In this study, the trends in results are analyzed and causes are suggested. METHODS Prospectively collected data concerning 4,839 CABG(More)
Results of cardiac surgery were analyzed using a database that included plasma creatinine levels in 2,214 patients, of whom 507 had preoperative renal dysfunction (creatinine clearance < 0.9 mL x s(-1) x m(-2)). Logistic regression and propensity score analyses found preoperative renal dysfunction to be an independent predictor of morbidity and mortality.(More)
