Speckle-tracking echocardiography: state of art and its applications
Key result
Speckle tracking echocardiography is an important tool for early detection of myocardial impairment, predicting left ventricular remodeling after acute myocardial infarction, and guiding surgical timing.
Why the study?
LVEF has limitations including load dependency, geometric assumptions, and failure to detect early myocardial dysfunction, which speckle tracking echocardiography is hypothesized to overcome.

Implication
May support earlier post-MI monitoring beyond LVEF; leaves open prospective validation for remodeling and surgical decisions.
Key Points
- To review the current state of the art and clinical utility of speckle-tracking echocardiography in overcoming the diagnostic limitations of left ventricular ejection fraction.
- Narrative review synthesizing clinical evidence, technological developments, and diagnostic performance of speckle-tracking echocardiography.
- Evaluated myocardial deformation metrics, including strain and strain rate, across subclinical, systolic, and diastolic cardiac conditions.
- Speckle-tracking echocardiography detects early subclinical myocardial dysfunction and predicts left ventricular remodeling after acute myocardial infarction.
- Strain measurement aids surgical timing in asymptomatic severe valvular heart disease and enables early detection of cardiotoxicity in cardio-oncology.
- Three-dimensional speckle-tracking and layer-specific strain show promise for enhanced characterization of cardiomyopathies, myocarditis, and pulmonary hypertension.
