Dynamic changes in echocardiographic parameters in acute decompensated heart failure: REALITY-ECHO

Area of Science:

• Cardiology
• Critical Care Medicine
• Medical Imaging

Background:

• Hemodynamic status evaluation is crucial for acute heart failure (AHF) management.
• Understanding early echocardiographic changes in AHF is vital for predicting patient outcomes.

Purpose of the Study:

• To investigate echocardiographic parameter changes in the very acute phase of AHF.
• To assess the association between these early changes and clinical outcomes.

Main Methods:

• Prospective enrollment of 271 AHF patients across four Japanese hospitals.
• Comprehensive echocardiography and B-type natriuretic peptide (BNP) measurements on admission and day 2.
• Analysis of echocardiographic parameters and their correlation with clinical events.

Main Results:

• Significant improvements in transmitral E velocity, E/A, stroke volume, and ejection fraction were observed by day 2.
• Tricuspid regurgitation pressure gradient (TRPG) and inferior vena cava diameter decreased significantly.
• Increased BNP on day 2 was associated with less improvement in transmitral flow and TRPG, and poorer outcomes.
• Combined improvement in transmitral flow and TRPG predicted reduced 90-day and 1-year composite events.

Conclusions:

• Echocardiographic parameters exhibit dynamic changes during the acute phase of AHF.
• Transmitral flow and TRPG changes may serve as valuable indicators for monitoring hemodynamic improvement in AHF patients.
