Implication
Clinical review demonstrates utility of echocardiographic strain imaging in cardiovascular disease, indicating enhanced detection of subclinical myocardial dysfunction.
Key Points
- To review the echocardiographic modalities available for assessing myocardial strain and their role in evaluating subclinical cardiac dysfunction.
- Reviewed technical principles of speckle-tracking echocardiography and tissue Doppler imaging for evaluating myocardial deformation.
- Analyzed clinical applications across components of cardiac strain, focusing on longitudinal, circumferential, and radial deformation indices.
- Global longitudinal strain demonstrates superior sensitivity for detecting early subclinical ventricular impairment compared with conventional left ventricular ejection fraction.
- Speckle-tracking echocardiography provides reproducible and angle-independent measurements of regional and global myocardial mechanics.
