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.
