Brief summary: Different doses of relaxin will be compared to placebo to determine efficacy and safety for the treatment of patients hospitalized with acute heart failure

Detailed description: This is an international, randomized, double-blind, placebo-controlled, Phase II/III trial of intravenous recombinant relaxin for the treatment of signs and symptoms in patients hospitalized for acute decompensated heart failure. The Phase II pilot study has completed; the Phase III main portion of the trial is ongoing.

Eligibility criteria: Inclusion Criteria:

* Hospitalized for acute heart failure
* Dyspnea at rest or with minimal exertion
* Pulmonary congestion
* Able to provide informed consent
* Systolic blood pressure \> 125 mmHg
* Impaired renal function defined as an eGFR of 30-75 mL/min/1.73m2

Exclusion Criteria:

* Use of other IV therapies for acute heart failure
* Fever or sepsis
* Recent major neurologic event
* Recent major surgery
* Recent acute coronary syndrome
* Other recent investigational drug use

Primary outcomes:
measure: Relief of dyspnea in acute heart failure
timeFrame: Up to day 5
Secondary outcomes:
measure: Days alive and out of hospital
timeFrame: Up to day 60
measure: CV death or rehospitalization due to heart failure or renal failure
