Criteria
Inclusion Criteria:1. Signed informed consent form (ICF);
2. Males and females, 18 to 85 years of age (inclusive);
3. An admission within 36 hours prior to randomization for acute decompensated heart
failure (ADHF) episode, defined as:
1. Dyspnea, at rest or with minimal exertion;
2. Congestion on chest x-ray or lung US with B-type natriuretic peptide (BNP) ≥ 400
pg/mL or N-terminal-pro hormone BNP (NT-proBNP) ≥ 1400 pg/mL;
4. History of left ventricular ejection fraction (LVEF) < 40%;
5. Persistent hypotension defined as:
1. SBP between 75 and 90 mmHg for at least 2 hours prior to Screening;
2. SBP doesn't decrease by > 7 mmHg on two separate measurements during the last 2
hours prior to randomization;
6. Heart rate 75 to 150 bpm. If the subject is on a beta-blocker, the range is 60 to 150
bpm;
7. Echocardiogram confirming ejection fraction < 40% and no evidence of other pathology
to confound interpretation of cardiac physiology (eg, pericardial effusion).
Exclusion Criteria:
1. Current treatment (within 6 hours of Screening) with positive inotropic agents or
vasopressors, renal support including ultrafiltration, or mechanical circulatory,
ventilatory or renal support (intra-aortic balloon pump, endotracheal intubation,
mechanical ventilation, or any ventricular assist device);
2. Lactate > 2 mmol/L;
3. History of heart transplant or priority 1a heart transplant listing (United Network
for Organ Sharing; UNOS)
4. Ongoing treatment with digoxin (if digoxin was stopped before signing the ICF and the
digoxin plasma level is < 0.5 ng/ml, the patient may be enrolled);
5. Severe renal impairment (estimated glomerular filtration rate [eGFR] < 30 ml/min,
calculated by the Modification of Diet in Renal Disease [MDRD] formula);
6. Hypersensitivity to the study medication or any related medication;
7. Any of the following in the past 30 days: acute coronary syndrome, coronary
revascularization, myocardial infarction (MI), coronary artery bypass graft (CABG), or
percutaneous coronary intervention;
8. Stroke or transient ischemic attack (TIA) within 3 months;
9. Incomplete revascularization (patients with ischemic heart disease have to have had a
catheterization in the last year demonstrating that the main coronary arteries are
well revascularized);
10. Moderate or severe valvular disease, such as severe Aortic stenosis or regurgitation;
Severe tricuspid or mitral regurgitation;
11. Primary hypertrophic or restrictive cardiomyopathy or systemic illness known to be
associated with infiltrative heart disease;
12. Admission for AHF triggered primarily by a correctable etiology such as significant
arrhythmia, infection, severe anemia, acute coronary syndrome, pulmonary embolism,
exacerbation of chronic obstructive pulmonary disease (COPD), planned admission for
device implantation, or over-diuresis as a cause of hypotension;
13. Pericardial constriction or active pericarditis;
14. Life-threatening ventricular arrhythmia or implantable cardioverter defibrillator
(ICD) shock within the past month or history of sudden death within 6 months;
15. Cardiac resynchronization therapy (CRT), ICD, or pacemaker implantation within the
past month;
16. Sustained ventricular tachycardia in the last 3 months with no defibrillator;
17. Cor pulmonale or other causes of isolated right-sided HF or not related to left
ventricular dysfunction;
18. Acute respiratory distress syndrome;
19. Suspected sepsis; fever > 38° or active infection requiring IV antimicrobial
treatment;
20. Body weight < 40 kg or ≥ 130 kg;
21. Laboratory exclusions:
1. Hemoglobin < 9 g/dl,
2. Platelet count < 100,000/µl,
3. Serum potassium > 5.3 mmol/l or < 3.5 mmol/l;
22. Cirrhosis or malignancy with a life expectancy < 3 months;
23. Severe pulmonary or thyroid disease;
24. Pregnant or breast-feeding;
25. Ongoing drug or alcohol abuse;
26. Participation in another interventional study within the past 30 days.
