Brief Summary

In a prospective observational study during the six-month duration, coronary artery bypass graft surgery (CABG) and valve repair surgery (mitral, mitral, and aortic valve and/or tricuspid valve) patients were investigated for hepatic dysfunction. All patients were divided into two groups as with or without hyperbilirubinemia, and this was defined by the occurrence of a plasma total bilirubin concentration of more than 34 µmol/L (2 mg/dL) in any measurement during the postoperative period. Our goal was to determine the risk factors associated with hepatic dysfunction in patients undergoing open-heart surgery with cardiopulmonary bypass. The collected parameters include; alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP), total bilirubin (TBIL), and gamma-glutamyl transpeptidase (GGT) and albumin preoperatively and on postoperative days 1, 3 and 7. Possible preoperative, intraoperative, and postoperative risk factors were investigated. Logistic regression analysis was done to identify the risk factors for postoperative hyperbilirubinemia.

Open-heart surgery

Patients undergoing open-heart surgery with cardiopulmonary bypass

Procedure: Open-Heart Surgery for nine months durationOther: Relation between possible risk factors and hyperbilirubinemiaOther: Follow-up period

Interventions

In a single group of patients including 340 patients undergoing open-heart surgery during a period of nine months, the collected parameters include; alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP), total bilirubin (TBIL), and gamma-glutamyl transpeptidase (GGT) and albumin preoperatively and on postoperative days of 1, 3 and 7. All patients were divided into two groups as with or without hyperbilirubinemia, and this was defined by the occurrence of a plasma total bilirubin concentration of more than 34 µmol/L (2 mg/dL) in any measurement during the postoperative period. For each diagnostic test, a comparison within the group for different time points was statistically evaluated by analysis of variance tests.

Also known as: Type of open-heart surgical operation (coronary artery bypass graft operation, mitral valve, aortic valve or multiple valvular surgeries), Hyperbilirubinemia, Hepatic function related tests
Open-heart surgery

Possible preoperative, intraoperative, and postoperative risk factors were investigated. The relations between hyperbilirubinemia and possible risk factors are sought by the use of the statistical analysis methods including logistic regression analysis.

Open-heart surgery

All patients were investigated for a period of ten days postoperatively. During this period, intensive care unit (ICU) stay, in-hospital stay, and all adverse events were recorded.
