The Research Background and Rationale for the Trial
Patients with critical illness and endotheliopathy, characterized by endothelial damage markers, were the focus of the study. Preliminary studies showed that low-dose prostacyclin improved biomarkers reflecting endothelial health. Prostacyclin binds to endothelial cell receptors, enhancing endothelial integrity by regenerating glycocalyx and tight junctions, rather than primarily working as an anticoagulant or anti-inflammatory agent.
