Postoperative glycemic variability as a predictor for one-year mortality following coronary artery bypass grafting: a retrospective cohort study.

ABSTRACT:

Background

Increased postoperative glycemic variability (GV) has been shown to be associated with an increased risk for adverse outcomes. However, the impact of postoperative GV on the long-term mortality after cardiac surgery, particularly with regarding other associated interactive factors, remains unknown. In this study, we sought to investigate whether postoperative GV is associated with one-year mortality, and to determine whether preoperative hemoglobin A1C (HbA1C) levels or diabetes status contribute to the risk of GV-related one-year mortality following coronary artery bypass grafting (CABG).

Methods

Data from the Medical Information Mart for Intensive Care-IV (MIMIC-IV) database derived from 3,598 patients, who underwent their CABG surgery and subsequently admitted
