Strain Imaging Techniques in Cardiovascular Diagnostics
Summary
Strain imaging encompasses a suite of techniques that quantify myocardial deformation to assess cardiac function with greater sensitivity than conventional measures. By tracking the motion and deformation of myocardial tissue during the cardiac cycle, these methods reveal subclinical dysfunction in a range of conditions, from coronary artery disease and heart failure to cardiomyopathies and valvular disorders. The principal modality, speckle tracking echocardiography, yields parameters such as global longitudinal and circumferential strain, which correlate closely with clinical outcomes. Advances in two- and three-dimensional imaging have expanded the scope of strain analysis, enabling assessment under stress and at rest, and offering improved reproducibility over left ventricular ejection fraction. Globally, strain imaging is transforming diagnostic pathways, guiding risk stratification and therapeutic decisions, and fostering integration with other modalities such as cardiac magnetic resonance for comprehensive evaluation of myocardial mechanics.
Research from Nature Portfolio
Recent studies have demonstrated that two-dimensional speckle tracking echocardiography can detect subtle myocardial dysfunction after COVID-19 vaccination, even when conventional indices remain within normal ranges. In a cohort of vaccinated individuals presenting with chest discomfort, reductions in global longitudinal and circumferential strain were identified despite preserved ejection fraction and normal biomarkers. These findings underscore the utility of strain metrics for early assessment of transient or subclinical myocardial changes in novel clinical scenarios.
Research from all publishers
In a prospective series of patients undergoing invasive angiography, resting global longitudinal strain accurately identified significant coronary stenoses, with defined thresholds yielding moderate sensitivity and specificity for each major coronary territory. This non-invasive approach offers a rapid adjunct to conventional angiographic assessment. Elsewhere, a comprehensive review of speckle tracking echocardiography in coronary artery disease highlighted its capacity to visualise regional ischaemia and predict adverse remodelling through polar map representations. Together, these works affirm the diagnostic and prognostic value of strain imaging across acute and chronic coronary syndromes, and support its broader adoption in routine practice.
Strain Imaging Techniques in Cardiovascular Diagnostics publication trend
The graph below shows the total number of articles in strain imaging techniques in cardiovascular diagnostics across all publications each year (not limited to Nature Index journals).
Technical terms
Speckle tracking echocardiography (STE): A non-invasive ultrasound method that follows natural acoustic reflections within the myocardium to measure tissue deformation.
Global longitudinal strain (GLS): The percentage change in myocardial length along the long axis of the left ventricle during systole, reflecting longitudinal fibre function.
Global circumferential strain (GCS): The percentage change in myocardial circumference around the left ventricle during contraction, indicating circumferential fibre shortening.
Left ventricular ejection fraction (LVEF): The proportion of blood volume ejected from the left ventricle with each beat, traditionally used to gauge systolic performance.
