Eligibility Criteria

Age18 Years - 80 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Age ≥ 18 and \< 80 years
  • Subject or subject's legally authorized representative (LAR) has signed the Informed Consent Form
  • LVEF ≤ 40%
  • Subject is presenting with decompensated heart failure and meets at least two (2) of the following cardiogenic shock criteria:
  • Hypotension (sustained episode of systolic blood pressure ≤ 90 mmHg for at least 30 minutes or need for inotropic/vasoactive agents to maintain such blood pressure)
  • Hypoperfusion (physical sign(s) of organ hypoperfusion or serum lactate \>2 mmol/L)
  • Cardiac index (CI) \< 2.2 L/min/m2 determined to be secondary to cardiac dysfunction, in the absence of hypovolemia
  • Required support with an intra-aortic balloon pump (IABP) or Impella CP™
  • Subject has inadequate heart failure GDMT based on the most recent outpatient prescription prior to index admission, defined as:
  • On 2 or less of the 4-Pillar HF Drug Classes (BB, MRA, SGLT2i, and RASi)
  • If on BB and RASi, at least one of the two medications is \< 50% of the maximal target dose

You may not qualify if:

  • Underlying unmodifiable conditions that limit initiation of GDMT prior to enrollment, including but not limited to:
  • 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.
  • Known bilateral renal artery stenosis
  • Type 1 diabetes
  • o or 3o AV block, unless pacemaker is in place
  • Angioedema, hereditary or idiopathic
  • 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
  • Prolonged use (or use with complication) of Intra-aortic balloon pump (IABP) or Impella CP™ prior to enrollment, meeting at least one of the following:
  • IABP use \>24 hours if placed at the enrolling site or \>48 hours if transferred on IABP
  • Impella CP™ use \>24 hours if placed at the enrolling site or \>48 hours if transferred on Impella CP™
  • +30 more criteria
