Score System for Operative Risk Evaluation in Coronary Artery Bypass Surgery / 대한흉부외과학회지

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.
