Does the EF global longitudinal strain ratio improve diagnostic accuracy for detecting cardiac amyloidosis in patients with thickened hearts?
The EF global longitudinal strain ratio is an accurate echocardiographic parameter for differentiating cardiac amyloidosis in patients presenting with thickened hearts, including those with mild hypertrophy.
Our study demonstrated that in patients with thickened hearts, EF global longitudinal strain ratio has the best accuracy in detecting CA, even among the most "challenging" patient subgroups as those with mild hypertrophy and normal EF.
Pagourelias et al. (Wed,) studied this question.
