Supplementary Figure 1. ROC curves of left atrial strain
derived measures for one year events related to heart failure worsening.
LAcd: left atrial conduit; LAct: left atrial contraction; LAr: left
atrial reservoir; LAr/Eel: ratio between LAr and the ratio between peak
of E at pulsed Doppler and mitral lateral e’ at lateral Tissue Doppler
Imaging; LAr/Eem: ratio between LAr and the ratio between peak of E at
pulsed Doppler and mean mitral septal and lateral e’ at Tissue Doppler
Imaging; LAs/Ees: ratio between LAr and the ratio between peak of E at
pulsed Doppler and mitral septal e’ at Tissue Doppler Imaging.
