Brief Summary

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

This prospective study aims to investigate the association between pericardial histopathologic inflammation grades (acute, chronic, or absent) and COVID-19 seropositivity in adult patients undergoing first-time isolated coronary artery bypass grafting (CABG). Pericardial tissue samples were collected during surgery and evaluated histopathologically, while preoperative COVID-19 serological testing was performed. The primary outcome is to determine whether COVID-19 seropositivity is associated with the severity of pericardial inflammation. Patients with prior cardiac surgery, active COVID-19 infection, systemic inflammatory diseases, chronic immunosuppressive therapy, or malignancy were excluded from the study.
