Abstract

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; P<0.001) and had higher preoperative creatinine (1.1±0.32 vs. 0.94±0.31; P= 0.03). AKI was more common in diabetics (23 (88.5%) vs. 28 (37.85, P<0.001) and patients with COPD (6 (23.1%) vs. 3 (4.1%); P= 0.004). CCS score was significantly higher among the different degrees of severity of AKI.

Conclusion: Cleveland Clinic Score could be good for predicting acute kidney injury after cardiac surgery.
