Predictors of early mortality in acute cardiac patients requiring renal replacement therapy: a single center experience.

Acute kidney injury (AKI) frequently complicates the clinical course of critically ill patients admitted to an intensive care unit (ICU) and constitutes an independent predictor for patient survival [1], [2] and [3]. Severe acute kidney injury (AKI) requiring renal replacement therapy (RRT) occurs in about 5% of the critically ill population and is, depending on the definition used, associated with a very high in-hospital mortality rate [4], ranging from 38% to 80% [5] and [6]. The present investigation is aimed at assessing the predictors of in-Intensive Cardiac Care Unit (ICCU) mortality in 297 acute cardiac patients requiring RRT and consecutively admitted to our ICCU from January 2004 to December 2012.
