Risk factors for AKI after left ventricular assist device implantation (14,20,51)

PreoperativeIntraoperativePostoperative
Serum creatinine >1.5 mg/dlLonger cardiopulmonary bypass timeIntra-aortic balloon pump
Worse right ventricular functionBleeding (>1 L)Reoperation
Older ageNumber of transfusionsLiver dysfunction
Higher LVAD scoreaSepsis
Malnourishment (low albumin, total protein)High central venous pressure
Kidney size <10 cm
Renin-angiotensin system inhibitors use immediately before surgery
  • LVAD, left ventricular assist device.

  • a LVAD score is a measurement of illness severity derived from the following factors in HeartMate II: (1) postimplantation shock, (2) ventilatory status, (3) central venous pressure >16 mm Hg, and (4) prothrombin time >16 s.
