About this trial

This is an interventional treatment trial for Cardiogenic Shock

Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  1. Subject or legal representative has signed Informed Consent Form (ICF) and the patient has the capacity to participate in the study and complete the study questionnaires, in the estimation of the study investigator.
  2. Age ≥ 18 years
  3. NYHA Class III with dyspnea upon mild physical activity, regardless of left ventricular ejection fraction (LVEF).
  4. Survive to discharge during a current hospital admission with cardiogenic shock (CS) as defined by clinical criteria previously used in cardiogenic shock trials: systolic blood pressure < 90 mmHg for > 30 minutes or requiring infusion of catecholamines to maintain the systolic blood pressure above 90 mmHg, with evidence of end-organ dysfunction such as pulmonary edema or impaired end-organ perfusion including altered mentation, oliguria with urine output < 30 mL/h, or serum lactate > 2 mmol/L (5). Hemodynamic criteria include cardiac index ≤ 1.8 L/min/m2 without vasoactive pharmacologic agents, or cardiac index ≤ 2.2 L/min/m2 and pulmonary artery occlusion pressure ≥ 15 mmHg with vasoactive agents.
  5. Patients must have internet and phone access (to allow communication of the implanted device with the researchers).

Exclusion Criteria:

  1. Technical obstacles which pose an inordinately high procedural risk, in the judgment of the investigator.
  2. Treatment with ongoing mechanical circulatory support (MCS) such as a durable left ventricular assist device (LVAD) or recipient of a heart transplantation for the treatment of cardiogenic shock during the index hospitalization for CS.
  3. If of childbearing potential with a positive pregnancy test.
  4. Transition to hospice care.
  5. Intolerance to or inability to adhere to antiplatelet therapy for 1 year after device implantation.
  6. Presence of an active, uncontrolled infection.
  7. Any condition other than heart failure that could limit survival to less than 6 months
  8. Discharge to facility other than acute rehabilitation or to the ambulatory setting.
  9. No access to internet or phone.

Experimental

No Intervention

Arm Label

CardioMEMS Implant Group

Non-CardioMEMS Implant Group

Arm Description

Following enrollment, patients randomized 1:1 to post-discharge implantation of the CardioMEMS device will receive that device ≤14 days following discharge from the index hospitalization for Cardiogenic Shock, in addition to local standard of care medical therapy.

Following enrollment, patients randomized 1:1 to post-discharge standard of care will be treated according to local standard of care medical therapy following their index hospitalization for Cardiogenic Shock.

Outcomes

Primary Outcome Measures

Hierarchical primary endpoint
Hierarchical endpoint at 6-months, including death (or mortality-equivalent including left ventricular assist device implantation or heart transplantation), recurrent cardiovascular hospitalization, health related quality of life change from baseline, measured by the Minnesota Living with Heart Failure Questionnaire (MLHFQ) as a continuous score, and change in log-transformed NT-proBNP level from enrollment to 6 months, evaluated by the win ratio according to the Finkelstein-Schoenfeld method

Secondary Outcome Measures

Health related quality of life change from baseline
Health related quality of life change from baseline, measured by the Minnesota Living with Heart Failure Questionnaire (MLHFQ) as a continuous score at 2 months and 6 months following admission for CS.hemodynamic monitor is safe in the high-risk CS population.
All-cause mortality
All-cause mortality from enrollment.
All-cause mortality or cardiovascular hospitalization
Time to first all-cause mortality or cardiovascular hospitalization.
All-Cause Hospitalization
Time to all-cause hospitalization.
Unscheduled hospital visits (including Emergency Department and Outpatient Diuretic Infusion Clinic)
Time to all unscheduled hospital visits (including Emergency Department and Outpatient Diuretic Infusion Clinic)
Change in NT-pro-B-type natriuretic peptide (NT-pro-BNP)
Change in NT-pro-B-type natriuretic peptide (NT-pro-BNP) from enrollment to 6 months follow up.
Achieved guideline directed medical therapy for heart failure
Achieved guideline directed medical therapy for heart failure with reduced ejection fraction at 6 months, measured by achievement of >50% of the guideline targeted optimal dosing of angiotensin receptor blocker or angiotensin converting enzyme inhibitor or angiotensin receptor neprilysin inhibitor, beta-blocker, and mineralocorticoid receptor antagonist.
Safety of early post-discharge implantation of a pulmonary artery hemodynamic monitoring.
Safety of early post-discharge implantation of a pulmonary artery hemodynamic monitor in the high-risk CS population, including device-related or system-related complications or pressure-sensor failures.
