Risk Factors for Postoperative Respiratory Mortality and Morbidity in Patients Undergoing Coronary Artery Bypass Grafting

Nowadays, coronary artery bypass grafting (CABG) is considered to be one of the mostcommon surgical procedures. This procedure has been the main topic in many clinicalresearch studies, which have assessed the effect of the procedure on patients’ outcomes.Like other surgical procedures, this procedure is also accompanied by a number of unwantedcomplications, including those of the respiratory system. Since the respiratorysystem plays an integral role in defining the clinical outcome of patients, improvementsin studies that can assess and predict clinical outcomes of the respiratory system, assumegreater importance. There are a number of predictive models which can assesspatients in the preoperative period and introduce a number of risk factors, which couldbe considered as prognostic factors for patients undergoing CABG. The respiratory systemis among the clinical systems that are assessed in many prediction scoring systems.This review assesses the main studies which have evaluated the possible risk factors forpostoperative respiratory mortality and morbidity, in patients undergoing CABG.
