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
Coronavirus disease 2019 (COVID-19) is an infectious disease that affects almost all organs and systems. The main target is the respiratory system, but cardiovascular involvement is also common. Today, it is relevant to study the effect of complicated COVID-19 course on the patient’s cardiovascular system after hospital discharge — in particular, echocardiographic parameters. Aim. To study the echocardiographic parameters of patients with COVID-19 pneumonia 3 months after discharge from the hospital. Material and methods. The study included 106 patients with documented COVID-19 pneumonia. Patients underwent a comprehensive examination during hospitalization and 3 months ± 2 weeks after hospital discharge. The mean age of participants was 47±16 years (from 19 to 84 years), while 49% were women. Results. Three months after discharge, the average body mass index of the subjects was 28,2±5,7 kg/m2. Obesity was noted in 37,1%, cardiovascular diseases — in 52%. According to echocardiography, the prevalence of right ventricular (RV) dilatation was 2,9%, a decrease in tricuspid annular plane systolic excursion (TAPSE) — 9,5%, grade ≥2 tricuspid regurgitation — 1,9%, pulmonary hypertension (pulmonary artery systolic pressure >36 mm Hg) — 3,8%. The mean value of RV global longitudinal myocardial strain (GLMS RV) and global longitudinal myocardial strain (GLES RV) was 19,6±4,5 and 20,6±4,6, respectively. We found moderate correlations between GLMS RV and blood flow time through the left ventricular outflow tract (OT) (r=-0,436), through the mitral valve (r=-0,390;both p<0,0001) and through the RVOT (r=-0,348;р=0,004), with cardiac index (CI) (r=0,316;p=0,009), as well as between GLES RV and blood flow time through the LVOT (r=-0,411;p<0,0001) and RVOT (r=-0,300;p=0,005), and with CI (r=0,302;p=0,004). At the same time, the correlation of GLES RV with RV fractional area change (FAC) was weak (r=-0,283;p=0,007), while there was no correlation with the TAPSE. In addition, correlation of GLMS RV with these parameters were not defined. Conclusion. Three months after COVID-19 pneumonia, RV strain parameters were shown to have stronger relationships with time characteristics of flows in LVOT and RVOT, as well as with CI, than with such generally accepted characteristics of RV function as FAC and TAPSE.
ABSTRACT
Aim. To compare the cardiovascular and psychological profile of young military population after coronavirus disease 2019 (COVID-19) with/without pneumonia. Material and methods. We examined 26 military men under 30 years of age (22,3±3,7 years/21,0 [19,8;24,3] years) with documented COVID 19 (3 months±2 weeks after two virus-negative polymerase chain reaction tests). The participants were divided into 2 groups: experimental group (n=16) — those with COVID-19 pneumonia;comparison group (n=10) — those without pneumonia. All subjects underwent a complex of clinical and diagnostic tests. Results. Military men with COVID-19 pneumonia were significantly older (23,0 [20,5;28,5] years vs 19,5 [19,0;20,0] years, p=0,001). They had a prolonged PQ interval (154,5 [140,0;163,5] ms vs 137,0 [134,0;144,0] ms;p=0,014). According to echocardiography, the following parameters were significantly larger in experimental group: anteroposterior right ventricular dimension (26,0 [24,5;27,5] mm vs 23,5 [22,0;25,0] mm, p=0,012), right atrium length (48,0 [46,0;51,5] mm and 45,5 [44,0;47,0] mm, p=0,047), tricuspid regurgitation peak gradient (18,0 [15,5;22,0] mm vs 14,0 [12,0;20,0] mm, p=0,047), pulmonary artery systolic pressure (PASP) (30,3 [27,6;34,0] mm Hg vs 23,0 [20,5;30,5] mm Hg, p=0,038), mean pulmonary artery pressure (20,3 [18,9;22,7] mm Hg vs 16,8 [14,5;20,6] mm Hg, p=0,038). The estimated pulmonary vascular resistance was significantly higher in the study group (1,50 [1,2;1,8] Wood units vs 1,17 [1,1;1,2] Wood units, p<0,001). The groups did not differ significantly in terms of symptoms of stress (perceived stress scale score of 10) and anxiety and depression disorders (GAD7 and PHQ9 questionnaires), quality of life (SF-36 survey). Conclusion. In young military personnel, COVID-19 pneumonia in the long term after the disease is associated with longer PQ interval, older age and larger right heart sizes on echocardiography, as well as with a higher tricuspid regurgitation peak gradient, PASP, mean pulmonary artery pressure, and pulmonary vascular resistance. In this category of population, no association was found between the severity of COVID-19 and psychological status parameters.
