About this study

Aim 1: Prospective, observational analysis of the association between echocardiographic measures of cardiac function and left ventricular unloading on VA ECMO.

Aim 2: Prospective, observational analysis of the association between clinical laboratory biomarkers and left ventricular unloading on VA ECMO.

Read the detailed description

Mechanical circulatory support (MCS) is increasingly utilized as a means of hemodynamic support among cardiogenic shock (CS) patients refractory to optimal medical management. MCS modalities include using either an intra-aortic balloon pump (IABP), Impella®, or ECMO, each with unique benefit/harm profiles. Among the various MCS devices, extracorporeal membrane oxygenation (ECMO) is described as the highest level of support, capable of providing 5+ liters per minute of oxygenated blood flow but is the most invasive. Despite the benefit of maximal cardiopulmonary support, ECMO increases afterload in a failing heart. Left ventricular (LV) unloading or decompression (using simultaneous IABP or Impella®) has been suggested as potential improvement. Observational studies suggest a benefit with LV unloading during VA ECMO for CS, but the mechanisms underlying the association are poorly understood. Prior to trials, a mechanistic understanding of the effect of different LV unloading strategies on key physiologic abnormalities in CS is needed, as the physiologic effects of LV unloading during VA ECMO for CS remain insufficiently defined.

The objective of this study is to define serial changes in common clinical variables routinely obtained during management of patients in CS. These clinical variables are readily accessible to clinicians, but are not typically collected in a sufficiently granular serial manner to characterize their utility as clinical biomarkers. By obtaining scheduled assessments, repeated in a prospective cohort over the clinical course of CS, the investigators will define the physiologic effects of different LV unloading strategies in cardiogenic shock. We will examine a) echocardiographic measures of ventricular distension, and b) blood biochemical measures of peripheral perfusion.

Study groupRoleWhat they receive
With LV UnloadingAdults (18+) who are in cardiogenic shock and being treated with mechanical circulatory support (veno-arterial ECMO) inserted peripherally. The patients in this group will also have an additional device, such as an Impella or an intra-aortic balloon pump (IABP) for left ventricular unloading. The decision whether or not to unload the patient will be purely clinical. Data will be collected from the patient's chart and entered into a secure database. A standard complete transthoracic echocardiogram will be completed at enrollment and then again 7 days from enrollment (+/- 2 days). Additional blood tests will be ordered for the 7 days after enrollment. All tests will be ordered on Day 1 (patient on ECMO, prior to any LV unloading) and additionally as follows: * Troponin: Daily for 7 days * NT-proBNP: Daily for 7 days * PCO2 gap (in blood gas analysis): Every 6 hours for 3 days * Lactate (in blood gas analysis): Every 12 hours for 3 days * cBIN1: Twice in 7 days
Without LV UnloadingAdults (18+) who are in cardiogenic shock and being treated with mechanical circulatory support (veno-arterial ECMO) inserted peripherally. The patients in this group will not have any LV unloading device in addition to the ECMO support. The decision not to do LV unloading will be purely clinical. Data will be collected from the patient's chart and entered into a secure database. A standard complete transthoracic echocardiogram will be completed at enrollment and then again 7 days from enrollment (+/- 2 days). Additional blood tests will be ordered for the 7 days after enrollment. All tests will be ordered on Day 1 (patient on ECMO, prior to any LV unloading) and additionally as follows: * Troponin: Daily for 7 days * NT-proBNP: Daily for 7 days * PCO2 gap (in blood gas analysis): Every 6 hours for 3 days * Lactate (in blood gas analysis): Every 12 hours for 3 days * cBIN1: Twice in 7 days

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Left ventricular function (ejection fraction)

    Ejection fraction will be measured via echocardiogram and compared between time points and between groups

    Measured: Day 1/Enrollment

  2. Left ventricular function (ejection fraction)

    Ejection fraction will be measured via echocardiogram and compared between time points and between groups

    Measured: After LV unloading (within the first week of ECMO treatment; no specific day as this is a clinical decision)

  3. Left ventricular function (ejection fraction)

    Ejection fraction will be measured via echocardiogram and compared between time points and between groups

    Measured: Day 5

Secondary outcomes (8)
  1. Distension

    Left ventricular end-diastolic dysfunction (LVEDD) will be measured via echocardiogram and compared between groups and between time points.

    Left ventricular end-diastolic dysfunction (LVEDD) will be measured via echocardiogram and compared between groups and between time points.

    Measured: After LV unloading (within the first week of ECMO treatment; no specific day as this is a clinical decision)

  3. Distension

    Left ventricular end-diastolic dysfunction (LVEDD) will be measured via echocardiogram and compared between groups and between time points.

    Measured: Day 5

  4. Peripheral perfusion per lactate

    Measurements of lactate will indicate differences in peripheral perfusion between time points and between groups

    Measured: Daily (days 1-7)

  5. Peripheral perfusion per CO2 gap

    Measurements of carbon dioxide (CO2) gap will indicate differences in peripheral perfusion between time points and between groups

    Measured: Daily (days 1-7)

  6. Cardiac injury per troponin

    Measurements of troponin will indicate levels of cardiac injury between time points and between groups.

    Measured: Daily (days 1-7)

  7. Cardiac injury per BNP

    Measurements of B-type natriuretic peptide (BNP) will indicate levels of cardiac injury between time points and between groups.

    Measured: Daily (days 1-7)

  8. Cardiac injury per cBIN1

    Measurements of cardiac BIN1 (cBIN1) will indicate levels of cardiac injury between time points and between groups.

    Measured: Twice in 7 days
