In-hospital mortality and complications following coronary artery bypass surgery; Is it possible to predict with preoperative values?

Abstract

Objective: The aim of this study is to evaluate short-term complications and mortality in patients undergoing isolated coronary artery bypass surgery with preoperative predictors commonly used in the literature. Methods: A total of 518 patients who underwent coronary artery bypass surgery using cardiopulmonary bypass pump were retrospectively investigated. Preoperative fasting blood glucose, hemoglobin, neutrophil, platelet count, erythrocyte distribution width, mean platelet volume, platelet lymphocyte ratio, neutrophil lymphocyte ratio, metabolic syndrome criteria were recorded. These preoperative data have been investigated in relation to postoperative short term complications and mortality. Results: Twenty-six (5%) out of 518 patients exited within postoperative 30 days. Mortality was associated with advanced age, presence of hypertension, fasting blood glucose and platelet lymphocyte ratio. However, in multivariate analyzes, only advanced age was seen as an independent predictor of mortality. At least one postoperative complication was seen in 66 (12.7%) patients. Age, fasting blood glucose, hemoglobin value, mean platelet volume, neutrophil lymphocyte ratio were found to be associated with the development of complications. However, in multivariate analyzes only age was seen as independent predictor of development of complications. Conclusion: It is not possible to predict mortality and complications in patients undergoing coronary artery bypass surgery using only preoperative data.
