Review highlights the diagnostic value of global longitudinal strain and stress echocardiography in coronary artery disease and cardiac dysfunction.
Key Points
Global longitudinal strain shows improved detection of cardiac issues like obstructive and non-obstructive coronary artery disease, and microvascular dysfunction.
The combination of global longitudinal strain and stress echocardiography approximates the accuracy of invasive coronary angiography for at-risk patients.
This review synthesizes clinical data supporting the use of global longitudinal strain as a powerful non-invasive metric in cardiac evaluation.
Technical challenges remain for global longitudinal strain implementation, particularly regarding image quality and measurement consistency across devices.
