Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The food supplement Endocalyx is considered to support the endothelial glycocalyx integrity by supplying sulfated polysaccharides, anti-oxidant enzymes and additional substrates for glycocalyx synthesis. The investigators will study the effect of Endocalyx on endothelial, vascular and left ventricular myocardial function in patients with COVID-19 infection.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Sixty patients who have been hospitalized due to COVID-19 infection will be randomized to receive food supplement Endocalyx (4 capsules per day) (n=30) or placebo (n=30) for 4 consecutive months.
