Abstract
AIM: to study frequency and risk factors of AKI and also features of its clinical course in the postoperative period in patients undergoing CABG in a planned order. PATIENTS AND METHODS. 548 patients (331 men and 217 women) aged from 42 to 68 years (57,9±8,3 years) were examined before and after CABG by cardiopulmonary bypass. A serum creatinine (sCr) levels and glomerular filtration rate were defined before operation, daily within 7 days after CABG, at discharge from the hospital and in 3 months after discharge. AKI was diagnosed and classified by level of sCr using criteria of RIFLE. RESULTS. AKI was diagnosed in 132 patients (24,1%) after CABG, out of them 109 patients (19,9%) had mild AKI, 64 patients (11,7%) – moderate AKI and 29 patients (5,3%) – with severe AKI. Also transient AKI was revealed in 58,3% of the cases, persistent AKI – in 39,4% of the cases and resistant AKI – in 2,3% of the cases. Renal replacement therapy (hemodialysis) was performed in 7 patients (36,8%). An in-hospital mortality among patients with and without AKI was 7,6% and 2,2% respectively (χ2 = 7,23; p = 0,007). CONCLUSION. Thus, sCr levels in patients with AKI were associated with such factors as characteristics of severity of CABG surgery, comorbid conditions such as congestive heart failure, hypertension, atrial fibrillation and age higher than 60 years.
