Abstract
-
BACKGROUND: The purpose of this study is to assess a score system for operative risk evaluation of CABG.
MATERIAL AND METHOD: From January 2001 to September 2005, retrospective study for various perioperative factors of 2993 cases was done.
RESULT: The early operative mortality was 2.4% and the beta coefficients of 7 core variables related to it (preoperative LV dysfuction, preoperative renal failure, MI within 1 week, reoperation, combined surgery, preoperative atrial fibrillation, preoperative IABP) were adjusted to score system. ROC curve and Hosmer and Lemeshow goodness of fit test was done.
CONCLUSION
This score system was effective in assessing operative risk of CABG. But It is necessary to gather larger volume of case and perform multicenter study.
