About
Single center, prospective, randomized, non-blinded research study comparing intravenous vasodilator infusion vs. inotropic infusion in patients admitted to the hospital or in the emergency room at Montefiore Medical Center presenting with the diagnosis of acute decompensated systolic heart failure with low cardiac output but no hypotensive.
Full description
The objective of the study is determine if the administration of diuretics with intravenous sodium nitroprusside (vasodilator therapy) in comparison to intravenous dobutamine (inotropic therapy) will lead to a reduction in the primary and secondary endpoints in patients with acute decompensated systolic heart failure with low cardiac output and no hypotensive.

Inclusion criteria
History of heart failure reduced ejection fraction (HFrEF), New York Heart Association (NYHA) class IV and known left ventricular ejection fraction (LVEF ) ≤ 40% within the last 6 months by any of the following imaging techniques: echocardiogram, radio-nuclear stress test, ventriculogram or cardiac magnetic resonance imaging (CMR) performed within 6 months.
Hospitalized or presented to the emergency department for acute decompensated heart failure (ADHF) with the anticipated requirement if intravenous (IV) therapy (including IV diuretics). ADHF is defined as including all of the following measured at any time between the presentation (including the emergency department) and the end of the screening:
Clinical suspicious of low cardiac output state; consider by the presence of any of the following signs or symptoms of hypoperfusion: narrow pulse pressure, cold extremities, mental obtundation, declining renal function, and/or low serum sodium.
Systolic blood pressure (SBP) measured ≥ 90 but < 120 mmHg at the start and the end of the screening, without use of an intravenous vasopressor therapy.
Hemodynamic criteria: CI ≤ 2.2 L·min-1·m-2 based on CO calculated by Fick formula and PCWP ≥ 20 mmHg measured by right heart catheterization at the time of the enrollment and confirmed by Swan-Ganz measurement upon arrival to the Cardiac Care Unit (CCU).
Able to be randomized within the first 24 hours from the presentation to the hospital, including the emergency department.
