Diastology-Guided Management of Decompensated Heart Failure

Not Applicable

Not yet recruiting

• Conditions: Diastolic Dysfunction; Heart Failure

• Registration Number: NCT06131008
• Lead Sponsor: McMaster University

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.

Primary Outcome Measures

Name	Time	Method
Recruitment Rate	12 months (anticipated study duration)	This is calculated as the number of participants enrolled in the study per month.

Secondary Outcome Measures

Name	Time	Method
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.
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.
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.
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.
