19 severity. Careful consideration of already known laboratory parameters allows us to expand the number of indicators influencing the risk of COVID-19 complications and enable an earlier response to a difficult situation.

Background: COVID-19 is the highly contagious infectious disease, which affects different organs and systems. Anxiety and depression symptoms, that are common results of severe diseases, used to make recovery more difficult. Purpose: To study the prevalence of cardiovascular diseases, signs of anxiety, depression, stress, and their relationship in patients with proven COVID-19 pneumonia 3 months after discharge depending of gender. Methods: The study was carried out within “One-year Cardiac Follow-up of COVID-19 Pneumonia”. 103 patients (mean age 46.6±15.8 years) were divided into 2 groups: 52 men (50.9%) and 51 women. Anxiety and depression symptoms were measured by GAD-7 and PHQ-9, respectively. PSS-10 was used to measure stress symptoms. The minimum value of anxiety and depression was a total value of 5 points. Results: 48.5% of patients had cardiovascular diseases, out of which arterial hypertension (AH) was the most common (44.7%). Less common was coronary artery disease (CAD) (16.5%), which in 14.6% of patients was accompanied by AH. Chronic heart failure (CHF) NYHA class I-II was found in 19.4% of patients, and severe CHF (NYHA class III-IV) - in 4.9%. Arrhythmia was detected in 11.7% of patients. According to the clinical characteristics, no significant differences were found between the groups of men and women. AH affected 21.4% of men and 23.3% of women, CAD -10.7% and 5.8%, respectively. NYHA class I-II CHF were found in 8.7% of men and 10.7% of women, and severe CHF (NYHA class III-IV) - in 2 men and 3 women. Arrhythmia had a prevalence of less than 6% among both men and women. Anxiety or depression symptoms were reported in 29.1% and 27.2%, respectively. Combination of anxiety and depression symptoms was determined in 18.4%, symptoms of stress in 8.7% of patients. Symptoms of depression were found in women more often (p=0.023). The value of the median scores of the PHQ-9 questionnaire in the group of women was significantly higher than in the group of men (3.00 [1.00;8.00] and 1.00 [0;3.75], p=0.006). Depression symptoms were associated with female gender (OR 2.83;CI 95% 1.35-7.08). Despite the absence of gender differences in the prevalence of anxiety (18.4% and 10.7%, p=0.072), when comparing the values of the median scores of the GAD-7 questionnaire in the groups of men and women, the difference was statistically significant (1.00 [0;4.00] and 3.00 [2.00;7.00], p=0.001, respectively). Signs of stress among married people were less common in comparison with unmarried (2.9% vs 5.8%, p=0.037). Conclusion: Three months after discharge, no significant differences in clinical characteristics between men and women were found. Signs of anxiety or depression were detected in more than a quarter of patients with proven COVID-19-associated pneumonia. Women experienced symptoms of depression 3 times more often than men. Unmarried patients tended to experience stress more often.
