About

The study will evaluate the impact of a combined device-drug strategy with Impella 5.5 with best practices and optimized GDMT on heart recovery outcomes in patients with decompensated heart failure and cardiogenic shock.

Full description

This is a prospective, single arm, multi-center, post-market, on-label study. Patients presenting with heart failure cardiogenic shock (HF-CS), an intentional device-supported strategy with Impella 5.5 for optimization of guideline-directed medical therapy (GDMT) combined with best practices improves outcomes over standard of care. The study objectives are to evaluate the impact of a combined device-drug strategy with Impella 5.5 with best practices and optimized GDMT on heart recovery outcomes in patients with decompensated heart failure and cardiogenic shock.

Inclusion criteria

Age ≥ 18 and < 80 years
Subject has signed the Informed Consent Form. If the subject has been enrolled via an LAR, the subject must provide assent, the assent will be documented.
LVEF ≤ 40%
Subject is presenting with decompensated heart failure and meets at least one (1) of the following cardiogenic shock criteria:
1. Sustained episode of systolic blood pressure ≤ 90 mmHg for at least 30 minutes or need for vasoactive agents to maintain such blood pressure.
2. Cardiac index (CI) < 2.2 L/min/m2 determined to be secondary to cardiac dysfunction, in the absence of hypovolemia.
3. Require support with an intra-aortic balloon pump (IABP)
4. Serum lactate >2 mmol/L
Subject has inadequate heart failure GDMT based on the most recent outpatient prescription prior to index admission, defined as:
1. On 2 or less of the 4-Pillar HF Drug Classes (BB, MRA, SGLT2i, and RASi)
2. If on BB and RASi, at least one of the two medications is < 50% of the maximal target dose.

Exclusion criteria

Underlying unmodifiable conditions that limit initiation of GDMT prior to enrollment, including but not limited to:
1. Drug allergies or hypersensitivities* to HF GDMT medications, unless alternative can be identified.
  
  *Drug allergy/hypersensitivity is an immune-mediated reaction to a medication. Adverse reactions must be a result of immune or inflammatory cell stimulations by the mеԁiсаtion.
2. Known bilateral renal artery stenosis
3. Type 1 diabetes
4. 2o or 3o AV block, unless pacemaker is in place
5. Angioedema, hereditary or idiopathic
6. Pregnancy, known or confirmed by a pregnancy test if of childbearing potential
ST-segment elevation or acute coronary syndrome (ACS) prior to enrollment
Septic shock, shock from non-cardiac origins, or mixed shock
SCAI Stage E cardiogenic shock per study definition (Appendix C) prior to enrollment
In cardiac arrest prior to enrollment
Intra-aortic balloon pump (IABP) use >24 hours from the onset of cardiogenic shock if placed at the enrolling site or >48 hours if transferred on IABP prior to enrollment
On mechanical circulatory support other than IABP (i.e. ECMO, Impella CP, etc) or on mechanical ventilation for non-procedural reasons prior to enrollment
Revascularization or cardiac surgery within 30-days of the index hospitalization date or decision to undergo revascularization or cardiac surgery made prior to enrollment
Infiltrative/restrictive cardiomyopathy (sarcoidosis and amyloidosis), hypertrophic cardiomyopathy, constrictive pericarditis, pericardiac tamponade, or fulminant myocarditis (giant cell or immune checkpoint inhibitor)
Complex adult congenital heart disease
Primary severe valvular disease
Predominant RV dysfunction per Investigator's discretion
History of heart transplant or listed for heart transplant or planned for heart transplantation prior to enrollment.
Planned to be implanted with a permanent VAD within 180-days of the index hospitalization date.
Continuous outpatient inotropic support prior to the index hospitalization date.
Planned to pursue palliative care or hospice, or life expectancy of less than 1 year due to non-cardiac illness at the time of index hospitalization date.
Currently on dialysis, or has pre-existing end-stage chronic kidney disease (stage 4 and above), or has nephropathy of hereditary, infectious, or autoimmune origin.
Pre-existing liver disease including liver cirrhosis, alcoholic hepatitis, metabolic dysfunction associated steatohepatitis (MASH), or genetic liver disease.
Pre-existing pulmonary disease with oxygen dependency.
History of stroke or intracranial hemorrhage ≤ 90 days prior to the index hospitalization date, or a history of cerebrovascular disease with significant (> 80%) uncorrected carotid stenosis, or any permanent neurological deficit with modified Rankin Scale (mRS) >2.
Any contraindication that precludes placing an Impella 5.5®, including but not limited to:
1. Aortic valve stenosis/calcification with orifice area ≤ 0.6cm2 or aortic insufficiency of any grade greater than mild on pre-procedure echocardiography.
2. Presence of mechanical aortic valve or heart constrictive device
3. Thrombus in the left atrium or ventricle
4. Infection of the planned procedural access site or suspected systemic active infection.
5. Severe arterial disease precluding placement of Impella
6. Presence of Atrial or Ventricular Septal Defect
7. Left ventricular rupture
8. Cardiac tamponade
9. Combined cardiorespiratory failure
Intolerance to anticoagulant or antiplatelet therapies, or will refuse blood transfusions.
Subject has other medical, social or psychological problems that, in the opinion of the Investigator, compromises the subject's ability to give written informed consent (or assent if LAR) and/or to comply with study procedures.
Participation in the active treatment or follow-up phase of another clinical study of an investigational drug or device.
Subject belongs to a vulnerable population, such as prisoners, pregnant women, handicapped, mentally disabled persons, or economically or educationally disadvantaged persons per 21CFR56.111(a)(3) and 111(b).
