Brief Summary:
The purpose of this study is evaluate clinical outcomes and 30-day mortality after on-pump CABG.

Condition or disease
Kidney Failure

Detailed Description:
Eight hundred and seventeen patients was enrolled in this series and divided into to groups: Group AKI (-) - patients without acute kidney injury after on-pump CABG. Group AKI (+) - patients with acute kidney injury after on-pump CABG. AKI was defined as an absolute increase in serum creatinine (SCr) of more than or equal to 0.3 mg/dl (≥ 26.4 μmol/l) or a percentage increase in SCr of more than or equal to 50% (1.5-fold from baseline). The change in SCr concentration was defined as the difference between immediate postoperative concentration and the highest concentration during the stay in ICU. Clinical Outcomes and 30-day mortality was evaluate in this patients.

Group/Cohort
AKI (-)
Patients without acute kidney injury after on-pump CABG
AKI (+)
Patients with acute kidney injury after on-pump CABG



Primary Outcome Measures :
  1. To test the hypothesis that patients with acute kidney injury after on-pump CABG have higher 30-day mortality [ Time Frame: 30 days ]

Secondary Outcome Measures :
  1. To compare clinical outcomes in patients with and without acute kidney injury after on-pump CABG [ Time Frame: 30 days ]
