Systolic dysfunction in heart failure with normal ejection fraction: speckle-tracking echocardiography

Area of Science:

• Cardiology
• Echocardiography
• Medical Imaging

Background:

• Left ventricular (LV) ejection fraction (EF) and end-systolic volumes are key indicators of LV global function.
• Heart failure with normal ejection fraction (HFNEF) presents challenges as these global measures often remain within normal limits.
• Regional systolic dysfunction may be present in HFNEF, suggesting limitations in the sensitivity of global EF assessment.

Purpose of the Study:

• To explore the potential of speckle-tracking echocardiography (STE) for assessing regional systolic function in HFNEF.
• To highlight STE as a novel method for evaluating myocardial deformation in HFNEF patients.

Main Methods:

• Speckle-tracking echocardiography (STE) is an objective, angle-independent technique for quantifying regional myocardial deformation.
• STE utilizes conventional B-mode recordings to track natural acoustic markers (speckles) in the myocardium.
• STE can simultaneously measure radial, longitudinal, and circumferential deformation, as well as LV torsion.

Main Results:

• Experimental and clinical studies confirm STE's accuracy in assessing myocardial function across various conditions.
• No prior STE studies have specifically investigated its application in HFNEF.
• This article aims to demonstrate the utility of STE in the context of HFNEF.

Conclusions:

• Regional systolic function assessment may be crucial for diagnosing HFNEF.
• STE offers a promising, advanced tool for evaluating myocardial mechanics in HFNEF.
• Further research utilizing STE in HFNEF is warranted to elucidate its diagnostic and prognostic value.
