摘要
Myocardial deformation imaging is now readily available during routine echocardiography and plays an important role in the advanced care of cardiovascular diseases. Its clinical value in detecting subtle myocardial dysfunction, by helping diagnose disease and allowing prediction of disease progression and earlier pharmacological intervention, has been demonstrated. Strain imaging has been the most studied and clinically used technique in the field of cardio-oncology. A relative percent reduction in left ventricular (LV) global longitudinal strain > 15% from baseline is considered a marker of early subclinical LV dysfunction and may have the potential to guide early initiation of cardioprotective therapy. The role of strain imaging is expanding to other fields, such as cardiac amyloidosis, other cardiomyopathies, valvular heart diseases, pulmonary hypertension, and heart failure with preserved ejection fraction. It is also used for the evaluation of the right ventricle and atria. This review aims to provide a current understanding of the roles of strain imaging in the evaluation and management of patients with cardiovascular diseases in clinical practice.
