- Public TitleEvaluation of a temporary pump in patients with decompensated heart failure
- Scientific TitleEvaluation of the intra-aortic balloon pump in patients with decompensated heart failure
- ACRONYMIABP-HF
- hypothesisIn severe heart failure, the heart¡¯s pumping power is weak, leading to fluid retention and hospital admission of the affected patient. This project will investigate if a temporary pump (intra-aortic balloon pump, IABP) in the aorta will treat fluid overload so that patients are bridged faster towards recovery or to surgical assist device implantation.
- Healt Condition(s) or Problem(s) studiedCardiogenic shock
- Inclusion criteriaCONGESTIVE HEART FAILURE (FIRST EPISODE (¡°DE NOVO¡±) OR WORSENING OF CHRONIC HEART FAILURE) WITH THE FOLLOWING CHARACTERISTICS:
BLOOD PRESSURE Systolic <100 mm Hg
PHYSICAL EXAMINATION Fluid retention (elevated central venous pressure, palpable liver, edema)
ECHO At least moderate tricuspid regurgitation and/or mitral valve regurgitation. Dilated inferior caval vein.
INVASIVE MEASUREMENTS PCWP >15 mmHg; CVP >12 mmHg; SvO2 <55%
NT-PROBNP >200 pg/mL
FLUID BALANCE Neutral or positive despite fluid restriction (1.5L/24h) and administration of high dosages of intravenous diuretics*
TOGETHER WITH: Dysfunction of at least 1 other organ# PCWP, pulmonary capillary wedge pressure; CVP, central venous pressure.
* Bolus dosage (equal to) 80 mg intravenous furosemide followed by total intravenous dosage equal to total daily loop diuretic dose in furosemide equivalents and (if necessary) doubled, for at least 12h.

- Brief summaryRationale: In severe heart failure, the heart¡¯s pumping power is weak, leading to fluid retention and hospital admission of the affected patient. This project will investigate if a temporary pump (intra-aortic balloon pump, IABP) in the aorta will treat fluid overload so that patients are bridged faster towards recovery or to surgical assist device implantation.
Objective: Evaluation of the benefit of IABP counterpulsation in patients with diuretic-resistant congestive heart failure. Secondary objectives:
• To lower the burden of disease/improve symptoms, to shorten duration of stay in the hospital, to improve the function of other organs than the heart, and to bridge patients faster to final treatment (medical vs. LVAD vs. transplantation vs. palliative care).
• To create evidence based knowledge and gain better understanding of the disease, resulting in tailor-made treatment. Study design: Open-label randomized controlled parallel, partial cross-over, study in patients with diuretic-resistant congestive heart failure.
Study population: Patients with congestive heart failure, refractory to treatment with high dosages of intravenous diuretics.
Intervention (if applicable): Patients will be randomized to IABP (without inotrope, group I) or inotrope (without IABP, group II). Main study parameters/endpoints: Delta SvO2 at T=3h. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Patients in evident heart failure refractory to high-dose diuretic therapy have a poor prognosis. Escalation therapy will be given by either inotropic therapy (carrying the risks of arrhythmias) or an IABP (carrying the risks of access site and remote complications, <1%). Both treatment options have been successfully applied to save patients.
