Acute heart failure (HF) management is a complex and often involves a delicate balance of both cardiac and renal systems. Although pharmacologic diuresis is a mainstay of the pharmacologic management of decompensated HF, ultrafiltration (UF) represents a nonpharmacologic approach in the setting of diuretic resistance. We conducted a cross-sectional analysis of the 2009 through 2014 hospitalization data from the National Inpatient Sample. The study population consisted of hospitalizations with a discharge Diagnosis Related Groups of HF who were older than 18 years of age, did not have end-stage kidney disease, acute kidney injury and had not undergone hemodialysis or hemofiltration. There were 6,174 hospitalizations which included UF among the 7,799,915 hospitalizations for HF. Hospitalizations which included UF were among patients significantly younger in age (68.1 ± 1.0 vs 73.8 ± 0.1 years), male (61.9% vs 47.7%), and with higher prevalence of co-morbid conditions including chronic kidney disease (58% vs 31%), diabetes mellitus (53% vs 42%), and higher rates of co-morbidity (Charlson comorbidity score ≥2, 92% vs 80%). All-cause mortality was significantly higher among hospitalizations which included an UF (4.68% vs 2.24%). Hospitalizations with UF had a longer mean length of stay (6.2 vs 4.3 days, p
