Persistent Kidney Injury at Hospital Discharge After Cardiac Surgery With Cardiopulmonary Bypass in Patients With Normal Preoperative Serum Creatinine and Normal Estimated Glomerular Filtration Rate

摘要

Objective: Acute kidney injury is a serious complication after cardiac surgery. Although it resolves in most cases, a significant portion of patients persistently have raised creatinine values at hospital discharge. These patients are at greater risk for developing chronic kidney disease and mortality. Therefore, the present study aimed to ascertain risk factors of persistent acute kidney injury after cardiac surgery in patients with normal preoperative renal function.
