Figure legends
Figure 1. Left atrial strain measures, Doppler measures of
diastolic function, and combined atrial/Doppler measurements.
E: peaks of early wave velocity at the mitral valve by pulsed Doppler;
e’: early diastolic velocity peaks at tissue Doppler imaging; e’s:
septal e’; e’l: lateral e’; e’m: mean septal-lateral e’; LAr: left
atriale reservoir; LAcd: left atrial conduit; LAct: left atrial
contraction.
Figure 2. Cox univariate regression analyses for all the left
atrial measures , according with the presence of a reduced or not left
ventricular ejection fraction.
CI: confidence interval; HR: hazard ratio; 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.
Figure 3. Kaplan Meier curves according to the best cut-offs of
LASr and LASr/Ees.
LAr: left atriale reservoir; LAr/Ees: ratio between LAr and the ratio
between E (peaks of early wave velocity at the mitral valve by pulsed
Doppler) and septal e’ (early diastolic velocity peaks at septal mitral
tissue Doppler imaging).
