Resumo: |
Introduction: Acute kidney injury is a complex syndrome characterized by rapid (hours or days) reduction in renal excretion that occurs in a wide variety of situations. It has wide variability of epidemiology and is a common complication in critically ill and intensive care patients. Acute kidney injury generate increased hospital costs and is associated with high mortality rates being independent predictor of death. Currently, three diagnostic criteria for acute kidney injury has been highlighted: RIFLE (Risk, Injury, Failure, Loss, and End-stage kidney disease), AKIN (Acute Kidney Injury Network) and KDIGO (Kidney Disease: Improving Global Outcomes). Objectives: To evaluate the incidence, morbidity and mortality associated with acute kidney injury (and its value as a predictor of 30-day mortality) in patients undergoing on-pump coronary artery bypass grafting (article 1), patients undergoing cardiac valve surgery (article 2), patients with elevated preoperative baseline creatinine (article 3) and, in general, in patients undergoing cardiac surgery (coronary artery bypass grafting or cardiac valve surgery) (article 4). Methods: (Article 1) Patients undergoing on-pump CABG from January 2003 to January 2008 (817 patients) were divided according to the AKIN classification in AKI (+) and AKI (-) patients. Multivariable logistic regression was used to determine independent predictors of 30-day mortality. (Article 2) Patients undergoing cardiac valve surgery from January 2003 to May 2010 (837 patients) were divided according to the presence of infective endocarditis. Cox regression analysis was used to determine independent predictors of 30-day mortality. (Article 3) Patients with elevated baseline serum creatinine underwent cardiac surgery (CABG or CVS) from January 2003 to June 2013 (918 patients) were evaluated to determine whether the development of post-operative acute kidney injury based on KDIGO criteria was an independent predictor of 30-day mortality. (Article 4) Patients undergoing cardiac surgery (CABG or CVS) between January 2003 and June 2013 (2804 patients) were evaluated to determine if acute kidney injury based on KDIGO criteria was an independent predictor of 30-day mortality. Results: (all articles) Patients who developed AKI postoperatively had more clinical complications. The 30-day mortality increased progressively in all stages of acute kidney injury. Based on AKIN and KDIGO criteria, AKI was an independent predictor of 30-day mortality. Conclusions: (all articles) In this population, acute kidney injury after cardiac surgery was an independent predictor of 30-day mortality. |
