Syndecan-1 in Acute Decompensated Heart Failure　– Association With Renal Function and Mortality

Background:Heart failure (HF) is a leading cause of hospitalization throughout the world, and the mortality rate remains elevated. HF is frequently complicated by acute kidney injury (AKI), worsening the patient’s prognosis. There have been no studies evaluating the role that endothelial glycocalyx damage plays in HF patients and its association with AKI and mortality.Methods and Results:We measured several endothelial biomarkers in 201 consecutive patients with acute decompensated HF (ADHF) during emergency department (ED) admission. In-hospital mortality, AKI development and 6-month mortality rates were assessed. ADHF patients with worsening renal function had higher levels of syndecan-1 but not those patients with stable chronic kidney disease. Syndecan-1 levels during ED admission were predictive for AKI during the hospital stay (AUC 0.741, P
