Feature tracking (FT) myocardial strain analysis was performed in 87 patients with biopsy proven cardiac amyloidosis and in 64 control subjects using long and short axis ECG-triggered b-SSFP images and commercial software. Radial, circumferential, and longitudinal peak systolic strain values were all significantly different between amyloid patients and control subjects, suggesting that this technique is feasible in assessing patients with suspected cardiac amyloidosis.
