Summary

Severe SARS-CoV-2 disease is characterized by a progressive hypoxemic respiratory failure. Autopsies from these patients show severe endothelial damage with extensive vascular thrombosis, microangiopathy, and occlusion of alveolar capillaries and, finally, evidence of new vessel growth through intussusceptive angiogenesis. This research aims to study endothelial damage and angiogenesis biomarkers and its association with major cardiovascular events.

Detailed description

To study the presence of endothelial damage and angiogenic biomarkers with major cardiovascular events, the investigators will perform an observational study to evaluate plasma biomarkers concentrations in Covid-19 patients hospitalized in critical care units. After ethical review board approval, the investigators will select 40 patients admitted to intensive care units (ICU). After patient written consent or if the participants are unable to consent, after a relative subrogated acceptance, the investigators will collect blood samples in the first 24 hrs and on the 10th day of hospitalization. Venous blood samples are collected. After obtaining all samples, serum Syndecan-1, thrombomodulin, ANG-2, FGF basic, HGF, IL-8, PDGF-BB, TIMP-1, TIMP-2, TNFα y VEGF will be determined by a researcher blinded to the patient using commercially available Elisa kits. The concentration of each biomarker at each sample time will be compared. The investigators will observe clinical outcomes after one, 3, 6, and 12 months after the hospitalization. The investigators found no previous data of this measurement in the COVID-19 scenario. In this observational study, the investigators select a sample size on convenience for the primary outcome.
