Patients receiving elective cardiac or thoracic aorta surgery will be monitored for the development of postoperative hyperbilirubinemia. Collection of data will include patient baseline demographic characteristics, laboratory and echocardiographic findings, procedural factors of the surgery, and early postoperative variables. Serial postoperative liver function testings will be done during the hospitalization. Postoperative hyperbilirubinemia is defined as serum bilirubin level of 3mg/dL.
This study aims to evaluate the incidence and risk factors of hyperbilirubinemia following major cardiac or thoracic aorta surgery, and to determine the clinical impacts of the hyperbilirubinemia on postoperative mortality and morbidity.
