Study Details

Study Description

Brief Summary

More than 30% of people hospitalized with decompensated heart failure return to the hospital within 90 days. Emerging evidence suggests that hemodynamic monitoring with guided management may enhance prognosis and management. Hemodynamic monitoring with echocardiography using diastology and an evidence-informed therapeutic protocol have the potential to achieve this aim in a minimally invasive manner.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Diastology-Guided Management

Participants in this arm will undergo a focused echocardiogram every 24 hours. The degree of diastolic dysfunction will be reported to the healthcare team. If the degree of diastolic dysfunction is greater than or equal to grade 2, the research team will recommend escalating the diuretic regimen if either (1) urine output is less than 4,000 mL over 24 hours or (2) weight loss is less than 2 kg over 24 hours. If the degree of diastolic dysfunction is grade 1, the research team will recommend transitioning to or discontinuing oral diuresis.

Diagnostic Test: Diastology
We will follow American Society of Echocardiography criteria to determine the degree of diastolic dysfunction after performing each focused echocardiogram.

Behavioral: Diastology-Guided Diuresis
If the daily urine output or weight loss are less than study-specified targets, then the research team will recommend changes to the diuretic regimen based on the degree of diastolic dysfunction.

Active Comparator: Usual Care

Participants in this arm will also undergo a focused echocardiogram every 24 hours. However, the results of these echocardiograms will not be available for clinical decision-making. Instead, participants will receive usual care by the healthcare team without daily hemodynamic parameters from a study echocardiogram.

Diagnostic Test: Diastology
We will follow American Society of Echocardiography criteria to determine the degree of diastolic dysfunction after performing each focused echocardiogram.

Behavioral: Usual Care
Clinicians will rely on usual care metrics and parameters to guide diuresis.

Outcome Measures

Primary Outcome Measures

  1. Recruitment Rate [12 months (anticipated study duration)]

    This is calculated as the number of participants enrolled in the study per month.

Secondary Outcome Measures

  1. Compliance with Echocardiograms [12 months (anticipated study duration)]

    This is calculated as the number of echocardiograms completed divided by the number scheduled as per the study protocol.

  2. Interpretability of Echocardiograms [12 months (anticipated study duration)]

    This is calculated as the number of studies without indeterminate diastolic dysfunction divided by the total number of studies performed.

  3. Adherence to Protocol Recommendations [12 months (anticipated study duration)]

    This is calculated as the number of treatment decisions in the intervention arm that is aligned (increase, maintain, or decrease) with the therapeutic recommendations of the trial based on the severity of diastolic dysfunction divided by the number of studies completed.

  4. Follow-Up at 30 and 90 Days [12 months (anticipated study duration)]

    This is calculated as the number of participants that complete a follow-up visit with a study team member at 30 and 90 days, respectively.
