左心房应变的影像学研究进展与展望OA

The left atrium not only regulates left ventricular filling volume but also serves as a key biomarker for cardiovascular diseases.After the occurrence of left ventricular diastolic dysfunction,left atrial function undergoes compensatory changes before alterations in left atrial volume and left ventricular function.Left atrial strain can reflect changes in left atrial function throughout the cardiac cycle.Imaging is the only method for evaluating left atrial strain.Therefore,this article reviewed traditional and novel imaging techniques for assessing left atrial strain,including echocardiography,cardiac magnetic resonance,and cardiac computed tomography.It also introduced the application of radiomics in this field,and analyzed the reproducibility of these imaging techniques as well as the feasibility and limitations of their current clinical applications,aiming to provide appropriate imaging techniques for personalized assessment of left atrial strain in patients,offer reliable diagnostic and therapeutic evidence for clinicians,and facilitate the diagnosis,prognostic evaluation,and formulation of treatment plans for cardiovascular diseases.
