Prolonged stay and endothelial dysfunction in hospitalized patients with covid-19

Introduction: COVID-19 is not only a respiratory disease, produces a severe systemic and multi-organ response. This illness generates vascular disorders, leading the patient to endothelial dysfunction. It acutely and chronically affects the patient's evolution, prolonging the patient's stay and worsening life prognosis. Objective(s): To evaluate differences in endothelial dysfunction present in patients hospitalized for COVID-19 who had a hospital stay longer than 18 days compared to those who did not. Method(s): A prospective cohort study was conducted. Hospitalized patients with confirmed SARS-COV 2 andolder than 18 years were included. Subjects in whom endothelial function markers could not be processed wereexcluded. Endothelial dysfunction was evaluated using E-selectin, endothelin-1, glutathione-s-transferase, arginase, and MDAM. A prolonged hospital stay was established >=18 days. Result(s): A total of 165 patients were evaluated, the average age of the population was 57.18 +/- 13.37 years, 73.33% were men. Subjects with prolonged hospital stay were older (59.38 +/- 12.08 vs 51.15 +/- 14.96, p=0.004), a higher number of patients required intubation (87.60 % vs 75, p=0.049) and e-selectin (1 [0.79 - 1.32] vs 0.88 [0.68 -1.14], p=0.0323) compared to subjects without prolonged hospital stay. Conclusion(s): Hospitalized patients over 18 days showed elevated levels of E-selectin reflecting endothelial damage, affecting vascular homeostasis, added to this, a significant number of them were intubated, increasing the risk of mortality, as well as future cardiovascular complications.
