Changes in cardiac hemodynamic parameters in patients after COVID-19

Abstract

Aim. To study cardiac hemodynamic disorders in patients 3, 6 and 12 months after coronavirus disease 2019 (COVID-19).Material and methods. Sixty-six patients with bilateral pneumonia (mean age, 36,1 years), treated for COVID-19, underwent echocardiography, Doppler ultrasound of hepatolienal blood flow vessels after 3, 6, 12 months. Patients were divided into groups based on computed tomography (CT) data: group 1 — 21 patients with CT1, group 2 — 25 patients with CT2, group 3 — 20 patients with CT 3-4. In the 3rd group, 60% of patients had excessive weight. IBM SPSS Statistics Version 25.0 was used.Results. Three months after the disease in all groups, there was a impairment of diastolic parameters studied on the tricuspid valve. Patients of the 3rd group had pulmonary hypertension, an increase in splenic vein diameter, and the spleen area. After 6 and 12 months. in all groups, there was an improvement in right ventricular diastolic filling. In group 3, pulmonary artery systolic pressure after 6 months decreased by 6,0 (3,7; 6,5)% (p=0,03), after 1 year by another 8,6 (5,4; 9,1)% (p=0,017). The diameter of the inferior vena cava after 6 months decreased by 4,8 (2,0; 10,2)%, and a year later by another 5,0 (4,4; 6,1)% (p=0,001); the splenic vein diameter decreased after 6 months by 7,3 (3,2; 10,4)% (p=0,005). The left ventricular (LV) global systolic strain reduced after 3, 6 and 12 months.Conclusion. All patients 3 months after COVID-19 had cardiac hemodynamic disorders, which further by 6 and 12 months tend to normalize right ventricular diastolic filling. In patients with CT 3-4, by 12 months after the disease, normalization of pulmonary artery systolic pressure was also noted, a decrease in the diameter of the inferior vena cava and splenic veins, and a decrease in the global LV systolic strain persisted.
