Prognosis and Diagnosis of Acute Gastrointestinal Dysfunction in Cardiac Surgery Patients

The purpose of this prospective observational clinical cohort study is to develop a scientifically based approach to the prediction and early diagnosis of intestinal dysfunction in cardiac surgery patients. The main questions that the study should answer: What are the main risk factors for the development of intestinal dysfunction? What specific and non-specific biomarkers can predict the development of intestinal dysfunction? The study participants will be monitored from the moment of hospitalization until the end of their stay in a medical facility
