- •
Simultaneous assessment of LS in all four cardiac chambers was performed in patients with cardiac amyloidosis, those with nonobstructive HCM, and control subjects.
- •
LS in each chamber was significantly depressed in patients with both LVH phenotypes compared with control subjects.
- •
Four-chamber LS was significantly associated with MACEs in patients with cardiac amyloidosis.
- •
Chamber-specific strain analysis may be useful to assess the total cumulative burden of cardiac dysfunction in patients with cardiac amyloidosis.
