Inclusion criteria

* Male or female ≥ 18 years of age, with body weight ≤160 kg * Hospitalized for AHF; AHF is defined as including all of the following measured at any time between presentation (including the emergency department and outpatient clinic) and at the end of screening: * Persistent dyspnea at rest or with minimal exertion at screening and at the time of randomization * Pulmonary congestion on chest radiograph * Brain natriuretic peptide (BNP) ≥500 pg/mL or NT-proBNP ≥2,000 pg/mL * Systolic BP ≥125 mmHg at the start and at the end of screening * Able to be randomized within 16 hours from presentation to the hospital, including the emergency department and outpatient clinic * Received intravenous furosemide of at least 40 mg total (or equivalent) at any time between presentation (this includes outpatient clinic, ambulance, or hospital including emergency department) and the start of screening for the study for the treatment of the current acute HF episode * Renal impairment defined as an estimate glomerular filtration rate using the between presentation and randomization of ≥ 25 and ≤75mL/min/1.73m2, calculated using the Modification of Diet in Renal Disease formula (or modified sMDRD formula according to specific ethnic groups and local practice guidelines).
