Assessment of ProEnkephalin to Detect Acute Kidney Injury (AKI) in Patients Hospitalized for Volume Overload Decompensated Chronic Heart Failure


About this study

The purpose of this study is to evaluate the baseline presence of plasma levels of biomarkers of renal injury and changes in these biomarkers during the course of in-hospital intravenous diuretic therapy can predict when threshold values that would indicate a clinically significant change in renal function that would warrant a change in diuretic therapy to occur.
