Background: Acute Kidney Injury (AKI) after cardiac surgery is a serious complication.
AKI could occur in 30% of patients, and 1-5% develop severe kidney injury. The
present study aimed to evaluate the use of the Cleveland Clinic Score (CCS) to
identify patients at higher risk of AKI after cardiac surgery.
Methods: This study included 100 patients, 83 were males, and the mean age was
52.47±11.3 years. All patients had elective operations; 30% had isolated valve
surgery, 64% had isolated coronary artery bypass grafting (CABG), and 6% had
combined CABG and valve operation.
Results: Creatinine serum level ranged between 0.5-2 mg/dL with a mean of
0.98±0.32 mg/dL. Seventy-four patients had good renal function postoperatively,
and their CCS was 1.45±0.36, while 26 patients had renal impairment, and their CCS
was 12.5±0.44 (P= 0.001). Patients who had AKI were older (62.87±8.7 vs. 49.9±13.9;
