[Heart surgery in patients with chronic renal insufficiency: risk factors, outcome, management]

Cardiovascular diseases are one of the most common causes of hospitalization. Renal failure is a very important risk factor in patients undergoing heart surgery. So far few authors have written about non-dialysis dependent patients with mild renal insufficiency undergoing heart surgery. The purpose of this study is to present most important risk factors and outcomes in patients with different stages of renal insufficiency. The authors have studied attentively non-dialysis dependent patients with mild renal insufficiency because of high risk of pooperative renal failure in this population. To diminish high risk of perioperative death in these patients, there is a need for very close co-operation between cardiologists, cardiac surgeons and nephrologists.
