    Abstract:
    BACKGROUND: We studied factors influencing early and late results in patients operated on for aortic valve replacement and coronary artery bypass graft. METHODS: 175 patients were retrospectively analysed over a 10-year period ending in December 2002. There were 135 males and 40 females with a mean age of 62.7 +/- 8.9 years; 109 were in NYHA class III/IV; 45 required an urgent operation, and 103 mechanical valves and 72 biological valves were implanted. RESULTS: There were 11 operative deaths (6.3 %). Statistical analysis (logistic regression) showed that previous myocardial infarction, poor NYHA class, and low LVEF had a significant effect on early death. There were 52 late deaths at a mean follow-up of 82.7 +/- 38.8 months. Using a Cox survival analysis for any causes, age, urgent operation, low LVEF, and creatinine had a strong impact on unfavourable late outcome. CONCLUSIONS: A combination of a patient-related factor (age), cardiac-related condition (low LVEF), co-morbid condition (renal dysfunction), and operative cause (urgent operation) is the most important predictor of late clinical outcome for this combined surgical procedure.
