摘要

BACKGROUND Although early abdominal complications after coronary artery bypass grafting(CABG)with cardiopulmonary bypass(CPB)are rare,the associated mortality remains high.AIM To develop a risk score for the prediction of early abdominal complications after CABG with CPB.METHODS This retrospective study was performed in the Federal State Budgetary Establishment“Federal Center of Cardiovascular Surgery”of the Ministry of Health of Russia(the city of Chelyabinsk)and included data of 6586 patients who underwent CABG with CPB during 2011-2017.The risk factors taken for evaluation were compared between patients with early abdominal complications(n=73)and without them(n=6513).We identified the most important risk factors and their influence on the development of early abdominal complications after CABG with CPB.RESULTS Gender and the presence of postinfarction cardiosclerosis,chronic kidney disease,or diabetes in the anamnesis did not affect the occurrence of abdominal complications.The leading risk factors of the early abdominal complications after CABG with CPB were multifocal atherosclerosis,extracorporeal membrane oxygenation,intra-aortic balloon pump,atrial fibrillation,perioperative myocardial infarction,and the need for resternotomy in the postoperative period.The average value of the predicted probability was 0.087±0.015 in patients with early abdominal complications after CABG with CPB and 0.0094±0.0003 in patients without these complications.The percentage of correct classification turned out to be 98.9%.After calculating a score for each of the leading risk factors,we counted a total score for each particular patient.The highest risk was noted in patients with a total score of 7 or more.CONCLUSION The developed score predicts the risk of early abdominal complications after CABG with CPB and makes it possible to stratify patients by risk groups.
