Abstract

Background: Coronavirus disease 2019 (COVID-19) is a worldwide pandemic that developed from SARS-CoV-2, a coronavirus that causes severe acute respiratory syndrome and is marked by extensive lung involvement. Aim and objectives: To assess the incidence and severity of pulmonary hypertension (PH) in healthy individuals nine months following the resolution of a mild to moderate COVID-19 infection in the lungs. Patients and methods: In this prospective investigation, 70 patients with mild to moderate COVID-19 lung infections were evaluated at AL-Hussein and Bab El-Sharia (Saied Galal) Hospitals. Results: Both the normal and high-pressure groups had mean tricuspid annular plane systolic excursions (TAPSE) of 25.8±2.4mm and 17.2±3.2mm, respectively. The average strain in the normal pressure group was -19.3±2.3% RV-GLS, while in the high-pressure group it was -26.7±3.1%. An independent sample t-test (P<0.001) revealed a statistically significant distinction between the groups with respect to TAPSE and RV-GLS. Conclusion: Even in cases of minor pneumonia, pulmonary hypertension is a common consequence of COVID-19. Although its historical development is still up in the air, its longevity appears to be underappreciated. Both the initial pulmonary injury's severity and the inflammatory response's magnitude seem to play a role.
