Improvement of cardiac function after coronary artery bypass grafting surgery reduces the risk of postoperative acute kidney injury.

ABSTRACT:

Background

Pre-existing renal dysfunction is an independent risk factor for cardiac surgery-associated acute kidney injury (AKI). We aimed to investigate whether the improvement of postoperative cardiac function after coronary artery bypass grafting (CABG) surgery would affect the risk of AKI in patients with different levels of baseline renal function.

Methods

Data were collected from patients who underwent CABG surgery from January 2018 to April 2019. Patients were divided into normal (GFR ≥ 90 ml/min/1.73 m² ), non-CKD (60≤GFR < 90 ml/min/1.73 m² ), and CKD (GFR < 60 ml/min/1.73 m² ) groups. Improvement in cardiac function was defined as △LVEF (postoperative LVEF-preoperative LVEF) ≥ 10% preoperative LVEF. Patients were further divided int
